"We had a horrendous situation with a basement floor installation that went wrong leaving our house full of fumes, and a week later we discovered our basement was contaminated by asbestos in the process.  When we called Bill and Contractors Unlimited, they were extremely responsive.  Although other companies gave us bids, Bill was able to work his schedule to fit us in weeks sooner than the others.  Although the cost was a bit more, that saved us money because we were displaced and could not even go into our house because of the fumes.  CU set up negative air machines to replace the air, they followed asbestos abatement laws, they cleaned every item that could be salvaged in our house.  They even saved more than we thought which really reduced our overall expense.  Bill and his team were extremely professional, friendly, helpful, and really went out of their way to ease our stress from this situation.  At the end of their process, Bill arranged for a air quality inspection which we happily passed - able to return home.  I would gladly recommend Contractors Unlimited for asbestos abatement.  I just wish we had called them before the floor guys  created such a disaster.  Thank you Bill!

"Fantastic work!  Fast, easy and professional.  These guys know what they are doing.  We also used Accurate Insulation last year when we bought the house, and they provided whole-house insulation to add to the original 1965 builder insulation.  They were able to provide advice on what would be too much insulation and could cause poor indoor air quality.  Would use them again anytime.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

Yes! Outdoor faucet covers work by enclosing the faucet with a thick, insulating material that will keep the faucet warmer than outdoor temperatures. They need to be sealed tightly against the house to work properly, though, so be sure to tighten the rubber strap or drawstring on the insulation cover to best protect your faucets.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.
