Trenchless technologies, which have been around for about 15 years or so, have quickly become the most desired method for repairing and replacing old or damaged sewer lines.

However, few homeowners are aware of their benefits — in fact, Angie’s List recently discovered that an incredible 78% of people had never heard of trenchless, or “no dig,” technology.

A trenchless sewer repair can help keep your home’s plumbing, drains and sewer lines in their optimal condition, all without disturbing your landscaping or everyday routine.

Not sure whether or not you should invest in a trenchless pipe repair? Having a professional sewer company perform a sewer line inspection can help you determine whether or not you need to repair your sewer lines. Here’s a look at the top three times when you should consider having a sewer line inspection performed:

You own an older home

Did you know that sewer lines should be replaced after about 40 years or so? If you own a home built before the 1970s, you should have regular sewer line inspections to determine the condition of your pipes and know when it’s time for a replacement. This is especially true for homes built during the 1950s, whose sewer lines are made of Orangeburg pipes that can disintegrate and collapse over the years.

You’re buying a new home

Before you sign any papers or put a down payment on that new home you’re hoping to buy, it’s a good idea to have a sewer line inspection performed on this house’s pipes. This procedure will help detect any problems or damage within the sewer lines, alerting you to any repairs that need to be done. If the house’s sewer lines are a wreck, you will likely be facing costly trenchless pipe repairs soon after moving in.

You suspect your sewer lines are blocked by tree roots

Tree roots are the top cause of cracked, blocked sewer lines. These roots seek out the moisture within your sewer lines and grow within the pipes to reach it. However, you can’t see if a tree’s roots have grown into your sewer lines by looking at the ground — which is where a trenchless sewer line inspection comes in handy.
