Tank vs. Tankless: Which Is Right for Your Home
Most people don't know which type they need when they call me. That's fine. Here's how I think about it. A tank water heater is lower upfront cost, easier to install, and works well for most DC and Bethesda homes. If you've got a standard gas or electric setup and you're not running out of hot water regularly, a tank replacement is usually the right call. They typically last 10 to 12 years. A tankless water heater costs more upfront but heats water on demand, so you're not paying to keep a tank warm around the clock. Good fit for smaller homes, households that want to cut energy costs long-term, or anyone who's tired of running out of hot water. The installation is more involved, especially if you're switching fuel types or upgrading your gas line. I'll tell you which one makes sense for your home and your budget. No upsell. If a tank replacement does the job, that's what I'll recommend.
Repair vs. Replace
Replacing an Old Water Heater Before It Fails
A lot of my water heater installations start as repair calls. Someone has no hot water, I come out, and what I find is a unit that's 12 or 15 years old with a corroded anode rod, sediment buildup, or a tank that's already showing rust. At that point, repair is just delaying the inevitable.
I'm not going to push you toward a replacement if a repair genuinely makes sense. But I'll be honest with you about what I find. If the unit is old and the repair cost is approaching half the cost of a new installation, I'll tell you that directly. You can read more about how I approach that decision on my water heater repair page.
The smarter move is often replacing before you're dealing with a flooded utility room. A failing tank doesn't always give you warning. If yours is over ten years old and you've had any issues, it's worth a conversation.
DC Licensed Installation
Licensed Installation: Why It Matters
Water heater installation in DC requires a permit. That's not a technicality you can skip. An unpermitted installation can create problems when you sell your home, and more immediately, it means the work wasn't inspected. I handle the permit process as part of every installation.
Being DC licensed means I'm accountable to the District's standards for this work. Bonded and insured means you're covered if something goes wrong. I've seen homeowners get burned by unlicensed work that looked fine until it didn't. Proper installation means the right connections, the right pressure relief valve, the correct venting for gas units, and everything tied in to code.
If you're switching from a tank to tankless, or changing fuel types, there's more involved: gas line sizing, electrical capacity for electric units, condensate drainage for certain tankless models. I'll walk you through what your home needs before any work starts.

Common Questions
Frequently Asked Questions
How much does water heater installation cost in DC? It depends on the type of unit, your home's existing setup, and whether any additional work is needed like a gas line upgrade or expansion tank. A standard tank replacement runs less than a tankless installation, which involves more labor and sometimes additional materials. I'll give you a clear number before any work starts. No surprise charges after the fact.
Should I get a tankless or tank water heater? For most DC and Bethesda homes with a standard gas setup, a tank replacement is straightforward and cost-effective. Tankless makes more sense if you want long-term energy savings, you're running out of hot water regularly, or you have the space and budget for the upfront cost. I'll tell you which one fits your situation after I see what you're working with.
How long does water heater installation take? Most installations take three to five hours. If there's additional work involved, like upgrading a gas line or installing an expansion tank, it may run longer. Either way, you'll have hot water the same day.
