Frequently Asked Questions
What areas near 94403 do you serve?
We cover all of 94403 plus surrounding San Mateo neighborhoods. If you are unsure whether your address is in our service area, call 719-403-0539 - if you are in or near San Mateo, the answer is almost certainly yes.
How fast can you get to my home in 94403?
We dispatch locally across San Mateo, so most 94403 calls get same-day service and true emergencies get priority dispatch around the clock. When you call 719-403-0539, the dispatcher gives you an honest arrival window based on where our nearest tech is - not a vague four-hour block.
My water bill jumped suddenly. What should I do?
A sudden spike usually means a hidden leak - often a toilet flapper, a slab leak, or a failing main line. Check your water meter with everything off: if it is still moving, you have a leak. Call 719-403-0539 and our 94403 leak detection crew will pinpoint it with acoustic and thermal equipment before it does more damage.
Should I repair or replace my water heater?
It depends on age and condition. Tanks over 10-12 years old with rust, rumbling, or repeated repairs are usually better replaced - a new unit pays back in efficiency and reliability. Our 94403 techs give you both numbers, repair and replacement, so the decision is yours. Call 719-403-0539 for an honest assessment.
Do you install water softeners and filtration in 94403?
Yes - whole-house softeners, under-sink filters, and full filtration setups. We start with a water test at your 94403 home, recommend the right system for your water quality, and install it cleanly with proper drainage and shutoffs.
