County Service Area

Custom home builder in Whatcom County, WA

Whatcom County stretches from Bellingham's waterfront neighborhoods to the rural foothills near the Canadian border. The county averages over 40 inches of rain per year, concentrated in fall and winter months. That sustained moisture drives wood rot, foundation saturation, and crawl space issues in older homes throughout Bellingham, Lynden, and Ferndale. Coastal areas like Birch Bay face compound flood risk from both sea-level exposure and the Nooksack River, which directly shapes how foundations and concrete flatwork must be designed here.

Sherman General Contracting LLC in Whatcom County, WA

Built for Whatcom's Wet Winters and Flood-Prone Lowlands

Bellingham's older neighborhoods, including Fairhaven and the Lettered Streets district, contain Craftsman-era homes built in the early 1900s. These homes often have undersized foundations, aging framing, and no vapor barriers. Whole House Remodeling in these areas requires careful structural assessment before any walls move or additions go up.

The Nooksack River floodplain covers parts of Lynden, Everson, and Sumas. Concrete foundations and flatwork in these zones must be elevated and reinforced to handle seasonal saturation. Ignoring soil drainage conditions here leads to cracked slabs and heaving flatwork within a few seasons.

Ferndale and Blaine are seeing active residential growth along the I-5 corridor, with new subdivisions replacing former agricultural land. Residential Land Development on these converted parcels requires soil testing and proper site grading before any building begins. We work through those site conditions from the ground up, not around them.

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.

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 Whatcom County, WA

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

Yes, but site conditions matter a great deal. Floodplain parcels in areas like Everson and Sumas require elevated foundations and specific drainage design to meet county standards. We assess soil saturation and elevation before any foundation work begins.

Older Craftsman homes in that area often have original framing, minimal insulation, and foundations that were not designed for modern loads. A full remodel typically starts with a structural review, then addresses framing, moisture barriers, and updated mechanical systems before cosmetic work begins.

ADU construction works well on the larger residential lots common in Ferndale and Lynden. Lot size, setbacks, and utility connections all factor into the design. We handle the full build from foundation to finish.

Over 40 inches of annual rain means soil stays saturated for long stretches in winter. Concrete flatwork poured without proper base preparation and drainage will crack and heave. We grade and prepare the sub-base to account for Whatcom's wet conditions before any concrete is placed.
