My crawl space was flooded, so I crawled in and took out the sump pump. I bought a new sump pump on Amazon to replace it. Exactly the same model. My drainage system had been completely replaced by a very reputable company twenty years ago. I called Bob Oakes to install the sump pump that I had purchased. I planned to have the sump pump installed ASAP to get rid of the water and then later to hire an external sewer company to have some of the gutter/down spout run off diverted externally through PVC pipes to a dry well to be built in my back yard. The Bob Oakes estimate was $1300 for sump pump installation only (I supplied the $700 sump pump myself). The estimator was professional, knowledgeable and helpful, but I was shocked at the price. The estimator told me that my sump pump well was not up to code and that they had to calibrate this and that with the sump pump. I replied, but I had purchased and was furnishing the sump pump myself. He said that it would have been $2000 if they supplied the sump pump. I decided not to go with them and to have the external sewer company install my sump pump when they built the external gutter/down spout drain piping system to a new dry well outside -- thinking I might be able to save some money by combining the jobs, even though I would have to wait. When the external sewer company came, they said they would charge me $300 to install the sump pump. When I asked about the well not being up to code, they said it was fine and that my system was originally designed and installed by one of the best companies that was considered the Cadillac of the field. The external sewer company installed my sump pump and ran piping for three gutter downspouts to a newly built dry well in my backyard and charged $2300 for everything, including tax. If you can go with a specialized construction company, use them and avoid the plumbers. The plumbing fees can be so outrageous.
