Plumbing Services in Northern Virginia
Reliable plumbing is fundamental to a functional home — and when something goes wrong, it needs to be addressed promptly and properly. Nissi GT Construction LLC provides residential plumbing services for homeowners across Northern Virginia, from fixture installations and upgrades to leak repairs and pipe work integrated into renovation projects.
Fixture Installation & Replacement
Upgrading plumbing fixtures is one of the most impactful and accessible ways to modernize a bathroom or kitchen. Nissi GT Construction LLC installs sinks, faucets, toilets, showers, bathtubs, and utility fixtures with proper supply line connections, sealing, and testing to ensure leak-free, code-compliant results.
Whether you’re refreshing a powder room with a new vanity and faucet or fully outfitting a renovated bathroom with new fixtures throughout, we handle the plumbing from rough-in to final connection.
Leak Detection & Repair
Water leaks cause damage that compounds quickly — from stained drywall and swollen subfloors to mold growth and structural deterioration. Nissi GT Construction LLC addresses leaks at the source, whether that’s a dripping faucet, a leaking shut-off valve, a failed wax ring beneath a toilet, or a supply line that’s begun to fail.
We locate the source of the problem accurately before opening walls or floors unnecessarily, minimizing disruption and keeping repair costs reasonable.
Pipe Upgrades & Replacement
Many Northern Virginia homes built in the mid-20th century contain aging galvanized steel or polybutylene piping that has reached the end of its reliable service life. Nissi GT Construction LLC replaces outdated piping with modern copper or PEX systems that restore proper water pressure, eliminate rust contamination, and dramatically reduce the risk of future leaks.
Plumbing for Renovations
Renovation projects frequently involve plumbing relocation, new fixture rough-in, or drain reconfiguration. Nissi GT Construction LLC coordinates plumbing work as an integrated part of kitchen and bathroom renovations, ensuring supply and drain lines are properly placed and tested before walls are closed.
