House rewiring and knob and tube replacement in Colma, California

If your Colma home has two-prong outlets, no ground, warm switch plates or an insurance company asking questions, the wiring is the issue. We rewire in planned phases so the house stays livable, and we cut access holes where they patch cleanly instead of wherever is fastest.

Whole House Rewiring across Colma

We cover all of Colma, from downtown out to the newer subdivisions on the edge of town, plus the neighboring communities of South San Francisco, Daly City and Brisbane.

Colma sits in San Mateo County, and the electrical work here reflects that mix: older housing stock that needs grounding, capacity and device upgrades, alongside newer construction that simply needs more circuits than it was built with. Crews route through the Peninsula daily, so travel time to a call in Colma is short.

Recent Colma feedback

We rewired in stages so we could keep living here. They planned the access holes where the patcher could actually fix them, which I did not expect.

Ellen and Ray M.Colma, CA

Breaker had been tripping for months. They found an overloaded shared circuit and put the microwave on its own. Has not tripped since.

Omar D.Colma, CA

Our restaurant cannot close, so they did the panel work overnight. Walked in the next morning to everything working and the floor cleaner than we left it.

Whole House Rewiring in Colma — questions we get asked

Is aluminum wiring dangerous?

Aluminum branch wiring from the 1960s and 70s is not inherently unusable, but its connections loosen and overheat over time. Remediation with listed connectors or replacement resolves it.

How do I know if I have knob and tube wiring?

Look in the attic or basement for individual wires running through white ceramic knobs and tubes. Two-prong outlets throughout and a fuse box are strong supporting signs.

Do I have to move out during a rewire?

Usually not. We work in phases and keep power on to the areas you are using. Larger San Mateo County projects sometimes have a day or two where it is easier to be elsewhere.

Will you patch the drywall?

We cut planned, patch-ready access and coordinate closely with your patcher or painter. Ask and we will quote the rewire with patching included.

How much does it cost to rewire a house in Colma?

Whole-home rewires in Colma are priced by square footage, circuit count and access — a single-story home with an accessible attic and crawlspace costs far less than a two-story plaster home. We walk it, then give one firm number.
