I contracted them to install Provia windows for my home and he stole a 50% deposit and delivered and installed defective windows. He only installed 4 out of the 5 windows that I ordered and put a deposit on. On top of it, they were defective, but he still installed them. The final window was going to be installed the next business day, but he conveniently decided not to install it. Then, He ghosted me for 45 days after continuously contacting him for a status update, as he was supposedly working with Provia, which he wasn't. Lies after lies. He is highly unprofessional in his business dealings and told me he would NEVER do such a thing to me in 1:1 conversations. Based on this, I entrusted him and gave him a $3500 deposit hoping that he would stand by his word and deliver the windows that I paid for. On top of it, He installed the windows incorrectly and they are leaking air and he doesn't want to own up to his worksmanship issues and fix the issues like a normal dealer would do. This is a company you want to stay FAR away from, as I have incorrect windows installed and he will not take care of any defects or issues with the window mfg. He has stolen my deposit and washed his hands from fixing the issues like a normal business owner should do. There is a right and wrong way to handle any situation and he takes the high road with providing customer satisfaction. I warned you of his shady business tactics!!! RUNNNNNN

After much research and estimates from Lowe's, Home Depot and other contractors, we went with…read moreLandmark Ext. for our windows, interior and front doors and larger/upgraded back patio door. They took the time to explain the differences and warranties promised by the others, and ensure we were making an informed and cost saving decision (although we spent more on our interior (hollow vs. solid)... totally our choice). Worked was described, scheduled and executed as planned, with very little rescheduling (I believe we had 1 hiccup in email correspondence, but that was quickly fixed with a phone call). A beautiful bay window, improved energy costs and 15 doors later... and we're enjoying the investment and partnership with Landmark. Thanks, John and staff!

Peter Pane's does excellent window work - they're an independent business bringing lots of…read moreexperience to the table and will really take care of you! I needed two compliant escape/rescue windows put into Chicago basement bedrooms to replace some older double-hung windows that in no way left a big enough opening for folks to get out. Despite some less-than-enthusiastic responses from other companies, Peter Pane's responded promptly to my job request on Yelp and Ron (who has 40yrs of windows experience!) scheduled to come onsite only a few days out for a review of my needs and to give a firmer quote. One of the window frames was too small for a legal-sized rescue window to just be swapped in, but when I explained my goal to meet code, Ron was able to think through some more difficult-to-install and less common options to put in a larger window (I ended up going with a casement window there and taking out existing framing). I also had concerns about the more common type of window suggested for the other room (he was trying to be price-conscious for me because it's a large one) - and he was concerned about longevity if I got something like a reverse hopper window because of how close to the weight limit that one would be. He was able to suggest a Tilt & Turn window instead, which is uncommon in the States but was exactly what that room needed! Both windows required a custom order and Peter Panes pushed the manufacturer to get the windows made as quickly as possible for me since I was planning for occupants soon. Both windows were done at the earliest point in their estimates (about 4wks) and they scheduled install ASAP. Jensen, Connor, and Ron showed up at my place last week with both windows in tow. We had originally thought some drywall work might be required to fit the expanded window into the first room, but these guys were all pros and were able to adjust the framing and finagle a change in the latch direction on the casement window to make it fit perfectly without having to cut any drywall! They made sure to keep some of the original framing as a template to make a new exterior that matched the arched brick lintel so the outside looks great, too. The second, larger window went in easily and they were meticulous with sealing the outside with foam and the inside with high-quality caulk along the edges. They left the space completely clean, were easy to work with, and were both respectful and non-patronizing (particularly if you are a woman hiring contractors in Chicago, you may unfortunately know how rare that can be!). Both windows look great and work just like I need them to be escape/rescue window code-compliant. The process was smooth from beginning to end, the team was efficient and cleaned up after themselves, and they brought a lot of knowledge to the table. I can definitely sleep at night knowing they helped me get just the right windows with a high quality install and at a fair price. If I ever have any more windows replaced, I will absolutely be calling the team at Peter Panes.

They talked about replacing existing hardware with another window manufacturer. The quote guy, Steve, said their service people are in Rockford area 2-3 times per week. While I waited 2 days for the quote I googled replacing the spring hardware. Parts are available at Lowes and Home Depot for less than $50. The quote I got from this unprofessional small business was for $900. DO NOT ALLOW THIS COMPANY TO PROVIDE SERVICE ON YOUR WINDOWS
