"I called 5 Insulation companies for estimates in Oct.2025, when we were having other work done to our home & discovered we had No insulation between the studs. USA 🇺🇸 Insulation was the most expensive but they were the most thorough during the sales process, as far as explaining how everything was to be done & showed me photos. They were the ONLY company that offered the blown in expansion Insulation. Which is what made the job a little more costly, but they used the best product because it doesn't settle over time, which to me made it worth it. They came on Dec.15th which was a VERY cold day, with a 4 man crew,each with a specialized task, (Foreman, siding removal, hole driller, foam insertion). They were very professional, answered all my questions, cleaned up my property when done & did a heat camera procedure that showed me how the walls were cold before hand & were already warming by end of job. I highly recommend this company to anyone needing to have this done."

They provided a thorough assessment of my home’s insulation needs and offered clear, honest recommendations without any pressure. Their expertise in spray foam insulation was particularly impressive, ensuring that every nook and cranny was properly sealed."

"Salesman was very professional. Showed up in a vehicle worth the name on the side and in a uniform. Made a video of the bad area of our gutters and explained in detail what problems this would cause and had a very good presentation about the company and product."

"They did an excellent job the opening to the crawl space had to expanded to allow entry of a man, and Saunders was able to do this. They installed a bathroom fan , so that the fan could be vented to the outdoors instead of into the Attic. Saunders personnel were able to tell me what they saw while down in the crawl space, which included other issues that I will need to resolve in the future, but which I'm glad to be made aware of. Per my brother who is an engineer, Saunders did an excellent job of both lining and insulating the crawl space and insulating the attic. My brother is picky so I can recommend Saunders installation specialist."

Insulation questions, answered by experts

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.

Yes, you can use too much bubble wrap. If you overdo it with the wrapping, it can strain the top of your box and break open the taped seal, risking the chance that the contents of the box could fall out or break. Use enough wrapping to fully cover your item without compromising the security of your box.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.
