Customers say: Quick response

"Dave offered fair pricing, arrived on time, did a fantastic job, and my one request was to be careful of the ceilings because they have irreplaceable texturing no one knows how do do anymore. He excelled at caring for my property, and the results have been astonishing, my AC runs less than 50% of the time it used to, and doesn't kick on until mid-afternoon even on 90 plus degree days. Adding insulation by Dave was one of the best decisions we've ever made!"

"Gio did a great job insulating pipes in our basement that kept freezing when the temperature drops below freezing. He did a great job completing the job and cleaning up the mess afterwards. I would definitely recommend Gio on all insulating work."

Insulation questions, answered by experts

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.

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.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.

Yes, you can install insulation behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you’re looking to add insulation, it’s better to hire a professional, as you’ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.
