"We previously had Top Gun Attic Pros replace the fiberglass insulation in our house attic. The work was incredible, the product was perfect and they were great people to work with. We were so impressed that we told our contractor that we would select our own spray foam installers (of course it was Top Gun Attic Pros) for the barn we were building. Once again John and Top Gun exceeded our expectations. One thing I didn't mention was that their pricing was VERY competitive, but I would have paid a premium for their quality of work."

"My 1950, 860 ft house had 20+ yr old dusty, pink insulation, that was even worse after the city revamped utility vaults & pushed rats into the neighborhood. I chose S.R Insulation to vacuum out, caulk open voids, and re-blow insulation. The owner set up an appointment quickly. On the day of service, he did call 15 minutes late to advise of an issue. The 3 person team arrived within an hour, set up the vacuum and bags, then removed insulation; original, wood-shingle slips; and ducting left by A/C techs. They worked between 3 to 4 hours and said they would return next business day. The two part installation, gave me an idea - I asked for an extension, so I could repair ceiling sheet rock while the attic was void. The owner agreed. He did not require partial payment. Three weeks later, I rescheduled. The install was even quicker, filling up to the stud height in white, blown insulation. He leaves behind a cardboard measuring stick to show you. The difference inside the house was immediate. I will not provide calculations, as I added front load washer/dryer to the electric usage at this same time. Later, I found my stove top vent fan blocked. I was able to pull out material from the duct, and the fan worked. Therefore I did not call the owner about this. I paid less than $1500, and thought it fair. I would use S.R. Insulation again and recommend them."

"I live in a old house, and the insulation on the attic needs to be added.  City of Austin Utilities (Austin Energy) has a great rebate program for insulation, so I signed up.  EnergyAttic is one of the companies listed by Austin Energy.  For getting the quote, the audit person was friendly and through with his explanation about what's and why's.  Finally I scheduled for the work.  Kent came with his crews and basically supervised and worked on the problem and the insulation.  He made sure everything was installed (seal, insulation) properly and Austin Energy auditor approved the work.  The door blower/blast test took a while because of setting issue (EnergyAttic subcontracted to other company), and finally after 3 hours, we did get an excellent result.  I was happy with Kent's and his crews work.  They were friendly, punctual, and got the work done.  They actually came back to reseal door on the furnace area.  They also promised to come back if  I were to work on the attic and the insulation needed to be re-sweep."

"The folks at DFW Home Insulation were great from start to finish. Allison handled all the scheduling and was very responsive. Jeremy came out for an estimate on Thursday, was prompt and professional, and had a quote ready right away. It was a very competitive so I signed up and they were able to come out and install my new attic insulation 2 days later. The day of the install they were were very prompt. The install took a little longer than expected because my house required some additional prep work, but they communicated with me about the extra time needed. Overall very pleased with the process and would absolutely recommend this company to anyone looking to have extra insulation added to their attic."

"Lance came out and gave me a bid for adding insulation in my attic along with a solar attic fan. I was very pleased with the whole process from the initial bid to the final product. We are waiting on better weather to add the attic solar fan. I could not be more pleased with Lance and his company employees. I will only recommend this company to others in the future. It's always a pleasure to deal with courteous and professional contractors

"Stuart is very knowledge about HVAC units and tries to repair versus replacement.  Extraordinary customer relations.

 Also scheduled adding new insulation.  His work is reliable.   We had a few hiccups on the timeline of getting replacement unit installed due to call load. We plan to use him for normal maintenance going forward.

"Trevor and Jon responded to the call the fix our air conditioner that was still blowing, but not cooling. They did a wonderful job and went over and above by cleaning the units and performing a quality check that was over due. We are club members, so the cost of service was very reasonable. Yes, we will use them again."

Insulation questions, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

Sometimes you may be able to leave the bags with your regular trash. However, that’s not always the case. Call your local waste management prior to starting the removal and ask about the proper ways to recycle or dispose of removed insulation. In many cases, your town or municipality has a designated dumpster for building waste.

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.
