A pergola is a shade structure, and whether it delivers shade comes down to geometry that most people never get told about. Slat direction, slat depth, and spacing determine what time of day the structure actually blocks sun, and a pergola built without that calculation ends up as an attractive frame that shades the ground at eleven in the morning and does nothing at four in the afternoon when the deck is uncomfortable. In this area that distinction is the whole point of the structure. Pasco afternoons in summer are hot and the sun sits low and to the west late in the day, which is exactly when people want to be outside. Slats running the wrong direction relative to that path will not stop it. We work out which orientation shades the hours you actually use the space, and if the geometry cannot deliver what you want, a louvered top or a partial solid section may be the honest answer instead. Attached and freestanding both work. Attached ties into the house and shades a deck or a back door directly, but it needs the same ledger care a deck does. Freestanding stands on its own footings and can go where the shade is wanted rather than where the wall happens to be. Wind matters for both, since an open structure in an exposed yard takes real lateral load.
We start by asking which hours you want shaded, then design the slat orientation and spacing to that rather than to a standard pattern. Footings, posts, beams, then slats is the build order, and an attached pergola gets the same flashing detail at the wall connection that a deck ledger does. You get the orientation reasoning, a realistic description of the shade it will cast at different times of day, and the footing and wind detail before the build. Where a pergola sits over an existing deck, we check that the deck framing can carry the added load.

Ten services, from a full pool deck build down to a railing swap or a season of stain. Every one of them starts the same way: we look at what the structure sits on, how high it stands above grade, and what the sun does to that side of the house through a Tri-Cities summer.

We work Pasco first and five surrounding communities after it. Two of them are unincorporated, which means county permits rather than a city building department, and one runs a municipal electric utility instead of a PUD. Those differences change the sequence, so we sort them out before scheduling.
Frequently Asked Questions
Deck Contractor can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
There is no single price for a Pasco deck. Cost follows the square footage, the height above grade, whether the framing underneath can be reused, the decking material, and whether the railing is wood, cable, or aluminum. A ground-level platform in an existing footprint and an elevated deck with new footings are not comparable jobs. We price after a walkthrough and measurements, not over the phone.
It depends on two numbers. Pasco Municipal Code exempts decks under 200 sq ft that also sit under 30 inches above the ground, so a small ground-level platform can go in without a permit. Cross either threshold and you need one from the City of Pasco Building Division, where residential permits run a five to seven business day review. We confirm which side of that line your project falls on before quoting it.
For a Pasco summer, the honest answer is that surface color matters more than material category. Lighter boards run cooler underfoot than dark ones, in composite and in wood alike. Composite avoids the annual splintering and checking that dry heat causes in softwood, while a good hardwood or cedar stays cooler than most dark composites. We match the material to how the deck is oriented and how often it is used barefoot.
Ask three things. Whether they build decks specifically or take them alongside fencing and general contracting, whether they will tell you the permit threshold before quoting, and whether their past work is in your climate rather than on the wet side of the state. A crew that cannot answer the permit question in the first conversation has not looked at your project yet.
Schedule follows the permit review, the footing and framing inspections, whether concrete has to cure before framing starts, and lead times on decking and railing. A railing replacement on sound framing and a new elevated deck that needs fresh footings sit at opposite ends of that range. We give you the sequence in writing so you can see which steps are ours and which belong to the city.
Wood is cheaper up front and needs a finish schedule. Composite costs more at install and skips the stripping and staining. In this climate the gap widens, because dry heat and hard sun push a softwood deck toward recoating more often than the same deck would need on the coast. The right choice depends on whether you would rather spend the money once or spread it across seasons of maintenance.
Only if the slats are oriented and spaced for the sun angle you care about. A pergola designed without that calculation shades the ground at midday and stops working in the late afternoon, which is when it matters most here. We design the slat direction around the hours you want to use the space.
Attached shades a deck or doorway directly and uses the house for support, but the wall connection needs proper flashing exactly like a deck ledger. Freestanding goes wherever the shade is actually wanted and avoids touching the house at all. The right answer usually follows where the afternoon sun lands rather than where the wall is.
Often, but the deck framing has to carry the extra load and the posts need to land where the structure can take them. We check the framing and the post locations before agreeing to it, since a pergola adds both weight and wind load to a deck that was not designed for either.
It depends on size and construction, and the City of Pasco publishes a combined checklist covering patio covers, decks, carports, and pergolas. We confirm the requirement for your specific structure at the walkthrough rather than assuming it matches the deck thresholds.
