A standard residential deck build typically takes one to two weeks once construction begins. However, the total timeline includes the design phase and the local permitting process, which can add several weeks. At LaMoria Construction, we handle the permits for you to ensure your project stays on schedule and meets all local safety codes.

In Cowlitz County, a professionally installed 12x12 (144 sq. ft.) deck typically costs between $5,500 and $11,500. A basic pressure-treated wood deck usually starts on the lower end, while premium composite decking (like TimberTech) with custom railings often falls in the higher end of that spectrum. These estimates include professional labor, local building permits, and high-quality materials suited for the Pacific Northwest climate. Prices vary based on site slope, railing choices, and current material market rates. Email us to schedule a site visit for a firm quote.

In most cases, a building permit is required for any deck attached to a home or any structure over 30 inches above the ground. Even for "replacement" decks, local codes often require a new inspection to ensure the footings and framing meet current safety standards. We manage the entire permit and inspection process for our clients.

We handle the heavy lifting for you! We provide custom 3D design plans for every project to ensure the layout meets your needs and complies with all local building codes. Once you approve the design, we manage the entire permitting process, from submitting the structural drawings to scheduling the final inspections. You don't have to worry about the paperwork—just the guest list for your first BBQ.

Composite decking is worth the investment for homeowners seeking a low-maintenance, long-lasting outdoor space. Unlike wood, composite materials won’t rot, warp, or splinter and never require staining or sealing. While the upfront cost is higher, the savings on maintenance and the 25-plus year lifespan often make it more cost-effective over time.

Yes. Local zoning codes in Cowlitz County typically require "setbacks," which dictate how close a structure like a deck, pavilion, or gazebo can be to your property line. While a fence can often sit directly on the line, a deck or permanent roofed structure may need to be 5, 10, or even 20 feet away, depending on your specific lot's zoning. At LaMoria Construction, we review your plot plan and local ordinances to ensure your project is positioned legally to avoid costly fines or removal orders. Note: Setback requirements can change if your property is part of an HOA (Homeowners Association). Be sure to check your neighborhood bylaws! Utility easments can also affect setbacks.

Traditional deck screws are driven through the top of the boards, leaving visible screw heads. Hidden fasteners are typically clips installed between the deck boards, or face screws with plugs made from your decking material that fill and conceal the screw hole, creating a completely smooth, fastener-free surface. While hidden fasteners are slightly more expensive, they provide a premium "indoor" look.

The ledger board (where the deck attaches to your house) is the most critical point for preventing rot. We use a multi-stage flashing system that includes a "drip edge" and high-performance waterproof membranes. This ensures that water is diverted away from your home's rim joist and siding. Proper flashing is the difference between a deck that lasts 10 years and one that lasts 30+, and it is a standard part of every LaMoria installation.

The timing for sealing or staining your deck depends entirely on the material used during construction: Pressure-Treated Lumber: This wood is often "wet" from the chemical treatment process. You should typically wait 3 to 6 months before treating it. A good rule of thumb is the "Splash Test": sprinkle some water on the boards; if it beads up, the wood is too wet. If it soaks in, it’s ready for stain. Cedar or Redwood: These natural woods can be treated much sooner—usually within 2 to 4 weeks—once the surface moisture has evaporated. Kiln-Dried Lumber: If you opted for premium kiln-dried wood, it can often be stained immediately after installation. Pro Tip: Waiting too long (over a year) can lead to UV damage and "silvering," while staining too early can cause the product to peel because it can't bond with the damp wood.

Less than traditional wood! Because exotic hardwoods are naturally dense and moisture-resistant, they don't splinter, warp, or rot easily. They require no chemical pressure treatments. Care is simple: keep the surface clean and apply a specialized hardwood oil finish annually if you want to preserve the rich color, or let it naturally weather to a classic silver patina with virtually no ongoing staining required.

Exotic hardwoods (such as Ipe, Cumaru, or Garapa) are naturally dense and highly resistant to rot and insects, making them exceptionally durable. To maintain their rich, natural color, apply a penetrating oil finish specifically formulated for dense hardwoods once a year. If you prefer a low-maintenance, weathered look, you can leave the wood untreated, allowing it to naturally age into a silver-gray patina without losing its structural integrity. Regular maintenance simply involves keeping the surface clear of leaves and debris, followed by an occasional wash with a mild deck cleaner.

Like all natural wood exposed to UV light, exotic hardwoods will fade over time into a silver-gray patina if left untreated. If you want to retain or restore the deep, rich tones of your wood, simply wash the deck with a dedicated hardwood cleaner/brightener and reapply a UV-blocking oil finish. Because hardwoods are so dense, oil sits near the surface rather than soaking deep down, making routine touch-ups quick and straightforward.
