"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"

"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!"

"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."

Insulation questions, answered by experts

Water heater blanket prices range from $20 to $40 on average, though you typically won’t need to spend more than $30 for all the tools and materials required for installation—which include the blanket itself, heavy-duty scissors, and electrical tape. Blankets with higher R-values will also be slightly higher in price.

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

Excluding carpet, strand-woven bamboo provides excellent underfoot heat. Laminate flooring is also good for insulation and preventing cold feet in the winter. Bamboo tends to work better in climates that have more consistent temperatures, while laminate does a better job at insulating floors in homes that experience more extreme temperature changes, such as the deciduous climates of the northeastern U.S.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.
