Emergency Basement Flooding Response in New Haven
A burst pipe or a failed sump during a storm can put inches of water on the floor in minutes. Call us and shut off the main water valve if you can do so safely. We stop the leak, pump out standing water from the plumbing failure and make the system safe. We can also point you to drying and restoration crews when the damage calls for it.

Drain and Sewer Pipe Leak Repair in New Haven, CT
Cast iron drain stacks in older homes crack and scale with age, and plastic joints can separate if a line was poorly supported. These leaks usually show up only when an upstairs fixture runs. We run water through each drain while watching the basement, then verify the crack with a camera. Repairs range from a single section swap to replacing an entire stack with PVC or ABS.
Floor Drain and Backwater Valve Repair in New Haven
A basement floor drain that backs up during heavy use or a storm usually points to a blockage or a failed trap. We clear the drain, check the line to the main sewer and replace cracked traps and covers. Installing a backwater valve stops sewage from pushing back into the basement if the main line surcharges. We set the valve where it can be serviced easily.
Exterior Waterproofing Solutions in New Haven, CT
For complete basement leak prevention, exterior waterproofing involves excavating around your foundation and applying waterproof membranes or coatings. This creates a robust barrier against moisture intrusion from the outside. While more involved, this method offers superior long-term protection against water damage, especially for older homes in New Haven.
Waterproofing for Older Connecticut Homes in New Haven, CT
Many older homes in New Haven and across Connecticut were not built with modern waterproofing techniques, making them more prone to basement leaks. Some older homes here may have lead service lines or lead solder on copper pipes, which is worth checking if you have young children. GLV Plumbing focuses on retrofitting older foundations with current solutions, addressing issues like failing mortar, porous concrete, and inadequate drainage. We preserve the integrity of historic structures while providing modern protection.
Clogged Drain Tile Repair in New Haven
Interior or exterior drain tile systems can become clogged with sediment or tree roots over time, rendering them ineffective. We specialize in diagnosing and clearing blockages in these critical drainage systems, restoring their ability to divert water away from your basement walls and foundation in New Haven.
Interior Drainage Systems in New Haven
When exterior excavation isn't practical, interior drainage systems provide an effective solution for managing basement leaks. We install perimeter drains along the basement walls, collecting water before it can surface and directing it to a sump pump for removal. This system is less invasive and can be a cost-effective way to dry out a wet basement.

Water Damage Assessment in New Haven, CT
Before any repair, our team performs a thorough water damage assessment to identify the source and extent of your basement leak. This includes inspecting for mold growth, structural concerns, and damaged finishes. Our comprehensive approach ensures that all related issues are addressed for a full restoration of your New Haven basement.
