"I was impressed with Aaron, the owner. He thoroughly explained what he was going to do, and took before and after photos of the job. I have noticed a big difference in the comfort level of my home. The HVAC unit rarely kicks on, as the insulation is holding the temp much better."

"I'm extremely impressed with Luis and Icon Insulation. After moving into a 115 year old house about 5 months ago, and having a lot of contractors doing various jobs, Luis was a breath of fresh air! I had him Insulate my attic, and then I had him back again to insulate under our floor. I would highly recommend Icon Insulation to anyone I know. They are very responsive and answered all my questions before our appointment, punctual, professional, and have a great work ethic. (Something hard to find these days.) Thank you for your great work!"

"We have a 1970's and we decided to have an energy audit by Landmark Construction. It was clear that our house have some energy issues and was in need of a any type of energy overhaul.  The report that was prepared for us by Charlie and his office staff, was comprehensive, clear to understand and revealed that the ducts at the attic  was not sized appropriately. In addition to that, the furnace/AC in the smaller unit was old (and original) and had to be replaced. The recommendations that Charlie told us, included a new furnace/AC, new tankless water system, hot water pipe insulation, building sealing, the insulation and new ducting throughout the house. This was the best investment we ever made.  I could not believe the difference in our utilities bill.  Charlie and his team were great,  professional and experienced. I wish we did these 15 years ago!!

"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

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

You can insulate an existing garage door. But while it’s a cost-effective option upfront, it may not perform as well as a garage door that comes with insulation. If you live in a colder climate—or if you plan on working in your garage and need a new door—you should purchase one with existing insulation for better efficiency. 

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.
