Attic Insulation Improves Home Comfort and Energy Efficiency
When your attic lacks the proper attic insulation and air sealing, the effects on your home’s comfort and energy efficiency are significant. An attic that doesn’t meet insulation standards will lead to high heating and cooling costs, uncomfortable rooms, and uneven temperatures throughout your home.
Expert Attic Air Sealing
Gaps and cracks in the attic are an unavoidable part of home ownership. There are several reasons why these spaces form, but every home is subject to the air flow that can occur through these areas. Without proper air sealing, this air leakage will negatively impact your home’s energy efficiency and comfort.
Under-Insulated Ducts Cause Homes To Be Less Comfortable and Waste Energy
Most homes attic and crawl spaces are not kept conditioned. Duct work in these areas will match the outside ambient temperature, which is much hotter or colder than the rest of the home depending on the season.
Duct insulation and encapsulation improves home comfort and energy performance by protecting the air temperature inside the ducts from the outside environments.

Knowledgeable, professional, flexible. They look at the problem and make sure the solution doesn’t inadvertently create another issue. That’s very helpful when dealing w insulation, floors, attics, HVAC, and overall structure.

Had open cell foam sprayed into our MASSIVE attic. Very expensive but it completely transformed the attic. It used to be extremely hot and felt dirty and dusty. Feels like part of the house now and is much cleaner (they remove the old “blown in” insulation as part of the job). We’re looking forward to seeing our first electricity bill with the new insulation.Communication was fantastic throughout; before, during and after the job. They addressed our concerns, thoroughly explained the process and what to expect, and kept us informed of progress while the job was being done. When the job was done the house was left spotless. I highly recommend these guys for your insulation work.

The staff of First Defense Insulation was on time, professional around me and my children, very time efficient the whole time they were at our house working. Eddie and the other young man did an amazing job at insulating our home, now we can stay cool in this Texas summer and warm in the winter!

We met with John Harper and his associate. They were so professional and explained every step of the insulation process. Prior to this we did not realize the importance of starting with the attic and to be sure it is up to the standard in order the the AC to work to the best of its ability. We haven’t had the work done yet and will review again but making me this huge financial decision and feeling comfortable already is a huge relief. Look for another review after the work is complete. John still as so professional and walked us through every step of the process.

We needed someone to insulate my late mother-in-law’s house, which was built in 1941 and had never been insulated. John and his assistant met my wife at the home and spent over an hour thoroughly inspecting the attic and crawl space. John delivered our options and his recommendations in layman’s terms as we know very little about insulation. He responded promptly and thoroughly to emailed questions.We decided to have the sprayed foam insulation installed, and to take advantage of the one year same as cash financing option. That worked smoothly and quickly, with same day approval and John’s crew able to begin work the next day. They worked diligently, and finished the job a day ahead of the projected schedule. The foam was applied cleanly, and the crews cleaned up after themselves so that the only clue they had been there was the new insulation. John checked on the crews as they worked, and came out the last day and inspected the job himself to be sure it was completed as he had said it would be. He sent us pictures and video of the work as it was being performed, and kept us informed of the progress each day.Today, when we were there, the entire house was able to be cooled and kept very comfortable with only one of the five air conditioning units in the house. The difference was phenomenal.We are definitely pleased with our decision to insulate, and to use First Defense Insulation to do the job. They were thorough, honest, competent, and all we could have hoped for. We know who we will call if we ever need an insulation company again.James and Dwana NowakLufkin, Texas

After researching a number of companies, I selected John and his team for a big job removing the old insulation under our house and then spray foaming. The level of service from the time of our first meeting to the completion of the job was awesome. They finished faster than expected and left our home looking just like before they started. I would definitely recommend this company – great owners and team.

We had some last minute design changes in the shop loft that impacted the insulation envelope. John adjusted the foam schedule accordingly on short notice. Super fast response to all of our calls.The insulation looks great! It is very comfortable inside, even without air conditioning.The First Defense team cleaned the concrete foundation and bagged the scrapings, the foam shavings, and fiberglass scraps. Our site was clean when they left.We highly recommend First Defense Insulation!

We needed to have some blown in insulation removed from our attic & our contractor recommended First Defense. We called them & set up an appt., & John came out & looked at the job we needed done, & gave us a quote. We knew shortly after we met him, that we wanted First Defense to do the work, & we couldn’t be happier with the job they did!!! His guys showed up early, & they got to work right away. They were all very professional & cleaned up after they were finished. We will be calling them again soon to do an even bigger job, & we look forward to an even more energy efficient home once that job is completed. Thank you John & Shad for making this such a pleasant experience! it was great meeting both of y’all, & we look forward to working with y’all again after the first of the year!!!

I’m very very impressed with this company. I hired First Defense Insulation to come out to air seal, and insulate my attic. John came out with his crew to make sure the job was done correctly, and was working along side his employees doing the work. They did an awesome job. I would strongly recommend this company to anyone who needs a insulation job, rather it be a new house or older house, they do a great/professional job. John is very patient and understanding with his customers, he takes the time to listen and analyzes the problem/issue at hand, and then comes forth with his recommendations. Trust me, when John says that his company is going to do this or that, they absolutely will do it with no questions or exceptions. First Defense Insulation is very fair with their pricing. After the job is done, you would see and agree that they are worth every penny spent.

We called John about having our new home insulated. He came out, was very professional, answered all of our questions (and I had a lot)He sent us a very competitive quote. We called to let him know we were ready for the work to be done and he said they would be there with in 3 days!!! Not weeks like the other quotes we had gotten. The crew showed up right on time! Very professional, and did an amazing job!!! They even cleaned up and swept the house out. I could not have asked for a better experience with a company.
