"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."

"Home Services - VA installed the a/c line to the dog house within three hours (Home Services - VA had all the tools needed to perform the installation).
Because the distance between the garage and the out building turned out to be longer than 100 feet, Home Services - VA found a way to attach an additional segment of metal wire to extend the length, allowing the zip line to reach the anchor attached to the out building.
We no longer fear reprisals from the next door neighbor for the dog digging under their fence and the dog has access to the a/c during all hours of the day. Because the a/c line is attached to the home heating and air line, the dog house will also have heat in the winter."

"My house has 4 large windows across the back of the dining area that were weathered and damaged and in need of replacement. Owing to the expense, I'd put the job off for about 2 years. I saw the Angie's List big deal for WDW to install 5 windows for $1995 and took the plunge. Bruce showed up within days to explain the deal, take some measurements and work out the details of the job. While my priority was to replace the 4 damaged windows and hadn't thought about a fifth, Bruce convinced me that I might as well replace another to take full advantage of the deal; I decided to replace a kitchen window that had some problems. I paid an additional fee for grids on the kitchen window and to have the interior trim replaced after the job.
David and Sean showed up about an hour later than agreed on the day of the job, but went right to work. They had the four windows out in about an hour and the new ones in shortly thereafter. They worked quickly and well together, and cleaned up the debris as they worked. Same with the kitchen window. They had to make a quick trip to Home Depot for the trim, but returned quickly and cut and installed the trim. David insulated the air gaps around the windows and caulked them inside and out. The entire job took a little over five hours. The final product looks great.

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
