The short answer
How Brick Reacts to Floodwater
Brick is durable, but it is not waterproof. The clay material is porous, so it absorbs moisture during a flood. This can lead to efflorescence, a white powdery residue, and can weaken the mortar over time. If the water sits for days, the bricks may spall or flake on the surface.
The bigger issue is what happens behind the brick. Water can seep through tiny cracks and around window frames, reaching the wood framing, insulation, and drywall inside. Even if the brick exterior looks fine, the interior can be soaked, leading to rot and structural problems that are not visible from the outside.
Where Floodwater Enters a Brick House
Floodwater does not need to come through the walls. It often enters through the lowest points: door thresholds, garage doors, crawl space vents, and utility pipes. Basement windows and sump pump openings are also common entry spots. Once water is inside, it spreads through the slab or floor joists.
Hydrostatic pressure from saturated soil can push water up through cracks in the concrete floor or slab. That can cause the floor to heave or crack. Even a small amount of water entering can damage baseboards, carpet, and the lower section of drywall, which then wicks moisture upward.
- Check door seals and garage thresholds for gaps
- Seal cracks in the foundation and around pipes
- Install a backwater valve on the main drain
- Elevate appliances and the water heater
- Keep gutters and downspouts clear to direct rain away
- Store valuables and important documents upstairs
What Gets Damaged Inside a Brick House
The interior is the weak point. Drywall, insulation, and wood framing soak up water quickly. Electrical outlets, wiring, and junction boxes can be compromised. Insulation that gets wet holds moisture and becomes a breeding ground for mold. Even if the water recedes, the hidden dampness lingers.
Flooring materials like hardwood, laminate, and carpet are often ruined. Subflooring and joists may need to be dried and inspected for rot. Appliances, HVAC ducts, and the furnace can also be affected. If floodwater was contaminated, everything it touched may need to be discarded for health reasons.
Steps to Take After a Flood
Act quickly to reduce damage. Once it is safe to enter, turn off the electricity at the main breaker if the panel is dry. If you smell gas or suspect a leak, leave and contact the gas utility. Document the damage with photos before moving anything. See a doctor if you feel unwell from exposure to contaminated water.
Remove wet items like carpet, padding, and drywall that touched the water. Open windows and use fans and dehumidifiers to dry the space. Do not try to fix electrical systems yourself. Have a professional inspect the furnace and water heater. In Rogers, keep your shutoff valve location written down so you can stop water flow quickly if a pipe bursts.
When to Call in the Pros
Some flood damage is beyond a quick cleanup. If water reached the drywall, soaked insulation, or affected the electrical system, the pros should handle the drying and sanitizing. They have industrial fans, dehumidifiers, and moisture meters to find hidden wet spots. They can also remove and dispose of contaminated materials safely.
Local water damage pros can assess the full extent of the damage, including the structure and the foundation. They can help you decide what to dry and what to replace. If you have insurance, contact your insurer early. Policies vary, and your insurer decides what is covered. The pros can document the damage for your claim, but they cannot know what your policy pays.

Can brick walls be dried out after a flood?
Yes, brick can dry, but slowly. It can take weeks for moisture to evaporate from the interior. The pros use dehumidifiers and air movers to speed up the process. If the mortar is damaged, it may need repointing. The key is to dry the wall before mold sets in.
Does floodwater damage the brick itself?
Floodwater can cause surface staining and efflorescence. Over time, it can weaken mortar and cause spalling. If the brick is not sealed, water can freeze and crack it in cold weather. A thorough inspection after a flood can determine if the brick needs repair.
Should I replace brick after a flood?
Rarely. Brick is often salvageable if cleaned and dried. The bigger concern is the interior structure. If the brick is cracked or the mortar is crumbled, you may need to repair those areas. A professional can evaluate the condition and advise on the right course.
