Waterproofing Consulting in Orange County, CA
Most water damage in Orange County buildings does not start where you see the stain. It starts where the flashing was rushed, the deck coating was thinned out, or a balcony slope was off by a quarter inch. By the time it shows up inside a unit, the framing behind the stucco has been wet for years.
That is the problem West Coast Deck Inspections was built to solve. We provide independent waterproofing consulting for apartment owners, HOA boards, and property managers across Orange County. We find the leak, document it, and give you a report your insurer, your city, and your repair team can actually work from.
Waterproofing Services We Offer in Orange County
We focus on the inspection and consulting side of the work, not the repair. That is on purpose. You get findings from someone with no financial interest in selling you a new deck coating.
Forensic Water Intrusion Consulting
We trace active leaks back to the source. That includes balconies, decks, walkways, walls, windows, and roof-to-wall transitions. If water is getting in, we find where, document conditions, and lay out what the repair scope needs to address.
Owner Mark Marsch has 27 years specifically in forensic water consulting and 40 years in construction. He personally walks every project. Learn more on our waterproofing consulting page.
Pre-Repair and Pre-Purchase Consulting
Buying a building or planning a major exterior repair in Orange County is not the time to guess. We inspect first, document what is actually wrong, and help you scope the work before contractors quote it. That keeps repair bids honest and prevents change orders the second a wall comes open.
SB-721 and SB-326 Compliance Inspections
Most waterproofing problems on Orange County multi-family buildings get caught during SB-721 or SB-326 inspections. We perform both:
- SB-721 inspections for apartment and multi-family buildings with three or more units
- SB-326 inspections for HOA and condominium associations
These cover Exterior Elevated Elements (EEE): balconies, decks, walkways, stairways, landings, and anything supported in substantial part by wood. The full inspection menu is on our inspection services page.
Expert Reports for Insurance and Legal Use
Insurers and attorneys need documentation that holds up. Our reports are built to be defensible: written by a forensic water consultant, photographed, and tied to specific code references where it matters.
Why Waterproofing Matters in Orange County
Orange County is not a low-water city. It is a delayed-water city. We get long dry stretches, then a few hard winter storms that dump months of rain in days. Buildings here are designed for the average year, not the wet year, and the construction details that fail are almost always the same:
- Balcony decks where the waterproof membrane has chalked out from years of UV
- Stucco walls with no proper kickout flashing at roof-to-wall intersections
- Older wood-framed walkways and stairs where the coating has cracked at the seams
- Buildings near the coast where marine air corrodes flashing and fasteners faster than inland
- Hillside and canyon properties where retaining walls and below-grade decks trap moisture
Orange County also has a heavy concentration of condo and HOA-governed communities, which means a large share of the multi-family stock falls under SB-326. Many of those buildings are old enough that the original waterproofing is at or past its useful life. That is the part owners and boards do not usually see until a leak makes it inside a unit.
Why Orange County Owners and Boards Choose West Coast Deck Inspections
- Owner-performed inspections. Mark personally handles every West Coast Deck inspection. You are not paying for a junior technician with a checklist.
- 40 years in construction, 27 years in forensic water. The reports are written by someone who has been on the build side and the failure-analysis side of the same details.
- Independent. We do not sell deck coatings or repair labor. The findings are not influenced by what someone wants to install on your building next month.
- Reports built to be accepted. Cities, insurers, and HOA boards in California read a lot of inspection reports. Ours are formatted to be useful, not just compliant.
- Southern California coverage. We inspect across Orange County, Los Angeles, San Diego, Riverside, Santa Clarita, and the Desert Cities from a single schedule. If your portfolio crosses metros, you do not need three different inspectors.

Frequently Asked Questions
What is the difference between a waterproofing consultant and a waterproofing contractor?
A contractor sells and installs waterproofing products. A consultant is independent. We diagnose the problem, document it, and tell you what the repair needs to accomplish. The contractor then bids the work against that scope. It separates the diagnosis from the sales pitch.
Do I need a waterproofing consultant if my building already passed its SB-721 inspection?
Not always. An SB-721 inspection focuses on Exterior Elevated Elements and structural safety. If you have an active leak inside the building, water behind a wall, or stains that keep coming back after repairs, that is forensic work. Different scope, same inspector if you call us.
How long does a waterproofing consultation in Orange County take?
It depends on the size of the building and what you want documented. A single-balcony forensic visit can take an hour or two on-site. A full multi-family building can take a day or more, plus report time. We give you a realistic timeline when we quote.
Will your report hold up for insurance or litigation?
Yes. Our reports are written by a forensic water consultant with 27 years in the field and are documented with photos, moisture readings where applicable, and clear written findings. That said, every claim is different, and your attorney or adjuster should review the scope before we start so we capture what they need.
How fast can you get out to an Orange County property?
Spring and early summer book up first. Property managers across Orange County, Los Angeles, San Diego, Riverside, and Santa Clarita are scheduling SB-721 and SB-326 inspections now, and waterproofing consults are usually paired with those visits.
