Description:

I need the silicone sealant around my kitchen counter and sink redone. The old silicone has gone black and is peeling away in a few spots, so it needs to be removed and replaced with fresh sealant. It's a fairly small job covering the countertop edge and the sink area. I'd like someone who can bring the right silicone and tools and leave it looking clean and watertight.
