Charlestown Trenchless Sewer Lining — No-Dig Repair Completed Indoors
Boston Pipelining Company recently completed a no-dig sewer rehabilitation in Charlestown, Boston. The 4″ line transitioned to a 6″ main beneath a finished basement, and repeated backups made excavation a risky option. Our team proposed a trenchless sewer repair plan to renew the entire run from inside the home—no jackhammers, no landscaping damage.
Camera Inspection & Plan
We began with a HD sewer inspection to map defects and verify the 4″-to-6″ transition. The video revealed heavy scale, cracking at the hub, and infiltration. With measurements confirmed, we designed a single continuous CIPP liner sized to bridge the transition and restore structural integrity.
Thorough Line Preparation
Before lining, technicians performed aggressive hydro jetting and descaling to remove corrosion and build-up. Proper surface prep is essential for adhesion and maximum flow. Access was created at an interior cleanout so the entire project could be completed indoors, keeping the home secure and dry.
Liner Installation & Cure
We inverted a resin-impregnated liner from the basement access and cured it under a controlled profile, forming a seamless pipe-within-a-pipe across every joint and the 4″-to-6″ transition. Where needed, we finished with targeted epoxy brush coatings on small branches to optimize corrosion resistance and flow.
Long-Term Results
The Charlestown homeowner now has a smooth, jointless sewer with a projected 50+ year service life—completed in a single day and without excavation.
