What we build

Craftsmanship across
every scope of work.

From a single bathroom renovation to a full addition with structural work, Hart Construction brings the same standard of quality and personal oversight to every project.

01

Custom remodels & additions

Full-scope residential remodels that transform how you live in your home. We manage every phase — design coordination, permits, subcontractors, and finish work.

02

Kitchens & bathrooms

The rooms that sell homes and make daily life better. We work with your designer or ours to deliver high-end results that hold up for decades.

03

Framing & foundations

Structural work is where shortcuts show up later. We do it right the first time — clean framing, solid foundations, no surprises down the road.

04

Decks & outdoor living

Sonoma and Marin are made for outdoor living. We build decks, covered patios, and outdoor structures that extend your home into the landscape.

05

Garages & ADUs

Accessory dwelling units and garage conversions are one of the best investments a California homeowner can make. We handle the full scope, permits included.

06

Flooring

Hardwood, engineered, tile, and luxury vinyl — we install flooring that performs beautifully for the long term, with clean transitions and proper substrate prep.

07

Tile installation

From shower surrounds to kitchen backsplashes to outdoor patios, precise tile work that is level, tight, and built to last.

08

Fencing

Wood, cedar, and custom fence and gate installations that add privacy, security, and curb appeal to your property.

09

Retaining walls

Engineered to hold, built to look good. We construct retaining walls that manage slope and erosion while complementing the architecture of your home.

10

Concrete & flatwork

Driveways, walkways, patios, and steps — poured and finished to a high standard with proper drainage and long-term durability in mind.

11

Exterior siding & trim

New siding, trim replacement, and exterior envelope work that protects your home from the elements and refreshes its appearance.

12

Windows & doors

Supply and installation of windows and doors — from single replacements to full-house upgrades that improve energy efficiency and security.

13

Full project management

One point of contact from consultation through completion. No handoffs, no communication gaps, no surprises on the invoice.

About Christopher Hart

Built on craftsmanship,
run with integrity.

Christopher Hart has been building and remodeling homes in Sonoma and Marin Counties for over 15 years. He started Hart Construction because he believed homeowners deserved a contractor who shows up, communicates clearly, and delivers exactly what was promised.

Every project is personally managed by Christopher — not handed off to a foreman you'll meet on day one. That means consistent quality, honest timelines, and a finished result you're proud to live in.

How it works

A straightforward process,
start to finish.

We keep things simple and transparent. No surprises, no runaround — just clear communication and quality work from the first meeting to the final walkthrough.

01

Consultation

We meet on-site to walk through your project, understand your goals, and talk honestly about timeline and budget. No pressure, no pitch.

02

Proposal

Within a week you'll have a detailed written scope and a fixed-price estimate — no vague line items, no hidden costs.

03

Construction

Work begins on a clear schedule. You'll get regular updates and Christopher is reachable throughout. Your home is treated with respect.

04

Completion

We do a final walkthrough together, close out any punch list items, and follow up after move-in to make sure everything is right.
