Whole-Home Repiping & Sewer Repair

Why Repiping Makes Sense for D.C. and Northern Virginia Homes

If you own an older home in Washington D.C., Arlington, Alexandria, or Fairfax County, you are likely dealing with aging plumbing infrastructure. Many homes built before the 1980s still rely on galvanized steel pipes that corrode from the inside out, leading to low water pressure, rusty water, and hidden leaks. In the District, we also see a major push for lead pipe replacement. Through the "Lead Free DC" Under DC Water's Lead Free DC block-by-block program, District funding now covers private-side replacement as well, free for residents regardless of income, so check whether your block is scheduled before paying for it yourself. Leaving old, compromised pipes in your walls is a ticking time bomb that can cause catastrophic water damage and disrupt your daily life.

At i4improvements, we approach repiping with a contractor's eye for the whole house, not just the plumbing. When we open up walls to run new PEX or copper lines, we know exactly how to patch, repair, and restore your home to its original condition. If your property is located in one of the District's historic neighborhoods, we understand how to navigate the Historic Preservation Review Board (HPRB) guidelines to ensure any exterior venting or structural modifications remain fully compliant. For landlords preparing a property for the rental market, a full repipe is often a necessary step to secure your Basic Business License (BBL) and avoid burst-pipe calls from tenants down the road.

A whole-house repipe might sound like a massive, month-long disruption, but a typical job is much more streamlined. For a standard single-family home in Fairfax County or Arlington, our crews usually complete the repiping process in three to five days. We sequence the work so you maintain access to running water for as much of the project as possible. Pricing depends heavily on the size of your home, the number of bathrooms, and the ease of access to your existing plumbing, but you are paying for a permanent solution that adds immediate value to your property. If your water heater is near the end of its life, the repipe is also a sensible time to replace it.

Old galvanized pipe doesn't fail on a schedule. If your water pressure has been creeping down, or a home inspection flagged original plumbing, the cost of a full repipe is almost always less than the damage a burst line causes.
