"I would highly recommend John P. Insulation. I got three quotes for my insulation job and they were the most professional during the estimate. They provided pictures of what they were going to do. They fully explained the job and what I should expect. The quote was fast and equal or lass than the others. On the installation day, they arrived when they said they would, covered my floors and completed the work exactly as they said they would. I had them foam seal, blow in insulation, install soffit vents and vent a bathroom fan. You will not be disappointed in the quality."

"Coleman did a wonderful job on our remodel. They did spray foam on the roof of the entire house and installed bats to insulate the walls of our demo'd side. They also had to remove old bats in half of the attic. They were very clean in the disposal of the old insulation and clean up of the overall job when they were done. Communication was great from the start...Shant was very communicative from the initial estimate through to the completion of the job. They were very competitively priced I'd recommend to anyone looking for an insulation contractor."

Insulation questions, answered by experts

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.

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.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.

An insulated garage door is a great long-term investment if it’s within your budget. They save energy and give the door year-round usability. In other words, the door pays for itself after a few nasty winters. Most modern garage doors already have a fair amount of insulation, so look into those options if you don’t feel comfortable splurging.
