Call when you're ready to go tankless — or when your tank is on its last legs. We'll take a look, explain options, and give you a flat price before we start.
Challenges we see on this work
What local housing does to this job
Hard water around Arlington and Fairfax is rough on water heaters — it's why a lot of tanks quit at 8 to 12 years, and it's why a tankless needs a regular flush.
Guessing from symptoms alone
Online price averages don't know your house — its age, its pipes, or what code requires here. We do, because we come look.
Association and finish constraints
Condos, co-ops, and remodeled finishes change how we stage work — we document before we cut.
What we do on site
Diagnose first
We check capacity, venting, gas or electric, and hard-water needs, then recommend repair or a right-sized tankless.
Flat-rate after diagnosis
Installs start at $1,900 (range depends on unit and site conditions). You approve the scope before work — no mystery invoices.
Permits when required
We handle the permit if your place needs one. Virginia Master Plumber leadership · 24/7 live answering at (703) 214-2551.
Failure modes to avoid
Skipping the step that prevents callbacks
Especially patching a rusted tank with a new element when replacement is the honest path.
Choosing the cheapest line item without scope match
Two quotes are not comparable if one skips camera work, haul-away, expansion tanks, or association documentation.
