"Had the whole house insulated in 2016. Just found out that there is now mold in the attic. Have had three different contractors come to look at it and ALL have said the reason is because when the insulation was blown into the attic they did not take the time to rake it away from the soffits. Now I'm faced with a major repair bill of $3000 to eliminate the mold. Plus, to make matters worse, my utility bill did not go down very much after having this done. Only thing I can say is that the house is more comfortable. So beware if you use this company and make sure they install the insulation into your attic correctly!"

"My wife and I attended a presentation by James Manfield, the owner of GreenForce.  We were impressed with company product and Jame's punctuality, professionalism and honesty.  We decided to hire his company to add insulation to attic of my in-laws house.  The installers came on time and over 9 hours managed to complete 95% of the job.  The installers were polite, professional and clean.  The subsequent installers came next day and completed the job.  We are very pleased with James and the service provided by his company. As FYI, we had similar radiant barrier installed by another company in our own house in 2012 and we were pleased with the reduction in heating and cooling cost."

"I contacted RoofWise Roofing Inc in July 2010 to get an estimate on replacing the roof of my ranch house.  An estimator came out and walked over the roof and then discussed replacing it with me.  We also discussed replacing a damaged gutter in the front, repairing a sagging back gutter which did not drain properly, and putting a rain barrel in.  He suggested clips to hold the gutter up, but said it might not work.  He answered my questions and explained different components of the roofing system thoroughly.  He was pleasant, helpful and seemed very knowledgeable.  He explained that a likely future consequence of getting a ridge vent would be that I might need more insulation.  This was helpful and made me feel he cared about the overall functioning of the house.  He recommended chimney caps for the chimney and new soil stack boots.  He offered to get roofing shingle samples and put them on the roof to help me decide on a color.  He also showed me some sample shingles. 

I received a bid within a week.  It was very professionally done and the price was reasonable compared to my other two bids.  A helpful pre-roofing checklist was included.  RoofWise offered a 5 year warranty on parts and labor, which was very good.  My decision was difficult because all of the companies I interviewed sounded good.  I give RoofWise an A in a relevant categories.  My one suggestion is that they work on developing a more consistent and professional telephone response, when someone calls the office."

"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 FAQs, answered by experts

Bathroom wall insulation not only keeps the area temperate, but it also reduces instances of mold, mildew, and rot. Bathrooms, after all, are havens for moisture. With this in mind, it’s absolutely worth it to insulate bathroom walls since it saves money in the long run. You won’t have to hire a pricey mold remediation service down the line. Also, insulation decreases outdoor noise and lowers energy costs.

Although spray foam insulation typically has a higher price point than traditional insulation, the benefits often justify the investment. It offers superior sealing properties, which can lead to significant energy bill savings. Spray foam also provides excellent moisture resistance and soundproofing. Other advantages include improved indoor air quality by minimizing allergens, a long lifespan of 80 to 100 years, added structural strength to the home, and a straightforward installation process.

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn’t justify the harm and danger it poses.

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. 

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.
