Tell us what's happening - is it no hot water, a leak, a noise? We'll send the right plumber with the right parts.
On-site diagnosis of your tank or tankless system - full inspection, no trainees, no handymen on the truck.
You get repair and (if relevant) replacement options - your choice, your price in writing. We repair first, replace only if genuinely uneconomic.
Water heater work attracts the operators who'd rather sell you a new tank than fix the one you have. Here's how Diamond is different.
Same-day service in most cases. Fully-stocked trucks mean most repairs are one-visit, not a return trip next week.
A leaking tank can destroy floors, drywall, and framing fast. We contain the leak and fix the cause - not just the symptom.
If repair makes sense, we'll say so. If your tank is past it, we'll tell you why - with the numbers. No pressure.
