Q: I’m interested in putting laminate flooring in my family room but I have one problem. We have a limestone fireplace, and there is about a 2 inch variation at the bottom of it. So obviously I cant just lay the flooring up next to it. What would be some of my best options?

Here is a picture of Chase’s fireplace. You can see the variation he mentions from the different sized and shaped limestone pieces.
A: There are two options you can do here. If you are fairly handy with a jigsaw and scribing, then I would suggest scribing each plank to fit around the shape of the stones in the fireplace. This is a fairly common practice in commercial installations, fitting the planks to the stone. As long as the run from the fireplace to the wall on the other side of the room is not very long, you should have little problem with expansion, just leave a very small gap at the fireplace and a proper expansion gap at the opposite wall. This will require a bit more planning, but the benefit is that you are not affecting the stone of the fireplace, so if you change your floor the fireplace is untouched. Don’t forget to use a silicone based caulking between the fireplace and the scribe. make sure it is silicone and not latex-based, especially if you choose a colored caulking, which tends to look better, as the latex based colored caulks can bleed color into the stone.
Although this method will take a bit of time, a couple of hours or so to scribe and cut all of the planks to fit the fireplace well, it will provide the optimal appearance and utility should you later decide to change out your floor.
Another option would be to treat the fireplace similar to a door jamb, and cut a relief into the stone so that the laminate can slide underneath with a hidden expansion gap. I will stress that I don’t suggest this method as it will be messy and once done, changing floor coverings while keeping the fireplace looking good is tough.
To undercut the fireplace, you will want to use a pocket door saw with am abrasive blade, preferably a masonry blade or stone cutting blade. Measure for just a bit higher than the final height of the floor plus underlayment, scribe a line and then begin your cut work. While cutting, its a good idea to have someone there helping by having a shop vac on near the exit area of the saw so that all the dust that will be thrown out will get sucked up. Masonry cutting causes a lot of dust and unlike saw dust, it does not settle quite as quickly so without a good vacuum it will look like someone was blowing flower all over the place. Again, I stress that this is not the method I would suggest because it will permanently change the fireplace and cause quite a of a mess.
