How much do home services cost in San Mateo?

NorTech uses pricing set by local pros, so you see the full price before you book in ZIP 94401 and across San Mateo. Each local pro sets their own price, and because the rate is set up front there are no surprise hourly charges.

Are the providers licensed, insured, and background-checked?

Every job goes to a background-checked and insured independent provider. NorTech keeps work within California's $1,000 handyman exemption, and for larger projects that exceed it, jobs are bid on by NorTech-verified licensed contractors so the right scope is handled correctly.

Can you help me get my San Mateo home ready before the rainy season?

Yes. Pre-rainy-season exterior work is one of the most common reasons people book here, including stucco sealing on older Spanish colonial homes, gutter cleaning, and caulking and weatherproofing to keep Peninsula moisture out.
