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.

What does it cost to book second-story addition in San Mateo?

Pricing is up-front and shown before you commit — enter your San Mateo ZIP — Baywood, Hayward Park and every nearby neighborhood are covered, pick Second-Story Addition, and the price is right there. Your card is held for the price at booking and only charged once the job is done.

Is second-story addition in San Mateo backed by a warranty?

Yes. Your pro backs every San Mateo job with a workmanship warranty of at least 30 days on general repairs and at least 90 days on tile, flooring, doors, and windows, and your pro may offer more. If covered work isn't right inside that window, your pro makes it right at no charge.
