"Jason and his team did a great job insulating our renovationâ and for a fair price. Now our basement is cozier than our main floor, so we are going to have to call them back to insulate our attic!"

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

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

Yes, products made from renewable resources and with reduced chemical impacts.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

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.

The cost to rent an insulation vacuum ranges between $250 and $350 per day. The price will increase if you choose to rent for additional days, but you may get a discounted daily rate if you rent it for a whole week, which could cost up to $1,000. Once you've removed the insulation and are ready to replace it, the cost to rent a blown-in insulation machine ranges between $100 and $500.
