5 Questions to Ask Before Hiring a Trenchless Sewer Repair Company

A trenchless repair should solve the problem with as little disruption as possible while giving you a long-lasting pipe system. That is especially important when the work affects an occupied home, a busy restaurant, a commercial property, a medical building, or a parking lot where downtime can interrupt daily operations.

As you compare companies offering trenchless pipe repair in Phoenix, AZ, these five questions can help you separate qualified contractors from those with limited experience.

Question 1: How Long Have You Been Doing This Work?

Pipe technology continues to evolve, so it’s important to choose a company that stays current with modern trenchless repair methods. Ask how many years the company has handled sewer line repair for buildings like yours, not just homes. Commercial jobs come with tighter timelines, code requirements, and higher stakes. A crew with real years behind them has already solved the problems your pipes might throw at them.

Question 2: Are Your Technicians Certified and Trained?

Certifications show that technicians have completed formal training and demonstrated their knowledge through industry-recognized testing. Ask which certifications the crew holds and how often their training gets updated. According to the Environmental Protection Agency, aging pipe systems account for a large share of sewer failures nationwide, so proper training in pipe inspection and repair methods directly affects how long a fix lasts.

Look for credentials such as:

• NASSCO certifications
• Certified Pipelining Inspectors
• Manufacturer training
• No Dig installation certifications

Professional training also helps crews perform repairs efficiently while reducing disruption around occupied properties and active businesses.

Question 3: Can My Building Stay Open During the Repair?

Digging up a parking lot or tearing into a restaurant floor isn’t always necessary. One of the biggest reasons trenchless pipe lining exists as a service is to fix damaged pipes from the inside, without breaking through concrete, landscaping, or flooring. Ask if your building can stay open and operating while the work happens. For occupied spaces, this question alone can save weeks of lost business.

Question 4: What Repair Method Fits My Pipe’s Condition?

Not every pipe problem needs the same fix. A good contractor should explain:

• Whether the damage is a crack, a collapse, or root intrusion
• How pipe material and age affect the repair choice
• Which method offers the longest lifespan for your specific pipe

Question 5: Do You Provide Written Estimates and Warranties?

Get everything in writing. Ask what the warranty covers, how long it lasts, and what happens if the same problem returns. A written estimate also protects you from surprise charges once the crew starts digging or lining.

FAQ

Can trenchless repairs work on older pipes?

Often, yes. Many aging clay, cast iron, and concrete sewer lines can be restored if the existing pipe still provides enough structural support. A camera inspection determines eligibility.

Will businesses need to close during repairs?

Not always. Many trenchless projects are planned to reduce disruption, allowing homes and many commercial properties to remain in use while work is completed.

How long does a trenchless repair last?

When installed correctly using approved materials, modern trenchless systems can provide decades of service. Industry testing has shown many cured-in-place pipe systems are designed with service lives of 50 years or more.
