"Extremely happy with my new windows! I purchased this house in 2019 and the original windows from when the house was first built in the 1960s were still on. They were thin and cracked with rotting wood all around and Right Choice did a great job replacing them. Iâ m saving a huge amount on my electric bill as well!"

"Freddie and his helpers made the windows of this old house shine! They were undaunted by our 2-story house with its old-styled combination windows and the sheer number of windows and panes. They took such care with the window imperfections that made removing them a challenge. I appreciated Freddie’s calm and confident approach to guiding his team and solving problems. I also appreciated his on-site preliminary inspection and costing out the job. He could accommodate my schedule and kept the Communication going over the 1 & 1-2 day job. I also liked the thoroughness in inspecting the work that was done at the end both days, and especially the final day. Freddie and his crew were friendly and I enjoyed meeting them. Coming downstairs this morning to see clean windows felt a bit like Christmas! I recommend them enthusiastically!"

Windows FAQs, answered by experts

You should avoid using abrasive materials and harsh chemicals when cleaning windows. Abrasive tools like scrubbing pads, rough cloths, or steel wool can permanently scratch and damage the glass. Harsh chemical cleaners containing alcohol or ammonia can damage window treatments, frame materials, and special features like tinting. It is also best to use distilled or filtered water instead of hard water, which can leave spots or streaks. For best results, use a clean microfiber cloth to wash the glass and old black and white newspapers to dry it without leaving streaks.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

Casement windows can either be left or right opening, and every window manufacturer makes both so that you can choose which works best for your space. In many cases, you’ll want one left-opening and one right-opening casement window to sit on either side of a picture window or to act as the side panels in a bay window. Just remember that the direction is described from the curb. An FCL (from the curb left) hinges out to the left if you’re looking at the exterior of your home, and an FCR (from the curb right) hinges out to the right.

No, windows cannot be made 100% soundproof. Even the most advanced setups still allow some sound to pass through because windows are designed to let in light and are not completely sealed from the outside. While you cannot achieve complete silence, significant noise reduction is possible, with some noise-reduction windows blocking up to 95% of outside noise.

The goal is to minimize air gaps, add mass, and reduce vibration. To block out as much noise as possible, consider hiring a professional to install new double-pane, triple-pane, or laminated windows. You can further enhance soundproofing with airtight seals, glass inserts, shutters, or sound-dampening curtains. With the right upgrades, you can block out traffic, neighbors, and other city noise to a much quieter level.

Well water can leave ugly marks on your window. A vinegar-water spray will remove most well water stains from your windows. However, you can also use a baking soda paste if the stain is too stubborn. Consider applying waterproofing protection to the glass surface after cleaning for long-term protection. A protective film or spray layer also makes it easier to remove the water stains next time.
