"What's your response time for emergencies?"
The short answer: faster than anyone else you've called. We run one truck because one truck means no dispatch queue, no junior tech sent ahead, and no excuses about crew scheduling. When unit 12A loses hot water on a Tuesday morning, you get a callback in under 20 minutes and a wrench on the problem within the hour.
Kitchen faucet replacement · Richmond District · Completed same-day
"We manage 67 units across the Outer Sunset and Wrench has never once missed a same-day callback. That alone is worth the retainer."
Marcus Webb
Director of Operations · Avery Property Group, San Francisco
"Can you handle a punch list of thirty items across three properties in one week?"
Yes — and we have. The key is the way the week is structured: properties are batched by neighborhood, punch lists are pre-triaged by trade type, and materials are staged the night before. You send the list Sunday. We send progress photos by Wednesday. Final sign-off by Friday.

"What does a long-term maintenance arrangement actually look like?"
Three structures, zero ambiguity. You choose the level of commitment that fits your portfolio size. No locked-in annual contracts — any arrangement can be adjusted quarterly as your property count changes.
