Harbor-front property on dredged ground and artificial islands. Water is on three sides of most of it.
Newport Harbor is a semi artificial harbor formed by dredging the Newport Bay estuary in the early 1900s, and several artificial islands were built that are now covered with private homes: Balboa Island, Lido Isle, Linda Isle and others. Property here often has water on more than one side, so salt air, humidity and wind driven spray reach surfaces that inland would only ever see rain.
That exposure punishes the details rather than the field of the deck. Fasteners, flashing, railing post penetrations and the joint where a deck meets the building are where failures start, and they are the parts of the job we do not rush.
About 15 percent of the housing sits vacant at any given time, which is what you expect where many properties are second homes. An empty house is where a slow leak runs unnoticed for a whole season and turns into framing damage.
Of 45,016 housing units, roughly 54 percent of occupied ones are owner occupied, so the work runs from private waterfront decks to shared walkways and stairs on rental and condominium buildings. On the water both face the same corrosion problem.
We fabricate the metalwork ourselves, which matters on a harbor property. A guardrail or stair section that has lost thickness at the base does not get plated over. It gets replaced and sealed where it passes through the deck.

Learn more →Newport Beach permits construction to regulate the work and reduce the hazards of unsafe construction. The city does publish a list of work needing no permit, covering finish work such as floor covering and painting, low fences, and platforms, decks and walks 30 inches or less over grade. Elevated deck and balcony waterproofing over living space is not in that category, so we permit it and get it inspected.

Fast, no-obligation local quotes.
Newport Beach exempts platforms, decks and walks 30 inches or less over grade from the permit requirement. Above that, or where the deck sits over living space, it is permitted work and we file it and get it inspected.
Because water is on more than one side. Salt air and spray reach fasteners, flashing and railing penetrations continuously, so the connections give up long before the field of the deck shows anything.
Vacancy runs around 15 percent here, and an empty house is where a leak goes unreported. Have the deck looked at before the wet season rather than after, because the first sign in an unoccupied home is usually rot rather than a stain.
A professionally installed waterproofing system typically lasts many years. Capital Deck & Stair backs most projects with an 8-year warranty on workmanship, and proper maintenance can extend the life well beyond that.
Cost depends on the surface size, condition, and the coating system required. We provide a clear, itemized quote after a free on-site inspection, with no obligation and no pressure.
