General Construction in San Mateo, CA

The McCarthy Company serves homeowners in San Mateo, CA who are planning a major residential project and want a contractor that can handle it with clear coordination and steady communication. We work on new homes, ADUs, additions, whole-house renovations, and deck construction, along with related structural and finish work.

If you are comparing contractors for a substantial remodel, a new build, or a property improvement that needs careful planning from the start, the next step is straightforward: share your goals, the property conditions, and the scope you have in mind. From there, we can review what the project may require and discuss a practical path forward.

San Mateo projects

Homeowners often reach out when a house needs more usable space, a complete rework of the existing layout, or a new structure that fits the property well. San Mateo includes a mix of residential situations where a project may call for design coordination, structural evaluation, and trades working together in the right order. That can include a new home, an ADU, a major addition, or a renovation that reaches beyond surface finishes.

The McCarthy Company, based in La Honda, serves San Mateo and the broader San Francisco Peninsula with that kind of work. Our role is to help shape the project, coordinate the build, and keep the work moving with attention to both the big picture and the details that affect long-term use.

Project types

For San Mateo homeowners, our work centers on substantial residential construction and related improvements. The services available here include:

• New Home Construction
• ADU Construction
• Home Remodeling
• Home Additions
• Design-Build Services
• Whole House Renovation
• Deck Construction & Replacement
• Kitchen Remodeling
• Bathroom Remodeling
• Foundation & Concrete Work
• Rot Repair & Structural Repair
• Roofing

Kitchen and bathroom remodeling are available as part of larger residential work, but the main focus remains on larger-scale construction. If your project involves opening up a floor plan, building new square footage, replacing aging structural components, or developing a new living space from the ground up, we can help organize the work around that broader goal.

Local property needs

San Mateo homes can come with different planning needs depending on the age of the house, the condition of the existing structure, and the way the property is being used. Some projects begin with a simple idea for more space. Others begin when a homeowner needs to address structural wear, replace a deck, or rebuild parts of a house while keeping the rest of the property functional.

When the scope is broad

Whole-house renovations, additions, and design-build projects often require more than a single trade working in isolation. We look at how the framing, foundation, roofing, exterior surfaces, utilities, and interior spaces fit together so the construction approach supports the entire home.

When planning starts early

For new homes and ADUs, early decisions matter. We help homeowners think through the project layout, site conditions, structure, and the sequence of work before construction begins. That planning stage can make the build more practical and help the finished project align with the homeowner's goals.

When structural work is part of it

Rot repair, structural repair, foundation and concrete work, roofing, and siding-related issues often show up during larger projects. Handling those items as part of the overall construction plan helps avoid disjointed work and keeps the project moving in a more orderly way.

How we work

Residential construction works best when the steps are clear. Our process focuses on the actual work needed to move a project from concept to completion:

1. Understand the goals

   We start by learning what the homeowner wants to change, build, or improve and what matters most for the property.

2. Review the site and scope

   We evaluate the existing conditions, the scale of the project, and any known structural or design considerations.

3. Plan the work

   We help define the scope, coordinate design details when needed, and determine whether engineering or trade coordination should be part of the plan.

4. Manage construction

   During the build, we coordinate the work sequence, keep the project organized, and communicate as the job moves forward.

5. Complete carefully

   We finish the project with attention to fit, function, and the details that matter when the work is meant to last.

For homeowners, that means one point of coordination for a significant residential project rather than a loose collection of unrelated tasks.

Design-build support

Many San Mateo projects benefit from design-build service, especially when the project includes additions, structural changes, an ADU, or a whole-house renovation. In that setting, planning and construction are handled as connected parts of the same project rather than separate steps with no coordination between them.

This approach can be especially useful when a homeowner wants a practical plan for how the project will work on the property, how trades will be sequenced, and how the finished result will support daily use. It also gives room to address related work such as foundation and concrete work, roofing, exterior repairs, or utility coordination as part of a unified scope.

Good fit for larger work

If your project affects multiple parts of the home, design-build can help keep decisions aligned with construction realities.

Useful for new space

ADUs, additions, and new homes often require thoughtful planning before the first phase of construction begins.

Why homeowners call

Homeowners in San Mateo usually contact us when the project is important enough to require clear direction and steady execution. That may mean a new home, a second living space, a major remodel, or a deck replacement tied to broader exterior work. It may also mean a project that starts with a visible issue, such as rot or structural repair, and expands into a larger scope once the property is reviewed.

The McCarthy Company is set up for that kind of work. We handle the planning, manage the construction sequence, and keep the job focused on long-term use rather than quick patchwork. For smaller interior updates, such as kitchen and bathroom remodeling, those services are available when they are part of a larger residential project.
