"Devon is, simply put, an incredible contractor. Having dealt with many others in the past, I was pleasantly surprised by Devon's unwavering efforts to keep me apprised of every step of the siding/trim job. He went above and beyond my expectations, even taking the time to update me with pictures and videos to show the project's progress. Devon is a rare gem in this industry; he is extremely responsive, diligent, timely and talented — and not to mention, a very kind and friendly person. Any questions I had were answered right away and he always made sure to run next steps by me before proceeding. I cannot recommend DMM enough. He will blow you away with the beautiful quality of his work, attention to detail, and the dedication he puts into his craft. It's not just another gig to him — he truly cares about making your vision come to life. One of the best decisions I made for my new house. Thank you DMM!"

"Dustin C. @ DaBella Boise helped us choose the right windows for our application and personally monitored progress from order to completion. The finished product looks great, but the best part is instantly seeing and feeling the difference between modern tech vs. 40y old aluminum framed windows. No more drafts or condensation! Thanks DaBella!"

"I hired Cody for so many projects! He painted my roof, the outside of my house, detailed work inside. He re-glazed my windows, sanded and painted my ceilings, repainted my radiators, and more. His work is perfect and detailed oriented. He also staged my house painting over the course of the summer in order to make it easy for me to pay for it. Cody is also extremely polite and pleasant to be around. I highly recommend him."

Window Door Contractors FAQs, answered by experts

The screen on many screen doors is held in place by screen spline. Screen spline is typically a thin vinyl tubing that fits into the groove of the door’s frame and holds the screen in place. To install the spline on a screen door, you’ll need a spline roller—a tool that presses the spline and screen into the door’s narrow groove. Note that old spline can crack and break, so replacing your screens is a good time to replace the spline, too.

Yes, adding windows adds value to a brick house. Homeowners don’t shy away from more natural light and an opportunity to get fresh air. Adding a window is particularly beneficial if you live in an area with good weather for much of the year or if your home has a nice view. Keep in mind that many older brick homes have historic wood windows that add to the charm of the house. When you install a new window in a brick house, you’ll want to find one that matches the aesthetic of the existing windows.

While windows increase a home’s value, how much they increase it can vary. It depends on the age of the home and the type of windows. You can expect about 70% to 85% return on investment (ROI) when adding a window to your home.

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.

Screen repair is always worthwhile, as tears and holes in your windows and door screens are unsightly and allow pests and debris into your home, rendering the screen useless. The faster you repair your screens, the faster you can open your windows and doors freely to let the fresh air in. Consider repairing multiple door and window screens during one appointment with a screen repair technician to make the investment and labor costs worth it.

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.
