"Our dog broke glass in our front window on a cold, Saturday afternooon in January. I called Glass by Ro and they were at my house in under and hour. Not only did they fix the glass, they took, care of the storm window, which had come off. Their work was immaculate and done with efficiency and care. Highly recommend! I would use them again for any window or glass needs. Fabulous work."

"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 questions, answered by experts

Use a high-quality caulk with silicone around your windows, as it’s waterproof and shrink-proof. Or, you can use a caulk consisting of polyurethane or acrylic if you want to be able to paint over it. Caulk made from silicone is not paintable. Avoid using inexpensive caulk that has a resin or oil base. These caulks will not last long and may shrink and pull away from the window as temperatures go up and down.

The purpose of an awning window is to let fresh air into your home without taking up too much wall space. They’re ideal if you live somewhere that gets a lot of rain because their design helps prevent rain from coming into your home. In bathrooms, awning windows also help with ventilation but don’t compromise your privacy.

New window installation costs range from $300 to $1,500 per window, depending on size, material, and energy efficiency features.

Installing glass block windows has benefits and disadvantages, as with most materials. The pros and cons can vary depending on the type of glass block and the window location.

Pros

  • Maintains privacy while letting light into the bathroom

  • Energy efficient

  • Sealed to prevent drafts

  • Aesthetically pleasing

  • Strong and secure

Cons

  • Costly to install

  • Challenging installation

  • Challenging repair

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.
