Paint & Drywall Repair

Drywall patching (self-adhesive mesh tape for small, paper tape for joints, setting-type 'hot mud' for deep fills, drying-type all-purpose for finish), corner bead repair, texture matching (knockdown, orange peel, smooth wall), primer selection (PVA on new drywall, stain-blocking oil/shellac for water stains and smoke, bonding primer over glossy), interior paint sheens (flat/matte for ceilings, eggshell and satin for living areas, semi-gloss for trim and baths), proper surface prep (TSP or degreaser, sanding, caulking gaps), cutting in with a brush and rolling with 3/8-in nap for standard walls, color matching for turn-unit consistency.

Appliance Repair

Refrigerators (compressor, defrost timer/heater, evaporator fan motor, condenser coil cleaning, door gasket replacement, icemaker water line), dishwashers (water inlet valve, drain pump, float switch, spray arm clearing, door latch), electric/gas ranges and ovens (bake and broil elements, surface burners, gas igniters and safety valves, control boards), microwaves (safety first — never bypass door interlock; high-voltage capacitor must be discharged; most apartment maintenance limited to replace rather than repair), clothes washers (drive belt, drain pump, lid switch, agitator dogs), dryers (lint trap and dryer vent cleaning annually — major fire hazard, thermal fuse, high-limit thermostat, heating element, drive belt, idler pulley).

Apartment Turn Process

Move-out inspection with photos and damage documentation, scope of work and make-ready checklist, correct sequence — trash-out, deep clean, paint, floor (carpet replace or clean/LVP), appliance check, punch list walk; security deposit accounting principles and state-law itemization; vendor coordination (carpet, paint, cleaning, pest); quality-control inspection before listing available; typical 3-5 day target turn time in stabilized properties; communication with leasing about ready date.

Preventive Maintenance

Seasonal PM schedules (HVAC spring and fall, coil cleaning, condensate pan treatment with tablets, filter replacement quarterly for 1-in pleated MERV 8-11), water heater flushing, annual dryer vent cleaning, smoke/CO alarm testing and battery replacement, monthly GFCI and AFCI test, exterior caulking and paint touch-up, gutter and downspout cleaning, pressure washing building surfaces, irrigation winterization (blow-out), pool/spa chemistry (chlorine/pH, where applicable), unit and common-area walks.

OSHA & General Safety

OSHA 29 CFR 1910 general industry requirements, Hazard Communication (GHS — SDS always accessible, GHS labels and pictograms), PPE (safety glasses, cut-resistant and chemical gloves, N95/half-face for dust, hearing for power tools), lockout/tagout (LOTO) procedures before any electrical or mechanical service, ladder safety (3-point contact; 4:1 ratio for extension ladders; never top two rungs), fall protection required at 6 ft in general industry, electrical safety — always de-energize and verify zero energy, chemical storage and compatibility (oxidizers away from flammables), bloodborne pathogens basics for needle-stick response, heat illness prevention.

Flooring

Carpet installation (cut pile, loop, Berber), stretching with a power stretcher and knee kicker, seam tape and hot iron, tack strip, carpet pad replacement, spot stain treatment; sheet vinyl (seam sealer), vinyl plank (LVP/LVT) floating click-lock installs with underlayment and expansion gap at walls; ceramic and porcelain tile crack repair, regrouting, and caulking wet joints instead of grout; laminate plank replacement (disassembly to damaged plank); transition strips (T-molding between same-height, reducer for height change, threshold at exterior doors).

Pest Control & IPM

Integrated Pest Management (IPM) principles — identification first, monitoring, prevention (exclusion, sanitation), mechanical/biological controls before chemical, and targeted pesticide application; common multifamily pests (German cockroach, ants, bed bugs, rodents, termites); bait stations (gel for roaches, perimeter bait for ants), exclusion (caulk gaps, door sweeps, pipe penetrations with steel wool); most states require a licensed Pest Control Operator (PCO) for pesticide application inside units — in-house maintenance boundaries; bed bug protocol coordination (inspection, heat or chemical treatment by PCO, resident prep).
