"We hired Mark and his team to install new spray foam insulation in our attic to meet the higher demands and code compliance required that you can not get with old style bat insulation. The spray foam sealed all of the leaks we had and made our home less drafty. They also put in new solar attic fans to keep the heat down so our HVAC did not have to work so hard. Great Job Koala!"

"I have only glowing things to say about our experience using Home Genius Exteriors. From the thorough initial estimate and comprehensive inspection of the worksite and what the job would entail to the final bit of blown-in insulation, our multi-team project was completed to our satisfaction in a timely and professional manner. In the course of four days, we had a new roof, new trim, new gutters, and new insulation. Each part of the project required a different team. Each crew finished their task within the projected timeframe. Home Genius coordinated everything, including ordering and delivering the materials and arranging for the delivery and removal of the dumpster. Thanks to our Project Coordinator Ivan, every step in the process went smoothly. He arranged for workers to be at our home on consecutive days: we did not have any time in between steps waiting for availability of the next team. Ivan kept us informed of progress at every step of the way."

"I purchased a multifamily house with 2 stories. The 2nd floor had 1 inch original hardwood from 1920 that laid on the floor joists so you could hear every footstep downstairs and my tenants almost moved out. I hired Cesar to take on a tedious and technical ceiling soundproofing technique for the apartment using RSCI rubber clips, hat channels, insulation, and making the 1st floor airtight. I was so impressed with how he was able to juggle handling my tenant for 2 weeks, compensating for delayed shipping by driving 3 hours to New York and picking up the materials himself to make sure we meet the deadline, redoing 1 entire room at his loss and not charging me for it because the original technique we tried did not work, and listening and working with me to make sure we didn't miss any details that would cause sound transfer (and this was impressive because I am very detail oriented). My tenants moved in and were very impressed by the finished looked of the new ceilings and crown molding. We saw a sound improvement of about 15 STC in both airborne and impact noise. It cut down sound transfer by 2/3 in the 1st floor apartment. I will be adding rubber underlayment upstairs underneath the new flooring to completely block out the rest of the impact noise that transfers from the floor above to the walls downstairs that support it! I'll be calling Cesar and his crew again."

Insulation FAQs, answered by experts

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

The heat loss through a poorly insulated attic when you’re running your furnace or heat pump during cold weather can be as high as 25%. This means you could see significantly higher energy costs to make up for this heat loss. The cost of adding insulation to the attic may eventually pay for itself through lower energy bills. If you decide to add a radiant barrier too, the radiant barrier cost may also pay for itself over time.

Whether plaster walls should be insulated depends on whether the walls are at particular risk of moisture problems. In many cases, you can insulate plaster walls, while in others, it's a poor decision because of the lack of a vapor barrier. Choose a reputable insulation contractor to help you decide if and how to proceed to increase your home's energy efficiency.
