When something is wrong with your bathroom but no one can tell you what — we find it, document it, and fix it correctly. No guessing. No patching over problems.
What It Is
Forensic remodeling is the systematic investigation of a bathroom that is failing — or that was built incorrectly — to identify the true root cause of the problem, not just the visible symptom.
Most contractors see a cracked tile and replace the tile. A forensic remodeler asks why the tile cracked — and keeps asking until the answer is found. The cause is almost always behind the wall, under the floor, or in a decision made during the original installation that violated basic waterproofing principles.
ParagonCA developed its forensic methodology after years of being called in to fix work that other contractors had already “repaired” — sometimes multiple times. We documented what we found, built a repeatable investigation process, and wrote it into the Paragon Standard.
“The symptom is never the problem. The problem is always what caused the symptom.”
Every forensic assessment begins with a full visual and physical inspection — before any demolition begins.
Do You Need This?
These are the situations we are called in to investigate most often. If any of these sound familiar, the problem is almost certainly more serious than it appears.
Even after the surface appears dry, moisture trapped in the substrate continues to feed mold growth and degrade the structure beneath.
Tile failure is almost never a tile problem. It is a substrate movement problem — caused by improper backer board, missing expansion joints, or a failed mortar bed.
Recurring grout failure indicates movement in the substrate or an incompatible grout-to-tile combination. Regrouting without addressing the cause is temporary at best.
A soft subfloor adjacent to a shower almost always means the shower pan has been leaking — potentially for years. The damage extends well beyond what is visible.
A stain on the ceiling below a bathroom is a sign of active or past water intrusion. The source is rarely directly above the stain — water travels.
If a recently completed bathroom is already showing problems, the installation was incorrect from the start. A forensic assessment will identify every deficiency.
How We Work
We begin with a thorough visual and physical inspection of the entire bathroom — not just the area of visible concern. We probe, tap, and measure. We look at what was done and compare it against what should have been done.
When the surface inspection points to a subsurface problem, we open the wall or floor in a controlled, targeted way to expose the substrate. We document everything we find with photographs before anything is disturbed.
Before any repair work begins, you receive a written report documenting every deficiency found, its likely cause, and the correct remediation. You know exactly what is wrong and exactly what fixing it requires.
Remediation follows the Paragon Standard — full substrate preparation, proper waterproofing system, correct materials, and installation to manufacturer specifications. No shortcuts, no patches over problems.
The completed project is photographed at every phase. You receive a full documentation package showing what was found, what was done, and what is now behind your walls — plus a written warranty on the work.
The rebuild phase follows the same Paragon Standard as every premium remodel — because the correct approach does not change based on how the project started.

Why It Matters
The typical contractor approach
The ParagonCA forensic approach
The cost of a forensic remodel is higher than a patch. It is also the last time you will need to spend money on that problem — because it will not come back.
Project Example — Orinda, CA
A homeowner in Orinda had experienced recurring tile failure in their master shower for four years. Two previous contractors had retiled the shower — once partially, once fully. Both times, the tiles began cracking within eighteen months.
Our forensic assessment found that the original shower pan had been installed without a proper liner, and the mortar bed beneath it had been saturated with water for years. The subfloor framing had begun to deteriorate. Neither previous contractor had opened the floor — both had tiled directly over a structurally compromised base.
The correct repair required full demolition to the framing, subfloor sister-joists, a new shower pan liner, a new mortar bed, and a complete tile installation. The homeowner had spent more on the two failed repairs than the forensic remodel cost.
Common Questions
How do I know if I need forensic remodeling vs. a standard remodel?
If your bathroom has a recurring problem that has already been repaired at least once, or if you have visible signs of moisture damage (soft floors, musty smell, staining), you likely need a forensic assessment first. A standard remodel assumes the existing substrate is sound — forensic remodeling verifies that assumption before proceeding.
Will you tear out my entire bathroom?
Not necessarily. We use targeted investigative demolition — we open only what we need to open to find the source of the problem. In some cases, the damage is localized and the rebuild is limited in scope. In others, the damage has spread and a full rebuild is the correct approach. We tell you what we find before any work begins. From there, we present our professional recommendation — the approach we believe represents the best long-term outcome for your home — along with any viable alternatives where they exist. Ultimately, the decision is yours. Our role is to give you the clearest, most honest picture possible so you can make the choice that is right for you.
Can you work with my insurance company?
Our contractual relationship is with you — the homeowner — not with your insurance carrier. We perform the work on your behalf, and payment for that work is your responsibility regardless of the outcome of any insurance claim. What we do provide is thorough photographic documentation and a written findings report detailing the cause, extent, and required remediation of the damage. That documentation is yours to use however you see fit, including to support a claim with your carrier. If your adjuster has technical questions about our findings, we are happy to speak with them directly and answer those questions honestly. We represent your interests, not the insurance company's — our professional and fiduciary responsibility is to you. We do not file claims, negotiate settlements, or structure our work around insurance timelines. We do the work correctly, document what we find, and stand behind both.
How long does a forensic remodel take?
The assessment phase typically takes one to two days. The rebuild timeline depends heavily on the scope and size of the project. A standard cosmetic bathroom remodel — one where the underlying structure is sound — typically runs six to eight weeks when done correctly. That timeline accounts for dust control, demolition, waterproofing, rough plumbing and electrical, tile and flooring, cabinet installation, trim carpentry, plumbing fixtures, countertop fabrication and installation, glass shower doors, paint, and all the mandatory curing and setting times in between: mortar beds, waterproofing membranes, grout, countertop fabrication lead times, and required waterproofing and plumbing testing before anything is closed up. Any contractor promising a full bathroom remodel in under six weeks is almost certainly skipping steps — compressing curing times, bypassing testing, or cutting corners that will not be visible until the problems resurface. A forensic remodel takes considerably longer. In addition to everything above, it may involve mold remediation, structural repairs, concrete breaking and replacement, and the correction of work that was never done correctly in the first place. Plan to be out of the bathroom for a minimum of eight weeks, and potentially longer depending on what the investigation uncovers. We provide a detailed timeline in the written proposal before any work begins — and we do not compress that timeline to win a bid.
Is forensic remodeling more expensive than a standard remodel?
The per-square-foot cost is higher because the scope of work is more extensive — full substrate removal, investigation, documentation, and correct rebuild. However, the total cost is often comparable to or less than the cumulative cost of multiple failed repairs. More importantly, it is the last time you will need to spend money on that problem.
