Leak Detection and Slab Screening in Wilmington
A spinning water meter with all fixtures off is a clear sign of a hidden leak. We test the meter, check pressure loss and inspect for warm spots, damp baseboards and mildew. On slab homes we can follow up with acoustic and thermal equipment to pinpoint leaks. Catching a slab leak early reduces damage to floors and foundations.

Pre-Purchase Plumbing Inspection in Wilmington
Before buying a home in Wilmington, a pre-purchase plumbing inspection by GNV Plumbing can save you from inheriting costly problems. Our detailed report will highlight any existing or potential plumbing issues, from faulty fixtures to aging main lines. This helps you to make an informed decision, negotiate repairs, or budget for future plumbing needs, avoiding unwelcome surprises after closing. It's an essential step for any homebuyer in Delaware.
Leak Detection and Assessment in Wilmington, DE
Our inspections include precise leak detection, using acoustic listening devices and thermal cameras to pinpoint hidden leaks behind walls, under floors, or in slab foundations. Early detection of leaks is vital to prevent extensive water damage and costly foundation repairs. Sandy soil drains quickly but can shift and settle, which may stress buried sewer lines and water service pipes over time.
Water Pressure and Supply Pipe Review in Wilmington, DE
We measure static water pressure and check the pressure reducing valve if one is installed. High pressure above 80 psi shortens the life of fixtures and appliance hoses. We also identify supply pipe material, from copper and CPVC to polybutylene, Kitec and galvanized. Knowing what you have helps you plan repairs or a full repipe.
Sewer Line Camera Inspection in Wilmington, DE
Using modern fiber-optic cameras, we perform detailed sewer line inspections to diagnose problems deep within your drainage system. This allows us to precisely locate blockages, tree root intrusions, cracks, or collapsed pipes without invasive digging. This technology is crucial for homes in Wilmington with older cast iron or clay pipes that are prone to deterioration and root damage from the local soil conditions. It saves you time and money by pinpointing the exact problem.
Sewer Line Camera Inspections in Wilmington, DE
Using modern waterproof cameras, we conduct sewer line inspections to identify blockages, cracks, or tree root intrusion without invasive digging. This diagnostic tool is essential for detecting problems in underground lines that can lead to significant backups and damage, especially where shifting soil moves buried pipe. Sandy soil drains quickly but can shift and settle, which may misalign buried sewer lines and water service pipes over time.
Water Quality & Pipe Material Inspection in Wilmington, DE
We inspect your plumbing for problems related to local water quality and common pipe materials. Hard water can lead to mineral buildup, reducing pipe diameter and appliance efficiency. We assess the condition of various pipe types, including copper, PEX, and older galvanized or polybutylene pipes, which are common in some Wilmington homes and known for potential failure. Our inspection helps identify pipes at risk and recommend appropriate solutions.

Preventative Maintenance Checks in Wilmington, DE
Preventative maintenance checks are designed to keep your plumbing system operating smoothly year-round. These inspections are ideal for careful homeowners who want to avoid emergency repairs. We focus on identifying wear and tear on pipes, checking for early signs of leaks, assessing water pressure, and making sure all drains are clear. Regular checks can greatly extend the life of your plumbing system and prevent unexpected breakdowns in your Wilmington residence.
