Hello fellow HPers! here is the list of window installers from YOU!!!! Thanks for comments & your personal experiences too! We really appreciate your input and help! Many thanks! Sue :) - - - - - - - - - - - - - - - - - - - - - - - HP WINDOW INSTALLERS recommendation list – Feb2014 I have used and recommend: Window & Kitchen Specialists (412) 366-6800 1667 Duncan Ave, Allison Park, PA 15101 - - - - - - - - - - - - - - - - - - - - - - - Pittsburgh Window and Door I think there in Etna or Millville. Very professional. Sell a product line and reasonable. They installed several storm doors for me. They were better quality than Pella. A fraction of the price. - - - - - - - - - - - - - - - - - - - - - - - We did our own work, but contact my friend at Chris Saxton – Energy Swing Windows They build and install. You can go out and watch yours made http://www.energyswingwindows.com/ - - - - - - - - - - - - - - - - - - - - - - - We've used Thermal Twin to replace all of our windows (didn't do them all at once) and had no problems. They've come out and fixed some screens that were torn from a tree branch and adjusted some windows that wouldn't lock after our house shifted. - - - - - - - - - - - - - - - - - - - - - - - Thermo Twin Windows in Oakmont. Manufacture their own windows. Got good price, good installation and service. www.thermotwin.com/ Windows, doors, siding and more. I was very satisfied with them. They came to the house and reviewed all types of windows they have and gave a free quote. They have vinyl, wood and aluminum. Also got quotes from Anderson Renewal and Pella Windows but their prices were too high. - - - - - - - - - - - - - - - - - - - - - - - We highly recommend Pella, a national firm with a strong Pittsburgh presence. - - - - - - - - - - - - - - - - - - - - - - - We have both Andersen and Pella window replacements. Much prefer Pella even though more expensive. They are thoroughly professional and have returned to correct a problem with one window fastener, years after first installed, for no extra charge. - - - - - - - - - - - - - - - - - - - - - - - We opted for Pella. National company, high quality windows. Excellent installation. - - - - - - - - - - - - - - - - - - - - - - - Thomas Morgan OBHI Lic and Ins 412-805-5602 This is my company. I am backed by 2 companies. It's worth a try to have them talk to you. Thanks, Tom - - - - - - - - - - - - - - - - - - - - - - - Phil Camillo - great work, professional, clean, very reasonable prices. He has done work for me in two different homes, Cell (412) 795-6904 Work (412) 759-1429 ---- an additional comment for 'Phil Camillo' ---- Writing to you made reminded me that I would like to change my basement windows so I gave Phil a call this morning and remembered more about why he's so great: He has come to my home and to my husband's home (before my husband and I met) to do multiple different jobs (replacing exterior doors, storm doors, glass block and pane windows) spanning 5 years. For each job, he was on time, on estimate, and cleaned up everything. He is also courteous, clean, and kind. The products and installations have been stellar. He is the only contractor I have worked with about whom I can say these things. Good luck with your project. - - - - - - - - - - - - - - - - - - - - - - - I had great windows put in by Windows Unlimited. - - - - - - - - - - - - - - - - - - - - - - - We had windows replaced this past year in our upstairs “library” room – Replacements by Anderson… contact name was John Fox. They went in fast and clean and look really nice… insulate well, all that stuff - - - - - - - - - - - - - - - - - - - - - - - We did lots of research. Window Installation Services was top rated on Angies list. They beat prices for quality windows from the various manufacturers. Came when they said they would, did great job, & cleaned up. Windows are great (got Marvin). - - - - - - - - - - - - - - - - - - - - - - - I used to think Thermo Twin Windows were the 'bees knees'. I've recently had quite a few problems-the windows are about 10 years old. Thermo twin will "stand behind" their product for a $65 fee-just to come out and look at the problem. I wouldn't use thermo twin again. - - - - - - - - - - - - - - - - - - - - - - - We used Window World and found them to be the cheapest in their quality grade. We love the windows and didn't have any problems. Best of luck! - - - - - - - - - - - - - - - - - - - - - - - We used Universal Windows Direct. We dealt with one of the owners, Lou Holzer. He was prompt, efficient, and got back to us immediately. The job was bid and it cost exactly what he had down on the proposal. He was recommended by a friend who had many jobs done by him (he also does roofing). His number is: 412-861-6505. - - - - - - - - - - - - - - - - - - - - - - - THE END. Thanks again everyone!
