Sewer Relining Services in the Greater Seattle Area A Smart, No-Dig Solution for Lasting Sewer Line Repair

When your sewer line starts leaking, cracking, or backing up, replacing it doesn’t have to mean tearing up your yard. At Greenwood Heating & Home Services, we offer sewer relining—an innovative, trenchless solution that restores your existing sewer pipe from the inside out.

Our advanced technology allows homeowners across Seattle, Bellevue, Everett, and surrounding areas to get long-lasting results without the mess, expense, or disruption of traditional excavation.

What Is Sewer Relining?

Sewer relining (also known as Cured-In-Place Pipe, or CIPP) is a trenchless repair method that creates a brand-new, seamless pipe inside your old one. Using specialized equipment, we insert a resin-coated liner into the existing pipe, inflate it, and cure it in place with hot water, steam, or UV light.

Once cured, it hardens into a durable, jointless “pipe within a pipe” — effectively sealing cracks, preventing leaks, and restoring full function for decades.

Why Choose Sewer Relining?

No Major Digging or Damage

Traditional sewer replacement means digging trenches through your yard, garden, or driveway. With sewer relining, we only need small access points—saving your landscaping, hardscaping, and peace of mind.

Tankless Water Heaters 

Tankless units, also called on-demand water heaters, heat water directly as it passes through the unit, eliminating the need for a storage tank. They are more energy-efficient than tank models and provide endless hot water on demand.  

Long-Lasting Results

Relined pipes are designed to last 50+ years and resist corrosion, root intrusion, and soil shifting—common issues for homes in the Pacific Northwest.

Cost-Effective

Because there’s no major excavation or property restoration required, sewer relining typically costs less overall than a full replacement.

Faster Repairs

Most sewer relining jobs can be completed in one to two days, minimizing disruption to your home and routine.

Environmentally Friendly

Relining uses existing infrastructure, reduces waste, and avoids damaging soil and plants—making it a greener, smarter choice.

Signs You May Need Sewer Relining

You might not see your sewer line, but you’ll notice the symptoms of a problem:

  • Frequent or recurring drain backups
  • Gurgling sounds from toilets or drains
  • Sewage odors in the yard or basement
  • Soggy or unusually green patches of grass
  • Slow-draining sinks, tubs, or showers

If you notice these warning signs, callGreenwood Heating & Home Services. We’ll perform a video camera inspection to pinpoint the issue and determine if sewer relining is the best fix.

Our Sewer Relining Process

  • Camera Inspection – We inspect your existing sewer line using a high-resolution camera to identify cracks, roots, or damage.
  • Pipe Cleaning – The line is cleared of buildup, roots, and debris to prepare for relining.
  • Liner Installation – A flexible liner coated in epoxy resin is inserted and positioned inside the pipe.
  • Curing & Sealing – The liner is inflated and cured in place to form a smooth, jointless new pipe.
  • Final Inspection – We re-inspect the line to ensure it’s sealed, smooth, and functioning like new.
