Tankless Water Heater Installation
Tankless water heater installation across the DMV. Serving DC, Maryland, and Virginia from Suitland, MD.
A tankless water heater makes hot water the moment you ask for it and never runs out. No tank to fill, no tank to run dry, and no tank taking up a corner of your basement or closet.
Going tankless is a different install than a tank swap. The venting, the gas sizing, and the water connections all change, and getting them wrong is how a great unit turns into a headache. We have installed them across the DC metro for years, and we do the whole conversion to code.
Is tankless right for your home
Tankless is not automatically the right answer for every house. It shines for households that run out of hot water, families with staggered schedules, and homes where floor space is tight. We look at your gas service, your demand, and your budget and give you a straight answer.
- Whole-home tankless units sized to your actual demand
- Gas line upsizing when the new unit needs more supply
- Proper venting runs, done to code and permitted where required
- Tank-to-tankless conversions with the old tank hauled away
- Recirculation options so the far bathroom gets hot water fast
What to expect on the day
After the repair is finished, we test it under normal use before anyone packs up: water on, drains running, pressure checked where it applies. Then Brandon walks you through what he found, what he fixed, and anything worth keeping an eye on. All of that comes after the part you already know about, the diagnosis and the price you approved before a single tool came out. We leave the work area clean, and you end the visit knowing exactly what you paid for.
Big replacement or small repair, Brandon prices it up front and leaves the place clean when he is done. See examples in the gallery of recent work, then tell us what you need or pick up the phone at any hour.
A conversion done right the first time
The most common tankless complaint is a unit that was slapped onto an old tank setup without touching the gas or venting. It short-cycles, underperforms, and fails early. We size the gas, run the venting correctly, and commission the unit so it performs the way the manufacturer intended.
You get the honest math up front too. If a standard tank actually fits your home and budget better, we will say so.
- Gas and venting sized correctly, not reused blindly
- Commissioned and tested before we leave
- Honest tank-vs-tankless advice
Why the DMV calls Jackson Plumbing
Too many companies in the Washington metro treat an arrival time as a suggestion. When we give you a window, we mean it, and same-day response is normal for us. Our phone is answered 24 hours a day. Once we arrive, you get a price before we start, and the bill at the end matches it. One customer put it simply: he shows up when he says he is coming.
Brandon Jackson has spent nearly three decades in this trade, and he built the business around a simple idea: treat people the way you would want to be treated in your own home. That means explaining what is wrong in plain language, giving you honest options instead of the most expensive one, and leaving the space cleaner than we found it. It is why so much of our work comes from repeat customers and neighbor-to-neighbor referrals across DC, Maryland, and Virginia.
When you hire us, the licensed Master Plumber on the paperwork is the plumber who answers for your job. That is Brandon, license PLM40000116, also credentialed in Maryland (109495), Virginia (2710083375), and with WSSC (P-83640), ASSE certified, and A-rated by the BBB. The same qualified plumber handles the diagnosis, the permits, and the final connection.
Plenty of plumbing outfits come and go, and we plan to keep answering the same phone number for a long time. Brandon means to keep his name good in the DMV, so we fix things to last, and if something we did ever acts up, we come back and handle it. A customer who trusts us is worth far more to us than one quick ticket.
Honest pricing, no hidden fees
Before anyone can give you a fair number, somebody has to figure out what is actually wrong. So Brandon finds the cause first, then prices the fix, and you hear that price on site before a single fitting comes off. You decide whether we go ahead. Once you say yes, nothing gets tacked on, and nothing shows up at the bottom of the invoice that you did not hear about first. The bill at the end matches what you agreed to. One customer summed it up in a review: fair pricing, no hidden fees. That is the whole policy, and it has not changed since Brandon started this business. Call (202) 840-1998 any hour of the day or night, or send us the details and Brandon will call you back.

How is a tankless install different from a tank swap?
A tankless unit needs different venting, often a larger gas line, and new mounting and connections. It is a conversion, not a swap, which is why it takes longer and why the installer’s skill matters more.
Will a tankless heater really never run out of hot water?
It heats water as it flows, so it does not run out the way a tank does. The unit does have a flow limit, which is why sizing to your household’s real demand matters. We size it right so showers and laundry can run together.
Does my gas line need to be upgraded?
Sometimes. Tankless units draw more gas while running than most tanks. We check your existing service and upsize the line if the new unit needs it, all to code.
How long does a tankless installation take?
A straight replacement of an existing tankless is quick. A first-time conversion from a tank usually takes the better part of a day because of the venting and gas work. We give you a real window before we start.
Is tankless worth the higher up-front cost?
For many DMV homes, yes: lower operating cost, longer service life, and endless hot water. For lighter use, a tank can still be the smarter buy. We will give you the honest math for your house.
