A Different Kind of Home Remodel Experience
Most homeowners don't lose sleep over whether a remodel is possible. They lose sleep over how it'll go. Vague estimates, surprise costs, a crew that disappears for a week, decisions no one wrote down. That's the experience Lermaxx Builders was built to replace.
We're a design-build company based in Vacaville, working with homeowners and property owners across Northern California.
Every project runs on documented scopes of work, formal change orders, realistic scheduling, and centralized communication, so you always know what's happening, what it costs, and what comes next. You get experienced construction paired with the organization and accountability of a professionally managed company.
It's a higher standard, and it's the whole point.

Services
Whole Home Remodeling
Reimagine how your entire home lives, from the layout and flow to the finishes, systems, and structural work behind the walls. We handle the full transformation as one coordinated project, so the whole house comes together on one schedule and one standard.
Services
Additions
Grow your home with the extra square footage your family actually needs, built to match and outlast what's already there. We handle the structural, design, and finish work so the new space feels original, not added on.
Services
ADUs & Garage Conversions
Add a rental-ready, multigenerational, or income-producing living space without leaving your property. We manage the design, permitting, and construction so your new unit is built to code and ready to live in.
Services
Kitchen Remodeling
Rework the busiest room in the house with better flow, custom cabinetry, and finishes made to hold up to daily life. We coordinate every trade involved, so your kitchen comes together cleanly and on schedule.
Services
Bathroom Remodeling
Turn a dated or cramped bathroom into a spa-quality space that works beautifully for your morning routine. We manage the tile, plumbing, and finish work down to the tight joints and clean lines that make the difference.
Services
Structural Improvements
Keep your home solid for the long haul with seismic retrofits, foundation reinforcement, load-bearing wall removal, and beam replacement. We coordinate the engineering, pull the permits, and build to code, so the fix is done right the first time and documented for good.
Our Process
We start with a conversation about your goals, budget, and timeline, then visit your property to see the space firsthand. From there, you get a detailed written scope and honest estimate, so you know exactly what you're getting before any work begins.
Once you approve the scope, we handle the groundwork that keeps construction on track. We finalize the contract, coordinate any design, engineering, and permits your project needs, and line up schedules, subcontractors, and materials before we build.
Our crew builds to the approved scope with quality materials, a clean jobsite, and daily communication. We finish with a walkthrough, punch list, and full documentation, and hand you a completed space that's ready to enjoy.
