"From initial contact with their sales department we've had a great experience, Corey did an excellent job of taking pictures and showing the problems in our attic. Their level of communication from emails to phone calls was precisely correct by contacting me when needed and not too much with pictures detailing each solution and its associated cost. On the first work day their crew called ahead of time, arrived promptly and came prepared with masks, plastic sheeting, full body outfits and cloth covering for the stairs. In just over 6 hours they had cleaned up the entire attic removing bad sub-floor and other insulation, laid out the foundation for building a large deck space and placed part of the first layer of materials down. They also sealed the attic door along with some of the air vents and ceiling fans. They completed insulating my front porch overhang and cleaned up all of their mess very well. Painters tape was used on corners where they we’re most likely to bump into it for protection and plastic sheeting was setup precisely where needed to keep dust off of our hallway things next to the attic entrance. Overall it was a great first day and they even spotted an issue from a previous vendor who failed to properly connect some of their duct work together (which was the original cause of my daughter’s room temperature being so hard to control the temperature and not easy to spot). The only complaint I have is that while I fully expected the need to finish our attic sub-floor, remaining layers of TruSoftTM Cellulose on the main floor and encapsulate the duct lines with Polyurethane Spray Foam all before finishing with blown-in insulation, they left a key piece incomplete. When leaving they left the duct work leading from our main trunk line to my daughter’s room off. This left a hole in the main trunk line reducing heat in all upstairs rooms but most important is that nothing was connected to my daughter’s room. So around 6:00am she woke up coughing as we noticed the upstairs was around 56 degrees. Overall a simple heads up would have solved everything as we have space heaters, however I did not look into the attic when they left so that’s my fault for not knowing a key piece of the duct line was missing. Based on the overall work complete I would still very much recommend them as Robert (onsite team lead) was very good at communicating and the crew we’re all quite friendly. Their work will last for the lifetime of my house and has already added value to the sale price. In the end they made a really nice attic deck leaving me with plenty of useable storage space. While this is not the cheapest company, the quality and knowledge that I never need to worry about my attic again is certainly worth it."

"Insulating a crawl space is incredibly expensive (especially for a space that hardly anybody ever sees or goes into), but they did a good job and it has helped in keeping the pipes warmer in winter and reducing damp feeling inside the house."

"The team arrived slightly early to be well prepared to start the job on time. As they began they laid down protective barriers to keep the home clean. While in the attic they blew in the insulation with an even consistent barrier, ensuring that all locations with infrastructure were well covered. As they wrapped up the job, they cleaned behind them as they closed up the attic, removed the floor coverings and were on their way. The only way I can tell they were here is that the heat runs less in the winter and the air conditioning runs less in the summer. I would recommend this process and this team to anyone who owns a home and has not insulated their attic."

"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!

FAQs for insulation service projects in Winchester, VA

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.
