Our Gate Repair Services in Tamalpais Valley
Post Repair
Post repair is the most common call we get in Tamalpais Valley, and for good reason. The valley’s original mid-century ranch and redwood-clad cottage homes were built with abundant local timber - beautiful redwood posts that have spent sixty years in ground contact under dense oak and redwood canopy. That persistent dampness, far more concentrated than in open communities like Corte Madera, causes ground-contact rot that hollows posts from the base up. We pull the old post, pour a proper concrete footing with drainage, and set a pressure-treated or steel post depending on your gate’s weight and your preference. A typical post repair in Tamalpais Valley runs $340-$580.
Rust Treatment & Hardware Replacement
Tamalpais Valley’s canyon geography channels marine fog from the Pacific through the Muir Woods corridor and holds it against the hillside well into midday. This gives the valley measurably higher humidity than nearby Mill Valley flats, and metal gate hardware pays the price. Springs, hinges, latches, and automatic operator components corrode faster here than virtually anywhere else in the county, often failing within 3-5 years without stainless or properly coated hardware. We strip rusted components, treat the metal, and install marine-grade or stainless-steel replacements that match the environment. Rust treatment with hardware replacement typically runs $180-$420 in Tamalpais Valley.
Gate Realignment
Steep, narrow hillside lots are the norm in Tamalpais Valley, and decades of uneven settling rattle gate frames out of square. Add tree-root heaving from massive coastal live oaks pushing surface roots under posts, cracking concrete footings and tilting posts 2-4 inches off plumb, and you’ve got a gate that drags, binds, or won’t latch. We diagnose whether the problem is the frame, the posts, or the terrain itself, then square and brace the gate or reset the posts as needed. Gate realignment in Tamalpais Valley typically costs $220-$480 depending on whether post work is involved.
Weld Repair
Iron and steel gate frames in Tamalpais Valley take stress from hillside movement and heavy redwood infill panels that swell and contract with the valley’s moisture cycles. We bring portable welding equipment to every job and repair cracked or broken frames on-site, matching the original weld profile and finish. Most weld repairs are completed in under two hours and cost $200-$380.

Common Gate Repair Problems We See in Tamalpais Valley Homes
- Redwood post rot at ground contact. The valley’s dense canopy keeps gates in near-constant shade and dampness even on sunny days elsewhere in Marin. Original redwood posts from the 1950s-1970s are often completely hollow at the base, concealed by intact wood above.
- Rust-seized hinges and latches. Canyon-trapped fog accelerates corrosion so aggressively that standard hardware can freeze solid within a few seasons. We replace with marine-grade stainless or hot-dip galvanized components.
- Gates racked out of square from hillside settling. Uneven terrain and decades of subtle ground movement twist rectangular gate frames into parallelograms that drag and won’t latch.
- Tree-root heaving tilting posts off plumb. Coastal live oaks and second-growth redwoods throughout the valley push massive surface roots under gate posts, cracking footings and tilting posts 2-4 inches - a pattern we’ve seen repeatedly in the same canyon neighborhoods.

FAQs - Gate Repair in Tamalpais Valley
Tamalpais Valley’s dense redwood and oak canopy traps persistent moisture and keeps gates in near-constant shade, while Corte Madera’s more open exposure allows faster drying. This concentrated dampness accelerates ground-contact rot in redwood posts by years compared to sunnier neighborhoods. If your post is soft at the base, call (833) 754-7503 for a free estimate - we can often diagnose the extent without disassembly.
Marine-grade stainless steel or hot-dip galvanized hardware with proper drainage clearances outlasts standard components by a factor of three in Tamalpais Valley’s humidity. We specify these on every replacement and avoid bare carbon steel entirely. Our technicians carry both in their trucks, so the upgrade happens on the first visit.
Yes, though the fix depends on whether the root can be safely cut or the post must be relocated. We recently replaced a post on a Shoreline Highway property where a coastal live oak had heaved the footing 3 inches off plumb - we cut the intrusive root, poured a new reinforced footing at proper depth, and realigned the gate in one trip. Call (833) 754-7503 and we’ll assess whether your post can be saved or needs replacement.
We do. Many Tamalpais Valley properties have detached workshops, guest cottages, or oversized estate entries with gates far heavier than standard residential units. We bring welding rigs, heavy-duty operators, and the structural hardware to match - no job is too small, and none too heavy for our equipment.
Most repairs are completed in 1-3 hours on a single visit. Post replacements and major realignments on steep lots may take half a day. We schedule with realistic timeframes and communicate if terrain or access extends the work. Call (833) 754-7503 to book - live person, no voicemail.
