"Remy got the job done in one day as promised. He installed baffles to protect the air flow from the soffits, installed the insulation and even discovered one of my AC ducts had come apart and fixed that too. My attic has never been in better shape. I would definitely recommend Insulation Discounters."

"These guys were the best! I had hired someone to remove the old fiberglass insulation from underneath the house and he didnâ t remove 1/2 of it! John Cameron got extra people to come out and removed the insulation and had to stay a extra day in order to finish the job! Itâ s been 2 weeks and I can definitely tell the difference in the A/C and heating!! I give these guys a 5 plus rating!! Very pleased with the results!"

"TakeAir Houston came to our home to clean our AC vents. After inspection they found we had a mold infestation in all out AC vents and AC unit. Avi gave us a number of photo's to review and told us what it would take to kill the mold and what would be needed to clean the full system once the mold was eliminated. Avi also showed us photo's and videos of our insulation which was contaminated and also missing in quite a few areas of our loft. He then told us what was need to clean out the old insulation, clean the loft and blow 13" of R38 insulation back in. When the guys turned up to do the work they were very respectable of our home and it's contents. They covered everything up and got on with their work. Once everything was completed they showed us the before and after photos and also gave us a video of the loft area showing us the new insulation. All in all they did a wonderful job, quickly, quietly and without any issues whatsoever. They whole team were great and a pleasure to have in our home. I would definitely recommend TakeAir Houston for any mold, cleaning or insulation work you may have at your home"

"Great job, thoroughly cleaned both plenums (in and out), reattached ducts after cleaning (from plenum down and from duct grills up), duccts repositioned in the attic, blower disconnected and taken down for thorough cleaning. All furniture and stuff was vinyl-sheet covered. Vents were repositioned correctly. House smells fresh now. Fast, clean, efficient. Reasonable also, easy to work with. Would not hesitate to recommend this company. Thanks a lot"

Insulation FAQs, answered by experts

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.
