The six home services homeowners hire for most — what each trade actually does, when you need a permit, and what a professional job looks like.
Every trade has its own credentials, pricing habits, and red flags. Here is what to expect before you pick up the phone.
Remodels are usually run by a licensed general contractor who coordinates demolition, framing, plumbing, electrical, and finish work — often with subcontractors for each trade. Expect a detailed written scope, a payment schedule tied to milestones, and a timeline measured in weeks, not days. Permits are almost always required when walls, plumbing lines, or wiring move.
Roofers handle repair, partial replacement, and full tear-offs. A professional bid names the shingle or membrane product, includes underlayment and flashing details, and covers debris haul-away. Ask about both the manufacturer warranty on materials and the contractor's own workmanship warranty — they are two different things, and you want both in writing.
Heating and cooling contractors install and service furnaces, heat pumps, air conditioners, and ductwork. The mark of a careful pro is a load calculation — sizing the equipment to your home instead of simply matching the old unit. Oversized or undersized systems cost more to run and wear out faster, so be wary of quotes given without a site visit.
Licensed electricians handle panel upgrades, rewiring, new circuits, and EV charger installation. Electrical work almost always requires a permit and an inspection, and that protects you — an unpermitted panel job can complicate insurance claims and home sales later. Never hire unlicensed help for anything behind a wall or inside a panel.
Plumbers cover everything from water heater swaps and fixture installs to repiping and sewer line repair. Small jobs are often flat-rate; larger jobs deserve a written estimate that separates labor from materials. Because water damage is expensive and slow to reveal itself, verified licensing and active liability insurance matter more here than almost anywhere.
Window and door installers replace single units or whole-house sets. A good quote specifies the exact product line, glass package, and installation method — full-frame versus insert — because those choices drive both price and performance. Energy-efficient replacements can also qualify for local utility incentives, so ask what applies in your area.
Whichever trade you are hiring, the fundamentals do not change.
Current state or local license plus active liability and workers' comp coverage — verified, not just claimed.
Itemized scope, materials, and labor in writing. Verbal ballparks are not bids.
The contractor — not you — should pull permits in their own name when the work requires one.
