Brush Coating to Restore Sewer Lines Without Major Digging
When interior pipe surfaces are rough, scaled, or pitted—but a full replacement isn’t practical—this targeted, minimally invasive repair method can be a smart solution. John Shelton Plumbing applies professional epoxy or polymer coatings to rehabilitate short sewer segments, transitions, and fittings. It’s a precise, surface-renewal option that improves flow, seals small defects, and extends pipe life—all with limited access and minimal disruption to your property.
What Is Brush Coating?
This sectional rehabilitation technique cleans the pipe interior and applies a specialized coating to rebuild a smooth, protective surface. Unlike full-length liners used in Trenchless Pipe Lining, it focuses on shorter areas—elbows, wyes, transitions, or sections with heavy scale—making it ideal when only a localized zone needs attention.
When This Method Makes Sense
- Scaled cast iron: Restore flow and reduce snag points that catch debris.
- Minor corrosion and pitting: Seal small defects to slow deterioration.
- Transitions & fittings: Treat complex shapes where liners are difficult.
- Pre-liner prep: Smooth rough sections to support a clean liner install.
Our Process
1) Inspection & Cleaning
We begin with a Sewer Camera Inspection to evaluate the pipe’s condition and determine whether this approach or a full liner is the right fix. Then we perform Hydro Jetting and descaling to create a clean, bondable surface.
2) Masking & Protection
Nearby fixtures and work areas are protected so coatings go exactly where intended—no drips, no overspread.
3) Controlled Application
Using specialized brush systems, we apply one or more coats to rebuild a smooth interior. We work carefully through bends and fittings, ensuring even coverage and proper thickness.
4) Cure & Verification
After curing, we re-inspect with the camera to verify coverage and flow improvements. When needed, we add a final pass to perfect the surface.
Benefits of This Repair Method
- Minimal access required: Work is performed via cleanouts with limited opening of finished areas.
- Improved flow: A smoother interior reduces friction and clog potential.
- Targeted and efficient: Focuses on the exact trouble spot without lining entire runs.
- Budget-friendly: Often less costly than excavation or full-length liners for spot issues.
Brush Coating vs. Trenchless Lining
Both are “no-dig” solutions but serve different needs. The sectional coating method is ideal for localized defects, fittings, or scale removal and resurfacing; trenchless lining rehabilitates longer runs and structurally reinforces deteriorated pipe. We’ll show camera footage and recommend the right option—sometimes a combination works best.
