If your University Place bathroom has brick walls, a tiled shower, or a tub with a liner, moisture damage is likely hiding behind the surface. Cracked grout, peeling caulk, or efflorescence (white mineral deposits) on brick are early warnings. Medina Bathroom Remodeling specializes in repairing these issues in older homes, where poor drainage, original liners, and Puget Sound humidity accelerate decay. We replace failing liners, repoint brick, and waterproof properly to stop recurring problems. Skip the temporary fixes; call us for a lasting solution tailored to University Place’s climate and housing stock.
1. What is efflorescence on bathroom brick, and why does it mean your University Place home’s masonry is failing?
Efflorescence, the chalky white crust on brick or mortar, is a dead giveaway that moisture is seeping through your bathroom’s masonry. In University Place, where older homes often have solid brick or concrete-block walls with thin plaster coatings, this happens when humidity from showers or leaks travels through the brick and deposits soluble salts on the surface. Unlike cosmetic issues, efflorescence signals deeper problems: cracked mortar, failing waterproofing, or even structural damage from freeze-thaw cycles in our mild but damp winters. Medina Bathroom Remodeling sees this most often in bathrooms with original 1950s–1970s brickwork, where the mortar was never designed to handle modern shower spray. We start by pressure-washing the brick to remove surface salts, then repoint the mortar with a waterproof sealant and install a new moisture barrier behind the tile. For severe cases, we may recommend replacing the brick veneer entirely, something DIYers can’t do safely without compromising the home’s structure. the National Association of the Remodeling Industry (NARI)|https://www.nari.org/)) recommends addressing efflorescence within 6–12 months of noticing it, or the salts will etch into the brick permanently.

2. How do you know if your University Place bathroom’s tub/shower liner is rotting, and why can’t you just paint over it?
A rotting tub or shower liner in a University Place home isn’t just a cosmetic issue, it’s a health hazard. Look for these signs: soft, spongy edges on the liner; black mold growing along the seams where the liner meets the wall; or a musty smell even after cleaning. Older homes built before the 1980s often have fiberglass or thin acrylic liners that weren’t designed to handle the humidity and occasional leaks common in Puget Sound bathrooms. Painting over a damaged liner won’t fix the rot; the moisture will keep breaking down the material, and mold will spread into the walls. Medina’s approach is to remove the old liner completely, then install a new, thicker liner with a sealed perimeter to prevent future leaks. For bathrooms with brick or tile walls, we also add a waterproof membrane behind the liner to stop moisture from seeping into the masonry. If the subfloor is damaged, we replace it with moisture-resistant plywood. The cost ranges from $800 to $2,500 for a full liner replacement in University Place, depending on the bathroom size and whether additional repairs are needed. ENERGY STAR notes that proper waterproofing can reduce long-term humidity-related damage by up to 70%, worth the investment for older homes. Learn more about get in touch for a free estimate.
3. Why does my University Place bathroom’s grout keep cracking, even after resealing?
Grout in University Place bathrooms cracks for two main reasons: movement in the tile substrate (often due to poor installation or shifting brick) and moisture wicking into the grout lines. If you’ve resealed the grout and it’s still cracking within a year, the issue isn’t just surface-level. Medina frequently encounters this in bathrooms with original 1960s–1970s tile, where the thinset adhesive was often applied too thinly or over uneven surfaces. The solution isn’t just regrouting, it’s addressing the root cause. We start by removing the old grout and inspecting the tile and substrate. If the brick or backer board is shifting, we install movement joints or a flexible membrane before regrouting with a sanded, epoxy-based grout that resists cracking. For showers, we also add a waterproof membrane under the tile to prevent moisture from getting trapped behind the grout. The upfront cost is higher ($1,200–$3,500 for a full regrout in University Place), but it eliminates the need for repeated repairs. the National Kitchen & Bath Association (NKBA)|https://nkba.org/)) recommends using epoxy grout in wet areas like showers, as it’s 10 times more water-resistant than standard cement grout. We cover this in who we are and how we train.
4. Can you repair crumbling mortar in University Place brick bathrooms without tearing out the tile?
Yes, but only if the damage is isolated to the mortar joints, not the brick itself. Crumbling mortar in University Place’s older homes is usually caused by moisture from showers or leaks combined with the freeze-thaw cycles of our winters. If the brick is sound but the mortar is crumbling, Medina uses a technique called "repointing," where we remove the damaged mortar, clean the joints, and fill them with a new, flexible mortar mix that matches the original. For bathrooms with tile, we take extra care to avoid disturbing the tile edges. However, if the brick is also deteriorating (look for powdery, discolored bricks), we’ll need to replace the veneer or install a moisture barrier behind the tile to stop further damage. Repointing costs $500–$1,500 for a small bathroom, while full veneer replacement runs $3,000–$7,000. The key is acting fast, once mortar crumbles, it accelerates brick decay. University Place, WA’s climate, with its high humidity and mild winters, makes this a common issue in homes built before the 1980s. More on this in the towns we cover.
5. What’s the difference between a tub/shower liner replacement and a full bathroom remodel in University Place?
A liner replacement focuses only on the tub or shower pan, while a full bathroom remodel includes tile, fixtures, plumbing, and sometimes structural changes. In University Place, where many homes have original 1950s–1970s plumbing, a liner replacement ($800–$2,500) is often a cost-effective fix for localized rot. But if the surrounding tile, grout, or masonry is also failing, a partial remodel ($5,000–$12,000) may be the smarter long-term choice. Medina recommends a full assessment before deciding. For example, if your University Place home’s bathroom has brick walls with efflorescence, cracked grout, and a rotting liner, replacing just the liner will leave the other issues unresolved. We often bundle liner replacements with tile regrouting, mortar repointing, and waterproofing to create a comprehensive solution. For a full remodel, we’ll coordinate with your plumber and electrician to ensure the new layout meets modern codes, especially important in older homes where original wiring or pipes may need upgrades. the EPA's lead-safe renovation rule applies if your home was built before 1978, requiring certified lead-safe practices for renovations.

6. How do you prevent mold behind tile in University Place bathrooms with brick walls?
Mold behind tile in brick-walled bathrooms is a silent problem until it’s too late. The issue stems from two factors: poor waterproofing and the porous nature of brick. Medina’s solution starts with removing the existing tile (if mold is present) and installing a waterproof membrane, like a liquid-applied barrier or a peel-and-stick sheet, before re-tiling. For brick walls, we also apply a moisture-resistant primer and seal the mortar joints with a waterproof grout. Ventilation is critical in University Place’s humid climate, so we recommend installing an exhaust fan with a humidity sensor (not just a timer) and running it for at least 30 minutes after showers. If your bathroom lacks a window, consider adding a small, high-mounted vent or a dehumidifier. For severe cases, we’ve even installed hidden moisture barriers behind the brick veneer to stop water from seeping into the wall cavity. The upfront cost ($1,500–$4,000) prevents costly mold remediation later. the U.S. Environmental Protection Agency estimates that proper ventilation can reduce indoor mold growth by up to 80%.
7. Should you repair or replace your University Place bathroom’s tile if it’s old but structurally sound?
If the tile itself isn’t cracked or loose but the grout, caulk, or surrounding masonry is failing, repair is often the better choice. Medina sees this frequently in University Place homes with original 1970s tile that’s still intact but surrounded by crumbling mortar or peeling caulk. Regrouting, resealing, and repointing the brick can restore the look for a fraction of the cost of a full tile replacement ($3,000–$8,000 vs. $10,000–$20,000). However, if the tile is cracked, cupped, or lifting, replacement is necessary to prevent water damage. For brick walls, we sometimes leave the original tile in place if it’s in good condition and focus on repairing the substrate. The key is assessing the tile’s adhesion, tap each tile with a screwdriver. If it sounds hollow, it’s time to replace. For a partial remodel, we’ll match the existing tile as closely as possible to maintain your home’s character. If you’re considering a full update, now’s the time to explore modern waterproofing options like large-format tile with minimal grout lines, which reduces future maintenance.

Frequently Asked Questions
My University Place bathroom’s brick walls have black stains near the shower, is this mold, and how do you fix it?
Those black stains are almost always mold growing on the grout or mortar, fed by moisture trapped behind the tile. Medina starts by removing the affected grout, cleaning the brick with a bleach solution (1 part bleach to 3 parts water), and then regrouting with a mold-resistant epoxy grout. We also install a waterproof membrane behind the tile and improve ventilation. If the brick itself is stained, we may seal it with a mold-inhibiting primer. Without fixing the moisture source, the mold will return within months. For severe cases, we’ve even replaced the brick veneer with a moisture-resistant material like cement backer board.
Why does my University Place bathroom’s tub liner keep separating from the wall, even after recaulking?
This happens when the liner’s flange isn’t properly sealed to the wall or when the wall itself is shifting. In older University Place homes, the original framing or drywall may have settled, creating gaps. Medina’s fix is to remove the old caulk, clean the flange and wall surface, and apply a bead of 100% silicone caulk in a J-shape. But if the wall is still moving, we’ll install a flexible membrane or a new backer board before recaulking. For brick walls, we also check for efflorescence, if the brick is absorbing moisture, the caulk won’t stick long-term. A temporary fix is to use a waterproof tape under the caulk, but the real solution is addressing the root cause, whether it’s poor installation or structural movement.
Can Medina Bathroom Remodeling help with kitchen remodeling too, or do you only do bathrooms?
We focus on bathrooms but also tackle kitchens in University Place, Tacoma, and Fife. Many clients bundle both jobs to save time and money. For example, if you’re refreshing your South Des Moines master bath, we can sync it with a kitchen remodel, using the same materials, fixtures, and trades for plumbing and electrical. Our crew handles brickwork, tile, and waterproofing in kitchens with wet bars or laundry areas too. We often push for better ventilation and waterproofing in kitchens, especially with Puget Sound’s damp air, just like we do in bathrooms.
How do you handle lead paint or asbestos in older University Place bathroom tile or masonry?
If your University Place home was built before 1978, the tile, grout, or mortar may contain lead, and older insulation or caulk could have asbestos. Medina follows strict EPA guidelines for lead-safe renovations, including containment, HEPA vacuums, and proper disposal. For asbestos, we work with licensed abatement contractors to remove and seal affected materials before proceeding. We’ll always inspect for these materials during your initial consultation and provide a plan to address them safely. The EPA’s lead-safe renovation rule the EPA's lead-safe renovation rule requires certified renovators for work disturbing lead paint, and we’re fully compliant. For asbestos, we coordinate with certified professionals to ensure your family’s safety during the remodel.
