County Service Area

Custom home builder in San Juan County, WA

San Juan County is made up of approximately 20 inhabited islands in the Salish Sea, with San Juan, Orcas, Lopez, and Shaw being the largest. Every building material, piece of equipment, and crew member arrives by Washington State Ferry or private vessel, which directly affects project planning and scheduling. The islands have rugged, rocky terrain with steep slopes on Orcas Island and more gradual topography on Lopez. Salt air exposure from the surrounding marine environment accelerates decay in wood framing, siding, and metal fasteners faster than anywhere else in the four-county service area.

Island Builds Require Planning That Starts Before the Ferry Loads

Every load of lumber, every pallet of concrete, and every piece of equipment that arrives on San Juan, Orcas, Lopez, or Shaw Island comes through the Washington State Ferry system. Ferry service disruptions are a documented reality for the islands, with county officials describing ongoing reliability challenges as the new normal. Material delivery schedules must be built around ferry availability, not the other way around.

Salt air in the San Juan Islands corrodes standard steel fasteners and degrades untreated wood siding within a few seasons. Custom Home Building here requires stainless steel or hot-dipped galvanized hardware throughout, along with exterior cladding materials rated for marine exposure. Skipping those details on an island build means visible failure within five to ten years.

Orcas Island has steep, rocky terrain that limits where foundations can be placed and how equipment can access a site. Concrete Foundations on hillside lots may require hand-digging or small equipment rather than full-size excavators. We plan equipment access and material staging as part of the build design, not as a problem to solve after breaking ground.

Our Services in San Juan County, WA

Every service, available in San Juan County, WA

Custom Home Building and Custom Craftsmanship are the services most requested in San Juan County, where property owners invest in builds designed to last in a salt-air marine environment. Homes on San Juan and Orcas Island need exterior detailing, fasteners, and framing materials selected specifically for coastal exposure. Home Additions are common on Lopez Island and San Juan Island, where existing structures are expanded rather than replaced due to the complexity of bringing in new construction materials by ferry. Kitchen and Bath Remodeling is in steady demand on all four main islands, where vacation and retirement properties are being updated for full-time occupancy.

We loved working with Sam and having him build this wheelchair ramp! He came in under other bids in time frame and cost. Great communicating when he would be on site and when different materials would be available. Respectful of our home and cleaned up really well at the end of the job. Sherman contracting is our new go-to for any contracting job.

Sam came and took a gigantic cottonwood tree down for me at my front driveway. His services were prompt, quality, and affordable. Would recommend to 10/10. Thanks again Sherman General Contracting 🍻

Sherman General Contraction did some significant work on our home. They did a fantastic job and I would highly recommend them. Their lead carpenter was a very skilled craftsman at the highest level.

Jeff Hanson Google review · December 2024

Look no further. Sam is your guy! We just had a full bathroom remodel done and have nothing but great things to say about Sam and his crew. My husband and I have had one bad contractor experience after another for the last 4 years and Sam restored our faith in the industry. All of them are kind, respectful and skilled at what they do. They did absolutely beautiful work; they paid attention to all of the small details and noticed everything before we did so we didn’t have to point out any touch ups. We had a large amount of tile work and it was executed flawlessly. They finished on time and slightly below the estimate. We couldn’t be happier.

FAQ

Custom Home Builder FAQ for San Juan County, WA

Common questions from San Juan County, WA customers about our services, process, and coverage.

All materials and equipment arrive by ferry, so delivery timing depends on ferry schedules and availability. We plan material orders and delivery windows around ferry capacity and build buffer time into the project schedule to account for service disruptions, which are common on the San Juan routes.

Stainless steel or hot-dipped galvanized fasteners are standard for island builds because standard steel corrodes quickly in marine air. Exterior cladding should be fiber cement, cedar, or another material rated for coastal exposure. We specify materials for the island environment from the start of design.

Yes, though steep and rocky sites require more planning around equipment access and foundation method. Some hillside lots on Orcas cannot accommodate a full-size excavator, so we assess site access before committing to a foundation approach. The terrain shapes the build plan, not the other way around.

It is practical, but material lead times are longer because everything ships through the ferry system. We order materials with that lead time built in and coordinate delivery to match the project schedule. Vacation properties on Friday Harbor and Lopez Village are regularly updated this way.

Yes. Custom Craftsmanship, including built-in cabinetry, finish carpentry, and custom millwork, is a service we bring to island projects. We bring the materials and skilled work to the island rather than relying on local supply, which is limited on all four main islands.
