If you have cracked shower grout, two potential problems come into play. Water will make its way behind the surface of your tile. This can lead to mold growth that you cannot see but might make you feel ill. Failing shower grout can also lead to water damage by those same means.
Cracks in the Grout: Even a tiny crack in your grout can allow water to seep in and cause damage or mold problems.
Problems Caused by Chipped, Cracked, Crumbling Grout
If you do not get grout repair as soon as possible, these issues can worsen and even cause various health risks. If the grout is crumbling and falling out, you may need a full replacement, whereas grout that is still intact but just cracked may need a simple repair.
Another common cause is cracked or damaged grout. When the grout is compromised, water can penetrate through the cracks and accumulate beneath the tiles, leading to water damage.
A question we're often asked is, “how long should grout last in my bathroom last?” Grout doesn't last forever and has a lifespan of between eight and sixteen years, depending on your upkeep and treatment in your shower area specifically.
Moisture and direct water contact contribute to grout deterioration over time, and eventually, the tiles will crack. This is why you should consider regrouting shower tiles every six months. This is a quick and budget-friendly fix that can restore your bathroom's previous glow immediately.
You can apply new grout right over the top of the old grout. To do this, all you need is a grout removal tool. Use the tool to strike out the old grout, making sure the depth is at least 2mm, which is about the thickness of two dimes stacked one on top of the other.
Moisture that gets behind tiles can cause all sorts of problems. It can destroy the drywall backing, it can cause rot, and it can cause the tiles to begin to fall off if left too long. Worst-case scenario, water damage behind your tiles can lead to mold problems. Mold can be a serious health risk to your family.
One of the tell-tale signs of a water leak coming from a shower valve behind the wall is water stains. If you have an upstairs bathroom, you may notice dried water stains on the ceiling below the shower. Most times shower valve leaks behind the wall are very slow.
If left alone, cracks can begin to appear, causing potential leakage problems. Thankfully, this is where the regrouting process comes in. Maintaining your tiles by regularly replacing old grout is the perfect way to futureproof your wet areas from higher repair costs.
On average, the cost to regrout a shower is between $600 and $2,500 (or $10 to $25 per square foot). Prices hinge on the size of the shower, the type of grout, and how much old grout needs to be removed.
We've done our research and this is what we found out. Yes, you can put silicone over grout. This ensures watertight sealing.
Grout doesn't last forever. You can expect a lifespan between eight and sixteen years. Its lifespan will vary depending on how you treat your shower. Odds are, you have no idea when your grout was installed.
Spray the affected grout with oxygen bleach, chlorine bleach, or hydrogen peroxide, ensuring the solution saturates the stains. Let it dwell for several minutes, then scrub the area. A second application may be necessary for persistent stains.
Visual signs of mold attacks on the bathroom wall include discoloration, peeling wallpaper and crumbling plaster. Mold often grows behind wall tiles, causing these materials to crack or become loose. Plus, gaps in the grout or caulk suggest mold spores have infiltrated the spaces behind the wall.
Specifically, you might find a crack or two—especially in joints where the wall meets the tub, shower, or floor. Grout cracks may develop as a direct result of age, but they can also be products of problems during tile installation or when mixing the grout.
If the damage is sudden, accidental, and comes from inside your home, you're typically protected with a standard homeowners insurance policy. However, you typically won't be covered if the water damage is caused by outside flooding or a neglected repair.
This usually occurs between the floor and wall joints of the shower recess. Up to 90% of showers built onto a stud wall will eventually leak because a gap will occur between the tiled wall and the shower recess floor.
The average cost to fix a shower leak behind the wall is between $200 and $1,000. This wide price range is because some leaks are easy to fix if you spot them early. Others may cause more damage and are in hard-to-access areas, leading to high costs to access the area and deal with any water damage.
Grout naturally shrinks and settles as it dries, which often leads to small cracks. These cracks, even hairline ones, create openings for water to get through.
Splash or spray bits of water on one wall of the shower at a time, checking for leaks as you go. Take a close look at your grout lines before and after wetting them. Be on the lookout for missing grout or obvious holes. These are the likely culprits when you have a leak in a tiled area.
When moisture extends beyond the confines of the shower space, it can seep into surrounding walls, floors, and fixtures, leading to a host of problems such as mold growth, structural damage, and compromised integrity of building materials.
FAQ About Regrouting a Shower
It is generally cheaper to regrout than to retile. Regrouting costs an average of $700–$1,500 while retiling costs $1,800–$5,000 on average.
This really works! The grouting around the tiles in our kitchen and bathroom was looking very tried with several black damp spots. The grout pen covered it all in one coat and was very simple and quick to use. We added an extra coat on the very stained sections and now it all looks like fresh grouting.
