Few areas have older plumbing than Old Town and Del Ray, where original supply lines and shutoff valves have been in place for decades and often no longer fully close. A hidden leak in a historic home can damage irreplaceable plaster and woodwork fast, so we use careful, targeted leak detection to find the source with minimal disruption, then repair or replace the failing line, valve, or fixture — respecting both the plumbing and the house.

Repairs & Leaks in Alexandria — FAQs

Do you find leaks in historic Old Town Alexandria homes?

Yes. We use targeted leak detection to locate hidden leaks with minimal disruption to plaster, woodwork, and finishes, which matters in older Old Town and Del Ray homes. Then we repair the source carefully.

My old Alexandria shutoff valve won’t close and it’s leaking — can you help?

Yes. Aging valves in historic homes often seize or weep. We can reach the main shutoff to stop the water, then replace the failed valve with a reliable quarter-turn one.

My Alexandria water bill jumped — where’s the leak?

Often a running toilet, a dripping fixture, or a hidden supply-line leak in an aging line. We check the visible spots first, then use leak detection to find anything concealed in a wall or under the floor.
