The 2025 Cost vs. Value Report puts fiber cement siding replacement at roughly a 114% cost recoup at resale — about $24,420 in added home value — with vinyl at about 97%. On the coast, where salt air and marine moisture accelerate wear on cheaper materials faster than in inland markets, the siding choice affects both how long the exterior lasts and what a buyer's inspector finds when the home eventually sells.

Genuine before-and-after results from recent GVD siding projects near Half Moon Bay.
Cost per square foot depends on material, home size, and how much of the existing wall assembly needs repair once old siding comes off. Fiber cement costs the most per square foot but returns the highest resale figure and the longest lifespan. Vinyl costs the least upfront and still returns strong value, particularly on smaller homes or rental properties where minimizing spend matters more than maximizing resale. GVD quotes are free, written, and fixed-scope: you see the total price and exactly what's included before you sign anything.
Fiber cement (James Hardie) carries a Class A fire rating on its own — the most common Class A siding choice GVD installs and the most resistant to warping, rot, hail, and pests. Its factory ColorPlus finish holds color for decades, and it lasts 30 to 50 years. It is the heaviest material and the slowest to install.
Engineered wood (LP SmartSide) is treated and wax-sealed against moisture, with a real-wood grain look. It lasts 20 to 30 years, is lighter than fiber cement, and installs faster. It is combustible and does not provide the same fire resistance as fiber cement, so it is not the right pick for west-facing walls that take direct wind-driven rain here. On its own it is combustible, but LP SmartSide is CAL FIRE-listed for California WUI zones when installed as part of a qualifying fire-rated wall assembly — something GVD builds where code calls for it.
Insulated vinyl costs the least per square foot and suits tight budgets or investment properties. It is also combustible and does not provide the same fire resistance as fiber cement, and it has the least resistance to moisture absorption of the three.
Because Half Moon Bay's marine layer keeps humidity and fog sitting on north and west walls for much of the year, GVD recommends fiber cement for this city. It resists the rot and moisture swelling that shorten the life of more absorbent siding materials in this climate, which matters most on the shaded, fog-facing sides of a house. GVD carries James Hardie, CertainTeed, Prodigy, and LP product lines to match whichever material fits the home and budget.
GVD does both, and coastal moisture drives the decision. When the existing layer is sound, flat, and dry — and code and the siding manufacturer's specs allow it — installing over it is a common, legitimate option. GVD removes old siding whenever the sheathing shows rot, the existing layer is uneven, or code or the manufacturer requires removal. Stripping the wall down lets the crew inspect and repair the sheathing underneath and install a new weather-resistive barrier, both of which matter in a coastal climate where moisture behind old siding can cause hidden damage. GVD evaluates each wall during the free estimate and recommends overlay or removal case by case — and either route, installed to manufacturer specifications, keeps material warranties valid.
Half Moon Bay's exterior walls deal with three specific stresses: salt air that corrodes exterior metal and fasteners over time, marine-layer moisture that drives mildew growth and premature paint failure, and wind-driven rain that hits west-facing walls hard during winter storms. Corrosion-resistant fastener selection and proper flashing at every seam matter more here than in drier inland cities. Where a property sits closer to wildland vegetation or falls under stricter fire-exposure guidance from the city or county, fiber cement is the only one of the three materials on this page that meets Class A fire rating, and GVD recommends it in those locations without exception.
GVD handles any required permits through the City of Half Moon Bay or San Mateo County depending on the property's location before work begins. Most homes are fully re-sided in one to two weeks. A single-story home around 1,500 square feet typically takes a few days to a week. Two-story homes, multi-color designs, and any sheathing repairs found during removal extend the schedule, and fiber cement takes longer to cut and hang than vinyl due to its weight and density. Crews protect landscaping, clean the site daily, and the proposal includes firm start and finish dates before work begins.
Every GVD project includes a written workmanship warranty in addition to the manufacturer's material warranty. As a James Hardie Elite Contractor and LP SmartSide Master Contractor, GVD's certification status is what keeps those manufacturer material warranties valid for the homeowner. Skipping a certified installer can void that coverage even if the material itself is sound.
GVD is a local, family-owned contractor with its own in-house installation crews, meaning the same team stays on your project from start to finish. The company holds a 4.9/5 rating across 921+ GuildQuality and Google reviews and an A+ BBB rating. Before any work starts, GVD puts the full scope and a firm total price in writing — free, and with no obligation.

We bring the same crews, materials, and workmanship to every community around Half Moon Bay.
For most Half Moon Bay properties, yes, particularly on north and west-facing walls exposed to fog and wind-driven rain. Its resistance to moisture swelling and rot outlasts engineered wood and vinyl in this climate, and it carries a Class A fire rating on its own — the most common Class A siding choice GVD installs if fire exposure is also a concern.
Either, depending on what inspection shows. If the existing siding is sound, flat, and dry and code and manufacturer specs allow it, installing over it is often a good option. GVD removes existing siding whenever the sheathing shows rot, the surface is uneven, or code requires it, since removal allows a full inspection and repair of the sheathing and a fresh weather-resistive barrier. The recommendation comes with your free estimate.
Most homes finish in one to two weeks. A single-story home around 1,500 square feet often takes a few days to a week, while two-story homes, multiple colors, or sheathing repairs add time. Your proposal will include specific start and finish dates.
