Duluth sanitary sewer repair estimate

So we received a while back information telling us that we would need to repair our existing sewer line because of inflow and infiltration along with other neighbors. The city of Duluth does provide a grant for these projects (80 percent of $4,000 to $5,000). We were looking at lining the sewer line rather than excavating it.

However, we called the same company (they were the lowest bidder for the project) as our neighbors did and got an estimate that was nearly $2,500 more than the estimate they gave them!!!

I’m sure others in Duluth have dealt with this, or are dealing with the same situation as myself. Ideally I would like to get a ballpark figure of the expense and the company any of you chose for this project. Needless to say we will be calling around.

We had ours replaced a couple years ago, and I'd have to find the receipts, but I think the estimate was $5,000 to $6,000. They ran into complications - not enough slope from the house to the sewer line in the street - and we ended up at almost $8,000 if I remember correctly. I think it does vary quite a bit depending on where the line comes out of the house and what they have to do to get it put back together. They had to dig up and replace  all of the sidewalk leading up to the house and dig up quite a bit in the basement to get to a solid pipe to connect to.

Line up the grant money with the city before they start working. I almost missed out on that because they were in the middle of the project when I found out about it, but got lucky.

We used Waters Excavation. They were good, only problems we had were that they got really busy and it took a long time for them to get back to finish up the sidewalk and dirt, and the grass seed they put down was really cheap and crappy. It died the next year. Still can't get much to grow in the dirt they put down.

But I can send just about anything down the toilet now.

I had an estimate for lining done, the cost at the time was quouted as $100 per foot. So, if your sewer line is 25 feet longer than your neighbor's, the $2,500 would make sense. It appears there are a couple of new companies to choose from.
For whatever reason, my sewer line comes out the side of my house instead of the front and is 85 feet long rather than the "standard" 50 feet of sewer line coming out of the front of my neighbor's house.

We were looking at lining as well, and I was surprised to discover that it was about as expensive as a new PVC line. But we wanted to avoid digging up the yard. Eventually, however, we went with Carlson after we realized that the water line was as old as the sewer line (1924), and if it ever went, we'd have to dig up the yard anyway. Better to replace both at once while the city was helping foot the bill. Once the crew got to work on it, they discovered they could run the new lines (water and sewer) right through the existing lines so no digging up the yard after all--just a hole by the house and another by the street. The best of all worlds. We were very happy with their price, crew and the work. Best of all: they finished a couple days before the floods last year. I shudder to think what would have come up into the basement if that old sewer line hadn't been replaced.

I am glad to view such a great article. I found this blog by accident. Really glad I did though, I'll be back from now on. It can be difficult to find good blogs nowadays. Found one here though by the looks of things.
