"As you know finding companies to work on your private home, is very frustrating. I was impressed by Oliver the foreman from estimate to completion of the job. The honesty and integrity were the part of the job to make me confident that I had made a score in finding a professional company.

"We are completely delighted. Everything went perfectly. Danny, our sales representative, was great at explaining options, and was always available for questions. The expert installers, Andreas and Dmitri, were fun to work with, responsive to our requests, and even installed our new doorbell. I look forward to working with this excellent company again for new windows."

Egress Windows FAQs, answered by experts

An egress window is similar to a regular window. However, this type of window opens fully to allow people to escape the home or rescue personnel to enter the home if an emergency occurs. Egress windows are required in all finished basements before they can be considered a living space.

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.

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.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

Yes, egress windows are grandfathered. However, this comes with some specifications. If you are remodeling a basement or adding a sleeping area, you’ll need to update the egress windows to be up to proper code. But, if you’re leaving your home as is, you do not have to adhere to these requirements.
