Remodeling Across Yarmouth
What We Build and Renovate Across South Yarmouth, West Yarmouth, and Yarmouth Port
Yarmouth is made up of three distinct villages, South Yarmouth, West Yarmouth, and Yarmouth Port, each with its own housing character. The majority of the town’s single-family homes were built in the second half of the twentieth century, with a median construction year of 1973. Homes that age come with original kitchens, aging decks, dated siding, and bathrooms that have not been touched in decades. That is the work we do here.
Our Services
Kitchen Remodeling
Cabinet installation, cabinet refacing, countertop replacement, island additions and open-concept conversions. The median Yarmouth home was built around 1973, so most kitchens here are still laid out the way that decade laid them out: closed off, compartmentalized, and separated from the living space by a wall that often turns out to be structural. See our kitchen remodeling services for the full scope.
Our Services
Deck Building
Yarmouth has frontage on Nantucket Sound to the south, Cape Cod Bay to the north, and Bass River and Parker’s River through the middle, so a good share of its decks sit on or near water. River and shore frontage brings Conservation Commission review into the schedule, and salt air shortens the life of standard hardware. New decks, repairs, composite and cedar, railings and staining. Full detail at our deck building page.
Our Services
Siding
Vinyl, cedar shake, and fiber cement siding installation and repair, exterior trim replacement, and storm damage repair. Siding on properties north of Route 6 in Yarmouth Port may require Old King’s Highway Historic District Committee review before a permit issues, that is a step we know and handle. See siding contractor services .
Our Services
Bathroom Remodeling
Full bathroom remodels, tub to shower conversions, walk-in shower installation, tile, vanity replacement, and master and small bathroom work. A 1970s Yarmouth bathroom is usually original down to the subfloor, and rot under a tub surround is something demolition finds rather than an estimate predicts. Details on our bathroom remodeling page.
Our Services
General Construction
Home additions, basement remodeling, attic conversions, lead paint removal and second-story additions. In Yarmouth Port, north of Route 6, the Old King’s Highway Committee reviews exterior changes before a permit issues, and the South Yarmouth and Bass River district carries its own separate review. We confirm which one governs an address before any scope is written. For broader scope, visit our general contractor page.
Historic Yarmouth Port
Does My Yarmouth Port Property Fall Under the Old King’s Highway Historic District Review?
West Mountain Construction works regularly on properties subject to the Old King’s Highway Historic District in Yarmouth, and if your property is north of Route 6 toward Cape Cod Bay, the answer is almost certainly yes. The Old King’s Highway Historic District Committee administers the Historic District Act for all properties in that corridor, which runs from Route 6 to Cape Cod Bay and extends to the town’s borders with Barnstable and Dennis. Before any exterior work can proceed, demolition, new construction, changes to the exterior of existing structures, additions, alterations, solar panels, detached garages, sheds, fences, stone walls, even paint, the Committee must review and approve the scope. That review happens before the building permit issues, not after. A contractor who submits to the Building Department first and assumes the historic review is optional will stall your project. We know the sequence: Old King’s Highway review, then building permit, then construction. We file correctly and we do not skip steps. If your project is in Yarmouth Port and involves any exterior change, budget time for that review in your schedule, the timeline varies by the Committee’s meeting calendar and the complexity of what is proposed.
Planning Your Project
Do I Need a Building Permit for Construction Work in Yarmouth, MA?
West Mountain Construction pulls permits for every permitted-scope project in Yarmouth, and the town’s threshold is broad: a building permit is required for construction, reconstruction, alterations, repair, removal, or demolition of a structure, and also for any change of use, and that scope includes work to gas, electrical, plumbing, and heating systems. The Yarmouth Building Department issues all permits, conducts all inspections, and enforces the State building code. They use the OpenGov permitting system for applications. Depending on the nature of the project, the Building Department may also require sign-off from Conservation, Fire, Health, the Old King’s Highway Committee, the Water Department, or the Zoning Board of Appeals before a permit issues, meaning permit timelines vary and cannot be predicted by scope alone. No specific turnaround time is published on the municipal site; the realistic window depends on which other departments are in the review chain. We submit complete applications, follow up with the departments involved, and do not start work before the permit is in hand. If you are planning a project and want to understand what the permitting path looks like for your specific address and scope, that conversation happens during the estimate, at no charge.
Our Standard of Work
Why Homeowners in Yarmouth Choose a Contractor Inspected Beyond the Town Level
Most contractors working in Yarmouth have been inspected by one body: the town’s building department, when a project is done. West Mountain Construction has been an approved vendor at Hanscom Air Force Base since 2016. That status requires documented safety programs, verified insurance, screened personnel, and schedule accountability that is contractual, and it gets re-qualified year after year. A contractor cannot decide to earn that credential next week. It takes a clean record over time, and one failure ends it.
That same standard runs every residential job we take. Marcelo walks every project personally at completion. The punch list gets resolved before we call a job finished, and the one-year written workmanship warranty starts the day you sign off, not the day we started. If something we installed fails because of how we installed it, you call (774) 836-2241. We respond within two business days, inspect it ourselves, and correct it at no cost. No deductible, no debate about whether it qualifies. If you sell the property inside the warranty year, the coverage transfers to the new owner. Materials carry the manufacturer’s warranty separately, and if a product fails, we handle that claim for you.
The 4.8-star rating across 45 Google reviews reflects what that standard looks like from the customer side.

Frequently Asked Questions
Which villages in Yarmouth does a general contractor from Hyannis serve?
We serve all three villages of Yarmouth: South Yarmouth, West Yarmouth, and Yarmouth Port. Operating out of Hyannis puts us roughly ten minutes from each village, and we also cover neighboring towns including Dennis, Harwich, and Barnstable. Contact West Mountain Construction for a free estimate on your Yarmouth project.
Does my Yarmouth Port property fall under the Old King's Highway Historic District review?
Properties in Yarmouth Port sit north of Route 6, which places them inside the Old King's Highway Historic District. That district requires committee review before demolition, new construction, or exterior changes including additions, solar panels, fences, and sheds. We identify whether your address falls under that review during the estimate so the approval path is built into the plan before any scope is written.
Do I need a building permit for construction work in Yarmouth, MA?
A building permit is required in Yarmouth for construction, reconstruction, alteration, repair, removal, or demolition of a structure, and for work to gas, electrical, plumbing, and heating systems. The Yarmouth Building Department issues permits through the OpenGov system and directs applicants to additional sign-offs from Conservation, Fire, Health, or the Old King's Highway Committee when the scope requires them.
Does the South Yarmouth Bass River Historic District affect renovation plans?
The South Yarmouth/Bass River Historic District covers a predominantly residential area along Old Main Street and South Street between South Yarmouth and Bass River, and it carries exterior review requirements that are separate from the Old King's Highway process. We confirm which district governs your specific address before any scope is written, so the correct approval path is part of the project plan from the start.
How does coastal salt air affect construction decisions in Yarmouth?
Salt-laden air accelerates corrosion of metal components and deterioration of finishes on properties throughout Yarmouth. We account for that condition in material selection and installation method before work begins, not after a callback. The same documented safety and quality process that satisfies federal inspectors at Hanscom Air Force Base applies to every Yarmouth job we take.
