A sure sign that you are in need of regrouting will be the cracked, missing or mildewed grout you presently have.
Hopelessly stained, missing or crumbling grout between tiles not only looks bad, but can allow water to accumulate and damage the tile substrate.
Mold and mildew attaches to grout because it is a porous surface, staying continually wet. Mildew is usually black but can appear red, pink or green.
Regrouting and sealing the new grout will help prevent water penetration and staining. This also extends the life of the grout.
It is important to realize that once the regrouting has been completed the next phase is applying a sealant. YOU SHOULD NOT REGROUT WITHOUT APPLYING A SEALANT TO COMPLETE THE PROCESS.
If grout failure has occurred, or your tile walls are leaking, we can isolate and replace the damaged wallboard sections. In order to ensure that your wall is free of mold and mildew, we carefully inspect the region with a moisture detector. Once the wallboard is replaced, the thoroughly cleaned original tiles can often be reused eliminating any need to search for matching tiles.
It is possible in many situations to replace missing or broken tiles. This would be addressed on the basis of availability.
A penetrating sealer is applied to protect grout joints from future discoloration without changing the appearance. This also extends the life of the grout.
Tile floors develop traffic patterns in the grout joints, similar to pathways on a carpet. Developing a regular cleaning schedule increases the longevity of your floor.
