"The install took 2 days which is what we were told before the work started. Everyone was great to work with and we would highly recommend them to anyone looking to have an egress window installed!"
"We just had Unicorp install new windows throughout our entire house. The window quality is excellent and the installation went very well. We were replacing 55 years old windows - and were very happy with the entire process, from selection, exterior color choices, and finally installation."
"Received very informative presentation on what to ask and look for when window shopping. The only reason I didn't go with WoW was due to another company being slightly less expensive."
"I would recommend this company to anyone needing glass repair. We had window glass replaced that had broken seals resulting in foggy windows. They were professional and got the job done right after the ordered glass arrived. I will use them again if needed."
"I was very happy with response from Eddis. He gave me a quote upfront and followed it up with an invoice via email. I paid him half at the beginning and another half when he came back to install the window. He was very professional and respectful of my house. I will definitely use A.R. Glass again if I have window repair needs."
"I had new glass installed in a patio door, a three window bay with floor to ceiling glass, and a front window. All were custom wood windows that were old. Metro did an outstanding job. They had a competitive quote. They were professional and friendly. They cleaned up after the work. My wife was happy. All good. High recommend."
"The Premier Windows and Glass has provided an excellent service for me! A frame of one of the windows in my condo was broken, and I looked for a company that would fix it and prolong the life of the window. So, I was very happy to discover The Premier Windows and Glass. Their technician was very polite, professional, and knowledgeable. Not only did he do a quality job on fixing the frame, but he also explained to me what needs to be done to prevent the window from breaking down again and avoid paying a lot of money for its replacement. In addition, the manager and technician responded to my service request in a prompt manner. The problem was solved on the day when I called the company. Last but not least, the company offers competitive service rates and does not push people to spend more money than is absolutely necessary. I would strongly recommend this company to anyone who needs to have a window fixed or replaced."
"Highly recommend this company for window repair. Highly professional, friendly and helpful. Pointed out issues we had missed and fixed all issues quickly with high quality work. Repaired/replaced windows which had blown seal/discolored, repaired window to smoothly open, fixed window screens. Could not recommend them more."
"Fantastic experience with JS Jackson! They did 2 projects for us - window replacement (6 windows for a townhouse) and cut and install new kitchen window. The leads on each project were very knowledgeable and great at explaining the process, answering questions, and advising on the best products for quality, budget, design, and function. Workers were friendly and professional. The office staff is very responsive at handling scheduling, permits, invoices, etc. It’s been several months and the windows are clearly properly installed, well-sealed, no leakage, and outside framing looks flawless. Would hire again!"
Wood windows fall in the middle of the window frame materials when it comes to energy efficiency. They’re more insulating than aluminum and vinyl, but they aren’t as efficient as fiberglass or composite frames. If you love the look and lifespan of wood windows and want to maximize efficiency, you can upgrade to double-pane or triple-pane glass and consider window tinting and low-emissivity (low-E) coatings to minimize heat transfer.
Mulled windows are often more expensive than standalone windows. However, this is mostly because mulled windows tend to be larger than standard windows, meaning they require more materials and labor to manufacture and install, both of which drive up the cost. If mulled windows take up the same square footage as separate windows, they should cost about the same unless you need to reinforce your exterior wall to support the larger wall opening.
A double-hung window features two operable sashes, meaning it has an upper window part and a lower part that can both open to let in fresh air. A picture window has one fixed glass panel that doesn’t open. Double-hung windows cost about $200 to $2,500, while picture windows cost about $200 to $1,900.
When specifying window sizes, manufacturers use a standard four-digit code system. The first two numbers represent window width, and the last two represent window height. For example, a window with a code of 2917 has dimensions of 2 feet, 9 inches wide by 1 foot, 7 inches high. Windows with even dimensions include zeros as placeholders. For example, a window that is 5 feet wide by 2 feet high would have a code of 5020.
When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all your windows simultaneously.
When buying new windows, you should consider energy efficiency, safety, and aesthetics to choose the right window for you.
