"Ray the owner was on time, worked fast and did a great job. Our house will sell better because of our sparkling windows. He was friendly and even washed the two little windows on our shed for no charge that were not included in the bid.Our bid also included cleaning out our window wells and cleaning those windows. He did an excellent job. His prices are low. He is a veteran and hires veterans in his business. I would definitely recommend this company for windows and gutter cleaning."

Windows questions, answered by experts

Yes, it is generally better and more cost-effective to replace all your windows at once. Contractors often lower the per-window labor and material costs for larger projects, saving you money in the long run. Installers may also quote a flat rate for overhead, making multiple small jobs more expensive than one large one.

Replacing all windows simultaneously offers other advantages:

  • Aesthetics and Home Value: It creates a cohesive style and uniform energy efficiency, which is appealing to potential home buyers.

  • Efficiency: The entire replacement process, which can take several weeks, is completed in a single, more efficient project.

However, replacing all windows requires a significant upfront investment. While you can replace just a few windows, experts recommend replacing at least five to eight at a time to avoid high overhead costs. An exception is when a single window is damaged; in that case, it can be replaced on its own.

A double-hung window features two operable sashes, meaning it has an upper window part and a lower part that can both open to let in fresh air. A picture window has one fixed glass panel that doesn’t open. Double-hung windows cost about $200 to $2,500, while picture windows cost about $200 to $1,900.

Vinyl window frames are by far the most popular window frames in modern homes. Many favored vinyl frames due to their affordability, durability, energy efficiency, and various colors and styles. Single-pane vinyl windows range from $200 to $900 per window, and double-pane vinyl windows range from $400 to $1,500 per window.

If your windows weren’t manufactured with a retaining clip to receive muntins and hold them in place, you should contact a window company near you to add them for you. A professional will bond the muntins directly to the glass to hold them in place, and they’ll make sure the edges line up nicely with your window frames. If your window does have retaining clips to hold muntins in place, you can just pop the muntins into the clips.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.
