"Mike, Evelyn, and their team were true professionals. 1. The team was on time both for removal and for the installation, which I had chosen to do on different days. 2. They were neat and tidy while doing the job. 3. They were respectful of my property while they were here. 4. They cleaned up at the end of the job so I couldn't even tell they had been here except that I had a fully insulated house at the end of the job. Finally, their pricing was competitive, which was very much appreciated. I cannot say enough good things about them. They were great to work with and they were flexible on scheduling. Highly recommended!"

Eifs Installers FAQs, answered by experts

The entire window replacement process, from the initial consultation to the final installation, typically takes between four and 15 weeks. This timeline accounts for measuring appointments, ordering, and manufacturing. On the day of the job, the physical installation takes about 30 minutes to two hours per window. A full-house replacement can take one to three days to complete. Factors that can extend this timeline include the total number of windows, custom sizes, complex window types, second-story installations, and any necessary repairs to existing window frames or openings.

Most professionals can install a window well in two to three days, depending on the size of the well and the window you want inside it. If you’re just replacing an existing window well, the work is much less intensive, and most experts can get the job done in just one day. Connecting the window well to a drainage system or installing a custom concrete window well will naturally take longer, but even the most complicated installations shouldn’t take more than three days.

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.

They meet local code demands for escape routes, lighten basements, and aid in reducing overall humidity.
