"Great experience getting windows installed by American Home Renewal. First contact was 6 months ago. I slept on it for a few months and got some other quotes. Chris was friendly as a sales man, Gave me a competitive price and some pointers on fiberglass vs vinyl. I went with Vinyl. Alex was the installer and was very detailed in explaining the install process. He explained everything in detail to me and showed me tips on how to do a proper install. We did a mix of new construction and retrofit. we added window casings and he was very thorough and asked multiple questions on how I wanted the casings to look. only hiccup was one of the windows was ordered wrong. we couldn't determine where the mixup occurred but they immediately took full ownership and reordered me a new window to the specs I wanted. I would highly recommend."

"The Good:
Pretty good experience all around.  The crew was a bit late, but they did call well in advance and let me know.    No problems there.
The 2 man crew was polite and did clean up the job site when they were done.  The insulation was installed properly for the most part. (see below)
The Bad:
My only real complaint was that they buried 4 attic vents in the insulation. I  was able to easily remove the pieces that were blocking the vents. I didn't specially say to NOT block the vents, but I would assume an insulation company would know to not do this.  Easy fix, so I'm not too upset about it.
Overall:
Very good price, availability was quick, and the installers were easy to work with and didn't leave a mess.
I would definitely use them again, but would suggest if you do, to make sure you mark and/or double check your attic vents before they leave.  My room didn't have drywall put in yet, so this was easy for me to fix.  Alternatively, install the vent protector metal or plastic "ducts" first.

"I hired Atticare to remove and install new insulation. Ricardo was awesome and responsive to my questions. They weren’t the least expensive but were reasonable. Elmer and his crew did the job. I have to say if I could give Elmar and his crew 10 out of 5 stars I would. I would totally recommend them."

"We chose ThermaCore Insulation for our new construction project, and the experience has been great so far. The team was professional, knowledgeable, and easy to work with throughout the process. They showed up on time, communicated clearly, and completed the insulation installation with attention to detail. We?re very happy with the service and would highly recommend ThermaCore Insulation."

"New Gen Exteriors removed the old vynl siding on my house and then installed new Hardie board siding with foam insulation underneath. Serg the owner was very polite, straight forward and easy to deal with, as were his men. They cleaned up each night and were also quiet when they worked, no loud radios etc. I plan on using Serg in the near future, because he does very professional work."

"Dimitri provided siding replacement that was 30 yr old T111 that was warped due to sun exposure. He recommended hardey board for durability. The pictures I enclosed show tear off to finished install. Dimitri was very conscious about doing a good job and cleaned up after. I recommend using Dimitri if you need any exterior work."

Eifs Installers FAQs, answered by experts

Yes, you absolutely need a permit to add a window to your house. Your contractor can likely obtain this permit on your behalf. Ask about this when getting quotes from multiple window contractors.

Because egress windows are meant for emergency exiting and entering, they need to be an accessible size. The smallest an egress window is allowed to be is 15 inches in width and height, with an opening of around 4 square feet.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

There are a few ways to save money on egress window installation. First, choosing pre-fabricated windows instead of custom windows can help dramatically reduce the overall cost. In addition, skipping window extras, like customized frames or window film, can help save money on the price tag without sacrificing the window itself. You should also shop around to multiple window installers to find the best installation deal without sacrificing the quality of the window.
