"Mike was very knowledgeable and courteous about the entire install from laying drop clothes when he worked inside to vacuuming inside and cleaning up anything that was left behind from the old windows and materials from the install of the new windows as well and my husband and I were very impressed with the way the new windows look and how well they work. Karen the salesperson was very knowledgeable and explained what no other company did about how windows are usually made and how they work and what makes windows from Universal so much better than the competition at a reasonable price that added value to our homes equity as well as vastly improving how our home looks inside and out."

"I am extremely happy with AJ's service, start to finish. We initially reached out for an estimate at the beginning of 2015. A representative came to our house to explain all the different products as well as pricing and timing. I had reached out to 2 other companies before hand but was not comfortable their high pressure selling. AJ was very patient with us regarding our timing and budget. I received an estimate on the spot and was able to take my time to review and get back to them. We scheduled the work for May and was able to have 7 Windows removed and replaced in only a few hours. We are very impressed with the quick respond time, professionalism and quality of work including cleanup. We plan on using AJ to replace the remaining Windows as well as a sliding glass door in early 2016.

"We are very pleased. We interviewed a number of security companies and received proposals including DIY to the big national and regional companies. I was not satisfied with any of the companies until I learned of 1stSecurity. Their pricing was good, both for the monthly fee ($40) and for the cost of the equipment. The manager, Jeremy, was very open and straightforward. The installer was also excellent. We asked them to install system prior to a trip we were taking in a few days and they met this short timeframe. The installation took 1-2 hours. The equipment we purchased was fairly extensive as we have a fairly large house and we wanted comprehensive coverage. This included 2 glass break sensors, a motion detector, and numerous door and window switches as well as a fire detection monitor. I accidentally set off the alarm and received a call from the monitoring company in under 10 seconds. The control panel for the system is an easy to use touch screen device, similar to an iPad. The system is very capable so you can connect smart devices to it if so inclined. We have been very pleased with the product and service so far (about 2 months)."

Windows FAQs, answered by experts

Typically, a bay window is, at minimum, 42 inches wide. That said, you can always design a custom bay window that is smaller—box bay windows are usually less than three feet in width and are ideal for smaller spaces.

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

Replacing window glass instead of the entire window is more cost-effective, maintains the frame's aesthetics, and reduces waste. It improves insulation and energy efficiency and can be completed more quickly with minimal disruption to the home.
