"Thank you Aaron and Bob for another excellent joy with another window project. We are equally thrilled with the workmanship of the installation and the quality of our new window as we were the last time you did a big window job for us. We appreciate your professionalism and dependability."

"We just needed the pane in one window replaced. They came to look at it the same day I called. He measured and ordered the window in less than 10 mins. As he said, 10 days later the window pane arrived. They came and installed the window that day in less than half an hour. The service was great, timely and affordable. I will definitely remember them for any future window replacements."

Windows questions, answered by experts

Window capping costs between $1 and $2 per linear foot. Since your average window size is 24 by 36 inches, you’re looking at 10 linear feet in total, or $10 to $20 per window. Labor adds another $30 to $100 per hour to the project. If you have custom windows, you’ll spend more to have your windows capped. Fiberglass tends to cost more than vinyl and aluminum, while vinyl costs the least but has the shortest lifespan and may have a higher long term cost.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

It is legal to put bars on windows in most places, but it depends on the type of bars you choose and the regulations in your area. For example, there are building codes in Mississippi, California, and Texas that forbid the use of permanently closed burglar bars on windows due to concerns about people getting trapped inside during fires.

It is generally recommended to remove window screens for the winter, especially in climates with heavy snow, freezing rain, or frigid temperatures. Removing them helps prevent damage to the screen mesh and frames that can be caused by ice and moisture buildup between the screen and the window. Taking out the screens also allows more natural light and warmth into your home during shorter winter days and makes it easier to clean your windows thoroughly. In warmer climates where harsh weather is not a concern, the decision is more about personal preference; some homeowners prefer the clearer view, while others leave them in for convenience.

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.
