We had back-up of sewage into our home and called a plumber, to snake our sewer pipe through. Upon his snaking through, he stated that we have a sewer brake about 65 feet out of our home. Unfortunatly, this plumber does not do work of sewer pipe replacement. On Demand was recommened to us , by a family friend, as a contact to see, if On Demand would have knowledge of a company that would replace sewer pipes.We checked Angie's List and found good reviews, regarding On Demand Plumbing, although, no sewer pipe replacements or repairs were mentioned.Never-the-less, we called OnDemand, to see, if such a good plumber could recommend a company, to us, which performed this type of service. We spoke with Dan, who told us that OnDemand does perform this type of service and set up an appointment with us very quickly.Dan explained a process to us, which involved running a pipe (such as the once seen on the side of roads, for construction), from the inside of our home ( requiring a hole to be jack hammered through our basement floor, where the access pipe is), through the existing sewer pipe (which would burst away, as the new sewer pipe was pulled through, taking the place of the old pipe. He explained that as long as there would be an opening in the sewer pipe, big enough to fit his camera (hydro jetting?) through, he should be able to pull the new pipe through the existing pipe. When asked about pricing, Dan stated that it would be approximately $10,000.00 to the 65 foot mark. We wanted the whole 110 feet done, so as to not run into such a problem again. Dan stated that it should be no more than $15,000.00 at the most ("Tops").When I called OnDemand Plumbing the following time and asked to speak with Dan, the, very nice secretary, Maureen, told me that she would have to connect me with David who would be handeling this. I was very surprised, Dan never mentioned David to to us.Anyway, Dan and David, both where very nice. David came out to the house, to give me an estimate of $15,000.00 .David came out with some people and hydroplaned through, to see where the break was, in the line, and if they could just get through with their system of pipe and found that they needed to excavate 65 feet out from my home (in the middle of the street). David came to my house, to collect a check for half of the estimated amount, so as to schedule and begin the job. This is when I was informed that that estimate was only up to the 65 feet, not the total of the 110 feet, as originally discussed, as, due to the hydroplaneing they found that they could not pull the new sewer line through, as there was not enough space to allow even for their chain to go and pull the new pipe through all the way. When asked how much it would be to cover the total, 110 feet, David said he had to speak with his excavation guy first( a second smaller excavation would be needed, near where our sewer connects to city sewer), but it would be between an additional $ 5,000.00 - $ 8,000.00 and he would let me know. We o.k.'d the additional $5,000 - $8,000 , however, David never got back to us to let us know the exact amount (would the total be $20,000.00 or $23,000.00???)The job was finaly completed April 2, 2012. We did have a detailed invoice for the initial $15,000.00 and expected to receive a detailed invoice for the complete job. On April 4, 2012, David presented us with one bill in the amount for $7,500.00, which had already been marked paid, a second bill, with the amount for $7,500.00 and then "shell shocked" us with an additional bill for $10,225.00.The presentation of three bills was confusing to us and there was no detailed invoice for the $10,225,00, just the price. We were perplexed that David had neglected to inform us that the total would go more then $2,000.00 over the amount he had told us and that he never even made effort to inform us what the actual amont would be ($20,000.00 or $23,000.00 was expected). We were truely confused by receiving three individual bills, rather then one bill that would reflect that we did pay $7,500.00 and that we still owed $17,725.00 and that the $10,225.00 bill was not reflecting any details. I asked David, before he came, on April 4, 2012, to collect the total, that he would bring us an itemized bill (even then he did not inform us that the amount to be paid did exeed that which we had originally agreed to). David did not have an itemized bill , however, stated that he would e-mail one to me that afternoon. A couple of days later, I e-mailed, requesting the itemized bill and received no answer. I e-mailed again, no answer. I had to call David at the end of April, as On-Demand had also removed our baseboard heater and was contracted to return for reinstallment after our remodel. I reminded David that I had e-mailed him, regarding the details of the invoice in question. He was "surprised" that I had not received it, however, he would send it out with his guy who would be doing the reinstallment of the baseboard heaters. He called me a few days later, informing me that he had "forgotten" to give his guy the detailed invoice and asked to have it brought by at the end, rather then at the beginning of the week. I had, once again given him my e-mail adress to have him mail the detailed invoice and still, nothing. Finaly, I gave it one more e-mail, when David responded , very unprofessional and with a "detailed invoice" the likes of which I have never seen, not impressive at all, but seemingly the "best" we could get from him. We are very disappointed with his manner. Once the customer pays and requests that which is his right, this customer felt that David saw her as a royal pain in the neck, trying to get rid of her.We received a warranty of three years (supposedly the newly installed sewerpipe has a lifetime of 100 yrs.). We can not realy commend on the job, as it is underground. Only the future will tell.We do feel that this solution of sewer pipe replacement was the most cost effective way to go, as it did not require the digging up of the total of the 110 feet, but only two sections of pavement that needed to be excavated (excavation and repavement is most costly), however, we did not get pricing from other companies, as this seemed the perfect solution to our problem. We did get the sense of "good coop/ bad coop" play. We also are not happy over the lack of communicating to us the actual cost of the remaining 45 feet of sewer pipe work. We feel that David did overstep by not communicating the difference of $2,225.00 to us, as we did not agree to this and were then presented with three seperate bills, instead of just one. The fact that I had to chase David down, just to get, what was not even a detailed invoice, but a rough breakdown, and that that "invoice was an e-mail that read : "Here is the breakdown" which, in itself was presented in a most unprofessional way. Had I to do it over again, I would get other estimates and be more careful to assure that the actual cost would be communicated to me, before work began/conntinued. The buisness manner of this deal, on behalf of OnDemand was most disapointing, although, I would like to say, that their former secretary, Maureen (apparently no longer works there now) was just a real sweetheart, very pleasant to deal with and she was truely, in her position very professional. I would definatley recommend to check out other companies which may use the same and/ or other system of sewer pipe replacement I would furthermore recommend to be sure that the contract was signed for the total of the work, with good understanding and communicating of the actual cost for the total of the work to be done, to avoid surprises. Should we experience a problem with our sewer pipe within the time of the Warranty (3 yrs), I will have to call OnDemand back, however, I would not hire them for any other issues. They have not earned my trust, that's for sure!!!
