"Exactly as the same as the first time I air sealed my attic in my previous house. Last year when we decided to sell our house I was inspecting my house as I would have if I was purchasing it. I noticed a small (1/4") gap between the master bathroom vent fan grill and the ceiling. I could not adjust it. Upon further inspection I realize it was because the foam that was installed when my attic was air sealed had expanded creating the 1/4" gap. I had that work done two years prior by Houle Insulation. I contacted Arne and inquired if he had any suggestions. His only suggestion was that he would correct the problem. Two days later he had two workers in my attic correcting the issue. Just like the first time, they were prompt and cleaned up after the work. I offered to pay, he would not have it. He said he should have noticed when the job was originally completed two years prior. There was no discussion or haggling, he simply said he would correct it. As impressed as I was with the lower energy bill, I was more impressed with how he and his team comported themselves. Also my house was more comfortable because the temperature was more uniform within my house. This year when we moved into our new house, built in 1992, the first thing I did was call Arne to air seal the attic. My choice of whom to hire for air sealing my attic was a no brainer, Houle Insulation. They also performed a blower door test. They also sent in all the information required for me to receive an energy rebate from my utility company. The best recommendation I can make is that when I decided to air seal our new home the first person I called was Arne. He made a wise decision to correct what needed with correcting without any questions. He did what should have been done, and therefore he got my repeat business and I was happy to give my business to him!"

"Very well, these guys are great, they seal everything right and load tons of insulation. My house is now at a R60. And this was not cheap, however I do not expect heating costs to go down for many years to come unless we all go solar."

"We needed to replace the siding on our home, had four companies come to our house (three of which were initially found through Angi), and are glad that we used Hoffman Weber to do the job. Their sales associate (Al Lien) was knowledgeable and helpful, but no pressure, which I personally appreciate very much. They had a range of options, and in the end we chose to use HardiPlank which was less expensive than LP at the time of our project. The Hoffman Weber price was very competitive (and significantly lower than the high-pressure company that came out). The installation went well--the crew was hard working and pleasant, and communication with the project manager (Pete) was easy (the installation was done in February, so, weather affected the days of installation). The finished project looks great."

"It took a day and a half to complete this project.
Everything went smoothly from start to finish. This was a very difficult job due to the limited space in the attic.
Sam is very efficient and confidant in his work & fair in his pricing.
I would highly recommend Sharpe Construction and plan to use them again in future projects."

"Mark and his crew showed up on time (Friday morning) to perform the work.  They initially laid down pads and painters sheets since blowing in cellulose insulation can get quite dusty/messy.  They performed the work exactly as described in the bid.  Insulating my attic to R60 (up from what it was of R12-15) and filled in all the joists, etc.  They even build a wooden platform around an air handler in the attic so it can still be maintained with ease.  One of Mark's co-worker spent most of the time in the basement fixing the frozen pipe issue.  He applied insulation and sealant in a crawl space near the main water line and reseated an air vent behind the wall, while applying more insulation.  He even went to a local hardware store and procured a vent to cover up a hole in the wall we wanted to leave exposed so warm air can flow through (didn't even ask or think to charge me for the vent).  The job lasted about 6 hours (which was exactly what Mark quoted).  They cleaned up with a shop vac so the house looked very clean when they left.
All in all, was very pleased with the professionalism, knowledge and service provided by Mark and his crew.  I proudly displayed a sign in my front yard advertising his services to others and would recommend him to family/friends.

Insulation questions, answered by experts

Most heat in a garage is lost through air leaks in windows, doors, and walls. This is especially true if the walls are uninsulated, which is common in garages. Consider insulating your garage before installing a garage heater to ensure the heat it generates isn’t wasted, making it less efficient.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.
