There is usually very little indication when you have problems with your sewer line. In some cases, the sewer collapses in on itself, blocking the line and that can lead to problems with your waste; either draining from a sink or flushing your toilet. However the problem comes about, a sewer line replacement can be a big job, and that usually means expensive!
It is virtually impossible to give a definitive answer on this; there are so many variables, all of them can have a significant impact on the final price of the job. However, we can give you some information to think about.
A traditional type of sewer line repair can be extremely labor intensive;
let’s assume that you have located where the problem is (and that
can be tricky!), you then have to access the sewer line. This usually
involves a good few man hours of labor to dig around the line, and that’s
assuming they are digging through dirt.
Labor can be very expensive!
Depending on the job, it may be possible to reline your sewer.
Relining is a reasonably new method of repairing a sewer line, but it does depend on what damage there is and why you actually need replacement.
Some pipes can be fixed, water tight and ready to go in as little as 30 minutes.
You should always take professional advice. Talk to two or three different companies and see what they offer and how best they think to complete the job. Price is obviously a consideration, but cheapest doesn’t necessarily mean best value, equally, most expensive isn’t a guarantee of quality.
