Please read this for YOUR protection, and our SAFETY. Thank you. This will help you to know WHAT TO EXPECT from us, and what we Expect from you. Most installers will not share these items with you even though these are the rules they play by. We like to be up front and communicate with you for full transparency.

At Stellrr, we go above and beyond industry standard practices to deliver the highest reasonable level of service while maintaining very competitive pricing.

By hiring Stellrr, you the Client are accepting, agreeing to, and promising to comply with the following Terms of Service:

Agreement: Your estimate’s “Description” line items and Stellrr’s Terms of Service constitute the entire agreement between the Client and Stellrr, and no terms, conditions, or understandings, whether expressed or implied have been agreed upon except as expressed in the estimate Description line items and in the following Terms of Service. If you do not accept the terms of service then do not use Stellrr.


1. Invoicing & Payment.

A $500 deposit is required to Accept the Quote and be placed on the Schedule (deposit may be waived required for repeat clients only). Upon arrival on the job site for the install, 50% of the total is due before work commences. The final payment is due within 24 hours of **substantial completion of the work**.  Any discounts or coupons shall be negated if any amount becomes past due.

Please pay your $500 deposit here:

1A. Time Sensitive.  

Overdue invoices are subject to late charges. A reminder notice will be sent at 10 days past invoice date. With a letter sent at 30 days if not paid.

1B. Collections.

Client shall also pay to Stellrr Insulation a late charge of 1.5% per month on all balances unpaid 30 days after the invoice date. If there is any dispute regarding money due to Stellrr, the client must still pay all other charges (not in dispute) immediately. If client fails to pay on time and Stellrr refers your account(s) to a third party for collection, Stellrr will charge all costs associated with the non-payment, including but not limited to, accumulated late fees, return check fees ($30.00), insufficient funds fees, collection agency fees, and court and attorney costs. Stellrr will try in every attempt to collect in house, but if all attempts are failed Stellrr may file a lien against the property, file for theft of service judgement, and refer account for third party collection. Any discounts or coupons shall be negated if any amount becomes past due.

1C. Forms of payment.

Checks or Cash may be accepted in person or mailed to Stellrr Insulation, 401 Congress Ave. Ste. 1540, Austin, TX 78701. Stellrr accepts credit cards for 3.5% additional cost. Stellrr passes on to you the added cost that the financial institution charges Stellrr to process payment via credit card.

2. Changes.

All work will be performed in accordance with this signed proposal and the corresponding work order. Items outside the scope of accepted proposal and the corresponding work order may be added in the form of an Additional Work Order. No handwritten changes may be made to either the scope, specifications, or pricing contained in the proposal once it is signed and accepted. All changes to the proposal must be made and initialed by the Client prior to signing. Verbal changes or additions of any kind will not be honored. A Change Order fee of $147 will be assessed to each change to the original Estimate. 

3. Estimates.

In creating estimates Stellrr does our best to create an accurate scope of work and pricing. However, on occasion the project information received proves to be inaccurate. This renders the project scope, price and performance estimates incorrect, null and void. To ensure accuracy, the Stellrr team preforms a pre-project “walk-around” before work commences. The team verifies that the project dimensions and information match the scope of the Work Order.  If the information matches, the team will start the work. If there are inaccuracies, the team will notify your Stellrr representative so that the actual scope of work and revised price quote can be created. Your Stellrr representative will notify you of the Change Order for you to accept the actual scope of work and pricing. Should you decide to not proceed with the project, your deposit will not be refunded and you may be assessed a trip charge of $1.95/mile.

3A. Porches & Garages.

All estimates EXCLUDE porches and garages, unless explicitly listed as a separate line item. When installing foam, if your attic connects to a porch, or garage, a pony wall must be built and insulated to separate the semi-conditioned space from the outside space. We are happy to add separate pricing porch or garage insulation.

3B. Roof Deck Scope Details.

Roof deck spray foam quotes always exclude porches, balconies, and the garage. A pony wall must be built from the rafter to the attic floor joists. Stellrr will spray the pony wall to separate the inside (conditioned) space from the outside (unconditioned) space as required by building codes. Walls in attics will be sprayed at R-13 as that is the code for walls. Walls in attics will not be sprayed at the R-value of the roof deck. 

If you require a in-attic door to move between your conditioned attic, and your unconditioned porch or garage, Stellrr advises you to have one installed before we arrive. If client does not have the pony wall built for Stellrr, a charge will be assessed of $87.00, plus $1.50/sq ft for constructing a barrier to spray against.   

3C. Unforeseen Work.

Our initial estimates include the cost for expected plastic protection, scaffolding building/rental, the job site fee, and other items. If Stellrr is required to do unforeseen work or redo any of the following, an additional charge may be incurred for: 1. scaffolding re-build/rental $75 per 6ft section, 2. re-install plastic to protect windows and doors $297 minimum, 3. install plastic on walls or floors $297 minimum (usually retrofit in finished buildings), 4. cut into sheetrock/wood to install/remove insulation $297 minimum, 5. extra job site trips $197, 6. shave foam from cathedral ceilings $297 safety hazard work fee.

3D. Job Site Fee.

All trips to the job site are subject to the $197 per trip Job Site fee to cover our expenses. The project estimate includes the number of trips we require to get the project done. If Stellrr is required to come back after significant completion, a Job Site fee applies each trip. If we come out to install, and the job site is not accessible, or not properly prepared, a job site fee would apply. If more than 1-trip to the job site is requested before installation (usually project design related), then a Job Site fee applies to each trip (unless the Client is paying for Project Design Consulting).

3E. Project Design Consulting.

Some Clients require 1-on-1 professional advice in deciding what to do on their project. Or they want to request multiple quotes, revisions, or play with multiple options. In this case, Stellrr charges $100/hr with a $200 minimum for design consulting. This can be a great option for ambitious Do-It-Yourselfers, or people looking to do retrofit soundproofing in existing structures. 

3F. Site Cleanup & Trash.

Upon completion of a project, product waste will be bagged for disposal into the onsite dumpster by the Stellrr team. If a dumpster is not readily available onsite, or is full, product waste will be bagged and left on site in a place where it will not blow away. If client wants Stellrr to haul removed materials, the charges are as follows: 

       Truck bed disposal of insulation removed from job site $200 each trip.

       Rental of dumpster for disposal of insulation removed from job site $400 each trip.

Please note that NO removal of old insulation or other materials is included with any installation quote. Removal will only be done if stated as a separate line item on your estimate.

4. Preparation.

Plumbing, electrical, and mechanical work must be completed and pass inspection before insulation can begin. All utilities must be secured as per code to avoid any distortion or expulsion from the cavity as the insulation expands. 

All building enclosures and walls must be installed prior to Stellrr’s arrival. This includes the Client closing all openings greater than 1/2-inch where the foam would spray onto the outside of the building.  

4A. Garage Interior Walls and Interior Sound Attenuation Walls.

Sheet rock must be installed for the garage interior walls shared with conditioned areas. If the garage is attached to the house, a pony wall must also be built and sheet rocked in the attic. The fire & building codes requires that the garage attic be separated from the house attic. Also walls used for Sound Deadening that will be insulated with foam must have sheet rock installed on only one side.

4B. Access.

Stellrr trucks and trailers require access to the install area (75ft or less).  The drive path must be solid so that the truck and trailer do not get stuck. The access must allow for a 12ft tall, 9ft wide, 25ft long trailer to be maneuvered into place by a 22ft long truck.

4C. Clear Out Building & Overspray.

Client is responsible for completely clearing the building of ALL valuables, equipment, materials and debris and remove all other items from the work area. Any items left in the building may get insulation stuck on them permanently or temporarily. Stellrr is not liable for any damage whatsoever. Client acknowledges that anything left in the building (including plumbing trenches, and building materials) is a safety hazard for Stellrr’s workers. If items are left in the building that Stellrr must remove, Client may pay $100 per hour for removal and reinstallation.

4D. Nail Removal for Trimming.

Client must remove all nails, screws, staples the wall studs or ceiling rafters before Stellrr undertakes work, to allow for trimming of the insulation flush.

4E. Protection.

When spraying foam, Stellrr will mask all windows and doors to protect and reduce overspray. Stellrr will not mask the walls, floors or ceiling with plastic. Stellrr will trim foam flush with wall studs (unless agreed otherwise).

5. R-values / Thickness.

Due to the nature of foam and other materials used, Stellrr is unable to guarantee the exact output. Spray foam does not apply to exact depths, this is neither a defect in materials or workmanship.

All R-Values/Thickness depths in quoted/contracted are Averages (nominal fill), not minimum. The nominal thickness is plus or minus 1-inch. 

If 90% of the project meets the nominal thickness, then it is considered within the approved specifications. If some areas have significantly more than the nominal thickness installed, other areas may have considerably less thickness, and this is appropriate. 

Do not be concerned if depths of foam vary greatly. The depth of the foam is less of a concern than with other products.

The performance of the building will be minimally impacted by the depth, as the biggest benefit of foam is the air infiltration sealing ability. 

The ultimate determination of how much foam was installed will be determined as follows: 

The manufacturer’s specifications state how many board feet (1 sq ft area, 1 in thick) are made out of each gallon of materials. 

The material installed is measured by the Graco Proportioner computer which pumps out the material and is the brains of the foam rig. 

Stellrr will installs the correct number of gallons/pounds of material. If the project requires more gallons than included in the estimate, Stellrr will consult the client about making a change order to add more materials, and achieve the clients goal. 

Stellrr sells and installs foam, ultimately by the gallon/pounds, according to the manufacturer’s coverage and yield Technical Data Sheets. 

Open Cell Foam is called 0.5 pound foam because at the stated R-value per inch (R3.6 – R4.0), it will weigh .5 pounds per cubic foot. A cubic foot is 12 board feet (12”-wide x 12”-deep x 1”-thick). So a bd ft of open cell foam would weigh .04166 pounds each.

Closed Cell Foam is called 2.0 pound foam because at the stated R-value per inch (R6.4 – R7.1, it will weigh 2.0 pounds per cubic foot. A cubic foot is 12 board feet (12”-wide x 12”-deep x 1”-thick). So a bd ft of open cell foam would weigh .16666 pounds each.  

Two 55 gallon drums of foam is called a Set. The weight of material in the drums is 500lbs and is 50 gallons. So spraying a set of material is 1,000 pounds being installed.

Here is the formula for calculating 1,000 pounds of foam installed equals:

  • Open Cell 1,000lbs / 0.5lbs per cubic ft x 12bd ft per cubic ft = 24,000 bd ft per set or 240 bd ft per gallon. 
  • Closed Cell: 1,000lbs / 2lbs per cubic ft x 12bd ft per cubic ft = 6,000 bd ft per set or 60 bd ft per gallon. 

Stellrr ultimately sells foam to the Client by the pounds/gallons installed.

We can accurately measure the number of gallons installed on your project. We cannot measure how many inches are hard to account for because of metal corrugations, wrapping around rafters, filling hidden cavities, and much more. 

Our costs to to do your project are tied up in the materials installed. We will install the correct number of pounds of material over the estimated sq footage. We cannot guarantee the depth of the foam. If you desire more depth, we are happy to continue to sell it to you by the pound / gallon of material installed. 

6. Scheduling Projects.

Start dates cannot be guaranteed by Stellrr as there are many variables in the construction process outside Stellrr’s control. Examples include weather, material allocations and shortages, workforce assignments, work backlog, job-site delays, etc. Stellrr will contact Client to schedule a tentative start date AFTER the Client signs Proposal and pays the Deposit Invoice. 

  • Client will be provided with a 4-hour crew arrival window on the project start day. This window is usually 8:00AM-12:00PM or 12:00PM-4:00PM. 
  • Client will also receive a installation days timeframe. For example if we believe it is a 1-day project, you will be told 1-2 days. If we think it is a 3-day project (if everything goes perfect) then you will be told, it is a 3-6 day project. Our goal in this is to help you schedule other trades and deliveries. We don’t want you to feel pressure from overcommitting. While we are installing foam, no other people can enter the building and no deliveries may be made inside the building. This is a an OSHA rule. It is also for the safety of your materials being delivered and protects against fall/trip hazards.
  • Please DO NOT schedule other trades to come in until 48 hours after the last day of our project time range. 

7. Health & Safety.

From the start of the install process, until 24 to 48-hours after completion NO unprotected persons may enter the building. Persons entering the building must be protected and wear full safety gear including respirators to protect them from inhaling dust, fumes, vapors, etc and be accompanied by a Stellrr representative. If foam is being installed in a home, residents must vacate the building from start of install, until 24 to 48-hours after completion. The HVAC until must be turned off by the Client.

Please review our Health Compliance, Safety Data Sheets, and Hazard Communication program.

8. Ignition Barrier & Thermal Barrier.

Ignition & thermal barriers are often required by building codes on spray foam where the foam is NOT covered by a thermal barrier such as drywall or DC-315. Stellrr’s open cell spray foam does HAVE an ignition barrier woven throughout it. Closed Cell spray foam does NOT have an ignition barrier in it. Depending on the building codes, application, and use of your space, you may require a 15-minute thermal barrier like DC-315 coated on top of the foam. Insulation quotes do not include the cost of DC-315 unless explicitly stated in a separate line item.  If Client does not require Stellrr to install an ignition barrier or thermal barrier, Client waives Stellrr from any and all liability, errors, and omissions. Seek advice from your local Code Compliance Official or Fire Marshall for their requirements in your specific situation. 

9. Sealed & Vented Envelope Requirements.

Consult your HVAC tech regarding ACCA Manual J & D requirements as well as ASHRAE standards for ventilation. In general, when installing spray foam, the building envelope must be left vented (open) UNLESS the HVAC unit is 90% or greater efficiency and has a de-humidifier . If the water heater is in the building envelope, it must electric or modified by a licensed technician for proper ventilation outside. Unless explicitly directed by the Client, Stellrr will leave the building envelope open and vented. If Client directs Stellrr to seal the vents in the attic, Client accepts all responsibility and releases Stellrr from any and all liability, errors, and omissions. Consult your HVAC contractor for information about ventilation standards and equipment requirements. 

10. Client Proposed Modifications to National Insulation Association Standard Operating Procedures.

Stellrr will take under advisement client suggested changes to our operating procedures. Stellrr may or may not adopt the suggestion. There are many factors to consider that the untrained person cannot foresee. Stellrr will preform them as they see fit under their professional opinion of industry best practices. Stellrr intends to keep projects on time, and may modify our processes to best accommodate internal and external demands at our discretion.  

11. Disagreements & Disputes.

If the client has a dispute or disagreement with Stellrr regarding work proposed, work done, added work, or any invoice, the client must immediately pay the items and amounts NOT in dispute. The item(s) of disagreement can be worked out over time, but undisputed payment owed, is due within 24-hours of Stellrr leaving the job site. 

12. Defamation.

If a client or prospect is in disagreement or frustrated with Stellrr, Client agrees to seek appropriate private resolution with Stellrr. Client will not post negative comments or reviews about Stellrr or it’s representatives on social media. If client breaks this covenant, client agrees to pay for damages, starting at $300. Likewise, Stellrr agrees to professionally handle any frustrations with the client directly to their face, and not harm their reputation carelessly. 

13. Damage Waiver.

Client provides full release of liability resulting from damage, not limited to, but including: drywall, HVAC system, duct work, electrical, framing, windows, doors, handles, and other items.  Due to the nature of the work, especially in retrofit applications, the installers will be working in confined spaces with extremely limited access and ability to see or move. For example, to crawl through the attic of a home that is drywalled, the installer could crack the drywall because it is not possible to properly see, move, or feel the beams, lights or other fixtures in the attic. If Stellrr does indeed significantly damage anything while working on your project, we will attempt to repair it, up to $100.00 in cost. If an outside company is hired to repair or replace an item, they must be chosen by and hired by Stellrr and the maximum contribution from Stellrr will be $100.00.  If a company is hired without Stellrr’s explicit written approval, Stellrr will only contribute up to the dollar amount, and for the scope of repairs that are approved by Stellrr’s chosen repair/replacement company.


14. Inspection & Callbacks Post-Install.

Stellrr wants you to be very satisfied with our work. Stellrr request that the Client to be present for a Post-Install Inspection BEFORE Stellrr leaves the job site on the day(s) of installation. The purpose of the Post Install Inspection is for the Client to find any areas that are not as they desire (within reason). Stellrr will address the items while still on the job site.

If Client is not present to inspect the project while Stellrr is still on site installing, then the Client approves the project AS-IS and WAIVES their right to a callback. Regardless, in the rare case that Stellrr’s insulation installed does not pass a require municipal building code inspection, Stellrr will come back and fix the issue to the inspector’s requirements. This obligation is contingent upon; the reason for failing the inspection was due to an item included in the accepted Stellrr Install Estimate & Scope. 

If a Client has an acceptable callback, the request must be made within 5-days of final install day. If Client requests a callback unrelated to passing a code official’s inspection, or after having okayed the sprayer’s work, then a Job Site Fee will be applied to each following trip made to the project, any additional insulation to be installed will be charged by the gallon installed, and fees for using and installing more protection materials will be applied. 

Thank you for your business and please remember us for all your projects!
