Licensed and insured general contractor serving Watertown homeowners with custom homes, additions, and renovations since 2004.
When Your New Construction Needs a Fresh Start
Not every construction project goes as planned. Sometimes a build stalls — whether from contractor disputes, financial issues, or simply poor execution. The homeowner is left with an unfinished structure that's been exposed to the elements, and no clear path forward.
That's exactly the situation we stepped into in Watertown. A new construction home had been sitting unfinished for two years. No siding. No interior finishes. Windows were developing mold from lack of climate control. The deck framing was exposed and deteriorating. The homeowner needed a contractor who could assess the damage, develop a plan, and execute every remaining phase to bring the home to completion.
North Heritage Construction took over the project and completed all finish work — interior and exterior — delivering a fully finished custom home. We replaced compromised windows, installed all siding, completed the deck, and handled every interior finish from trim and doors to tile, fireplaces, and stairs.

Our Services in Watertown
From new construction completion to full-home renovations, we handle every phase in-house.
New Construction Completion
When a build stalls or a previous contractor leaves a project unfinished, we step in. We assess what's been done, identify what needs repair, and execute every remaining phase to deliver a completed home.
Interior Finish Work
All interior finishes from start to finish — trim, crown molding, baseboards, interior doors, stairs, tile work in bathrooms, finish plumbing, fireplaces, and hardware. Every detail executed to a high standard.
Exterior Finish and Siding
Complete exterior finish including siding installation, window replacement, exterior doors, deck completion, and weatherproofing — protecting the home and giving it the finished appearance it deserves.
Damage Assessment and Repair
Homes that sit unfinished suffer weather damage, mold, and material deterioration. We identify and repair compromised elements — replacing windows, treating structural issues, and ensuring code compliance before finishing.

Common Questions
Frequently Asked Questions
How much does a home addition cost in Watertown, MA?
Home additions in Watertown typically range from $200 to $400 per square foot depending on complexity and finish level. A first-floor addition generally runs $80,000–$150,000. A two-story addition with full interior finish typically starts at $200,000. We provide a detailed, itemized estimate after walking your property.
Do I need a permit for a home addition in Watertown?
Yes — all structural additions require a building permit in Watertown. North Heritage handles all permit applications and inspections as part of every project. Watertown's building department typically takes 3–6 weeks to approve permits; we factor this into the project schedule from day one.
How long does a home addition take in Watertown?
Most home additions take 3–6 months from permit approval to final walkthrough. A first-floor addition can be completed in 10–14 weeks. A two-story addition with full interior finish typically takes 4–6 months.
What types of projects do you build in Watertown?
We build home additions, kitchen and bathroom renovations, full home renovations, new construction, decks, and structural work in Watertown. The town's mix of single-family homes, capes, and colonials is well suited to additions and modernization projects.
Will my addition match the existing house?
Yes — we match rooflines, siding, window styles, and exterior trim so the finished addition looks like it was always part of the original home. A well-matched addition adds value and looks right. A poorly matched one is obvious and hurts resale.
Do you use subcontractors?
Our own crew handles all carpentry, framing, roofing, siding, and interior finish work. For licensed trades — plumbing, electrical, HVAC, insulation, and plaster — we work with trusted specialists. Our team manages the site every day.
