"Mickey and his crew were incredible. When Mickey came out to meet with my husband and I, he went over every step of the installation process including the materials that would be used. On install day, his crew arrived on time and got to work quickly. Our roof was completed day one, and downspouts and gutters the next morning. Clean up was very thorough, they went over our yard quite a few times. I highly recommend M Mac Exteriors. We had received a few estimates and Mickey stood out against the rest. He’s knowledgeable, priced fair and was just an all around pleasure to work with."

"I needed a new roof to satisfy the Insurance company (my existing roof was 28 years old). Called Home Run Roofing at 5pm on Monday, scheduled the rep for the next morning. Thorough inspection of all roofing components, discussed price, color etc. They happened to have a cancellation on Friday (today). The work crew arrived and quickly dispatched the old roof, had the barriers in place, ridge vent installed shingles placed and total cleanup of the site by just after 2pm. Amazing! This was a great experience with Home Run roofing from start to finish. I will be working with them again to replace my windows for sure! The roof is beautiful!"

Eifs Installers FAQs, answered by experts

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.

There are a range of egress window types available, including:

  • Single-hung: $100–$400

  • Double-hung: $250–$500

  • Horizontal/sliding: $150–$800

  • Casement: $200–$500

  • In-swing: $350–$700

When choosing a type of egress window, consider how you’d like to open it. For example, double-hung egress windows open from top to bottom and let plenty of fresh air in, whereas sliding windows slide open for easy access.  

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

The proper way to install a window well is to measure the window, dig a hole deeper and wider than the window, place a drainage tube and cap, anchor the well to the foundation, caulk the seam, and backfill the hole. The job requires tools such as a hammer drill and auger and some heavy digging. Proper placement and window well installation are critical to preventing water from leaking into the window.

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.
