Waterproofing Consulting in Riverside, CA
Most water damage on Riverside buildings does not start where you see the stain. It starts where the flashing was rushed, the deck coating thinned out under years of hard inland sun, or a balcony slope was off by a quarter inch. By the time the stain shows up inside a unit, the framing behind the stucco has been wet for a long time.
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 Riverside and the Inland Empire. 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 Riverside
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 Riverside 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 Riverside multi-family buildings get caught during SB-721 or SB-326 inspections. We perform both. SB-721 inspections cover apartment and multi-family buildings with three or more units, and SB-326 inspections cover 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 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 Riverside
Riverside is an inland climate, and that shapes how buildings fail here. Long, hot, dry stretches bake deck coatings and dry out sealants, then a few hard winter storms and the occasional summer monsoon push water into every weak point at once. The construction details that fail across the Inland Empire are almost always the same.
Deck coatings that have chalked out and cracked from years of intense inland UV.
Stucco walls with no proper kickout flashing at roof-to-wall intersections.
Older wood-framed walkways and stairs where the coating has split at the seams.
Balcony slopes that never drained right, so water sits on the deck instead of running off.
Buildings where the original waterproofing is simply at or past its useful life.
Riverside also has a large stock of older apartment and condo buildings, which means a real share of the multi-family units fall under SB-326 or SB-721. That is the part owners and boards do not usually see until a leak makes it inside a unit.
Waterproofing problems rarely stay cosmetic. When a membrane or a flashing detail fails, it often turns into a code repair. Our guide on how waterproofing failures trigger SB-721 and SB-326 repairs walks through how that happens and how to get ahead of it.
Why Riverside 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 shaded by what someone wants to install on your building next month. If you are weighing whether you need a consultant or a contractor, our note on when to hire a waterproofing consultant explains the difference.
- 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 from one schedule. We inspect across Riverside, Los Angeles, Orange County, San Diego, Santa Clarita, and the Desert Cities. 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 Riverside 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 a Riverside property?
Spring and early summer book up first.
