Frequently Asked Questions

How do I request urgent plumbing service in Larkspur?

Contact us about urgent issues such as burst pipes, slab leaks, and sewer backups in Larkspur, Greenbrae, and Baltimore Canyon. We’ll confirm availability when we speak with you. We’re licensed (CA #501853) and have served Marin since 1986.

Can you handle heating repairs in older Larkspur homes?

Absolutely. We routinely service and replace the aging wall furnaces, floor heaters, and undersized systems common in Heather Gardens and Baltimore Park, and we’ll advise whether repair or a modern upgrade makes more sense for your home.

Is air conditioning worth installing in Larkspur?

Many older Larkspur homes were built without it, but with warmer inland afternoons more homeowners are adding ductless mini-splits or central AC. We size and install systems that fit canyon homes and historic lots without overspending.

Why do drains back up in homes near Corte Madera Creek?

Low-lying areas near the creek and Greenbrae marsh sit on a high water table, and king tides plus winter rain overload older clay sewer lines and tree-root-prone drains. We can camera-inspect the line, clear blockages, and explain repair options.

When should an older Larkspur home be repiped?

Your home should most likely be repiped if you notice frequent leaks, low water pressure, or rust-colored water coming from your fixtures.

Can an old sewer line be repaired instead of completely replaced?

It will depend on the extent of the damage, but options like trenchless sewer repair and pipe-lining are good alternatives to a full line replacement. You can also only replace sections of the pipe if the entire sewer line is not damaged.

Why does my upstairs bathroom have lower water pressure?

Clogged or aging pipes, partially closed valves, or faulty pressure reducing valves could be the reason for this. Water will lose a bit of its pressure in upper levels because it is going against gravity, but the previous problems could worsen it.

Are mini-splits good for older homes without ductwork?

Mini-splits can be a great option for homes without ductwork since they do not require the installation of ducts! They also offer zoned heating and cooling, which can be great for multi-level or large homes.

Why are the temperatures so different between floors in my Larkspur home?

Uneven temperatures between floors can be a sign of air leaks through doors and windows, leaks in your ducts, blocked vents, or a system that is aging or not suitably sized to your home.
