"Mike (owner) and Kyle were very knowledgeable and hard working. In two days, they modified the venting in my attic and bathroom so it would work correctly and sprayed 13" of insulation in my attic. They were efficient, friendly, and professional. They left my house completely cleaned and explained everything that they had done. It was refreshing to work with a contractor that obviously has his customer's best interests at the top of his priority list. I would highly recommend Mike, Kyle and Bill Busters for any consulting and installation on insulating products."

"This company cares. They put people above profit. I was in a bad situation, after a nasty winter my roof seemed to be disintegrating before my eyes. It went really fast. Then Daryl stepped up to help me out of a difficult situation. Within hours they expedited the crew, and Walter and Lauren ordered materials and made my roof a priority. Now with three days of rain coming I know my house is protected and it looks gorgeous."

"Chris and his crew from Deluxe Seamless Gutters were amazing; they were always on time. Chris was also able to fit me into his schedule and finished a week earlier than originally scheduled. We had all new gutters/fascia/soffit done and it looks fantastic. They did quality work and always cleaned up when the day was done. The quote was exactly what I paid and Chris explained the process the entire way. I could not recommend Chris and his crew enough and will be definitely using them for other work in the future."

"It was a pleasure dealing with Mincin and the final result made it worth the expenditure. They did cellulose attic insulation as well as dense packing the floor of an addition from its crawl space. Quite a difference!"

"Down to earth and tells you the truth about what you are getting. The other installers were not like Matthew Harr. I put a star by his name after I talked to him. I knew I would be calling him back. Give him a call for your next insulation project. You will not regret it! I would definitely call him again."

Insulation questions, answered by experts

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

While fiberglass is dangerous to work with, it’s a perfectly safe material once it’s installed. If you’re tackling the installation yourself, make sure you take the proper safety precautions and wear the right gear to avoid skin and eye irritation and lung complications. Working with a professional insulation company can mitigate these risks.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.
