Call (803) 680-2547 for a free estimate.
Why Petaluma Homes Are Different

Petaluma’s housing stock spans more than a century, and that changes what a remodel actually involves. Downtown and the neighborhoods around the Petaluma River lean heavily on homes built between 1900 and the 1940s: lath-and-plaster walls, pier-and-post foundations, and framing that rarely runs true. A bathroom gut in a Cherry Valley or Oakhill-Brewster home often means shimming walls before tile work can even begin. Out in the older west side and in pockets like Sunnyslope, you’ll find 1960s and 1970s ranches with their own quirks: galvanized supply lines, undersized electrical panels, and shower surrounds that were never waterproofed to today’s standards.
The climate adds another layer. Petaluma sits in the fog band that rolls through the Petaluma Gap, and mornings bring real moisture even in mid-summer. That ambient dampness shows up as rusted bath fans, swollen door casings, and subfloor rot under poorly sealed tubs. Homes near Adobe Creek or the river corridor deal with higher humidity, so we pay close attention to ventilation and waterproofing on every Petaluma bathroom job. If your home predates 1980, expect at least one surprise behind the walls – and expect a contractor who tells you about it in plain language before the price changes.
Styles & brands we work with







Our Main Petaluma Services
Petaluma homeowners call Mason Remodeling most often for two things: general contracting on additions and structural work, and bathroom remodels in the city’s older housing stock. Each service has its own detailed Petaluma page linked below.
General Contractor in Petaluma
As a General Contractor in Petaluma, we handle the projects that span multiple trades: home additions, garage conversions, kitchen remodels, and structural repairs. Petaluma’s permit process is specific – the city reviews plans through its Building Division, and homes in the Downtown Historic District or within the Riverfront overlay zone may trigger design review. We pull permits, coordinate inspections, and keep the job moving while the city does its review. Every trade on the job is background-checked and identity-verified under The Threshold Standard, and you get a written price covering the full scope before demolition starts.

Bathroom Remodeling in Petaluma
Bathroom Remodeling in Petaluma means working with older floor plans and the moisture realities of the Petaluma Gap. Many of the bath projects we quote involve moving a wall in a 1950s ranch near Corona Heights or converting a tub alcove in a west-side Victorian into a walk-in shower. We check subfloor condition, venting, and supply-line material during the estimate, because those three details drive cost more than any finish choice. A written price comes before any work begins, and the 365-Day Done Right Promise covers the completed bathroom for a full year.

Home Remodeling in Petaluma
Home Remodeling in Petaluma covers the multi-room projects: kitchens opened into dining areas, whole-home updates, and additions that bring a 1,200-square-foot ranch up to modern living standards. Petaluma’s varied lot sizes affect every whole-home plan – the flat, wide lots east of Petaluma Boulevard handle single-story additions better than the sloped parcels up around Westridge. We look at foundation type, ceiling height, and access for materials before we put a number in front of you. That number is written, and it doesn’t change unless the scope changes with your signature.

Brands We Service in Petaluma
Petaluma homeowners sometimes ask whether we work with specific product lines when they’re weighing options. We source specification-grade materials from brands including Kohler, Moen, and Cambria, and parts are stocked through our Bay Area supply partners rather than shipped from out of state – which keeps lead times reasonable.

You’ll get a written price covering the full scope before any work starts – no verbal estimates that grow on the final invoice.
