Belmont Construction Expertise

Craftsmanship With Context

Belmont’s terrain, architectural mix, and city permitting environment require experienced construction leadership. De Mattei Construction is known for delivering remodels and additions that feel seamless—both structurally and visually.

We are familiar with:

Hillside construction requirements
Soil and foundation considerations
Neighborhood compatibility and design review expectations
Efficient permit paths with the City of Belmont

Our teams are skilled at advancing projects smoothly—even when working with older infrastructure or completing detailed finish work that must align perfectly with existing conditions.

From Planning to Completion — A Fully Managed Process

Successful remodels start long before construction. We collaborate early with homeowners, architects, engineers, and designers to establish:

Realistic timelines
Structural feasibility
Material and finish alignment
A clear, predictable project scope

With in-house project managers, long-standing local subcontractors, and meticulous jobsite coordination, we deliver projects with craftsmanship, safety, and consistency at the forefront.

Your finished home will feel renewed, curated, and unmistakably Belmont—beautifully connected to both its history and your lifestyle.

Do I need a permit for a remodel or addition in Belmont?

Yes. Most remodels, structural changes, additions, ADUs, and major interior upgrades require permits through the City of Belmont Community Development Department. Even kitchen and bath remodels often need permits for electrical, plumbing, and mechanical upgrades. We handle the permit coordination process on your behalf.

How long does the permitting process usually take in Belmont?

Permit timelines vary based on project scope and city review workload. Smaller remodel permits may take 4–8 weeks, while additions or ADUs may require 8–16+ weeks for review and revisions. Starting design and planning early helps keep the schedule on track.

What types of homes are common in Belmont, and how does that affect construction?

Belmont has a mix of mid-century homes, ranch-style residences, hillside homes, and custom builds. Many properties are on slopes, which can require geotechnical reports, foundation engineering, retaining walls, or drainage improvements. We have extensive experience working with these conditions.

Can you help with design, or do I need to hire an architect first?

We work with both models. We can partner with your architect or recommend trusted local architects and designers. We prefer to collaborate early to ensure structural feasibility, realistic budgeting, and smoother permitting.
