Renton Siding, Deck & Window Service Contractors | Cobalt Exteriors

We offer a range of services, including siding installation, window replacement, deck design, and even roofing services, helping your home stay in the best shape possible.

Signs Your Siding Needs Replacing

Your home’s siding is the first thing you see outside of your home, and it plays a major role in your curb appeal. As it deteriorates over time, it could lead your home susceptible to repair issues.

Call our siding repair contractors if:

  • Your energy bills are inexplicably on the rise
  • There’s a mildew smell inside your home
  • There are moisture stains on walls and baseboards
  • Your siding is sagging or cracked

The biggest concern for any siding repair issue is always that it allows moisture inside your home. Excess moisture can damage walls, ceilings, and floors, while also putting your home at risk for mold growth. At Cobalt Exteriors, Inc. we offer siding installation and repair services, keeping your home protected at all times.

“Communication is huge for me. They were great from start to finish. There were some delays due to products being delayed, Covid blah blah blah, but they were sure to keep me informed along the way. I change my mind about a design mid project and they had no problem re-doing it for me. Oops! Super friendly staff and owners. I highly recommend!”

“Needing a new roof, I put the job out for bid. The Colbalt Exteriors company was selected to do the job. I found the company professional not only the leadership, but the crew also. The cost was reasonable and fair. and most importantly the quality of the work was outstanding. Working with Kevin and Corbin was a pleasure.”
