"This could not have gone any smoother. Despite having to re-schedule the original, 1st quoting appointment, Darren was here the very next day. I had a quote by the end of that 2nd day/appointment, was scheduled the next day for the following Monday and the 2-person team was in and out within 90 minutes. My kids didn't even wake up(granted, they could sleep thru the emergency siren!) but wow. My attic/crawl space is now fully insulated! All this while we are adjusting to our new normal of social distancing and heightened sanitary measures. I would use AFI again and would recommend them based on this experience."

"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."

"The team was on time and very friendly. They explained what they were going to do and got right to work. They laid out materials to cover our belongings in the bedroom as well as the carpet. After they had installed the insulation they patched the holes really well. I won't have to do any extra work! They even vacuumed after they were done which was really appreciated and a sign they care about the quality of the work they complete. I will hire them again in the future to complete more insulation of our attached garage. I would also recommend them to friends and family!"

"Had a water leaking through my roof from Ice dams and damage on whole wall on the west side of my living room.  They had to replace all dry wall, insulation and match the half of my ceiling to the other half that was not damaged.  Also replace a huge 1960 window with 3 new energy  windows.   Great work you would never know that the half of the room had been redone match all the paint and knock down on the ceiling to a tee.  Very knowledgeable, professional and kept me updated on all the process that was going on."

Insulation questions, answered by experts

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

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.

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

Yes, insulating your pipes can reduce plumbing noises because it dampens vibrations and reduces the transmission of sound, making your home a quieter place. So if you've ever been annoyed by the sounds of water rushing through your pipes or the clanging noises when someone turns on the faucet, insulation can help.
