Our Professional caulking repair service is the complete removal of failing silicone caulk from shower corners, floor-to-wall transitions, tub surrounds, and fixture joints, followed by replacement with a permanent epoxy-based caulking solution. Epoxy-based caulking does not crack, shrink, or separate under the moisture and thermal movement conditions that cause standard silicone caulk to fail.
Caulk is the first line of defense between your tile surfaces and the structural elements behind them. Every corner seam, floor-to-wall transition, and fixture joint in your shower or tub surround is sealed with caulk because these are movement joints. They expand and contract with every temperature change, every shower cycle, and every minor structural shift in your home. Grout cannot handle this movement. Caulk is the correct material for these joints.
The problem is that standard silicone caulk is not built to last in these conditions long term. It dries, shrinks, and loses its bond. It cracks under thermal stress. Mold establishes itself in and behind the caulk body within months. And once silicone caulk begins to fail, the solution most companies offer is the same product that already failed, applied again. This is why so many homeowners find themselves dealing with the same peeling, cracking caulk year after year.
We do not re-caulk with silicone. We replace it with an epoxy-based caulking solution that bonds permanently to all tile and substrate surfaces and does not share the structural limitations of silicone. One repair. Permanent result. That is the standard we hold ourselves to on every job.
Standard silicone caulk fails in showers and tub surrounds because it faces 3 simultaneous stressors it is not built to withstand long term: continuous moisture exposure, daily thermal expansion and contraction across movement joints, and mold growth within the caulk body itself. Most silicone caulk in active shower environments begins to crack and separate within 2 to 5 years.
Every inside corner in a tiled shower is a change-of-plane joint. Two tile surfaces meeting at an angle expand and contract in different directions with every shower cycle. The water temperature in a residential shower typically runs between 100 and 110 degrees Fahrenheit. The tile and substrate cool completely between uses. This expansion and contraction cycle repeats once or more every day, placing continuous stress on the caulk joint at every corner and transition seam.
Silicone caulk handles this movement reasonably well initially. Over time, however, it dries out and loses elasticity. As it stiffens, thermal movement begins to pull it away from the tile surface at the bond line rather than stretching it. The separation that results is invisible at first. Water enters the gap and has nowhere to go. It accumulates behind the tile, in the substrate, and in the structural framing behind the wall.
At the same time, soap residue, body oils, and shampoo deposits coat the caulk surface with each shower use. These organic compounds become a food source for mold. By the time black mold is visible on the surface of failing caulk, it has already been growing inside and behind the caulk joint for weeks or months. Surface cleaning removes the visible discoloration temporarily. The mold colony behind the caulk is not addressed.
Re-applying silicone over a previously silicone-sealed joint compounds these problems. New silicone bonds poorly to surfaces that have residual silicone contamination. The new application fails faster than the original because the bond starts compromised. This is the cycle that standard caulking services repeat. We end it.
There are 6 key signs that your caulking has failed or is failing. When we see any of these during an inspection, we know exactly what needs to happen.
Caulk that is visibly cracked or split Cracked caulk has lost its structural integrity as a joint seal. Every crack is an open channel through which water travels behind the tile with every shower. A small crack in a floor-to-wall transition caulk line can deliver a consistent stream of water to the substrate and framing behind your shower wall for months before any visible damage appears on the surface.
Caulk that is pulling away from the tile or tub When caulk shrinks and separates from the surfaces it was bonded to, the gap it leaves is wider and more exposed than a simple crack. Separation at the base of a shower wall or along the perimeter of a tub surround is one of the most common starting points for water damage behind tile in residential homes. We see it regularly, and we treat it as the structural issue it is.
Black or dark discoloration along caulk lines Dark discoloration on caulk lines is mold growth, not surface staining. By the time mold is visible on the caulk surface, it has already penetrated the caulk body and is growing behind it as well. Cleaning the surface removes visible discoloration temporarily but does not address the mold colony established within and behind the caulk joint. We remove the caulk, address the joint, and replace it with an epoxy-based solution that does not support mold growth.
Caulk that has been applied over old caulk Layered caulk is one of the most common results of repeated re-caulking with standard silicone. Each new layer bonds to the previous one rather than to the tile surface, producing a joint that is thicker, bulkier, and far more likely to pull away from the tile than a properly installed single layer. We remove all existing caulk layers completely before any new material is applied. There are no shortcuts on our jobs.
Caulk that peels or crumbles when touched Caulk that crumbles or peels away easily has fully lost its bond and its structural integrity. This is a late-stage failure indicator. Joints in this condition have been allowing water infiltration for an extended period and should be repaired without delay.
Caulk that is yellowed or visually inconsistent in color Yellowed caulk has been degraded by UV exposure, chemical exposure from cleaning products, or age. Visually inconsistent caulk across a shower surface is typically the result of multiple rounds of partial re-caulking at different points in time. Our epoxy-based caulking solution is available in 40+ colors matched to your grout lines, producing a visually seamless and consistent finish across every joint we repair.

Our Process
Our caulking repair process uses 3 steps: full removal of all existing caulk, preparation of every joint surface, and precision application of our epoxy-based caulking solution. We work methodically across every corner, transition, and fixture joint in the treated area before we consider a job complete

We remove every trace of existing caulk from every joint we are repairing. This includes all layers of previously applied caulk, all residual silicone contamination on the tile and substrate surfaces, and all mold-affected material from within the joint. Complete removal is not optional. New material applied over residual silicone or over mold-affected joint surfaces bonds poorly and fails faster than the original installation. We do not take shortcuts here because the results of incomplete removal are visible within months.
Once all existing caulk has been fully removed, we prepare every joint surface for the new application. This means ensuring the joint is clean, structurally sound, and completely dry before any new material is applied. We inspect the substrate condition within each joint during this step. Joints that show evidence of water infiltration or structural compromise are identified and discussed with you before we proceed. We tell you exactly what we find.
We apply our epoxy-based caulking solution to every prepared joint using precision application tools. The epoxy compound bonds permanently to all tile and substrate surfaces, remains flexible through the full range of thermal movement that shower environments produce daily, and creates a non-porous, waterproof, mold-resistant seal at every corner and transition. We color match the epoxy to your existing grout lines for a visually seamless finish. Every bead is applied with clean, straight lines and tooled to a consistent profile across the full joint. We do not leave a job until every joint looks exactly as it should.
Our epoxy-based caulking solution and standard silicone caulk are fundamentally different materials with fundamentally different outcomes. Silicone caulk in an active shower environment lasts 2 to 5 years before cracking and separating. Our epoxy-based solution bonds permanently and does not share the structural limitations that cause silicone to fail.

Most caulking services remove your failing silicone and apply the same silicone product that already failed.
They charge you for this service every few years as the cycle repeats. We replace it once with a material that does not share these limitations.
The price of a single epoxy caulking repair from us is comparable to 2 rounds of standard re-caulking from a competitor. The outcome is not comparable at all.

Where We Repair Caulking
Caulking fails at specific locations in every shower and tub surround because these are the joints that bear the highest movement stress and moisture exposure. We repair caulking at 5 primary joint locations and we treat every one of them with the same precision.
Every inside corner in a tiled shower is a change-of-plane movement joint. Two tile planes meeting at a corner expand and contract in different directions with every thermal cycle. Standard silicone applied to these corners dries, stiffens, and loses its bond as the movement it needs to accommodate exceeds what it can flex through. We replace corner caulk with our epoxy-based solution that holds its bond and flexibility permanently across all thermal movement conditions.
The joint where your shower floor meets the wall is the highest-stress caulk location in any shower. It bears the weight of foot traffic, the direct impact of water from the showerhead, and the movement of the shower floor under load. Standard caulk at floor-to-wall transitions typically fails faster than corner seams. We apply epoxy-based caulking to every floor-to-wall transition with particular attention to complete coverage and consistent depth across the full joint length.
The perimeter joint where a bathtub meets the surrounding tile wall is a critical waterproofing joint that combines movement stress from the tub's weight with constant water exposure. Standard caulk along tub perimeters is one of the most common sources of water infiltration behind bathroom walls in residential homes. We replace all tub perimeter caulk with our epoxy-based solution and inspect the full perimeter joint for evidence of prior water intrusion before applying any new material.
The joints around showerheads, body sprays, controls, and soap dish fixtures are exposed to direct water contact and repeated tightening and adjustment over time. These joints are small but structurally important. We repair caulking around all fixtures as part of our standard caulking repair service and match the epoxy color to the surrounding grout for a clean, consistent finish.
Built-in shower benches and recessed niches have multiple change-of-plane joints at every edge and corner. These joints accumulate standing water and soap residue at a higher rate than wall tile joints and deteriorate correspondingly faster. We repair all bench and niche caulking joints with the same epoxy-based solution we use throughout the rest of the shower.

We differ from standard re-caulking services in 3 important ways that determine whether your repair lasts permanently or needs to be repeated in 2 years.
Every standard re-caulking service in our market uses silicone or a silicone-hybrid product. These are the same materials that failed in the first place. The limitations that caused the original failure — drying out, losing elasticity, supporting mold growth, bonding poorly to previously silicone-sealed surfaces — are not addressed by applying the same material again. We use an epoxy-based caulking solution that does not share these limitations. This is the most significant difference between our work and what most other companies offer.
Many re-caulking services apply new caulk directly over old caulk, either partially or completely. This practice produces a thicker, bulkier joint that bonds to the previous caulk layer rather than to the tile surface. The result fails faster than a proper installation. We remove every trace of existing caulk and all residual silicone contamination before applying our epoxy-based solution. New material bonds directly to the tile and substrate surface, not to what was already there.
Standard silicone caulk is available in a limited range of colors that rarely match grout precisely. Most re-caulking jobs leave joints that are visually distinct from the surrounding tile and grout, making repairs obvious and inconsistent. Our epoxy-based caulking solution is available in 40+ colors. We match every joint to your existing grout color so the finished repair is visually seamless across the full surface.

FAQs
Recurring caulk failure is the result of 2 factors. First, standard silicone caulk is not built to withstand the thermal movement, moisture exposure, and mold growth conditions present in an active shower long term. Second, re-applying silicone over a previously silicone-sealed joint produces poor adhesion and accelerated failure. We end this cycle by replacing silicone with an epoxy-based caulking solution that bonds permanently and does not share these structural limitations.
No. Epoxy-based caulking does not bond correctly over residual silicone contamination. We remove all existing caulk and all residual silicone from every joint surface before applying our epoxy-based solution. Complete removal is what makes a permanent bond possible.
Yes. Our epoxy-based caulking solution requires a 48-hour cure period before the repaired joints are exposed to water. We provide full written aftercare instructions before we leave every job so you know exactly when your shower or tub is ready to use.
Yes. We repair caulking in shower corners, floor-to-wall transitions, tub surround perimeters, fixture surrounds, and bench and niche joints. Any tiled wet area with failing caulk is within our scope of work.
The most common indicators of water damage behind tile are hollow-sounding tile when tapped, grout that is cracking or falling out near the affected joints, visible staining on adjacent walls or ceilings, and soft or spongy tile surfaces. We inspect every joint and surrounding tile surface during our free on-site estimate and tell you honestly what we find before any work begins.
DIY caulk application is possible but produces results that fail faster than professional work in most cases for 2 reasons. First, complete removal of existing silicone caulk is time-consuming and difficult without professional tools, and incomplete removal causes the new application to fail prematurely. Second, consumer-grade silicone caulk products do not perform at the level of our epoxy-based solution. Professional caulking repair with the right materials produces results that do not need to be repeated.
Most residential caulking repair jobs range from $150 to $400 depending on the number of joints being repaired, the total linear footage of caulk being replaced, and the scope of the affected area. We provide a free, no-obligation on-site estimate before any work begins with a transparent itemized quote and no pressure.
