5-Star Google Reviews for Siding and Dry Rot Repairs

I had a leaky window, and SFW was fantastic at resolving the issue. Water was getting behind the siding due to improper construction when it was initially built. SFW Construction sent two carpenters to my house. They quickly determined the root cause of the issue, explained what they would do to fix it—and gave me a ballpark estimate of what it would cost. They then went to work to start fixing the leaking window. They exceeded my expectations, and the cost was a little under the ballpark estimate I was given. Very professional, considerate, and didn’t waste any time or materials. I will not hesitate to contact SFW again. They are absolutely fantastic!

Targeted Siding Repairs

Why Siding Repairs Are Paramount

Siding is the first layer of defense in your home’s building envelope system. Your siding protects your moisture barrier, flashing, and other waterproofing components.

In short, it keeps the water out and protects the structural components from dry rot—designed to prolong the life of the outer layer of your home.

Dry rot occurs when timber remains damp for an extended period, creating an environment for wood-destroying dry rot. Improper deck flashing is the main cause, as it allows water to enter the deck-home junction. Properly flashing the deck's ledger board where it meets the home is critical in preventing dry rot.

Lead Paint Removal Project Green Lake Neighborhood

Seattle Lead Paint Removal. “Where do we start?” It's a question we often get asked when working on turn-of-the-century homes. From a contractor’s perspective, the answer is simple. “Let’s start with safety.” In this case, lead paint. Typically, when the paint fails, it stems from a moisture issue. For instance, it could be because of a leaky gutter, a lousy piece of roof flashing, or any other form of water intrusion. In most cases, especially in new construction, it means a lot of rot, which typically happens in less time; when it comes to older homes, that generally is not the case.

Granted, these paint failures are often mistaken for siding failures. In most cases, the siding underneath is outstanding. Although with enough exposure, all wood will succumb to dry rot.
