"American Home Renewal did an excellent job. They were incredibly responsive and helpful, especially when dealing with the special circumstances and constraints of retrofitting windows within the guidelines of an HOA. Mark who ran my initial estimate and supported the project through the end of the contract creation and signing was always available to answer questions and willing to help out when I needed support with my HOA. The installation team did a wonderful job, they were prompt, professional, and courteous. And when I discovered several tears in one of the screens about a month after the project, AHR sent someone right out to fix it. I am extremely happy with my new windows - the house is much warmer and quieter now, and I've already recommended the company to several of my neighbors."

"Joel came and did an estimate for us today. I found him to be extremely knowledgeable and delightfully honest. I previously had another company come out and give me an estimate. That company wanted to charge ~$4,000 to remove existing attic insulation and add R38. They also wanted to charge ~$3,000 to add wall insulation. Joel inspected my attic and told me the insulation was actually R30 already and looked to be in good condition. He didn't recommend adding any more. Joel also inspected the walls and it turns out it already had insulation in them. THANK YOU Joel for being so honest and saving us a ton of money! I would highly recommend him (and Bay Valley Insulation) to everyone I know and to others on Yelp. Also, he did write us a very reasonable estimate to boost our insulation to R48 if we wanted to go the extra mile."

"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."

Eifs Installers FAQs, answered by experts

Egress windows are typically required for basements with habitable space or living quarters. Not all basements or lower levels require egress windows. However, egress windows are required in homes with living spaces such as bedrooms and living rooms in a basement. The International Residential Code and International Building Code require sleeping rooms to have a specific size egress window. Check your local building codes to confirm the requirements in your area.

Yes, egress windows must meet local building codes for size and accessibility. Professional installers ensure compliance.

Adding windows to a house is expensive. Budget roughly $5,800 to add a single window, and double or triple that to add two or three. In some cases, adding a single window can exceed $20,000, depending on the type of exterior wall, the size of the window, the type of window, local permit costs, and other factors.

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

Expect excavation below grade, creating a well for access, weatherproofing, and thorough inspections during setup.
