Decks Built for Year-Round Use

Custom deck design and construction for homes in the Pacific Northwest

A deck that sags, has loose boards, or shows rotting joists is no longer safe to use, and in the greater Portland area, where rain and humidity are present most of the year, wood decks age faster without proper drainage and ventilation. Peak Exteriors builds custom decks using wood and composite materials that are chosen for how well they perform in Pacific Northwest weather, and the framing is designed to meet current building codes and safety standards so that the deck stays level and secure under heavy use.


The process starts with a site visit to measure the space, discuss how you plan to use the deck, and check the ground conditions where the posts will be installed. The crew builds the structural framing first, using pressure-treated lumber for joists and beams, then installs decking boards with proper spacing for drainage and expansion. Railings, stairs, and trim are added last, and all fasteners are chosen to resist rust and corrosion. Free estimates and financing options are available for new deck construction.

How a new deck adds usable space

When Peak Exteriors builds a deck at your home, the crew digs footings to the required depth, installs posts that are plumb and level, and frames the deck structure using galvanized joist hangers and corrosion-resistant fasteners. Decking boards are laid with consistent spacing to allow water to drain through, and the surface is checked for level as each board is fastened. Stairs are built to code with proper rise and run, and railings are installed at the correct height with secure posts.


After the deck is finished, you will notice the surface stays dry faster after rain, the boards do not flex or bounce when you walk across them, and the space feels like an extension of your living area. Wood and composite options are built for Pacific Northwest weather performance.


Peak Exteriors can build decks that connect to existing patios, wrap around the side of the house, or include built-in seating and planters. The crew coordinates with other exterior projects such as siding, roofing, and outdoor kitchen installations if the work is happening at the same time. The service does not include landscaping, irrigation, or electrical work, but the framing is designed to accommodate future additions if you plan to add lighting or outlets later.

What to ask before building a deck

Homeowners often want to know whether composite or wood decking is better, how long construction takes, and what permits are required before starting a new deck project.

What is the difference between wood and composite decking?
Wood decking costs less upfront and can be stained or painted, but it requires regular sealing and maintenance to prevent rot and splintering. Composite decking costs more initially but resists moisture, fading, and cracking without needing much upkeep, which makes it a good choice for Oregon's wet climate.
How long does it take to build a deck?
Most residential decks in Tualatin are completed in one to two weeks depending on size, design complexity, and site conditions. The crew works through the framing, decking, and railing installation in stages to make sure each part is built correctly.
Why does the framing need to meet building codes?
Building codes set minimum standards for footing depth, joist spacing, railing height, and stair dimensions to make sure the deck is safe and stable under load. Peak Exteriors builds to current code so that the deck passes inspection and performs as expected.
What maintenance does a new deck need?
Wood decks need to be cleaned and sealed every one to two years to prevent water damage and sun fading. Composite decks need occasional washing to remove dirt and debris, but they do not require sealing or staining.
When should I replace my deck instead of repairing it?
If the joists or beams are rotting, if the deck surface is uneven or bouncy, or if the railings are loose and no longer secure, replacement is usually the better option. Peak Exteriors inspects the structure and explains what can and cannot be fixed before you decide.
