Gap Sealing Products

           There are several options for filling gaps in your floorboards. These include traditional fills such as               silicone, wood glue mixed with sawdust, and expanding spray foam. There are also newer products

on the market that resemble tape and are installed inside the crack itself, making them invisible

from the outside.
