Gutter Installation in Mill Valley

Mill Valley is one of the hardest places in Marin to keep a gutter working. Redwoods shade much of town, and they drop small, flat sprays of needles in every season. Under the trees, debris stays damp, moss grows on the north side of roofs, and a gutter that looked clean in October can be packed again by January. Then there are the slopes. Plenty of houses here sit on lots so steep that the street side is one story and the downhill side is three, which makes every gutter job a ladder and access problem before it's a gutter problem. Water from those roofs also has a long way to fall and a hillside to run down once it lands. And on the narrow lanes up the canyons, just getting ladders and material to the house takes planning.

We take all of that into account on a Mill Valley job. Most homes under redwoods get the most from metal mesh gutter guards, and hillside houses need a real plan for where the downspouts empty. We'll walk the property with you, top to bottom, and put it all in a free written estimate.

Redwood Debris and Year-Round Cleaning

Redwoods are different from oaks. An oak drops its leaves mostly in fall and is done. A redwood sheds a steady stream of small needle sprays and cone bits through every season, and on foggy summer days, moisture condensing on the branches drips down onto roofs and keeps that debris wet. Wet redwood debris packs tight and holds water, which is why gutters under these trees clog faster than people expect and grow moss so readily. For homes with redwoods overhead, one fall cleaning usually isn't enough. Two or three cleanings a year, or fine mesh guards that keep the bulk of it out, makes the difference between gutters that drain and gutters that overflow every storm. Our gutter cleaning page explains what each visit covers. Guards don't end the work entirely, since needles still settle on top, but they turn a messy job into a quick brush-off once or twice a year. Homeowners in the wooded canyons of Larkspur and along the hills of Tiburon run into the same problem.

Steep Lots and Tall Downhill Walls

On a steep Mill Valley lot, the gutter itself is only half the job. A roof on the downhill side of a house can sit 25 or 30 feet above the ground below, which takes proper ladders, staging and care to work on safely. Once water reaches the downspout, it can't just be dumped at the base of the wall, where it will run down the slope, cut channels in the soil and push against retaining walls and foundation footings. We plan downspout locations so the water has a safe path, whether that's an extension onto a stable spot, an underground line to a better outlet, or splitting the flow so no single downspout carries too much. Our downspouts and drainage page goes into the options. We'll also point out anything that needs a drainage specialist rather than a gutter crew, such as a failing retaining wall. The same planning applies on the hillside streets of Sausalito, where many homes sit just as steeply above the water.
