Pipe repair without the excavation
Trenchless pipe lining installs a new pipe inside the old one. A resin-saturated liner is inserted through an existing access point, pressed against the host pipe and cured in place, leaving a smooth, jointless pipe that seals cracks, root intrusion and corrosion. The building stays open, the parking lot stays intact, and the work that used to take a week of digging takes a day or two.
Progressive has been a commercial plumbing contractor since 1983 and has cleaned and repaired pipelines from three inches to sixty inches in diameter. Lining is the natural extension of that work: we already inspect and clean the pipe; now we rehabilitate it in place.
The trenchless workflow
- Inspect. A camera inspection maps the line, locates the defects and confirms the pipe is a candidate for lining.
- Clean. Our truck-mounted combination units and high-pressure jetters, with an extensive set of nozzles and saw and chain cutters, strip years of grease, scale and roots so the liner bonds to sound pipe. The same equipment serves municipal sewer and storm drains, industrial waste lines, manholes and lift stations.
- Line. CIPP or UV-cured liner is installed and cured in place. Lateral connections are reinstated robotically where required.
- Verify. A post-lining camera inspection documents the finished pipe for your records.
Where lining pays off
- Sewer laterals and mains under buildings, slabs, parking lots and landscaping: our Zero-Dig sewer repair.
- Vertical stacks, vent stacks and roof drains in multi-story buildings, where opening walls on every floor is not an option.
- Cast iron, clay, Orangeburg, concrete and PVC pipe: see lining by pipe material.
- Hospitals, hotels, schools, restaurants, office and industrial buildings that cannot close for a dig.
Why Progressive
One licensed contractor handles inspection, cleaning, lining, any necessary spot excavation, and the plumbing, HVAC and electrical work around it. We use professional trenchless lining systems and cure our liners to the manufacturer's specification, and we document every job with before-and-after video.
Frequently asked questions
How long does a lined pipe last?
Cured-in-place liners are engineered for a service life measured in decades and typically outlast the original pipe. Ask us for the design life and warranty terms of the specific liner system we propose.
Does lining reduce the pipe diameter?
Slightly, but the new pipe is smooth and jointless, so flow capacity is usually equal to or better than the old, rough, root-obstructed pipe.
Can every pipe be lined?
No. Collapsed pipe, severe offsets or bellies need a spot repair first. The camera inspection tells us, and we quote the combination that fixes the problem.
How long is the building disrupted?
Most lining jobs are completed in a day or two with the building occupied. Water use on the affected line is limited during the cure, and we schedule around your operations.

Joe Oliveira stopped by my home, took time to understand the problem that I was having with the unit, went back and discussed the issue with his team of experts and had a detailed work order sent to me with in a day. … Based on the experience that I have had with Progressive Plumbing, Heating & Air, Electrical, I will HIGHLY recommend them for HVAC install and maintenance.
