What breaks in a building, and what we do about it.

Property managers call us for the work that keeps units rentable. Below is the scope we handle in-house; anything outside it, we'll tell you straight and point you to the right trade.

Unit turns

Patch, paint, clean, re-key, replace what's worn, and hand back a unit that's ready to show. Scoped on walk-through, finished on a date you can put in a lease.

Most requested

Plumbing

Leaks, clogged drains, running toilets, water heaters, fixture swaps, and the under-sink repairs that get a maintenance request closed the same day.

Same-week

Electrical

Dead outlets, switches, lighting, ceiling fans, GFCI replacements, and breaker troubleshooting across common areas and inside units.

Licensed

Painting & drywall

Hole and water-damage repair, texture matching, full interior repaints, and exterior touch-ups so the building reads as cared for.

Interior & exterior

Flooring

Vinyl plank, tile, carpet, and transitions. Replace a single room or re-floor a whole unit between tenants.

Turn-ready

HVAC & appliances

Filter programs, thermostat and unit checks, and repair of washers, dryers, ranges, dishwashers and refrigerators.

Preventive

Doors, locks & hardware

Strike plates, deadbolts, closers, re-keys, cabinet hardware, and the sticking doors residents report twice a month.

Fast fix

How a work order moves through our shop.

Four steps, no mystery. You'll know who's on site, what they found, and what it cost — before the invoice arrives.

"The difference is they finish. We schedule a turn, we get a date, and the unit is ready on that date. I stopped keeping a backup vendor."
