Attic insulation upgrades improve 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 Services

Maximize HVAC performance and energy efficiency with quality duct insulation

Most homeowners are aware of the importance of their furnace, air conditioner, and insulation for their home’s energy efficiency, but too many homeowners forget about their ductwork. Uninsulated, leaky ductwork will cause your HVAC system to be inefficient and will negatively impact your home’s comfort, especially if the ducts are in the attic.

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.

Fantastic customer service. I had a small urgent need during a renovation I discovered about 90 sqft of exterior wall left uninsulated. John went above and beyond to squeeze me in on a Friday evening. I highly recommend.

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!!!

There are many positive things to say about First Defense Insulation. They were courteous; prompt; they kept me well informed during the course of the repair. Hands down they were the best choice from other competitors in the local area. I would call them again first for their services should the need ever arise.

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.
