Custom redwood decks built for Peninsula hillside terrain and coastal conditions — Con-Heart and Clear Heart material, proper pier engineering, and thirty years of experience on these lots.
Redwood decking on the Peninsula is a craft decision as much as a material one. Con-Heart and Clear Heart grades give you a stable, clear-faced board that ages gracefully in coastal air — when the substructure is engineered correctly underneath it.
Redwood has been the deck material of choice on the Peninsula for decades. It is native to Northern California, dimensionally stable in coastal humidity, and has a natural warmth that composite products approach but do not replicate. Con-Heart grade — clear of knots, cut from the heartwood — is what we specify for deck surfaces where appearance and structural consistency matter. Clear Heart is available where a premium clear face is the priority. We engineer the substructure for your specific lot: pier depth and spacing calculated for the grade, soil, and load. Hillside builds, wrap-around configurations, elevated entries — these are the conditions we work in most on the Peninsula.
The ledger connection is where most Peninsula decks eventually develop problems. The board that attaches the deck frame to the house sits against a wall that gets wet. Without correct flashing detail, water migrates behind the ledger and into the framing — silently, for years — until it becomes a structural repair. We flash every ledger connection correctly and document it for the inspection. All fasteners and hardware are hot-dipped galvanized or stainless — post bases, joist hangers, beam connectors, and deck screws are all specified for the coastal environment. Standard hardware corrodes fast in salt air and we do not use it. If an existing redwood deck is showing signs of ledger or structural deterioration, our rot and structural repair work starts with a thorough assessment before any scope is written.
Redwood pairs naturally with a range of railing and stair options. Matching redwood railings give a cohesive natural look; iron railing systems add a more architectural finish and integrate well with our ironwork and gates work elsewhere on the property. Stairs and landings are designed as part of the deck from the start — not added on after the frame is in. For properties where low maintenance is the priority over natural wood character, see our Trex and composite decking page for a direct comparison of both approaches.
Two strong options — different in character, different in what they ask of you. The right choice depends on your property, how you use the space, and what matters most to you.

Redwood decks on Peninsula hillside lots require careful pier engineering. The grade determines stringer and beam sizing, the soil determines footing depth and diameter, and the deck height above grade determines the bracing required. We calculate all of this at the design stage — not after the piers are poured. Wrap-around configurations, multi-level decks, and elevated entries are the builds we do most on the Peninsula.
Redwood can be left to weather to a natural silver-gray patina, sealed clear to preserve the warm honey tone, or finished with a penetrating stain in a range of colors. The right approach depends on your exposure, your preference, and how much you want to maintain the surface over time. We discuss finish options at every estimate and can point to examples of each approach on comparable Peninsula properties.
All fasteners and hardware in our redwood builds are hot-dipped galvanized or stainless. Standard hardware corrodes fast in coastal air — we do not use it. Post bases, joist hangers, beam connectors, and deck screws are all specified for the coastal environment. This is one of the details that separates a deck that holds for decades from one that starts showing hardware rust in two seasons.
Composite decking was engineered specifically for the conditions that challenge wood — moisture, UV, and temperature cycling. On the Peninsula, where coastal fog and salt air accelerate the weathering of untreated surfaces, composite holds up without the maintenance routine that redwood requires. The surface does not check, split, or absorb moisture the way wood does, and the color is locked into the material rather than applied on top of it.
We are a Trex Gold Partner contractor — which means we install the full product line, maintain current installation certifications, and are familiar with every profile, color, and railing system in the Trex catalog. We can walk you through the options at your estimate and show you samples from comparable Peninsula builds. Other composite brands are available where the project calls for them. See our dedicated Trex and composite decking page for full detail.
Composite decking requires a properly built substructure — the boards themselves are only as good as what they are fastened to. We build subframes to manufacturer spec, with correct joist spacing, proper ventilation beneath the deck surface, and hardware rated for the composite product installed. Hidden fastener systems keep the deck surface clean and eliminate exposed screw heads. On hillside lots we engineer the pier layout and post sizing for the specific grade and load.
Composite decking is available in a wide range of colors, surface textures, and board profiles — from grooved hidden-fastener boards to solid-edge capped profiles. Railing systems, fascia boards, and post wraps in matching or complementary materials complete the build. We work through the options at your estimate based on your home's exterior and what fits the Peninsula context.
Composite decking is low-maintenance — not no-maintenance. The surface benefits from periodic cleaning to remove salt residue, organic debris, and the biofilm that can build up in shaded coastal environments. Most composite manufacturers recommend an annual wash with a composite-safe cleaner and a soft brush. Avoid pressure washing at high PSI — it can damage the surface texture of some composite profiles. Beyond cleaning, composite decks require no staining, sealing, or sanding.
Salt air affects composite decking differently than it affects wood — the boards themselves are largely unaffected, but hardware and substructure components still need to be coastal-rated. We specify galvanized and stainless hardware throughout, including hidden fasteners, joist hangers, and post hardware. A composite deck surface on a substandard substructure is still a problem — the whole system needs to be built for the environment.
A properly finished redwood deck in the Peninsula climate needs attention on a schedule that depends on the finish type and the exposure. Clear-sealed surfaces benefit from reapplication every two to three seasons in high-exposure locations. Stained surfaces can go longer between treatments. Natural weathered redwood requires no finish maintenance but will gray out fully over time. The key is starting with the right finish for your situation and maintaining it before the surface opens up to moisture intrusion rather than after. Our staining and sealing service handles this work on decks we have built and decks we have not.
Whether composite or redwood, all decks benefit from a periodic inspection of the substructure — checking posts at grade for moisture intrusion, looking at ledger connections, and verifying that fasteners and connectors are performing. On Peninsula hillside builds we also check that drainage around footings has not changed. Catching small issues early keeps them from becoming structural ones. We are available for inspection and maintenance work on decks we have built and decks we have not.
What we hear most before the estimate, during the build, and after.
We build in clear heart redwood, cedar, Trex composite, and other leading composite and PVC decking brands. Material choice depends on your budget, maintenance tolerance, sun exposure, and aesthetic. We walk you through the trade-offs at the estimate.
Almost always, yes. Any deck attached to the house or above a certain height — typically 18 to 30 inches depending on the city — requires a building permit. We pull permits and manage the inspection process as part of every deck project.
A well-built redwood deck lasts 15–25 years with periodic maintenance — cleaning, sealing, and board replacement over time. Quality composite decking like Trex is warrantied for 25–30 years and requires almost no maintenance beyond occasional cleaning. The right choice depends on how you want to spend your time and money long-term.
Yes. We assess the structure first — framing, ledger connection, and posts are the critical elements. If the structure is sound, we can replace just the decking surface and railing. If the frame has deteriorated, a full rebuild is usually safer and more cost-effective than piecemeal repair.
Trex is the category leader in composite decking — made from 95% recycled material, available in a wide range of colors and finishes, and backed by a strong warranty. Other quality brands include TimberTech and Fiberon. We install several brands and can help you compare options for your specific project and budget.
A typical residential deck takes one to two weeks from permit approval to completion. Permit timelines vary by city — some Peninsula cities turn permits in a few days, others take longer. We give you a realistic timeline at the estimate based on your city’s current processing times.
Possibly, but it requires engineering review. A filled hot tub adds 80–100 pounds per square foot — far beyond standard deck load assumptions. We assess the existing or planned structure and coordinate with a licensed engineer when required. Do not place a hot tub on an existing deck without having the structure evaluated first.
