Cast Iron Sewer Replacement in New Haven
Cast iron sewer pipe can corrode from the inside, creating rough surfaces and holes. Scale buildup catches debris and causes clogs. We replace cast iron with PVC or HDPE. This restores flow and ends corrosion. Many homes built before 1975 have cast iron lines.

Sewer Pipe Material Upgrades in New Haven, CT
Many older homes in New Haven, CT still have original sewer lines made of clay, cast iron, or Orangeburg pipe, which are prone to degradation, cracking, and root intrusion over time. When we perform a sewer replacement, we often suggest upgrading to modern, durable materials like PVC (polyvinyl chloride) or ABS (acrylonitrile butadiene styrene). These materials are more flexible, resistant to corrosion and roots, and have a much longer lifespan, providing a major upgrade to your home's plumbing infrastructure.

A collapsed sewer line can cause sewage backups into your home. Call (860) 487-7330 for emergency service. We inspect, locate the break and plan repairs quickly. Temporary measures may restore flow until replacement. Fast response limits damage.
Sewer Cleanout Installation in New Haven, CT
A cleanout provides simple access for future cleaning and inspection. Many older homes lack an exterior cleanout. We install one during sewer replacement. This saves time and money on later maintenance. It also helps in emergencies.
Under-Slab Sewer Replacement in New Haven
Many homes are built on slab foundations with drain lines underneath. When these lines fail, replacement requires tunneling or rerouting. We evaluate options to minimize impact on your home.

Frequently Asked Questions About Sewer Replacement in New Haven
Sewer replacement typically costs $4,500 to $12,000 depending on length, depth and method. Trenchless pipe bursting often runs $6,000 to $15,000, while under-slab work can cost more.
For sewer replacement, we mainly use durable and long-lasting materials like PVC (polyvinyl chloride) and ABS (acrylonitrile butadiene styrene) pipes. These materials are resistant to corrosion, tree root intrusion, and chemical damage, offering a significantly longer lifespan compared to older clay or cast iron pipes commonly found in New Haven homes. We select the best material for your specific property and local conditions.
GLV Plumbing offers solid warranties on both the materials we install and our workmanship for sewer replacement services. The specific warranty period will be clearly outlined in your service agreement, but you can expect several years of coverage. We stand behind the quality and longevity of our installations.
Modern sewer lines are typically replaced with PVC (polyvinyl chloride) piping due to its durability, resistance to corrosion, and smooth interior that minimizes blockages. In some cases, high-quality cast iron might still be used, depending on specific project needs or local codes in New Haven.
The timeline for sewer replacement in New Haven can vary. A simple section replacement might take 1 to 2 days, while a full main line replacement using traditional trenching could take 3 to 5 days. Trenchless methods might be quicker, often completed within 1 to 3 days, depending on site specifics.
Tree roots are a major cause of sewer line damage. Most homes here have full basements, so sump pumps, floor drains, and foundation seepage are frequent plumbing concerns. Shifting soil can crack pipes, and tree roots, attracted to the moisture and nutrients, will work into these cracks, growing inside the pipe and causing severe blockages and even collapses.
We provide a written labor warranty on every sewer replacement. HDPE and PVC pipe also carry long-term manufacturer warranties, and a correctly installed line can last 50 years or more.
Trenchless replacements often take one day. Open-trench jobs can take two to four days.
