Our Whole-Home Remodeling Services

Interior Reconfiguration & Design

Whole-house remodeling is often about more than new finishes—it’s about how your home actually lives day to day. We can remove walls, reconfigure layouts for open-concept living that suits busy tech families, and create entirely new spaces such as dedicated home offices, wine cellars, fitness rooms, or bonus suites. Throughout every change, we work closely with structural engineers and city requirements to ensure that all modifications are safe, permitted, and structurally sound. You get the airy, functional layout you want, backed by decades of construction experience.

Kitchen & Living Spaces

In most complete home makeovers, the kitchen becomes the centerpiece of the design. As part of your custom home remodel, we provide a full kitchen redesign that may include new layouts, islands, premium appliances, and custom cabinetry that flows seamlessly into updated living and dining areas. Open sightlines, better circulation, and comfortable gathering spaces turn your main floor into a true hub for entertaining and everyday family life. When you’re ready to go deeper, our dedicated Kitchen Remodeling page walks through the details of our kitchen redesign capabilities.

Bedrooms & Bathrooms

Luxury whole-home renovation means every private space feels intentional and elevated. We renovate primary suites with spa-inspired bathrooms, generous custom closets, and quiet sitting areas for unwinding after a long day. Secondary bedrooms are refreshed for kids, guests, or multi-generational living, while bathrooms are upgraded with features like steam showers, freestanding tubs, heated floors, and layered lighting. For more detail on these spaces, you can explore our Bathroom Remodeling services as a companion to your whole-house remodeling plan.

Home Systems Upgrades

Behind the walls, a successful entire house renovation includes updating systems you may not see but rely on every day. We upgrade electrical panels and wiring, replace or reconfigure plumbing, modernize HVAC for efficiency and comfort, and integrate smart home systems for lighting, security, and climate control. These upgrades are designed to improve safety, energy performance, and convenience—critical for high-end Silicon Valley homes where expectations are high and technology moves fast.

Exterior & Additions

Many complete home makeovers extend beyond the interior. Calwest Builders can refresh exterior facades with new siding, stucco, or trim details; replace windows and doors for better performance and curb appeal; and update roofing as needed. When your vision calls for more space, we can integrate new square footage through thoughtful Home Additions—such as expanded great rooms, new suites, or attached guest spaces—so the final project feels cohesive from the driveway to the back patio.


The Calwest Difference in Home Remodeling

Experienced Oversight on Every Project

Your whole-house remodeling project is led by principals who bring decades of hands-on construction experience to the table. Bill and Bob personally oversee custom home remodels from Redwood City to Atherton, applying their backgrounds in fine carpentry, multi-million-dollar estate work, and high-end residential construction. Their involvement ensures that design intent, engineering, and field execution stay aligned from the first walkthrough to the final punch list. With seasoned leadership on site and behind the scenes, details don’t get missed.

Detailed Planning, Permits & Roadmaps

A full home remodel is a major undertaking that touches nearly every surface and system in your house. We start with an in-depth assessment, then build a clear project roadmap that includes phasing, realistic timelines, and a transparent budget. Our team handles all permits and inspections, navigating complex jurisdictions in cities like Palo Alto, Los Altos Hills, Atherton, and other Peninsula communities so you don’t have to. You get a well-structured plan from day one, reducing surprises as work progresses.

Quality, Consistency & Custom Millwork

When you’re upgrading an entire house, consistency in quality matters as much as any single design choice. We prioritize cohesive design elements—aligned trim profiles, coordinated hardware, and a unified palette of materials and finishes—so each room feels like part of a thoughtfully curated whole. Drawing on deep millwork expertise, we can produce custom built-ins, paneling, and architectural details that tie spaces together and elevate the overall result. Every room receives the same level of care, rather than a few “hero” spaces standing out from the rest.

Minimal Disruption & Transparent Communication

We recognize that a complete home makeover affects your daily life, even if you move out during construction. Our team sequences work in logical phases, coordinating trades to avoid downtime and keep momentum. Using modern project management tools and client portals (such as JobTread or similar platforms), we provide regular updates, photos, and clear communication so you always know what’s happening each week. The goal is to minimize disruption while keeping you fully informed and confident in the progress.


Our Whole-Home Remodeling Process

Comprehensive Consultation & Vision

Every entire house renovation begins with a deep dive into how you live today and how you want to live tomorrow. We walk through each space with you, discuss your priorities, and take note of the luxury features on your wish list—such as home theaters, second kitchens, guest suites, or dedicated hobby spaces. If your project involves significant structural changes or detailed interior design, we collaborate with or recommend trusted architects and interior designers to round out your team. From the start, our aim is to build a shared vision for your complete home makeover.

Design Development & Permitting

Once goals are clear, we move into design development and documentation. Architectural plans, engineering as needed, and specifications for finishes and fixtures are created so everyone is working from the same playbook. Our team then submits drawings to the appropriate city or county—whether in San Mateo or Santa Clara counties, including stricter jurisdictions like Atherton and Woodside—and coordinates feedback, revisions, and approvals. By handling these details, we streamline the path from concept to construction.

Full-Scale Construction & Project Management

With permits in hand, we transition to construction in a structured sequence: demolition, framing and structural changes, rough-in work (plumbing, electrical, HVAC), insulation, drywall, and finally fine finishes. You’ll have a dedicated point of contact overseeing daily activities, coordinating subtrades, and ensuring that craftsmanship meets Calwest’s standards at every step. Weekly on-site meetings, progress photos, and status updates keep you in the loop, whether you’re living nearby or managing the project from a busy work schedule.

White-Glove Project Completion

As the construction phase wraps up, we move into a detailed completion process. This includes thorough quality checks, system testing, and a full professional clean so the home feels truly turn-key. We walk the property with you room by room, creating and resolving a punch list quickly so every detail is dialed in. The final experience is walking into a fully refreshed home that feels brand new—only this time, it’s designed precisely around how you want to live.

Unlock the full potential of your home with a transformative, custom whole-house remodeling project. Whether you’re in Redwood City or throughout the surrounding Silicon Valley communities, Calwest Builders is ready to guide you from first ideas to final walkthrough.


  • What does a full home remodel cost in areas like Redwood City or Atherton?

    Costs can vary widely based on size, scope, and level of finishes. In Silicon Valley, a whole-home renovation often starts around the mid six figures and can reach $2M+ for expansive luxury projects with structural changes, premium materials, and extensive custom work. During our consultation and design phase, we develop a detailed scope and line-item estimate so you understand where every dollar is going. Our goal is to align your complete home makeover with both your vision and your investment comfort level.

  • How long does a whole-home renovation take?

    A custom whole-house remodeling project typically ranges from 6 to 12+ months once construction begins, depending on the size of the home, complexity of the work, and degree of customization. Permit timelines, structural reviews, and specialty items such as custom cabinetry or imported materials can add to the schedule. We provide a realistic timeline up front and update it as approvals and selections are finalized. Throughout the project, our team focuses on staying on schedule and communicating clearly about milestones.

  • Can we live in the house during a complete remodel?

    For down-to-the-studs whole-home remodeling, most clients choose to move out for safety, convenience, and speed of construction. In some cases, a phased approach may allow you to occupy certain parts of the house while other areas are under construction, but this depends heavily on the scope of work. We’ll walk you through options, including temporary relocation or short-term housing strategies, and help you weigh the trade-offs. Whatever approach you choose, we’ll plan the project to minimize disruption as much as possible.

  • Do you handle historic homes or older structures?

    Yes, we’re comfortable working with older Bay Area homes, from mid-century properties to more traditional houses that need significant updates. These projects often involve additional considerations such as structural retrofits, outdated wiring or plumbing, and potential surprises behind walls. We take a careful exploratory approach early, factoring in contingencies and coordinating with engineers or specialists when needed. The goal is to preserve character where it matters while bringing your home up to modern standards of safety, comfort, and performance.

  • Will my whole-home remodel be a good investment?

    A thoughtfully executed custom home remodel can significantly increase property value in high-demand Silicon Valley markets, especially when it modernizes layouts, upgrades kitchens and baths, and improves overall efficiency. Beyond resale, clients consistently tell us that the biggest “return” is how much more they enjoy living in their homes day to day. We’ll help you prioritize elements with strong ROI—such as premium kitchens, primary suites, and energy-efficient systems—so your budget is focused where it matters most. Our experience with luxury buyers in this region informs every recommendation we make.
