Most installation calls start the same way. Something is going in that was not there before: a second sink, a tub where a shower used to be, a washer hookup in a garage, a gas stove that needs a proper connection. The plumbing behind the wall decides how easy that is, so we begin by looking at what you already have.
Installation is different from repair because you control the timing. That gives you room to decide where lines run, what shutoffs you want, and which fixtures are worth buying before the walls close up.
What we install
The work falls into a few groups, and most jobs touch more than one of them.
Fixtures and faucets
Sinks, vanities, tubs, shower valves, and kitchen or bath faucets. A new fixture on an existing rough-in is a short job. A fixture in a new spot needs new supply and drain runs, which is where the real planning happens.
Appliance hookups
Washers, dishwashers, ice makers, water softeners, and similar equipment that needs a supply line, a drain, and often a shutoff you can reach without moving the machine.
New and moved lines
Water and drain lines for additions, converted garages, new bathrooms, and kitchen remodels. We route around framing, size the pipe for the fixtures it serves, and set the vent so the drain actually flows.
Tub and shower installation
Tub swaps, shower pans, and valve changes. The valve body and the drain are the parts you cannot fix later without opening the wall, so we settle them first.
Gas connections
Stoves, dryers, barbecues, and similar appliances. Gas work gets extra care and a leak check before we leave.
If you smell gas at any point, leave the building and call 911 and your gas utility before you call us.
How an installation job runs
Phone scope
You tell us what is going in, where, and what is already there. We ask about the age of the house, what the walls are made of, and whether a remodel or permit is already in motion.
Site check
We look at the shutoffs, the existing supply and drain lines, venting, and access. This is where most surprises show up, so we write down anything that changes the plan.
Price and permit plan
You get a clear price before work starts. If the job needs a permit, we say so up front and explain who pulls it and what the inspector will look at.
Install and test
We rough in, set fixtures, pressure test supply lines, and run every drain. Gas lines get a leak check.
Walkthrough
We show you the new shutoffs, label what we can, and leave the work area clean.
Permits and who is allowed to do the work
Plumbing work in Millbrae generally falls under city permit rules, and the Millbrae Building Division handles plumbing permits. Whether a particular job needs one depends on its scope, so permits may apply and we tell you what we see once we know what you are installing.
Hiring matters here too. The California Contractors State License Board lists C-36 as the plumbing classification, and you can look up any contractor's licence on the CSLB site before you sign. The state's small-job exemption, now $1,000, does not cover work that needs a permit, so a permitted bathroom or remodel is not something to hand to an unlicensed helper.
Millbrae specifics for installation jobs
Millbrae's housing stock grew fast in the 1950s. Census counts show dwelling units rising from about 2,800 in 1950 to about 4,800 in 1960, so a large share of local houses were built in that era. If your remodel opens a wall in one of them, expect to meet original supply and drain lines, and plan the new work to tie into them cleanly.
The sewer side matters too. Under Millbrae's sewer ordinance, a building permit that adds plumbing fixtures or alters more than 25 percent of the building area triggers a camera inspection of the sewer lateral by a licensed plumber or sewer contractor. A lateral that fails on roots, loose joints, or missing cleanouts has to be fixed within 90 days, so adding a bathroom can add a lateral repair to the schedule.
Some qualifying remodels also require a sewer backwater valve and a relief device on the lateral. That is a code item, not an upsell, and it is far cheaper to place it while the work is already open. Dig-in jobs outside the house, like a new yard line, need a USA North 811 ticket with at least two working days of notice before the shovel goes in.
Installing new versus fixing what you have
| Situation | Better move | Why |
|---|---|---|
| Old faucet drips, valve is sound | Repair | A cartridge or seat swap costs far less than new hardware |
| Valve or supply line is corroded | Install new | Fresh shutoffs are the cheapest insurance in the cabinet |
| Moving a fixture across the room | New lines | Drains need slope and a vent, so location limits the layout |
| Adding a second bath | Full install plan | Triggers permit review and possibly a lateral check |
| Appliance has no shutoff behind it | Install a valve | You will want it the first time a hose fails |
The pattern is simple. If the fixture is the problem, we swap the fixture. If the pipe behind it is the problem, we fix the pipe once instead of dressing it up with a new faucet.
What shapes the price of an installation
What drives installation cost
Every install is priced from scope, so the number you get on the phone comes from what is behind the wall and what is being added.
Fixture and material choice
a builder-grade faucet and a custom shower valve are different jobs with different parts.
Access
open framing is simple, finished tile and drywall mean cutting and patching.
Distance to existing lines
the farther the new fixture is from supply, drain, and vent, the more pipe goes in.
Permit and inspection
permitted work adds a step that has to be scheduled and passed.
Hidden conditions
corroded valves or undersized drains found at opening can change the plan.
Call the 24/7 line for a clear price before work starts. Your homeowner policy rarely pays for planned upgrades, so we separate repair work from install work on the paperwork.
Have a remodel or a new fixture on the calendar?
Call and tell us what is going in. We will talk through the scope, flag anything that needs a permit, and give you a clear price.
Work that often goes along with an install
Many installs start with a repair that turned into a plan. A toilet that keeps running might be better replaced, and our toilet repair and installation page covers that choice in detail. Faucets and shutoff valves are often the first thing swapped during a bathroom refresh, and faucet and fixture repair handles the cases where the old hardware can stay.
If the walls are open and the supply pipe looks tired, that is the best moment to talk about repiping an older house rather than patching around it. We also work in Burlingame next door, and our Burlingame plumbing page lists what we cover there. For the full list of towns, see the service area.
Questions about plumbing installation
Usually yes. Bring the model number to the call so we can check the rough-in and the supply connections. We cannot judge a fixture's internal parts, so if it turns out to be the wrong fit, we will say so before cutting anything.
Permits may apply, and the Millbrae Building Division handles plumbing permits. Adding fixtures also triggers a sewer lateral camera inspection under the city sewer ordinance, so we plan that into the schedule from the start.
Look up the contractor on the CSLB website. C-36 is the plumbing classification. The state's $1,000 minor-work exemption does not cover jobs that need a permit, so permitted installs need a licensed contractor.
Often yes, but the drain needs slope and a vent, so the new spot has to work with the framing and the floor below. We check access first and tell you what the move would involve before you commit.
Yes, we make gas connections and leak test them. If you smell gas at any time, leave the building and call 911 and your gas utility first, then call us once everyone is safe.
A single fixture on an existing rough-in is often a same-day job. Moved lines, tubs, and showers take longer, and permitted work includes an inspection. We give you a realistic schedule on the phone.
We stop, show you, and explain the options before adding anything to the price. Corroded valves and undersized drains are the usual finds, and many are inexpensive to fix while the wall is already open.
The call line runs 24/7, so you can book an installation at whatever hour you finally get around to it.
