Popular Crawlspace Upgrades

Is it worth getting these upgrades?  It is considering the amount of moisture that enters your home via the crawlspace. In fact, 40% of the air in your home comes up from the crawlspace. It wicks the moisture up from the dirt, even when we are in a drought. A nasty crawlspace can lead to serious health problems.

Earlier this year, my wife and I hired Stellrr to remove all the spray-in [loose fill fiberglass] insulation from our attic and come back in with deck foam spray. Our goal was to resolve an issue with condensation that formed on the 1959 metal ductwork which pooled and created leaks in our ceiling. Our attic is now approximately 10 degrees warmer than the interior of the home.  It's now summer with temps hitting 100 degrees in central Texas and we could not be happier.

After getting multiple bids with a huge disparity in quotes I opted to hire Stellrr and am very happy I did! Both Wayne and Shawn were very helpful and informative in choosing the best option for my attic space as well as providing great customer service!

We highly recommend family owned Stellrr Insulation. They covered [and air sealed] our can/ recessed lights added additional spray foam insulation for us and sealed up our home to save us $$ and keep it cooler and warmer. We were so impressed with their professionalism and their follow up. NO harmful chemicals. We got immediate callbacks and personal meetings. Shawn, Wayne, Shelly & Violet took great care of our family.

The Stellrr team did a stellar job with the install spray foam insulation in our attic. I had measured temperatures on the attic side of the metal roof to be over 130 degrees! I just checked again, and now it's 75 degrees without air conditioning it! All of my questions were answered in detail and the job went without a hitch. The temperature in the house is much more stable because of the air barrier. The HVAC comes on much less frequently...

The estimating process was transparent and efficient; the pricing fair (you are paying for excellence); customer service as friendly as could be (Stellrr even brought me back lunch on the first day); and the workmanship first rate, with a rare level of conscientiousness and attention to detail. Great friendly crew. Seriously, don't spend time shopping around: just select Stellrr .

Stellrr did an amazing job on insulating my completely gutted "A" Frame [cathedral ceiling] house. I had some special requests and they didn't complain, the just foamed it up. After the remodel the electricity bills are 1/2 of what they used to be. Also it is so quiet, I can't even hear it raining on the roof [because of the spray foam encapsulated attic and roof spray foam insulation in Austin]. The temperature stays very steady and the whole house is always comfortable.

Commonly Asked Crawlspace Questions

According to statistics from EPA's Energy Star Association, energy bills can be cut by 30-50% with a properly sealed building envelope versus a vented one. The initial cost of the spray insulation should be seen as an investment as it will pay for itself over time.

Absolutely! Depending on how much groundwater we are trying to manage, we may or may not need several aspects of the Basement Systems CleanSpace Encapsulation. When you meet with your Solution's Specialist we will make recomendations as to exactly what is needed to solve the problems you are experiencing. 

The price depends on the size of the crawlspace, scope of work required to do it right, and the difficulty of the work. We have fixed pricing and do not charge more for nicer parts of town. Everyone gets the same rate. With that said, you can see the 3 main project types pricing above. 

Sure. You could. But each person who has tried DIYing it, has told us what a mistake it was. It is so nasty in crawlspaces and very hard work. Plus you really need the right equipment. We use a $150,000 spray foam rig to install the closed cell foam. And when doing removals we use a 23 horse power vacuums and blow it into large dumpsters. People who DIY have used shop vacs and can foam. The difference is 1,000 sq ft per day of work accomplished versus 100 sq ft per day DIY.

Stellrr accepts payment via cash, card, check, and easy financing. On our financing you can pay a low monthly payment or get the loan and pay no interest. Your Solutions Specialist can review the options with you in person.

The good news is that what we do will pay for itself in time. Unlike most other home repairs. We do have a Smart Money Guarantee. It states that you will save the cost to retrofit your home within 10 years, or we will REFUND YOU THE DIFFERENCE. For more details, check out the Cost of Not Hiring Stellrr FAQ page.
