"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!"

"We had the wonderful experience of having Capital Construction reside our home with Hardie Board in March. The old wood siding had not been kept up and we knew we would need to address it soon, however, we were intimidated by the scale and unknown of the project. The Capital Construction team was informative, not pushy and shared the same passion for our vision for our home. Our project manager, Jay, was personable, communicative with us, and was transparent about possible things that could emerge with the lack of upkeep, so we felt informed in making decisions throughout the process. Eddie and his crew were beyond friendly and impressed us daily with their work ethic. I left for work the morning they started and returned to have find them already having removed all of the old siding in one day. We were informed the project could take 2-3 weeks and they managed to complete it in 6 work days, which blew us away. Eddie also worked with us in developing a custom hay door as part of our vision. We continue to see people slow down and look at the home even months later and we often get compliments from our neighbors. The best feedback came from our next door neighbor who grew up in the home when he walked over and mentioned "I never imagined it could be so beautiful". The pictures speak for themselves. Thank you Capital Construction for helping make the home of our dreams."

"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

If you’re not keen on using a traditional doggie door, there are some alternatives. One popular option is a solid, insulated door that you can lock when you’re out of the home for added security. You can also opt for a doggie screen, which you can lift and lower to allow your pooch access to the outdoors. These are a bit more convenient to use than a regular exterior door, although security could be an issue. You can also install a screen door with a small opening for your pup to prevent bugs from coming inside as your dog exits.

Egress windows require regular maintenance to ensure they function correctly. This includes cleaning the glass, inspecting the frame and well for debris, and making sure the cover or well drains properly. It is also important to check that the window sills and wells are watertight and to inspect and repair any damage to the window frame or seals to prevent leaks and maintain functionality.

There are many ways to customize screens, including customizing frame colors and mesh styles to complement your home’s aesthetic.

Most windows last for 15 to 30 years, depending on the frame material and the glass quality, but most will require repairs during that time. Windows gradually lose efficiency, so it’s usually best to have a window repair technician inspect and service your windows every five to 10 years. You should also repair your windows if you experience the following:

  • Leaks

  • Drafts

  • Difficulty opening or closing

  • Sudden increases in heating and cooling bills

  • Outdoor noise becomes more audible

  • Signs of physical damage

Yes, a variety of screen materials cut out glare from the sun. Solar screen material can block up to 90% of the glare and heat from the sun, saving on cooling costs. It also offers privacy yet unlimited outward visibility. The cost depends on the size of the screen roll, but solar screens cost between $25 and $90 per roll.
