What Every Visit Looks Like

The work is only half of what we do. The rest is how we show up. After more than a decade of serving the DMV area, this is what you can count on from every Tim Whistler Plumbing visit.

Let's talk

Clear communication

A text before we arrive. A plain-English explanation of what we're seeing once we look at it. A written quote before any work starts. If something unexpected comes up during the job, we stop and ask before we touch it.

Always on time

We make an effort to be on time, every time. You'll get a real arrival window, not an all-day guess. We text when your technician is on the way and call ahead if anything shifts. Your time matters as much as ours.

Honesty and dedication

If a repair makes more sense than a replacement, we'll tell you. Honest service without pushy upselling. And once we start a job, we don't leave until it's done right, even if it takes longer than we estimated.

Quality parts

Every truck is stocked with name-brand fittings, valves, and fixtures. The bottom-shelf parts at the big-box stores costs us less today but costs you thousands more in three years. We only put high quality parts in your home.

FAQs

Common Questions You May Have

These are the most common questions people ask our professional plumbers and electricians.

Let's talk

Do we install tank and tankless water heaters?

Yes. We install, replace, and service traditional tank water heaters and ENERGY STAR rated tankless gas systems for homes and businesses across Washington DC, Maryland, and Northern Virginia. We handle the gas, water, and venting work in-house since our team is licensed across plumbing, gas, and HVAC. Tankless conversions often qualify for utility rebates, and we'll walk you through which option makes sense for your home.

Do you install EV chargers and handle electrical panel upgrades?

Yes. Our licensed electricians install Level 2 EV chargers and handle full electrical panel upgrades (100A, 200A, and 400A) across the DMV. Older homes often need a panel upgrade to support modern loads like an EV charger, heat pump, or solar system. Every project is permitted, inspected, and brought to current code. Call 1-866-477-6190 for a panel evaluation.

Do you offer free estimates?

Yes. We provide free estimates for most installation and replacement projects, including water heaters, boilers, AC units, panel upgrades, gas line work, and full system installations. For diagnostic work on existing equipment (like an AC that isn't cooling), there may be a small service call fee that's credited toward the repair if you move forward. Call 1-866-477-6190 to schedule.

Do you offer 24/7 emergency plumbing, gas, HVAC, and electrical service?

Yes. Tim Whistler Plumbing offers true 24/7 emergency response for plumbing, gas, HVAC, and electrical issues across the DMV. Whether it's a burst pipe at 2 a.m., a suspected gas leak, a furnace that died on the coldest night of the year, or a panel that's tripping breakers, we have a licensed technician available. Call 1-866-477-6190.

Do you serve Bethesda, Arlington, Silver Spring, and the rest of the DC metro?

We're regularly on jobs in Bethesda, Chevy Chase, Tyson's Corner, Falls Church, McLean, Kensington, Takoma Park, Old Town Alexandria, Northwest DC, and surrounding neighborhoods.

Testimonials

Don’t just take our word for it

I called Tim Whistler for estimates on three distinct jobs: two HVAC and one plumbing. Chris H came out, was professional, explained everything (including why I probably should not do one of the more costly HVAC jobs!!!), and was patient. Surprisingly, they did not charge for the estimates. A competitor wanted over $300 just to do the estimates.

Jesse G.

Washington, DC

We needed some gas lines redirected, and Tim Whistler was available quickly and offered a free quote. The employees were friendly and professional and pointed out some issues and made relevant suggestions. The work was agreed upon after we received the quote, and the service team were prompt and did an excellent job.

These folks seem like honest businesspeople who don't try to upsell you.
