What Causes Water Damage On Baseboards

Baseboards conceal the spot where the carpet meets the wall and shield your walls from scratches caused by shoes and vacuum cleaners. Water damage on baseboards might be a sign of more serious plumbing problems in your home because they are so low to the ground. Water leaks must be identified as soon as possible to prevent any further damage. 

Let’s delve and find out the signs what causes water damage on baseboards and their signs.

What Causes Water Damage On Baseboards?

Flooding in the home is the primary factor causing water damage to baseboards. It should come as no surprise if your baseboards have water damage or if there has been flooding throughout your house! What causes water damage on baseboards, besides the obvious answer? What happens if, as far as you know, there hasn’t been any flooding?

Baseboard water damage can occur when slow-flowing leaky pipes behind walls leak water. This is a very concerning scenario since there is a chance that the leak will remain hidden for a long period and that mold will grow in the area behind your walls. Everyone who enters the area is at risk for respiratory-related health problems due to the growth of mold.

Everyone’s health is at risk if there is any water damage on baseboards or anywhere else on your property. Therefore, any damage must be addressed right away.


Signs of water damage on baseboards

Look for these signs of water damage on baseboards while checking your house or a potential purchase:

Developing Mold And Mildew

Mold in the house is news that none of us wants to hear. You probably have mold if you start to smell musty, especially in a small area.

Mold removal services will help you restore your home to its former state.

Paint Or Wallpaper Peeling

After water damage, paint or wallpaper may begin to peel or flake off. Water and excessive moisture will eventually seep into the glue of your paint or wallpaper, causing it to break apart. Pay attention if you notice any unusual spots surrounding your walls, particularly after a significant downpour or a plumbing crisis.


You shouldn’t disregard the stain that is spreading across your baseboards. Spreading stains should be taken seriously. Water gradually stains and damages baseboards, ceilings, and walls.

You should hire a professional if you see that your baseboards are becoming gray, brown, or yellow.

Unstable Wall Interaction

There’s a problem if your baseboard is separating from the wall. Water damage that is not visible is probably the cause of baseboards that warp, crack, and break away from the wall.

For a comprehensive inspection, give your local water damage service a call.

Warping Or Swelling

A repair is useless if you notice that a baseboard has warped or swelled. It will be necessary for you to install a new baseboard. It is not possible to fix the wood or fiberboard because it has absorbed so much water.


Things To Think About Before Fixing A Water-Damaged Baseboard

If you want your project to go forward more quickly and smoothly, take these suggestions into account.

Determine how the baseboard got wet and damaged before taking any further action. The problem must be resolved at its root as soon as possible. After resolving the leak, you can proceed with baseboard repair.

Generally speaking, to inspect behind the walls for mold and moisture damage, you’ll need a professional water damage service. With household fans and humidifiers, proper cleanup isn’t always achievable. Usually, stronger commercial models are required.


7 Steps To Fixing A Water-Damaged Baseboard

For this project, you will require intermediate carpentry skills. You’ll need roughly 45 minutes to complete it, plus additional time for painting and other tasks. Along with these, you’ll need a backsaw, miter box, pliers, finish nails, putty knife, and hammer.

Step 1: Keep The Current Base Shoe.

You shouldn’t remove the nail if you wish to preserve the current base shoe located at the base of the baseboard. Rather, use a nail set to push the finishing nail completely through the base shoe.

Step 2: Take The Baseboard Off

Using a putty knife and a pry bar, pry off the baseboard and top molding. Using your pliers, remove the nails.

Step 3: Ensure That The Wall Is Dry

Make sure that the plumbing leak has been fixed and that the wall behind the baseboard is completely dry. Prior to moving further, take note of this.

At this point, you should contact a water damage professional to ensure that there isn’t mold growth or water damage behind your walls—which is quite likely. Hazardous health conditions may result from this.

Step 4: Take Measurements

Take careful measurements. To ensure a snug fit, add 1/16-inch to the overall length and spring the molding into place.

Step 5: Cut The Baseboards

A cheap miter box and backsaw will work well for cutting the baseboards. Remember to measure twice or more before cutting.

Step 6: Attach The Baseboard

Make pilot holes and insert the finishing nails into the sole plate. Adhere the outer edges with glue.

Step 7: Put The Foundational Shoe Molding In Place

At the base of the baseboard, position and place the new or recovered base shoe molding. Make pilot holes and attach them to either the baseboard or the floor, but not both! Any ugly floor imperfections will be concealed by the base shoe, which also protects the baseboard.



Water damage nearly often results in unfixable issues, making baseboard repairs challenging. This is especially the case if they are wrapped or swollen. Replacement is the sole option in those circumstances.

More importantly, though, if you have this problem, you should contact a water damage restoration professional or a plumber with expertise in dealing with water damage. The inside of your walls may have more or larger problems than your baseboards.

For this reason, understanding what causes water damage on baseboards, what signs to look out for, what to take into consideration before fixing it, and how to fix it is essential.
