Side-by-side decision guides for Gaithersburg

Roofers vs General Contractors Single-system, roof-only? Roofer. Multi-trade or structural? GC. HVAC Contractors vs Plumbers Tankless water heater install crosses both, most plumbers handle it, some HVAC shops do too. Get one quote from each. Electricians vs Handyman Services If it touches the breaker panel or the meter, it's electrician. Insurance and code in most counties require it. Plumbers vs Handyman Services Soldering, gas, sewer, or anything behind drywall = plumber. Drop-in, no-tools-past-a-wrench = handyman. Landscapers vs Tree Services Tree on the ground or coming down: tree service. Garden bed, lawn, or shrubs under 10 feet: landscaper. Painters vs Handyman Services If the customer will judge the finish under direct light, hire the painter. If the paint is incidental to a fix, handyman is fine.
