Remodeling Across Dennis
What We Build and Renovate Across Dennis’s Five Villages
Dennis is one town made up of five distinct villages, Dennis, Dennis Port, East Dennis, South Dennis, and West Dennis, each with its own post office and its own character. The housing stock runs from mid-century seasonal cottages on crawl spaces to antique Capes with lath-and-plaster walls, so scope varies considerably from one street to the next. Homes of 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. Dennis housing splits two ways: mid-century seasonal cottages built over crawl spaces, where plumbing and electrical runs are shallow and tight, and antique Capes with lath and plaster walls. The same kitchen scope is a different job in each. See our kitchen remodeling services for the full scope.
Our Services
Deck Building
Dennis enforces its own wetlands bylaw, and no work may alter land within one hundred feet of a resource area without Conservation Commission approval, which takes in a lot of deck projects on both the bay and sound sides. We flag that setback at the assessment rather than after demolition. 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 Dennis sit inside the Old King’s Highway Regional Historic District and need 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. In a seasonal Dennis cottage the bathroom usually sits over a crawl space, so access and freeze protection for the supply lines are part of the design rather than an afterthought. Details on our bathroom remodeling page.
Our Services
General Construction
Home additions, basement remodeling, attic conversions, lead paint removal and second-story additions across all five villages. North of Route 6 the Old King’s Highway Committee reviews exterior work, South Dennis has a district of its own, and every permit now files through the OpenGov system the town moved to in January 2025. For broader scope, visit our general contractor page.
Historic Districts in Dennis
Does My Dennis Home Fall Inside a Historic District?
Dennis has two historic districts, and your village decides which one applies to your property. The Old King’s Highway Regional Historic District covers everything north of Route 6. It was established in 1973 and runs from Sandwich to Orleans along Route 6A, taking in the north-side villages. The South Dennis Historic District is a separate designation covering a defined area within South Dennis, and it operates under its own committee scope. If your home sits inside either one, exterior changes require Committee review before a building permit issues, and that includes siding material, windows, trim profile, fences, signs, new construction and demolition. The Committee weighs historical value, general design, the proportion of building elements, texture and materials. The sequence is review first, then permit, then construction. A contractor who files with the Building Department and treats the historic review as optional will stall your project. If your address is in South Dennis, confirm the parcel boundary with the Town before planning exterior work; the Building Department can direct you on (508) 760-6157.
Planning Your Project
Who Pulls the Building Permit for Construction Work in Dennis?
West Mountain Construction pulls the permit on every permitted-scope project in Dennis, and managing it is not the homeowner’s job. Permits are administered by the Town of Dennis Building Department, which moved its permitting to the OpenGov platform on January 13, 2025 for building, plumbing, gas, electrical and zoning filings. All new residential and commercial buildings require a final as-built survey before a Certificate of Occupancy issues. Dennis has adopted the Massachusetts Stretch Energy Code and the 2018 International Energy Code, and the 10th Edition of the Massachusetts Building Code is now the controlling edition. Fee schedules and project-type thresholds were not published on the Town’s municipal pages when this was written, so confirm current requirements with the Building Department on (508) 760-6157 before assuming a scope is permit-exempt. We submit complete applications, follow up with the departments in the review chain, and do not start work before the permit is in hand.
Our Standard of Work
Why Homeowners in Dennis Choose a Contractor Inspected Beyond the Town Level
Most contractors working in Dennis 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
Does my Dennis home fall inside a historic district?
Dennis has two historic districts: the Old King's Highway Regional Historic District, established in 1973 and covering all properties north of Route 6, and the South Dennis Historic District. The Old King's Highway Committee reviews any exterior change, new construction, fence, sign, or demolition, weighing historical value, proportion, materials, and design. We identify district status at the estimate stage so the review is built into the schedule before work begins.
Who pulls the building permit for construction work in Dennis?
The Town of Dennis Building Department administers all building, plumbing, gas, electrical, and zoning permits, now processed online through OpenGov since January 2025. All new residential and commercial buildings require a final as-built prior to the town issuing a Certificate of Occupancy. We coordinate directly with the department and confirm current requirements for your specific scope before the project starts.
How do I know a contractor working in Dennis is actually qualified?
Verify the state license numbers directly with the Commonwealth. We hold MA Construction Supervisor CS-122691 · Construction Safety Specialist J-C-7-1U9S8N3 210793 · Home Improvement Contractor 188708. Beyond state licensing, we have maintained approved vendor status at Hanscom Air Force Base since 2016, a standing that requires annual re-qualification, documented safety programs, and inspections by federal inspectors who have no interest in how friendly we are.
Does work near wetlands in Dennis need Conservation Commission review?
Dennis enforces its own wetlands bylaw: no person may remove, fill, dredge, or alter land within one hundred feet of resource areas including banks, freshwater wetlands, and coastal areas without Conservation Commission approval. We flag wetland setbacks at the assessment stage, not after work has started, so the review timeline is accounted for in the project schedule from the beginning.
Do contractors working in Hyannis also serve Dennis on the same project?
Projects that span the town line between Hyannis and Dennis do not require a second contractor. We serve both towns under the same documented safety program and contractual scheduling. Every installed scope in Dennis carries a One-year written workmanship warranty on every installed scope. Materials are not covered by this warranty and are subject to the manufacturer's warranty.
