I had a marble worktop installed in my new kitchen in August 2023. I noticed a couple of dings that had been filled when it was fitted as the colour was off so the fitters came back and redid them. I've since had them back as the silicon all along the sink up stand failed and was coming away.
About 4 weeks ago while on the phone (the rare occasion I paused in the kitchen) I noticed a small loose slice of marble under the worktop directly below the kitchen tap. Upon close inspection there is also a crack directly in-front of the tap running from the tap hole to the edge of the worktop and down through it.
I asked the supplier to come and look, they were busy before Christmas and sent one of their fitters this week who immediately said it wasn't cracked it was a vein and he couldn't feel a crack. I demonstrated I could with my nail and then he offered to polish it and said it would be gone in minutes. I declined the offer as I think its in a place that will now be susceptible to water damage and there would have been a risk of damaging my Qettle tap and its just a patch repair on an expensive worktop. He was insistent on going to his van to get the tools to polish it and then my DH entered the room and we had the same conversation and declined the polish fix and I asked him to get the sales guy to call me as I don't want a patch fix on this.
After they left I went thought my photos taken on the day of install and have one when it was first installed with no crack, then one after they drilled the tap hole and the crack is visible, as the photo was taken further away I had to view it on my tv and zoom in to see the detail, it shows the crack after the tap hole was drilled. The photos are time and date stamped. The installers spent quite a bit of time huddled over the sink & the island polishing various things on the day, I tried to stay out of the way and now feel like I've been conned. They also applied a lot of liquid sealant and told me to leave the worktops for 24 hours to seal them.
The sales guy left me a v/m yesterday, could barely hear him, don't know if that was deliberate but stating he would have noticed the crack if it had been there when they fitted it and it must be something that's happened since. He suggested using a repair service, I don't want this repairing. He is yet to see my photos. Do you think IBU to ask for a refund?
