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.

Drain Repair

Drain pipe repair that addresses the root cause, not just the symptom. We camera-inspect, identify the failure point, and repair or replace the damaged section for lasting results.

Sewer Line Cleaning

Thorough sewer line cleaning to remove grease, sludge, roots, and mineral deposits. We use hydro jetting and mechanical cleaning to restore full flow to your main sewer line.

Sewer Line Repair

Expert sewer pipe repair using proven techniques for every pipe material. We fix cracked, corroded, and root-damaged sewer lines with minimal property disruption and lasting results.

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.

Clogged Drain Repair

Professional clog removal using drain snakes, augers, and hydro jetting. We clear tough blockages that store-bought cleaners and home remedies cannot touch, then verify clear flow with camera inspection.

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.

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

Professional CIPP relining to rehabilitate cracked, root-damaged, and leaking sewer lines from the inside. The epoxy-saturated liner cures in place and restores structural integrity without digging.

Around-the-clock emergency drain service for overflowing drains, sewage backups, and flooding. We respond fast with professional equipment to stop the emergency and protect your property.

Sewer Backup

Emergency sewer backup response to stop sewage overflow, clear the blockage, and clean up affected areas. We respond 24/7 to protect your property and your health.

Grease Trap Cleaning

Professional grease trap pumping, cleaning, and maintenance to keep commercial kitchens compliant with health codes and drains flowing freely. We handle all sizes from under-sink units to large in-ground traps.

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.

Drain Cleaning

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 Installation

New sewer line installation for additions, new construction, and properties connecting to municipal sewer for the first time. Proper grade, materials, and connections for long-term reliability.

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.

Drain Snake Service

Commercial drain snaking for residential and commercial properties. Our motorized cable machines clear roots, grease, and debris from drain lines up to 100 feet or more from the access point.

Trenchless Sewer Repair

Trenchless sewer repair fixes damaged pipes without excavation. We use CIPP lining or pipe bursting to rehabilitate your sewer line while preserving your yard, driveway, and landscaping.

Frequently Asked Questions

Have questions about sewer or drain service in Portsmouth? We have answers.

What causes recurring drain clogs in Portsmouth homes?

Recurring clogs in Portsmouth homes are usually caused by grease buildup inside drain lines, tree root intrusion into sewer pipes, pipe bellies or offsets that trap debris, or undersized plumbing. A sewer camera inspection identifies the root cause so we can fix the real problem, not just clear the symptom temporarily.

What are signs I need sewer line repair in Portsmouth?

Common warning signs for Portsmouth 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.

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

Yes. Our Portsmouth, 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.

Can tree roots damage my sewer line in Portsmouth?

Absolutely. Tree root intrusion is one of the most common causes of sewer line damage in Portsmouth, NH. Roots seek out moisture and can penetrate tiny cracks or joints in sewer pipes, eventually causing blockages and pipe collapse. Our crews remove roots with hydro jetting and can reline pipes to prevent future intrusion.

How much does sewer line repair cost in Portsmouth, NH?

Sewer line repair costs in Portsmouth typically range from $1,500 to $5,000 for standard residential repairs and $5,000 to $15,000 or more for full replacements. Factors include pipe material, depth, length of damaged section, and whether trenchless methods can be used. We provide free camera inspections with detailed, written estimates before any work begins.

How often should I have my sewer line inspected in Portsmouth?

We recommend a sewer camera inspection every 2 to 3 years for Portsmouth properties, or immediately if you notice warning signs like slow drains or sewage odors. Older homes in Portsmouth with clay or cast iron pipes should be inspected more frequently. Regular inspection catches small problems before they become expensive emergencies.
