Attic Insulation Houston

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.

Attic Insulation & Air Sealing by First Defense Insulation

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.
Duct Insulation Houston Tx

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.

Finally a contractor I can trust! I messaged John about issues with other my primary bedroom being warmer than the rest of the house. Luckily he was in the area and came over within hours. While reviewing my cooling issues we talked about my fireplaces. I mentioned I was having issues with my bedroom one and was quoted $10k to repair. After looking at it for a few minutes he diagnosed the problem as my gas logs being oversized. He removed the larger logs and we lit the fireplace. No exhaust fumes! None. Saved me $10k!! The other contractor “misdiagnosed” my issue and was prepared to charge me $10k. How convenient. We’ve all been taken my shady contractors. John is a guy you can trust!!

Can’t say enough good things about this business. We are building our own house and had them install blown-in open cell insulation. John and his team were very professional and went to great lengths to explain the entire process and answer all of our questions. We appreciate everything right down to the small details of cleaning after they finished the job. Thanks John!

John and his crew came out and removed existing insulation in my attic and replaced it with new. The guys were punctual, polite, courteous, and did an excellent job for me, going above and beyond to ensure I was well taken care of by closing a couple of openings that rodents could gain access to the attic through and working around a few other issues we had.We can already tell a difference in how often our central unit needs to kick on and I am looking forward to seeing a reduced utility bill now that our insulation is done right.Thank you First Defense Insulation for not only treating us right, but going above and beyond. We appreciate you and highly recommend!!-Hunter Family

We’ve worked with Shad before when his crew installed foam insulation on our main house, and we were happy to be a repeat customer for our addition. He is pleasant and professional and his crew does great work. We highly recommend this business.

If you are looking to convert your home from a traditional insulation attic to a conditioned attic like I was… look no further. It started with the utmost professionalism and friendliness from one of the owners Shad, and continued all the way through the process with his team until the very end. You won’t find a more knowledgeable contractor when it comes to spray foam insulation. There is a lot more that goes into this process than just spraying the foam… and First Defense Insulation considers and informs you of all of them. The icing on the cake is how good of a job they do. You won’t have to worry if the job was done as good as it should, it will be done perfect. I crawled around every inch of my attic and couldn’t find one thing to not be fully satisfied about. I could not recommend this company more highly, and have already to my coworkers.

John and his crew were very efficient and professional! John was very thorough in explaining the insulation process and payment plans so that I knew what to expect. I have 4 people who work from home and we were thinking we would have to go into the office, but we were all able to stay at home during this process. There was noise but nothing that was extreme and once they finished over our office we could barely hear them. The crew was just amazing and so quick and efficient the first day was vacuuming and was the longest of course and then the other two days they were here at 8 and done before noon. They were always on time and didn’t waste a second. The second day the foam insulation is sprayed and there is a paint smell, but they did their best to contain it by putting plastic around the attic entrance, also we opened the windows and shut the doors of the rooms we were in and smelled nothing.Overall this was the best experience I have had with anyone who has worked on my house and I can’t wait to see the benefits on my electricity bill because we could already feel the difference after the foam was sprayed. Already our A/C does not have to come on as much. I highly recommend First Defense Installation.

I am blown away by the level of service that I’ve received from First Defense Insulation. From the initial phone call, to the in-home assessment, these guys are True professionals. Their knowledge and expertise has helped me drastically increase the energy efficiency of my home. John showed me the many areas of my home that were seriously lacking, and how I can address those issues. They put together a plan that really improved the comfort inside of my home. I could not be happier with their service. The work was clean, and everything went very smoothly with the job. I highly recommend them!

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.

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.

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 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!!!

John and his team did a outstanding job at my house. Answered all my questions before during and after the whole process. The guys arrived on time everyday and cleaned up after themselves unlike most companies. They were very polite and professional the whole time. I already noticed the difference in how much less my A/C unite runs now. I highly recommended first defense to my family and neighbors. Thanks guys

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. I don’t plan on building another house but If I do… John and his crew will be the ones to do it!

We had our roof replaced by John and his team , and could not be happier. He was on time for all his appointments, very thorough with his initial inspection, and took his time not only showing us the pictures and videos he took but explaining it all. Job was done as agreed to and all dates where met I highly recommend as you will not be disappointing.

I have contacted First Defence Insulation after I found them in google. And John was able to make an inspection appointment the very next day. Even though the supposed personal couldn’t make it to the appointment, John drove all the way from Houston to Dallas to fulfill his word and make it happen, instead of canceling on me. I appreciatte his respect for Customers and his level of knowledge when it comes to how the airconditioning and heating systems work in making the home comfortable while saving energy costs. During the inspection he crawled in to very tight attics and checked everything that needs sealing. Also he brought different demonstration materials to demo for me how insulation works in the attics. And stayed almost 6 hours just for a free inspection. Unfortunately I had a change of plan and haven’t continued his the project. But as far as I can tell from the inspection John is really communicative and professional. And I recommend him and his company for insulation projects and making your home comfortable.

Our complete attic insulation services

Is your house too hot in the summer and too cold in the winter? When your attic is under-insulated, it lacks the thermal barrier your home needs between the living space and attic. Installing blown cellulose insulation to meet recommended insulation levels will help prevent air flow between the two spaces, ensuring the air you pay to heat and cool stays in the living space.

Insufficient insulation forces your HVAC system to run longer to get your home to the right temperature, which is obviously an expensive process. When your home has the recommended insulation levels, your furnace or air conditioner will be able to get your home to the temperature you want as efficiently as possible.

A common home comfort complaint is that there’s one or two rooms that just won’t seem to cool down in the summer and warm up in the winter. Poor air sealing and attic insulation are often the cause of these problems. An air leak in that attic will affect the room directly below it most significantly, but it will also impact the overall home. For this reason, it’s important to have consistent air sealing and insulation throughout the attic.

You can often tell if you have enough attic insulation just by looking at it. The U.S. Department of Energy recommends having between 13-18 inches of insulation, depending upon your local climate. According to the Insulation Institute, 90% of homes in the U.S. are under-insulated, and there’s a good chance yours is too.
