Forensic Remodeling
When something is wrong with your bathroom but no one can tell you what — we find it, document it, and fix it right. No guessing. No patching over problems.
What It Is
Finding What Other Contractors Missed
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 starts.
Do You Need This?
Signs You May Need a Forensic Assessment
These are the situations we get called in to investigate most often. If any of these sound familiar, the problem is almost certainly more serious than it looks.
Persistent moisture or musty odor
Even after the surface looks dry, moisture trapped in the substrate keeps feeding mold growth and breaking down the structure behind your walls.
Tiles cracking or popping loose
Tile failure is almost never a tile problem — it's a substrate movement problem caused by improper backer board, missing expansion joints, or a failed mortar bed.
Grout that keeps cracking or discoloring
Recurring grout failure means there's movement in the substrate or an incompatible material combination. Regrouting without fixing the cause just delays the next failure.
Soft or spongy floor near the shower
A soft subfloor next to a shower almost always means the shower pan has been leaking — sometimes for years. The damage usually extends well beyond what you can see.
Water stains on the ceiling below
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.
A remodel that was just done and is already failing
If a recently completed bathroom is already showing problems, the installation was wrong from the start. A forensic assessment will identify every deficiency.
How We Work
The Forensic Process
Initial Assessment
We start 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.
Investigative Demolition
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 photograph everything before anything is disturbed.
Written Findings Report
Before any repair work begins, you get a written report documenting every deficiency found, its likely cause, and what fixing it correctly requires. No surprises.
Correct Rebuild
The rebuild follows the Paragon Standard — full substrate preparation, proper waterproofing, correct materials, and installation to manufacturer specifications. No shortcuts, no patches over problems.
Documentation and Warranty
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 follows the same Paragon Standard as every remodel — because the correct approach doesn't change based on how the project started.
What You Receive
- Written findings report before any work begins
- Photographic documentation of all hidden deficiencies
- Full substrate removal and correct preparation
- Proper waterproofing system installed to spec
- Phase-by-phase photo record of the rebuild
- Written warranty on all completed work
Why It Matters
Patching vs. Fixing
The typical contractor approach
- ×Replace the visible damaged material
- ×Apply new grout or caulk over the problem area
- ×Declare the job complete
- ×Return when it fails again — and charge again
The ParagonCA forensic approach
- ✓Investigate the root cause before touching anything
- ✓Document every deficiency in writing
- ✓Remove all compromised material — not just the surface
- ✓Rebuild correctly so the problem cannot recur
A forensic remodel costs more than a patch. It's also the last time you'll need to spend money on that problem — because it won't come back.
Project Example — Orinda, CA
Three Contractors. Three Failed Repairs. One Root Cause.
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. By the time we were called in, the homeowner had already spent more on the two failed repairs than the forensic remodel cost.
Common Questions
Frequently Asked 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 we proceed.
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 right call. We tell you what we find before any work begins, give you our honest recommendation, and let you make the decision.
Can you work with my insurance company?
Our relationship is with you, not your insurance carrier. We provide thorough photographic documentation and a written findings report that you can use however you see fit — including to support a claim. If your adjuster has technical questions, we're happy to speak with them directly. We don't file claims or negotiate settlements, but we do stand behind our findings and our work.
How long does a forensic remodel take?
The assessment phase typically takes one to two days. The rebuild timeline depends on scope — a standard bathroom remodel done correctly runs six to eight weeks. A forensic remodel takes longer because it may involve mold remediation, structural repairs, and correcting work that was never done right in the first place. We provide a detailed timeline in the written proposal before any work begins, and we don't compress it to win a bid.
Is forensic remodeling more expensive than a standard remodel?
The per-square-foot cost is higher because the scope is more extensive — full substrate removal, investigation, documentation, and correct rebuild. But it's often comparable to or less than the cumulative cost of multiple failed repairs. More importantly, it's the last time you'll need to spend money on that problem.
