"From beginning to end this was a complete good experience. John came out and showed us the window and explained the process. After doing my research I have found the windows he uses to be excellent quality. Ordered the windows, 12 weeks to the date they were installed. The install was done in half a day. They team was very clean, helpful and complete. They answered all my questions and even let me watch! We noticed a difference within hours of sealing up the windows how cool my second story remained with the Energy Efficient windows in. I cleaned all of them with an easy process of sliding the clips and opening them. What a dream window and only wished we had done this ten years earlier. The windows were 29 years old, solid wood and clad. From the outside you can hardly tell the difference. These were a great purchase, and we are looking forward to having the other 13 windows done with Best Windows."

"Chicago Window Guys provided me with 8 replacement windows in my condo unit. The windows were fitted very well, and they were able to remove my old windows and install my new windows in a very timely manner. In addition, they were able to replace windows on the fourth floor of my building, while many other companies I contacted were not willing or able to do so! The warranty they provide with their windows also provides great peace of mind."

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

Windows FAQs, answered by experts

Glazing is always done from the outside of the window, while the inside doesn’t require any glazing. This is because the main purpose of glazing is to create a weather-tight seal where the glass meets the frame, protecting against drafts and moisture. Since the exterior is exposed to the elements, that’s the side that needs the weatherproofing.

The most likely cause of smearing or streaking after cleaning your windows is residue left on the glass from the cleaner you’re using. Consider diluting the solution and cleaning them again, or use old newspaper to dry the windows after cleaning, as this will soak up any residual material. Additionally, aim to clean your windows on a cool, cloudy day, as cleaners will dry more quickly on the glass if it’s hot and sunny, promoting streaking.

If you decide to forgo your old windows and upgrade them to modern day technology, there may be some people interested in the old windows. You can try selling them on an online marketplace for around $50 to $100 each (so long as the window wasn’t damaged during the removal). This can also help off set the overall price to replace them.

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.

Having a professional caulk your windows will cost you around $50 to $70 per window (or $1.25 to $4 per linear foot), including labor. However, caulking is one of the easiest DIYs there is, and you’ll save a lot of money by getting the supplies and doing it yourself. You’ll only pay $0.05 to $0.20 per linear foot if you DIY this one. Finally, different types of caulk don’t vary too much in price, with most tubes costing no more than $15 apiece (but typically only $3 to $10) at the most.
