"Supply chain crisis or not, we eventually got our beautiful window replaced and are so thankful to have it installed before the end of the year and the coldest months. Once our window found its way to Maryland, Horace and team got it to our house and installed within days during a holiday week."

"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."

"A young and energetic crew (in attached photo) arrived on time (9 a.m.) and worked through lunch to complete our new Bay window by 3 p.m. All materials and workmanship are first rate. Color match on the exterior window trim was perfect! I had lots of little requests on touch-up detail work, and they met every challenge. All our questions were answered with a full demo on how the window features, sliding windows and screens, work. We look forward to their return for a second project."

"Glass Impressions did a wonderful job of cleaning all 19 windows in our home, inside & out, including the inside sills, screens and also 2 glass storm doors. Mr. Waters and his team are very good at what they do. They were very reasonable. I plan to use them again, as needed."

Windows FAQs, answered by experts

Folding window installation costs about $1,600 on average, ranging from $500 to $3,000. The cost factors of this project include the size, the type of folding windows, the number of panels, and the type of glass. Different types of folding windows include:

  • Standard folding window: $200 per linear foot

  • Glazed folding window: $240 per linear foot

  • Standard folding window and swing door: $1,000 per linear foot

  • Folding window and sliding door: $2,000 per linear foot

While clean windows don't automatically increase home value, they make your home look more attractive from the outside, and since the exterior is the first thing a potential buyer will see, it can help make a good first impression that paints the rest of your home in a positive light. Educated homebuyers will see that your home is well cared for if they see clean window tracks and sparkling window glass, which can contribute to an overall positive opinion of your property. Clean windows give the impression that the rest of the home—including systems and appliances—is probably well-kept, too.

The average cost to repair a window is about $400, with prices typically ranging from $175 to $1,500. The final cost is influenced by several factors, including:

  • Number of Panes: Single-pane repairs average around $200, double-pane repairs range from $200 to $400, and triple-pane repairs can cost $600 to $1,100.

  • Type of Repair: Minor fixes for a track, seal, or sash are more affordable than repairs for broken glass or window frames, which are typically the most expensive.

  • Window Details: The size, type, and material of the window affect the price.

  • Accessibility: Windows on upper floors or in hard-to-reach locations may increase labor costs.

  • Other Factors: The extent of the damage, local labor rates, and the need for emergency service will also impact the total cost.

For comparison, a full window replacement can range from $175 to $1,800 or more for high-end materials or large windows like bay or bow windows.

The average lifespan for a casement window is around 20 years, but some higher-end casement windows with more durable frame materials can last up to around 40 years before you need to replace them. You’ll need to carry out routine maintenance and window cleaning—and, on occasion, casement window restoration—to extend the lifespan of your casement windows. But they tend to wear more slowly than windows with sliding sashes because the weatherstripping sees minimal friction.

The best thing to clean windows with is a mixture of white vinegar, warm water, and dish soap. This will remove dirt, pollen, and grime without destroying any tints or protective films on your glass. You can also use a commercial window cleaner, but make sure to choose one that doesn’t have ammonia in it, as this can damage window coverings and frame materials over time.
