Commercial Drain Cleaning

Commercial drain cleaning designed for business operations. We schedule service around your hours, clean every drain in your facility, and maintain records for health and code compliance.

Sewer Line Cleaning

Professional sewer main cleaning using high-pressure water jetting and cable machines. We clear stubborn blockages and flush the entire line to prevent future backups.

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.

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.

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.

24/7 emergency drain clearing and repair when you cannot wait until morning. Our crews carry everything needed to clear blockages, stop overflows, and restore drainage immediately.

Sewer Camera Inspection

Non-invasive sewer camera diagnostics using waterproof HD cameras. We record footage, mark problem locations, and provide you with a detailed report of findings and repair options.

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.

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.

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.

Industrial-strength hydro jetting for sewer mains, drain lines, and commercial plumbing. High-pressure water cuts through the toughest obstructions and leaves pipe walls clean for maximum flow.

Frequently Asked Questions

Answers to the most frequently asked sewer and drain questions from Dover property owners.

How quickly can you respond to a sewer emergency in Dover?

We provide 24/7 emergency sewer and drain response throughout Dover and surrounding New Hampshire communities. Our crews typically arrive on-site within 60 to 90 minutes of your call. Sewer backups are health hazards that worsen quickly, so rapid response is critical to protecting your property and your family.

How do you diagnose sewer problems in Dover 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 Dover property without any excavation.

How long does a drain cleaning take in Dover?

Most residential drain cleaning jobs in Dover, 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 is hydro jetting and when is it needed in Dover?

Hydro jetting uses high-pressure water — up to 4,000 PSI — to scour pipe walls clean, removing grease, scale, tree roots, and mineral deposits. It is recommended for Dover properties with recurring clogs, heavy grease buildup, or sewer lines blocked by roots. It is the most effective way to restore full flow to your pipes.

What causes recurring drain clogs in Dover homes?

Recurring clogs in Dover 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.

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

Most standard homeowners insurance policies in Dover 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 Dover homeowners understand their coverage and provide documentation for claims that do apply.
