Can water damaged cabinets be repaired? ›

Whether or not you can repair water-damaged cabinets depends on the extent of the damage. If only the cabinet finish is stained or peeling, you may be able to get away with refinishing or refacing your cabinets.

Replace a Swollen Vanity Base or Other Section

If the entire board swells up, you could replace the base rather than the entire unit. When only a portion of the base or another part of the cabinet's structure has water damage, you may be able to sand it down or cut a small section out and repair it with wood filler.

Minor water damages on wood tables can be reversed fairly easily. You can remove stains and light surface damage with a sandblock, then repaint and re-varnish the wood surface. For swollen and rotten wood, you can cut away the damaged parts and use a wood filler as long as the affected area isn't too much.

Efficient drying methods such as air drying and employing dehumidifiers are crucial. Air drying allows natural evaporation, while dehumidifiers expedite the process, preventing further damage caused by prolonged moisture. Thorough drying is vital to prevent warping, mold growth, and structural compromise.

Water damage can wear away finishes, it can seep into cracks, and it can cause mold growth. But the worst thing that water damage can do is disintegrate your cabinetry right out from under your countertop. Most kitchen cabinets are made from particle board of varying density.

Applying a sealant like polyurethane on the corners of your vanity can make it virtually waterproof, with water unable to penetrate the surface of the material at all. You can do the application yourself using store-bought sealant either as a spray-on or liquid.

You could achieve a reasonable repair job by sanding back the swollen area until it's flush with the rest of the door. You can then fill the chipped laminate edges with Builder's Bog and sand it back to form crisp corners. Once everything is looking good, you can use the laminate primer and then paint your cabinetry.

Completely Dry the Wood

While the wood flooring appears dry, water could have penetrated throughout the plank as you can't remove it with the wet vacuum. Use a dehumidifier placed at the highest setting possible to dry the floors. Place it in the center of the room and leave it on for at least 24 hours.

If water-damaged wood on the outside of your house doesn't provide structural support it can often be repaired with auto body filler to avoid removing the whole piece. Clean out the rotten material so the filler will stick to good wood before mixing the filler putty with the supplied hardening cream.

What do you spray on wood after water damage? ›

Mold prevention sprays are specifically designed to prevent mold growth after water damage. These sprays contain ingredients that kill mold spores and prevent them from growing. Look for a mold prevention spray that is safe for use on different surfaces, including walls, floors, and furniture.

In general, dry rot can appear between 7 and 10 days after the wooden element has received enough dampness. If the spores are older, they may take longer to germinate. In terms of wet rot, establishing a regular timeframe for its onset is difficult since there are more factors at play.

How to kill the fungus that causes wood rot. Boric acid (borate) is one of the most effective fungicides for use in treating wood rot. It can be applied to wood during construction to prevent future rot, or as a treatment to stop an active decay fungus from growing.

Once you've removed the crumbling wood, use a wet rot wood hardener and apply it to the wood with a paintbrush. Don't be afraid to lay it on thick and leave it to soak into the wood. When the hardener is dry, the rotten wood should be healthy again.

You could achieve a reasonable repair job by sanding back the swollen area until it's flush with the rest of the door. You can then fill the chipped laminate edges with Builder's Bog and sand it back to form crisp corners. Once everything is looking good, you can use the laminate primer and then paint your cabinetry.

In severe cases of water damage, hardwood floorboards may raise up from the floor by 4-5 inches. In such instances, it is likely that the hardwood floors will require complete replacement.
