Waterproofing Inspection & Moisture Detection in Los Angeles

Investigate before selecting a repair
Why the Source of a Leak Can Be Difficult to Locate
Water can travel beneath coatings, along cracks and joints, through framing, or between layers before becoming visible. A stain below a balcony may originate at a railing post, door threshold, drain, wall transition, or crack several feet away.
An inspection begins by comparing the visible symptom with the surrounding waterproofing assembly. We review the substrate, surface wear, previous repairs, penetrations, edges, changes in elevation, drainage, and connections between different materials.
The goal is to identify likely moisture entry points and determine whether a focused repair, further access, maintenance, or broader system replacement is appropriate. This service evaluates waterproofing conditions; specialized structural or statutory inspections should be performed by the qualified professional required for that purpose.
Know the warning signs
When to Request a Waterproofing Inspection
An evaluation is useful before buying materials, repeating a patch, or allowing a moisture problem to continue.
- Water stains, drips, dampness, or peeling finishes below a surface
- Cracked, bubbling, peeling, or separating waterproof coatings
- Soft plywood, loose tile, concrete deterioration, or movement
- Standing water or drainage flowing toward doors and walls
- Moisture near drains, railings, posts, penetrations, or planters
- Musty odors, efflorescence, rust staining, or slow-drying areas
- Recurring leaks after previous patching or surface sealing
- An aging system that has not been evaluated or maintained recently

What We Evaluate During a Waterproofing Inspection
The inspection is focused on conditions that affect waterproofing continuity and moisture movement.
Coating and Membrane Condition
We look for cracks, wear, blistering, separation, punctures, incompatible repairs, and areas with poor adhesion.
Drains and Water Paths
Standing water, slope, drains, scuppers, outlets, and likely pathways toward walls and penetrations are reviewed.
Transitions and Penetrations
Doors, walls, edges, railings, posts, pipes, planters, and changes in material are evaluated as critical details.
Substrate Indicators
Softness, movement, deterioration, cracking, staining, and other signs may indicate moisture affecting concrete or plywood below.
Previous Repairs
Earlier patches and coatings are reviewed for compatibility, continuity, and evidence of recurring failure.
Repair Recommendations
Observed conditions are organized into practical next steps for maintenance, targeted repair, further access, or replacement.

- DiscussWe begin with the location, timing, weather conditions, prior repairs, and visible symptoms reported at the property.
- ObserveThe affected surface and accessible areas below or beside it are reviewed for patterns and moisture indicators.
- TraceLikely water paths are evaluated around cracks, drains, edges, transitions, penetrations, and material changes.
- AssessThe condition of the existing waterproofing and substrate indicators is considered together.
- RecommendWe outline the appropriate next step for maintenance, repair, additional access, or system replacement.

Common questions
Waterproofing Inspection & Moisture Detection FAQs
Can you find a leak if the stain is not directly below it?
Often, the investigation can identify likely entry points by comparing the stain with cracks, transitions, drains, penetrations, and water paths above. Some concealed conditions may require additional access to confirm.
What surfaces can you inspect?
We evaluate waterproofing conditions on concrete and plywood decks, balconies, patios, walkways, tile and paver assemblies, roof decks, planters, retaining walls, and other accessible exterior surfaces.
Do you use moisture-detection tools?
The inspection method depends on the property and accessible conditions. Visual evaluation and appropriate moisture-detection methods may be used to compare affected and surrounding areas.
Will an inspection tell me whether to repair or replace the system?
The observed condition can help determine whether maintenance, a targeted repair, further access, or broader replacement is the practical next step. Concealed damage may only become clear after affected layers are opened.
Is this the same as an SB 721 or SB 326 inspection?
No. This service evaluates waterproofing and moisture conditions. Statutory balcony inspections and structural certifications must be completed by the qualified professional required by the applicable law.
Which areas do you serve?
Our service area includes Santa Monica, Beverly Hills, Malibu, West Hollywood, Marina del Rey, Manhattan Beach, Van Nuys, Woodland Hills, Calabasas, and surrounding Los Angeles communities.
