At a glance
Each shower problem has a short list of likely causes.
| What you notice | Likely cause | Usual fix |
|---|---|---|
| Drip from the head after shutoff | Worn cartridge or seals | Cartridge or seal kit |
| Water too hot or too cold, or swinging | Pressure balance spool or mixing cartridge | Cartridge replacement |
| Handle stiff or loose | Worn stem, cartridge, or trim | Cartridge or trim repair |
| Weak or uneven spray | Clogged head or flow restrictor | Clean or replace the head |
| Tub spout runs with shower on | Worn diverter | Diverter or spout replacement |
| Stain on the ceiling below | Leak at valve, pipe, or drain | Locate before opening |
If you see a stain on the ceiling or wall below a bathroom, stop using that shower until we look. That pattern can mean a leak inside the wall or at the drain.
Some shower leaks never show up at the head. Watch for:
Those signs point to the valve body, a pipe joint behind the wall, the drain, or failed grout and caulk. Each needs a different fix, so we narrow it down before opening anything. Sometimes the answer is resealing the tub edge. Sometimes it is a valve repair through the access panel.
We keep the valve you have when we can. Repair is the right call when:
Replacement deserves a conversation when:
Replacing a valve usually means opening the wall behind it. Before any work that opens a wall or replaces pipe, we confirm permit requirements with the City. You get that answer up front.
About 40 percent of Redwood City’s housing units were built before 1960, and the 1950s is the single largest decade, according to Census estimates. Older bathrooms can hold valves from brands that have changed hands or stopped making parts.
When we open one of those valves, we identify the brand and model before quoting. If a matching cartridge exists, we fit it. If it does not, we explain the replacement options and what each would involve, so you choose with the facts in hand.
A dripping or sputtering head is sometimes the whole problem. We clean or replace it, and we check the flow restrictor inside.
The City’s fixture handout lists the current limit for a single showerhead as 1.8 gpm at 80 psi. When we fit a new head, we choose one that meets that limit. Homes finaled before 1994 that undergo permitted alterations may also need older fixtures replaced, and we confirm with the City when your work is part of a permitted project.
When a leak is hidden in the wall or under the floor, our leak detection service in Redwood City finds it before anything is opened. And if your faucets are dripping too, see our faucet repair in Redwood City.

Redwood City water is soft. Why does my shower still drip?
Soft water means little scale, but seals and cartridges still wear with every use. Over years the rubber hardens and stops sealing. A drip after shutoff usually means it is time for a new cartridge and seals.
Why do I see white specks on my showerhead in Redwood City?
Hardness ranged from 8.1 to 112 ppm in 2025. When supply runs toward the harder end, light mineral deposits can form where water sprays. Soaking or replacing the head usually solves it.
Can you repair an original shower valve in an older Redwood City home?
Often, yes, if parts for that valve are still made. We identify the brand before quoting. If parts are gone, we explain replacement options.
Do I need a permit to fix my shower in Redwood City?
It depends on the work. We confirm permit requirements with the City before any job that opens a wall or replaces pipe.
Does my home’s water come from the City or Cal Water?
Most of Redwood City is served by the City, and portions are served by Cal Water’s Bear Gulch District. In 2025 both supplies came from the San Francisco Public Utilities Commission. Your water bill shows your supplier.
Will a new showerhead lower my water pressure?
A new head meets the current 1.8 gpm limit listed by the City, so it uses less water than many older heads. Spray pattern matters as much as flow, and we help you pick one that feels right.
Book shower repair in Redwood City and we will find the worn part, fix it, and test it hot and cold before we leave.
You have to do it right for the first time in the first installation of your new shower or shower part. If a shower is not correctly mounted, the problems it creates may be more than just uncomfortable. A wrongly installed shower can leak or flood your house, causing severe water damage to neighboring areas. Furthermore, if a shower is not appropriately installed for the first time, it may be expensive to repair in the future. Trusted plumbers must install a shower to be reliable from day One to year 10. Works Plumbing has a plumbing team to equip the perfect shower to suit your needs. We Install the Following Shower Components: Stand-alone showers Whirlpool tubs Hot tubs Stand bathtub Walk-in tubs

A look at real Works jobs around the Peninsula.
Shower repair in Redwood City, CA starts with what comes out of the pipe. The City’s 2025 Annual Water Quality Report put hardness, measured as calcium carbonate, at 8.1 to 112 ppm in 2025, with an average of 62 ppm. Cal Water’s published scale calls water under 75 ppm soft, so the average Redwood City tap sits on the soft side.
That shapes how a shower wears here. In hard-water towns, mineral scale builds inside the valve until the cartridge seizes or the head clogs. In Redwood City, that is the exception. Most drips and temperature problems we see come from rubber and plastic parts that wear with use: O-rings, cartridge seals, and pressure balance spools.
The range still matters. A reading of 8.1 ppm and a reading of 112 ppm are very different waters, and the top of that range is no longer soft by the same scale. When supply runs toward the harder end, light white deposits can form on showerhead nozzles and around the diverter.
So our diagnosis follows the water:
