Business ProfileforJER'S Custom Tiling & Flooring

We contacted JER"S Tile and Flooring after we received a referral from another contractor that we had recently used. We asked for a quote to replace the existing backsplash tile in our kitchen ( a total area of 19sqft. He came over and explained his scope of the work with included removing the old tile, replacing the drywall, as he explained it's pretty hard to get the old tile out without damaging the drywall. He then sent us a quote for $1257 with GST included in that amount. We booked him and he showed up with a "helper" and stated the helper would be doing the job. He then went on to say they would be putting the new tile over top of the old tile, which we had not originally been told. We realized that this would take much less time and less work involved (1/4 time and labour). We went back to him and said the scope of the work had drastically been reduced with the method they used ( didn't ask if we were ok with the new method but rather just said this is what we are doing) He said he would supply us with a new quote and went on to say that he does not charge by the hour but rather the tile/square foot. The tile we had picked was a moscaic 12 x 12 piece. He used 20 tiles to complete the job. We sent him a picture of the tile we had purchased and he did not say it was a more complicated tile to work with at any time, nor did the installer say it was hard to work with. After receiving the revised invoice we still feel we are being grossly overcharged. We have since called around to more than 4 other companies and provided them all the info to do the exact same job and all the quotes have come back at about $600 **** When we informed him of our concern he only revised the quote by reducing it $210.00 from the original amount of $1257.89. This contractor is charging us twice the amount and when we told him of this concern, he would not reduce it. His cost works out to $50 per square foot for this job. We have not paid this contractor at this time.
