Corte Madera repairs on bay fill and Christmas Tree Hill
Houses in Marina Village and Mariner Cove stand on 1950s bay fill that has settled as much as four feet in places, so doors bind, trim pulls apart and garages flood on high tides. On the other side of town, Christmas Tree Hill's old summer cottages climb narrow zigzag streets and stairways.

When the bay mud under a Marina Village or Mariner Cove house compresses unevenly, door frames go out of square. Doors rub at a top corner, latches miss their strike plates and sliding doors drag. A handyman can shim hinges, move strike plates, plane and reseal door edges and adjust sliders. Because settlement continues, this can become a repeat job every few years. If doors and windows throughout the house are racking badly, get an engineer's opinion first. More about door and window repair
Settlement cracks and flooded garage walls
Settling houses develop diagonal cracks running from the corners of doors and windows, and a quick patch over ongoing movement tends to reopen. Taping the crack properly and finishing it flat holds up better. Garages here face a second problem: the town reports that backyards, garages and driveways in the bayside neighborhoods flood during high tides and storms, soaking the bottom of garage walls. After drying, a handyman can cut out wet drywall above the waterline, replace it and reinstall trim. More about drywall and plaster repair
Garage door and threshold seals
Tidal flooding in the bayside neighborhoods often starts as water creeping under a garage door or a ground-level back door. Replacing a flattened garage door bottom seal, adding a threshold seal and closing gaps where the slab meets the wall will not stop a real flood, but it keeps out splash, wind-blown rain and the shallow water of smaller tides. It is worth doing before the winter king tides arrive. More about weatherstripping, caulking and sealing
Stairs and railings on Christmas Tree Hill
The hill's developer built public stairs so residents could walk down to the old Corte Madera train station, now Menke Park, and the neighborhood still runs on steps: zigzag roads, steep lots and wooden stairs from street to front door, often under redwoods. Treads soften, handrails loosen and landings rot where water sits on them. A handyman can replace treads and rail sections and re-anchor posts. Stairs with rotten stringers or supports need a licensed contractor. More about carpentry, shelves and trim
Cracked tile and lifting planks
As bayside houses settle, floors pick up slopes and small humps, tiles crack along a line and laminate or engineered planks open gaps or buckle, especially after water comes in from a flooded garage. A handyman can replace cracked tiles, swap damaged planks and reset thresholds and transitions that have lifted. Leveling a floor that has sloped is another matter: that involves the foundation and needs a licensed contractor. More about flooring repair
How the houses here are built
More than 500 homes in the Marina Village and Mariner Cove tracts on filled baylands, plus Madera Gardens nearby; and on Christmas Tree Hill, summer cottages from the 1890s onward that became year-round homes, with houses reaching the top of the hill by the 1950s.
The bayside tracts rest on bay mud that compresses under houses and streets and is still settling at up to 1.4 inches per decade, which pulls door frames, floors and drain lines out of line. On the hill, early lots were as small as 1,250 square feet on steep ground, reached by narrow roads and stairs rather than driveways.
Storms that arrive with a king tide push bay water into bayside yards and garages; in January 2026 Highway 101 through town flooded about 2.5 feet deep.

Settlement and tides in the bayside tracts
The town's climate adaptation plan says Marina Village and Mariner Cove hold more than 500 homes built on filled baylands in the 1950s, that parts have settled up to four feet since construction, and that settlement continues at up to 1.4 inches per decade. An earthen levee separates Marina Village from the marsh to the north, but pump stations can be overwhelmed when storms meet high tides. Madera Gardens, Marina Village and Mariner Cove saw widespread flood damage in 1982 and 1998.
Getting around Christmas Tree Hill
Christmas Tree Hill is one of the town's oldest sections. Small lots sold in the 1890s became summer retreats for San Franciscans, and the name comes from the 1920s, when colored bulbs in the street lamps traced a tree shape along the zigzag roads. Those roads are still narrow and steep, with stairs linking down to Menke Park. Since 1984 the town has set minimum lot sizes of 20,000 square feet on the upper hill and 7,500 on the lower hill. Expect limited parking.

Questions from Corte Madera homeowners
Our Mariner Cove door was adjusted last year and sticks again. Why?
Because the ground is still moving. The town puts settlement in the bayside neighborhoods at up to 1.4 inches per decade, and it is rarely even, so a door fitted today can drift out of square again. Shimming hinges and moving the strike plate is a normal repeat repair here. If several doors and windows shift at once, or cracks grow quickly, have an engineer look.
Can a handyman keep tidal water out of our Marina Village garage?
Not completely. Seals under the garage door and at thresholds keep out splash and shallow water, but the town's own plan says garages and driveways there flood in high tides and storms, and the real protection comes from the levee and pump stations. What a handyman can do is fit seals, raise storage onto wall-mounted shelving and replace drywall and trim after water gets in.
Is it hard to get repair work done on Christmas Tree Hill?
It takes planning. Streets on the hill are narrow and zigzag up steep ground, parking is scarce, and some houses are reached only by stairs. Tell us whether a vehicle can stop near your door, how many steps lead to the entry and what has to be carried in, so the job is booked with enough time and help.
Are cracked floor tiles in a bayside house a handyman job?
Replacing the tiles is. The catch is that settlement under these houses continues, so a crack that runs in a line across a room may return. If the floor also slopes noticeably, or doors nearby have started binding, the cause is below the floor, and a licensed contractor or engineer should assess it before new tiles go down.
