Professional drain repair for all pipe materials including PVC, cast iron, copper, and clay. We fix the problem at its source to stop leaks, prevent backups, and restore proper drainage.

Emergency Drain Service

Emergency drain problems need immediate attention. We dispatch experienced technicians with commercial equipment any time — day, night, weekends, or holidays — to resolve your drain emergency fast.

Sewer Line Cleaning

Complete sewer line cleaning that goes beyond simple snaking. We scour pipe walls with hydro jetting equipment to remove years of buildup and restore your sewer line to near-original capacity.

Sewer Backup

Sewer backup emergencies require immediate action. We dispatch crews fast to stop the overflow, clear the line, and restore sanitary conditions — then find and fix the root cause.

Sewer Camera Inspection

Advanced video camera inspection of your sewer and drain lines. Real-time footage identifies problems, pinpoints locations, and helps us recommend the most cost-effective solution.

Professional drain cleaning for kitchens, bathrooms, floor drains, and main lines. We clear clogs caused by grease, hair, soap, and debris using cable machines and hydro jetting.

Sewer Line Repair

Professional sewer line repair for cracks, leaks, offsets, and root damage. We diagnose the problem with camera inspection and use the most effective repair method — traditional or trenchless — to restore your sewer line.

Drain Snake Service

Professional drain snaking using commercial-grade cable machines to break through tough clogs in sinks, tubs, showers, and main drain lines. Fast, effective, and safe for your pipes.

Commercial Drain Cleaning

Industrial-strength commercial drain cleaning for restaurants, retail spaces, offices, and multi-unit buildings. We handle grease lines, floor drains, main sewers, and everything in between.

Grease Trap Cleaning

Complete grease trap maintenance including pumping, scraping, and cleaning. We document service for health department records and recommend optimal cleaning intervals based on your kitchen volume.

Sewer Line Installation

Complete new sewer line installation using modern pipe materials rated for decades of service. We coordinate with local utilities, pull permits, and ensure code-compliant connections.

Sewer Cleanout

We install and service sewer cleanouts to provide direct access to your main drain line. Essential for properties without existing cleanout access, older homes, and properties with recurring issues.

Sewer Line Relining

Sewer line relining seals cracks, closes root entry points, and restores flow capacity without excavation. We pull a resin-coated liner through your existing pipe and cure it in place for a permanent fix.

Clogged Drain Repair

Fast clogged drain repair for stubborn blockages in kitchens, bathrooms, laundry rooms, and main lines. We break through grease, hair, soap scum, and foreign object clogs quickly.

Hydro Jetting

Professional hydro jetting that removes everything from your pipe walls — tree roots, hardened grease, calcium buildup, and years of accumulated debris. Restores full pipe capacity in a single visit.

Trenchless Sewer Repair

Minimally invasive trenchless technology repairs cracked, root-damaged, and deteriorating sewer lines from the inside. No trenching, no landscaping destruction, no lengthy restoration projects.

Storm Drain Cleaning

Storm drain cleaning and maintenance to prevent flooding, standing water, and property damage during heavy rain. We clear debris, silt, and buildup from storm drain systems of all sizes.

Sewer Line Replacement

Full sewer lateral replacement using traditional excavation or trenchless pipe bursting. We remove old clay, cast iron, or Orangeburg pipe and install modern materials designed to last 50+ years.

Frequently Asked Questions

Common questions about sewer and drain services in Merrimack, NH.

How do you diagnose sewer problems in Merrimack without digging?

We use a specialized waterproof camera that is inserted into your sewer line through a cleanout. The camera transmits real-time video that shows us the exact location and nature of any blockage, crack, offset joint, or root intrusion. This lets us recommend the most cost-effective repair for your Merrimack property without any excavation.

What is trenchless sewer repair and is it available in Merrimack?

Trenchless sewer repair uses pipe lining or pipe bursting technology to fix damaged sewer lines without digging up your yard, driveway, or landscaping. It is faster, less disruptive, and often costs less than traditional excavation. Our Merrimack crews perform trenchless repairs when site conditions allow — saving you time, money, and landscaping restoration costs.

Does homeowners insurance cover sewer line repair in Merrimack, NH?

Most standard homeowners insurance policies in Merrimack do not cover sewer line repair due to normal wear and aging. However, sudden damage from events like tree root intrusion or ground shifting may be partially covered. Some carriers offer sewer line endorsements. We help Merrimack homeowners understand their coverage and provide documentation for claims that do apply.

Do you handle both residential and commercial drain cleaning in Merrimack?

Yes. Our Merrimack, NH teams are equipped for drain cleaning at any scale — from residential kitchen and bathroom drains to commercial restaurant grease lines, multi-unit buildings, and industrial facilities. We carry equipment rated for pipes from 1.5 inches to 12 inches in diameter.

What are signs I need sewer line repair in Merrimack?

Common warning signs for Merrimack homeowners include multiple slow drains, gurgling toilets, sewage odors in the yard or basement, soggy patches in the lawn, and recurring drain backups. If you notice any of these, call us for a sewer camera inspection to diagnose the problem before it becomes a costly emergency.

How long does a drain cleaning take in Merrimack?

Most residential drain cleaning jobs in Merrimack, NH take 30 minutes to 2 hours depending on the severity of the clog and the number of drains affected. Main sewer line cleaning may take longer. Our crews arrive with professional-grade snaking equipment and hydro jetting capability to handle any blockage quickly.

What Our Customers Say

Honest feedback from property owners who trusted Scranton Sewer Authority with their sewer and drain projects.

★★★★★

"This company installed a cleanout for us after we had repeated backup issues. Now maintenance is easy and we have not had a backup since. Should have done this years ago."

— Michael Donovan
★★★★★

"Our laundry drain kept backing up no matter how many times we used store-bought cleaners. One professional cleaning visit and the problem has not come back in six months. Wish I had called sooner."

— Sandra Brooks
★★★★★

"Very fair company. They quoted a drain snaking, found out it needed hydro jetting instead, and honored the original quote even though jetting costs more. That kind of integrity earns repeat business."

— Sharon DiNardo
