Roof-Covered Patio Addition
A covered patio addition that extends the usable season, built to tie cleanly into the existing roofline and hold up to Pacific Northwest weather.

Olguin C Landscaping is headquartered right here in Beaverton. That means faster estimates, a crew that already knows how the clay-heavy soil around Beaverton drains in a wet February, and a team you can actually run into at a job two streets over from your own.

The Beaverton Standard
We build patios, retaining walls, drainage systems, and full outdoor living spaces for homeowners throughout Beaverton, from hillside lots on Cooper Mountain and Sexton Mountain to established yards in Murrayhill and Central Beaverton. Every project starts the same way: with what's underground, not what's on top of it.
We fixed a patio last year that had sunk after less than two seasons. The gravel base underneath had never been properly compacted. You could push a metal stake bar eighteen inches into the ground by hand. That's the difference between a base that was packed in right and one that was just thrown down and covered up.

5reasons
Most companies talk about design first. We talk about compaction first, because that's the part that decides whether a patio holds up for twenty years or sinks in two.
Every hardscape project in Beaverton starts with a gravel base and real mechanical compaction, packed in right and not thrown down and covered up.
Drainage is planned for your yard's actual elevation, not a guess. In clay-heavy Beaverton soil, that's the difference between a dry patio and a wet one.
We're licensed for backflow testing and hold our own permits in Oregon (LCB #9957) and Washington (GCC #OLGUICL807RZ).
The team that designs your project is the team that builds it, from the base and drainage to the irrigation and lighting. Not a sub we handed it off to.

Design · Construct · Maintain
Our core work covers hardscaping and paver patios, retaining walls, drainage and irrigation systems, outdoor living spaces, and landscape design with a 3D consultation so you can see the space before anything gets built. Design, construct, maintain: that's the whole relationship, not just the install.

Yes. We're licensed for backflow testing in-house and hold our own permits in both Oregon and Washington, so nothing gets subbed out or delayed waiting on someone else's schedule.
Sometimes. Taller retaining walls, and walls holding back a slope, a driveway, or a structure, generally need a permit from the City of Beaverton, and drainage that ties into storm lines falls under Clean Water Services rules. We pull our own permits and check what your property needs during the estimate.
It depends on scope. A patio is a different timeline than a full retaining wall and drainage overhaul. We'll walk you through a realistic timeline during your design consultation.
Yes, we offer a 3D design consultation so you can see the layout before construction starts.
If your yard needs work that actually lasts, from a patio that won't sink in two years to an irrigation system that stops wasting water, the City of Beaverton's local landscaping guidelines are a good starting reference, and we're a good next call.
