"Work has been scheduled for early in 2019, but they could not have been more helpful and professional in explaining our options, how our home would get the most out of the panels, and how much we are likely to save. They were explicit about costs and available rebates. We were instructed to apply for a rebate from our local energy supplier and they literally walked us through the time specific rebate procedure. We made some minor changes to their standard contract and they accepted those changes without question. I can only assume their work will be up to these standards when we do the actual installation."

"Galina Woods and Steve worked on Saturday to correct the installation of a dehumidifier and drain pipe system in my crawl space. The system is now working. The exterior drain pipe is finally dripping water. Thanks Galina, you really knew how to correct the problem."

"Very upset. Paid a small fortune for it not to be done correctly. Was told they would return in 6 weeks to reshim. They didn't show and I had to call and schedule an appointment for much later. The appointment was rescheduled by them for a day I was out of town without telling me! Was told when they finally came out that it was not done correctly and they would be back in six weeks to do some more work. No show again. Now waiting for them to call back to reschedule! This has been going on for 8 months. Floor is still sagging. Cracks in walls and ceiling from not having level floors. Ridiculous. I DO NOT recommend them at all!!! (the guys that worked on the house are nice, though)"

CW is proud to be the most trusted and respected weatherization company in the area. They have been the chosen contractor for several Department of Energy, and Utility funded programs for over 6 years. Everyone at CW takes pride in their customer service, cleanliness, and the highest quality, most cost effective improvements available. All employees have the latest certifications. Including BPI, Lead Certified Renovator, First Aid, and others.

"Let's say if you don't go with this company, you'll be severally disappointed. The Carolina Weatherization team, (Matt, Eric, Chris and Brian) are phenomenal! I considered putting in insulation in October to support my energy costs and went through several quotes with other companies prior to selecting this team. I am incredibly happy that I reviewed this quote and chose this team. They let me know they were on the way prior to arrival, took impeccable care of my home by laying down cloth, wearing booties, and doing a bang up cleaning job prior to leaving. They were helpful in repairing a shelving unit and installing a brand new attic door to support all of their work. These gentlemen take pride in their work and it shows with how diligent they are in ensuring that the right steps are taking before, during, and after."

Insulation questions, answered by experts

Freeze-proof faucets can still benefit from insulation, and they will need covers if you live somewhere with extremely cold winter temperatures. These faucets work with a design that keeps excess water in the pipes inside the home to minimize the risk of freezing, plus a downward slope for any water flowing through the pipes to keep moving. But keeping a cover on all faucets, even freeze-proof fixtures, is the best way to avoid frozen and burst pipes.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

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.

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.
