"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

Solar screens are low-maintenance but benefit from occasional cleaning with mild soap and water. Avoid using harsh chemicals or pressure washing, as these can damage the mesh. Inspect screens annually for tears or loose frames to maintain performance. In dusty or coastal areas, more frequent cleaning may be necessary to prevent buildup.

Ensures proper fit and function, maximizing insect protection and airflow.

Solar screens use a thick mesh of polyester to block out the UV waves and solar heat. While they are more expensive at about $7.50 per square foot, they can protect your porch or hardwood floors from sun damage and keep the room or porch on the other side of the patio cool.

You can trim an overhead garage door screen to fit your garage door opening. This is a particularly helpful hack if you have an irregularly sized garage door opening but are still interested in installing a garage door screen to keep pests and debris out. Trim the garage door screen carefully to avoid unsightly edges or an uneven fit.

Yes, you can absolutely put a screen on a casement window, and most casement windows come with screens. Unlike with a double-hung, single-hung, or sliding window, the screen in a casement window sits on the inside of the window so that the sash can freely open outward. Screens are especially important for casement windows because the large window opening the window provides leaves your home more open to bugs and outside debris than most other types of operable windows.
