"It went pretty well. They tool longer than I thought, and they used a sealant (gray) that didn't match the color of our house (white) or the concrete stoop. We were planning on painting it anyway, so in the end it's not a big deal. We like Real Seal and would use them again."

"Quick and complete estimate provided for egress window replacement. Very helpful service in understanding what was needed and in scheduling the work. The Real Seal did excellent work and completed my windows in one day. I would highly recommend them for foundation/egress window work."

"Trying to execute a major outdoor renovation project during a time of global supply chain disruptions poses many challenges. Happy to report that Mal and PHI navigated that rocky path very well. Mal kept us informed of the many changes coming from the supplier as far as colors and delivery. It was a long process...8 months between signing the contract and having the work completed. In the end we are very happy with the product and the quality of the work. A major windstorm hit the area the day after the work was completed and put the installation to the test. Everything held up perfectly...no loose bits flapping on the house or flying around the yard. In researching this project ahead of time, we had spoken with many friends who've had their siding replaced and none of them were especially happy with their contractor. We had the best experience with Mal and PHI. Highly recommended."

"First off, everyone we've dealt with has been professional, friendly, and courteous. We liked the reviews we saw in Angie's List and Murphy's installed a new sliding door for us in Nov 2014. One of our requests was it be "lightweight" and easy to slide. Well, it didn't seem that way when it was installed, but we were told to give it some time to loosen up. Nope. Still heavy and hard to open and close... 3+ years later. Next problem was the screen door with it. In Spring 2015 (when we needed it, since the door was installed in the winter), the screen door continuously came off its track. Don came out to fix it ("right") and it almost lasted until the end of the season. I spoke with Jimmy Murphy who runs the place... again, super nice and super friendly... but when I reached him to help... lots of delays, promises, etc. I kept putting it back on the track myself for short-term fixes. I called/texted in the Fall 2017 to have it fixed or replaced... no response. Called/Texted again in Spring 2018 and was told someone would be out to take care of it. No one. Another call and text promising to be there "next Tuesday." Nothin. I've had enough. Well meaning group, but lacks follow-through and, apparently, the ability to keep customers happy/satisfied. Hard to imagine that 20 minutes of their time and/or possibly $10-50 in parts will cost them my future business and possibly the loss of others' business (after reading this). Won't use again...."

"Overall it went well. The only thing I would say is that initially they wanted to use a part from an entire faucet combo (cost about $168) when eventually the part could be purchased seperately for about $40.  But I asked questions and they accommodated by going pick up the part at home depot.  That was very helpful as we were able to get all the work done that day.  Jennifer was great to work with....very responsive and timely follow up.

Egress Windows FAQs, answered by experts

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.

DIY is possible for experienced individuals. Professional installation ensures compliance with building codes and proper sealing.

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.

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.
