Steel-framed cedar gates with durable hardware and locks that work from both sides.
DECKS + PATIOS

What We Check Before We Quote
The Rules
A standard residential fence may not require a construction permit, but height, placement and material limits still apply. In many residential zones, fences are generally limited to 6 feet, with additional height allowed for features such as arbors or trellises.
Decks require permits when they are more than 18 inches above the ground, built on a roof or located in an environmentally critical area. We check the address and proposed work before finalizing the scope, then include required permit work in the estimate.
The Ground
Seattle maps steep slopes, landslide-prone ground, flood-prone areas, wetlands and other sensitive sites as environmentally critical areas. Building in or near one can require additional review.
We look at the grade, drainage, retaining walls and available property information before recommending how the project should be built.
The Access
Narrow side yards, steep stairs, limited parking and lots without alley access can change how materials reach the work area. We walk the access route during the site visit so those conditions are accounted for before construction begins.
If the cedar needs to be carried in by hand, that belongs in the quote, not on a surprise invoice later.
How We Build
Quality outdoor construction is not only about how the finished project looks. Material selection, joinery, drainage, hardware, and below-grade conditions all influence how it performs over time.
Cedar Milled by Us
We source Western red cedar logs locally and mill each board ourselves. This gives us direct control over dimensions, quality, and finish while allowing us to produce material outside standard lumberyard specifications.
Designed for the PNW
Our post-on-pipe system anchors galvanized steel pipe below grade and positions the cedar post above the soil. Reducing contact with soil and standing moisture helps protect the base of the post, one of the most common failure points in a wood fence.
Professionally Managed
Knocking Wood is licensed, bonded, and insured in Washington. Clients receive a defined scope of work, detailed written estimate, consistent communication throughout construction, permitting coordination where required, and a labor warranty.
