Deck Waterproofing in Whittier
Long-lasting waterproof coating systems that keep walking decks, roof decks, and balconies protected from water intrusion.
Deck Waterproofing detailsWhittier has designated historic districts, and work on those properties gets looked at more closely.
Takes about 30 seconds. No obligation, no pressure.
Whittier has neighborhoods the City Council has designated as historic districts, on the Historic Resources Commission's recommendation, comprising most of the Whittier Historic Neighborhood Association area and containing many Craftsman and Spanish Colonial Revival homes. If your property sits inside one, exterior work that changes what is visible gets more scrutiny, and planning for that is easier than reacting to it.
Older housing also means older exterior structures. Decks, porches and stairs on these properties have usually been repaired and recoated several times across their life, and layered coatings that no longer bond to one another are the normal find rather than the exception. Adding another layer over that is money spent on a problem that returns.
The city has 29,734 housing units, 57.9 percent owner occupied and 42.1 percent rented, bordered by Hacienda Heights to the northeast, City of Industry to the north, Pico Rivera to the west, La Habra Heights to the east and Santa Fe Springs to the south.
On period houses the porch and its stairs are usually the problem, not a modern deck. Water gets into the connection at the house, works through the framing under the decking, and rots the joist ends where nobody looks. The surface can pass a glance for years while that happens.
Where a stair run is past honest repair we fabricate replacements, and on a period property the profile, rise and appearance of that run matter as much as its waterproofing. We settle those details before starting.

Commercial Waterproofing details
Our team works directly with Building & Safety departments across every city we serve, managing permits and inspections from initial submittal through final sign-off.
Permit Experts detailsWhittier requires the Building and Safety plan review to be complete, and all processing required by other agencies with jurisdiction to be finished and those approvals or fee receipts forwarded to Building and Safety, before a project is ready for permit issuance. That means parallel approvals need managing rather than chasing one at a time. We handle that and the inspections.
Balcony Works is built by the same team behind Capital Deck & Stair Waterproofing, decades of hands-on work across thousands of LA and OC properties.
Most projects are backed by an 8-year warranty on workmanship.

A local crew looks at the actual deck, and the quote comes back itemized.
Drop the WHNA coverage clause here too: It changes the review. The City Council has designated historic districts, following the Historic Resources Commission's review, so exterior work that alters what is visible gets looked at more closely.
Outside agencies. The project is not ready for permit issuance until Building and Safety plan review is complete and all other agency approvals, or receipts for required fees, have been forwarded to them. We track those in parallel.
Often, but only after opening it. Water usually enters at the connection to the house and rots the joist ends where nobody looks, so the decision comes after inspection rather than from the curb.
