What to Look for in CIPP Contractors

Choosing a CIPP contractor, is often something that people do only once in their lives. The lifespan of CIPP is 30-50 years, in ground. This lifespan also depends on the type, size, and the material make up the pipe. With such a big investment at stake, you should make sure you’re choosing the CIPP contractors who will give you the best service for your money. There are four main ways to measure CIPP contractors. Their certifications, their experience, their evaluations, and their equipment. Pay attention to these factors and you’ll always pick the best CIPP contractors. 


CIPP training is not yet standardized by the government, but that doesn’t mean that you can skip out on the certification process. Every CIPP contractor had to be trained somewhere. If they’re installing CIPP but haven’t bothered to get any kind of professional certification, consider what they may be hiding. 


You don’t want to be the first cured in place pipe that the company has ever installed. CIPP has been building in popularity for decades. Plenty of opportunity exists, for contractors to use CIPP on pipes before working on your pipes. 

However, this isn't always the case. There is the chance that you really are the first customer. If CIPP has only recently become an option in your area, then it’s possible the company hasn't really worked with CIPP before. In this case, you should ask for the work history of the owner(s) and contractors. If there’s no one on the crew who’s installed CIPP, then it’s time to worry. 

Honest evaluations

CIPP contractors want to offer competitive estimates as much as anyone does. However, most CIPP estimates cannot be conducted until after a video inspection of the pipe has been completed. There are some pipes that are simply too damaged for CIPP to take. In these instances, the contractors will have to discuss your other options with you. If you still really want trenchless pipe repair, pipe bursting may be an option. You want to hire CIPP contractors who are honest about the limitations of an initial inspection. A complete video inspection is needed to confirm that a pipe is ready for cured in place pipe treatment. If your contractors want to insist that they “know” the pipe is fine without checking, move on to the next ones. There’s no reason to rush into anything without getting a good look at it first. If CIPP contractors offer you a rough estimate, that’s fine—so long as it’s clear they’re basing it off what the pipe replacement will cost with no problems. 

Cutting edge equipment

Large CIPP pipes may need a refrigerated truck to get them from point A to point B. The woven liners have to be kept chilled so that the epoxy or resin doesn’t run or stick. If you’re not seeing any real equipment, skip the contractors. CIPP isn’t just an offshoot business. It requires dedication and the right tools to get the job done. 

Their evaluations and equipment will tell you what kind of workers your potential CIPP contractors are. Their certifications and experience will tell you what they did to get there. Look for a good balance of all four properties to get the best CIPP contractors working on your pipes.
