Was able to come out next day to patch my roof that was damaged by the hurricane. If you are need of high quality, professional work, this is the company for you. Thank you again.Trustindex verifies that the original source of the review is Google.SAUL ORTIZ2024-06-28I am more than blessed to have contacted John at First Defense Insulation. I had a tree fall on the house causing a huge hole in the roof allowing rain and debris to come into the home. John had someone come out and tarp the roof to prevent further damage and immediately got to work on the repairs. He didn’t cut any corners and made sure the replacement parts were matched to the existing parts such as paint, soffits, trimmings, etc. He was out there making sure everything was done to his liking and if there was anything off and he didn’t like, it was done again until it was done right. Truly the best experience I had knowing that I didn’t have to be present to make sure it was done correctly. John is a man of integrity and someone who will treat your home as if it was his own. You will not regret calling First Defense for your roofing or insulation needs!!Trustindex verifies that the original source of the review is Google.Brandi Pumphrey2024-06-22Our experience with First Defense was amazing.

John responded to my inquiry very quickly and even came out for a quote during the weekend. When it came time to do the job, the crew showed up on time, and with a supervisor who helped ensure that the job went smooth from start to finish. The supervisor texted me photos, videos, and progress updates throughout the day, which provided great peace of mind. Definitely would recommend to a friend. You might be able to find a cheaper quote somewhere else, but you won't be getting the same quality of work, communication, customer service, and punctuality. Save yourself the headache and hire these guys.Trustindex verifies that the original source of the review is Google.RYT Construction2024-01-03John is one of the most professional and punctual guys I know.

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.
Frequently Asked Questions
Insulation plays a vital role in regulating the temperature of your attic, helping to maintain comfort throughout your home. It acts as a barrier to prevent heat from escaping during colder months and keeps your home cool in the summer. Proper insulation can also reduce energy consumption, leading to lower utility bills.
Choosing the right insulation for your home depends on Houston’s unique climate. Different materials, such as spray foam or fiberglass, offer varying benefits in terms of energy efficiency and cost. We’ll help you decide which option is best for your home and budget.
The amount of insulation required varies depending on the size of your attic and the specific needs of your home. Ensuring the right level of insulation can optimize energy efficiency and prevent air leaks. We’ll assess your attic and recommend the ideal insulation thickness for the best results.
