Tim Whistler Plumbing has served Bethesda homes and businesses for over a decade. From the brick Tudors and Cape Cods around Edgemoor and Maplewood to the larger custom builds along Burning Tree and Glen Echo Heights, we work across the full range of Bethesda housing, residential and commercial. Every job is performed by a licensed plumber, gas fitter, HVAC technician, or electrician, with permits pulled and inspections coordinated when the work calls for it.
We handle plumbing repairs and installations (leaks, water heaters, tankless conversions, drain cleaning, sewer line work, full repipes), gas fitting (gas line installation, appliance hookups, outdoor grill and fire pit lines, gas leak diagnosis and repair), heating and cooling (boiler service, furnace and heat pump installation, central AC and ductless mini-split work, annual tune-ups), and licensed electrical work (panel upgrades, EV charger installation, dedicated circuits, whole-home surge protection, generator installation). For commercial properties, our team handles permitted work for offices, restaurants, retail, multi-tenant, and medical buildings across the Bethesda corridor.
Bethesda has a wide range of housing stock and a wide range of plumbing situations. The 1940s and 1950s ranchers around Wyngate and the older Tudors in Edgemoor often have original galvanized supply lines that need updating, cast iron drain stacks at the end of their service life, and aging gas lines that fail safety pressure tests. We see these issues every week and know how to plan a phased upgrade that minimizes disruption. Newer construction in the Bethesda corridor brings different problems, including high-efficiency boiler maintenance, tankless water heater service, and panel capacity for modern loads like EV chargers and induction ranges.
Bethesda's mix of pre-1970 housing and modern luxury construction means most homes here have both old-school plumbing concerns and modern electrical demands. We are licensed across all four trades, which means a kitchen remodel or basement finish in your Bethesda home can run under one schedule instead of coordinating four contractors.
When something fails at 2 a.m., the response time is what matters. We dispatch licensed technicians to Bethesda emergency calls around the clock, every day of the year. Common Bethesda emergencies we respond to include burst supply lines (especially during winter freeze-thaw cycles), sewer line backups, water heater failures, gas leaks, no-heat calls in winter, and no-cool calls in summer. Call 1-866-477-6190 day or night and we will give you an honest ETA.
We work across all Bethesda neighborhoods including Edgemoor, Maplewood, Battery Park, Burning Tree, Glen Echo Heights, Wyngate, Bradley Park, Westmoreland Hills, East Bethesda, Bradley Hills, Fernwood, and the wider 20814 and 20817 ZIP codes. If you are in a Bethesda neighborhood not listed and want to confirm we cover your area, call 1-866-477-6190.
Yes. WSSC Water serves Bethesda, and any plumbing work that requires a permit (water main service replacement, certain gas line work, backflow installations) is pulled with WSSC by our team. We meet the inspector on site and handle the certification. Our WSSC plumber license is 6119360.
It depends on the condition of the lines, your water pressure, and whether you have signs of corrosion (rust-colored water, low flow at multiple fixtures, recurring pinhole leaks). Many Bethesda homes built before 1970 have galvanized supply lines that are at or past their service life. We can evaluate during a plumbing inspection and walk you through whether a partial or full repipe makes sense for your home.
Often we can, but the panel may need to be upgraded first to handle the new circuit. A typical 100 amp to 200 amp panel upgrade in Bethesda runs roughly $2,500 to $5,000 depending on the existing service entrance and meter base. We handle the panel upgrade and the EV charger install together under one schedule, with Montgomery County permits pulled and inspections coordinated.
