Post Construction Cleanup Portland, OR

New siding and exterior trim often pick up construction dust, dirt transfer from adjacent trades, and early-stage organic staining before anyone even signs off on the final inspection. We clean Hardie board, cedar siding, stucco, vinyl, brick, and metal exteriors using a soft-washing approach that protects the finish rather than blasting it.

The process starts with applying a 100% biodegradable detergent to the siding and the exterior of the gutters. We let that dwell for about one minute, then gently rinse everything without high pressure. That combination kills and removes algae, mold, and moss growth while leaving paint, trim, fixtures, and finish quality untouched. For builders and property owners, this means newly finished exteriors get cleaned carefully, with attention to every detail that matters at handoff.

Flatwork and hard surfaces take the most abuse during construction. Concrete, pavers, asphalt, stone, retaining walls, patios, and similar hardscape end up covered in tracked mud, mortar dust, paint splatter, and organic growth that had months to settle in while the project was underway.

We start with a pre-treatment targeting algae, mold, and moss, then move to pressure washing. A surface cleaner is used on flatwork when appropriate to achieve even, streak-free results, and the area is then rinsed clean. Leftover debris is collected and hauled off-site so the property looks ready for presentation, not just washed. Oil stain treatment is available at an additional cost using a heavy-duty degreaser, though results for deep or old oil stains cannot be guaranteed.

Glass clarity and clean detail work are often what separate a property that looks “finished” from one that still looks like a job site. 4 Seasons Softwash cleans both interior and exterior windows, and the team also handles screens and tracks. Screen and track cleaning may carry a small additional charge depending on the scope.

We use DI systems, water-fed poles, squeegees, and mops, with purified water where appropriate. The process includes inspecting the windows, cleaning every surface, reinstalling screens, doing a walkthrough with the customer, and taking after photos to document the results. If broken seals are spotted during cleaning, we’ll point them out, though we can’t guarantee seal diagnosis before the cleaning starts. This section of the cleanup covers the final exterior window presentation and ensuring every pane is clear and clean for move-in or turnover.

Outdoor living surfaces often need attention after construction, landscaping upgrades, or exterior renovation work. We clean composite, cedar, and Brazilian hardwood decks, as well as patio and paver areas. Detergent is applied first, scrubbing is added if needed, and then the surface is lightly washed to remove buildup without damaging the material.

For wood restoration, the company can first clean the deck, apply a wood brightener to rebalance the pH, and, if needed, sand, stain, or seal the surface. For pavers, we pressure-wash the area first and let it dry before offering resanding (poly-sanding or traditional paver sanding). Once dry, two coats of sealer can be applied when sealing is part of the job. On this page, the emphasis is on cleanup and presentation, but restoration and sealing are available as related add-ons for properties that need more.

Gutters collect debris during roofing work, tree clearing, and exterior projects of all kinds. By the time a build or remodel wraps up, most gutters need to be cleared and flushed. 4 Seasons Softwash handles this using either pressure-based flushing methods or manual removal, depending on the job and the sensitivity of the surrounding area.

For properties where blowing debris would create a mess on freshly cleaned siding, the team hand-scoops instead. Before-and-after photos are taken so the customer can see that gutters and downspouts are fully cleared. All debris is cleaned up afterward. Exterior gutter brightening is also available to restore the gutter face’s appearance. Minor above-ground repairs, such as patching or alignment, may be available, along with downspout clearing. The goal is to ensure the entire exterior of the property looks complete at handoff.
