What We Do

Our Services

A quick look at the deck and waterproofing work we handle most.

Deck Installation

A new deck built on proper footings, not just bolted to whatever's there.

Deck Repair

Soft boards, loose railings, and sinking posts, fixed before someone gets hurt.

Deck Staining and Sealing

Fresh stain and sealer to stop sun and rain from cracking your boards.

Deck Waterproofing

Keeps water out of the room under your deck, not just off the surface.

Composite Deck Installation

Low-maintenance decking that won't need sanding and restaining every few years.

Deck Railing Repair

Wobbly rails tightened or rebuilt to code before someone leans on them.

Who We Are

Local deck builders who also handle the waterproofing

We design and build decks for homeowners in Costa Mesa and the surrounding area, and we waterproof the ones that sit over a patio, garage, or living space below. Most people call us because a deck is sagging, a railing has gone loose, or water is finding its way into the room underneath. Salt air off the coast corrodes fasteners faster than people expect, and UV breaks down sealants and coatings years before the structure underneath actually fails. If you're looking at soft boards, rust streaks, or a stain coming through your ceiling below a deck, this is the right page.

We bolt ledger boards to the rim joist with lag or through-bolts, not nails, and flash that connection so water can't track behind the siding. On decks that sit above a garage or patio, we run a waterproof membrane under the walking surface, lapped and sealed at every penetration, because a deck that leaks at one post sleeve will leak there for the next ten years. We use stainless or hot-dipped galvanized hardware near the coast, since standard coated fasteners rust out in a few seasons here. We'll tell you upfront if framing needs to come out instead of being patched over, since covering rot with new boards only hides the problem for a while.

What people said afterwards

5.0 from 100+ reviews
Had two joists going soft near the ledger at our place in Costa Mesa. They caught it before it got worse and the new boards actually match the old ones.

Deck Repair · Long Beach, CA
Water was coming through our balcony into the garage ceiling. Took longer than planned because they found more rot once they opened it up, but it's dry now.
Elaine R.
Raised Deck and Balcony Waterproofing · Anaheim, CA
Went composite after getting tired of staining every summer out in Tustin. Install took about a week, and the railing spacing looks even all the way across.

Common Questions

Questions we get a lot

Questions people usually ask before booking a deck project.

How much does a new deck cost?
A new deck typically runs between $35 and $75 per square foot depending on decking material, railing style, and how much framing and footing work is involved. Composite decking and custom features like built-in seating or multiple levels push the price toward the higher end of that range.
Are you licensed and insured?
Deck building and waterproofing work in California requires a contractor's license, which includes general liability insurance coverage. Proof of license and insurance is available before any work starts.
How soon can you start my project?
Scheduling depends on the season and the size of the job, but a typical deck project can usually be booked within two to four weeks of an accepted quote. Smaller repair jobs often get fit in sooner than full installations.
What areas do you serve?
Deck building and waterproofing work covers Costa Mesa and surrounding Orange County cities including Newport Beach, Irvine, Santa Ana, and Huntington Beach. Travel distance beyond that range can be discussed case by case.
Do you work on condos and townhomes, or just single-family homes?
Deck and balcony waterproofing work is done on single-family homes, condos, and townhomes alike. HOA-attached properties often have their own approval process for exterior work, which can factor into the project timeline.
Will you take on a small repair job, or only full deck builds?
Small repairs, such as replacing a few rotted boards or tightening a loose railing, are handled alongside full deck installations. No job is too minor to quote.
How do I get started?
The first step is a call or message describing the project, followed by a site visit to measure the space and look at any existing structure. A written quote follows that visit, usually within a few days.
What affects the cost of a deck project the most?
Decking material is usually the biggest cost driver, with composite running significantly higher than pressure-treated pine and cedar landing in between. Framing complexity, the number of levels, stairs, and whether waterproofing is involved also move the number.
Do you require a deposit?
A deposit is standard before materials are ordered, with the remaining balance split across project milestones or paid on completion depending on job size. The exact payment schedule is spelled out in the written quote.
What happens if it rains during construction?
Framing and structural work can often continue in light rain, but decking installation, staining, and waterproofing membrane work stop until conditions are dry. Weather delays get communicated as soon as they're known, not after the fact.
