"Abraham and his team, Will and Josh, did a great job of removing old insulation, sealing air leaks and adding new insulation to the attic in my 46 year old home. The old insulation was blocking air flow through the attic and this needed to be addressed, which they did. They were very professional and hard-working. Communication was excellent and everything was well explained and the process photographed. We are glad we hired Abraham for this project!"

"We have an Older home so some of the construction was differant but Shannon was able to solve any problems and did a great job of Insulating our side walls and the attic. We will now have a warm and cozy home. We can already feel the difference. We are waiting for the first utility bill after this was done to see how much our heating bill goes down. Would highly recommend S and K for insulation services. Dennis J"

"Jeff Smith is based at the Waterloo office. He was very good at customer service & responded to my emails in a reasonable time given this is probably a busy time of the year (November) for them. I am having additional blow in insulation behind a knee wall & in the attic to bring me up to code. The work has not been completed yet. I am waiting for an energy audit. That is why I can only rate the company as a 3."

"Abraham and his crew are amazing! He came highly recommended from my best friend that her home insulated. Fantastic communication, easy to work with, even when we had extra questions and concerns due to bad service people we had previously worked with. He eased our minds, he's professional and his crew was polite and cleaned up everything at the end of insulating our 3 attics!"

Insulation questions, answered by experts

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

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.
