Get matched with top egress window installers in your area

"From the very beginning, this company was prompt, knowledgeable, and professional. Despite over 3 inches of rainfall in my yard just days before the installation, I braced myself for how much the project might damage my lawn. To my surprise, there wasn't a single rut left behind! The site was spotless, and they took great care in cleaning up everything, showing full respect for both my yard and my home. The work they did was outstanding, and I highly recommend them to anyone."

"*** Update. After talking with Pat at Four Seasons, they have to decided to make things right. Our windows are now going to be replaced with windows with grids. The gutters have been fixed. Everything has been fixed. Advised Pat of the major lack of communication from the sales team. Buyer beware!!! This is the second time that I have worked with Four Seasons, and will probably be the last. I called to have new fascia, soffit, and gutters installed. I told the salesman that the fascia bored was rotting in several places. He also told me I should order windows as they are having a big sale because of covid, so I did. I was told that the soffit, fascia, gutters would be done in 2 weeks. They showed on the 4th week, and the only reason they showed up then is because my constant asking when they would be out. The installed the fascia over the rotten parts. I called before they were done and the owner came out and said that would be an extra charge but we will replace the parts that are not done. They left the stuff they already cover up. When the guy came out to measure for the windows we were asked if we wanted grids or not. I told him we wanted grids. When the widows showed up they did not have the grids. My salesman said he could fix it, but it would cost $191 per window to fix it. Also, after the gutters got installed, my wife heard the installer say "wont be the first job for me to get called back to fix a job." One of the downspouts is installed incorrectly. I noticed it the next day. Here almost 2 weeks later and it is not fixed. Be very careful when ordering through them and make sure you double check the work before they leave. The communication between costumer and sales is not lacking. W I wished we had the other sales person we used before. He is no longer with the company."

"The sales person was excellent, honest, friendly, professional, not pushy, took time to explain things and answer questions and was able to get some one out to take measurements the next morning, who was also very friendly and professional."

"I am so happy with the work that Cornerstone did on our windows. After dealing with several lengthy, high-pressure sales pitches from other companies, Derrick from Cornerstone was a breath of fresh air. He came out in May and was able to quickly give me multiple options for the best products for my house. I appreciated that he did not try to upsell me, while still showing me high-quality products to choose from. The windows came in early July, but I had to postpone the installation until 7/27, and Cornerstone was so flexible about the schedule. The crew showed up promptly and worked efficiently without cutting corners, they were friendly, and they did a great job cleaning up after. We noticed an immediate difference in the temperature and comfort of our home as soon as they were done. I was also impressed that one of the owners called me the following Monday to make sure we were satisfied. We received stellar customer service, high quality work, and an excellent finished product from Cornerstone. I would highly recommend them for any window replacement project!"

"Had several problems with them residing my house. First of all, the dumpster was supposed to be at my house early in the morning on the day that they started. It did not show up until 6 pm that evening so the old siding was on my grass all day and killed some of it. After they were done, I checked everything and found they messed up my electrical, did not hook the exhaust hose back up when they installed a new vent. The project manager was not any help, so I had to call the owner. Eventually they got an electrician out to fix everything and I hooked the exhaust hose up myself and now everything is good but the fact that they said they were done and left things a mess if what bothered me. It took a couple weeks to fix, and it should have been done in 4 days. Most people probably don't check everything like I did so who knows if they did this to other homeowners."

"They have a lifetime warranty which is great. They're awesome."

"Perfect...he did a great job and fast"

"ACE was able to come out within a week of us contacting them. The handyman they sent, Joe Cullinan, was punctual, professional and courteous. Got all of the projects done within the allotted time. We were very happy with the services we received and would use them again."

"As there were some water spots on the roof, and after we had a hailstorm recently (past couple of months), thought we had better get someone to come out and look at the roof for a possible roof replacement/repair. Not my house, but my girlfriends house, and I had used Bordner in the past for both an estimate and roof repair and knew about the company. The day Jason was to come out he calls 15 minutes before he shows up to the house, regretfully she was not home as she had to pick up her son and would be back shortly. Jason came and left, and calls and says that he sees that other people had been up on her roof for an estimate, would not provide one to her unless she decides to work with Bordner and would be happy to come back out next week to meet her. Soooo, no estimate for a roof repair (which would be out of pocket) or replacement (insurance coverage). Just that if she decides to go with Bordner they would be working with the insurance adjuster. And why would we decide to go with Bordner on her experience with a 5 minute call? What did Jason do to sell the company and want her to work with you guys? No discussion of how badly damaged her roof was or wasn't, whether it just needed a small repair or extensive damage. No mention of their workmanship, warranty, roofing shingles you use (GAF, CertainTeed, Tamco, etc), whether you subcontract your installers or not, how long you have been in business, didn't leave any information etc. How many visits does it take ? You want us to schedule ANOTHER appointment for you to come out? My impression is that Jason was in between appointments and fit her in and didn't want to be late for his next one. My girlfriend was not gone long, and had she been given a 30 minute notice or more (instead of 15) could have been there to meet him. I am very disappointed in Bordner, will not schedule a 2nd visit to get more information, and am gathering additional information from other companies."

"Mike and Jerry did an excellent job."
