Raleigh’s tree-lined streets are part of its charm, but that deep shade also invites mildew and a thin film of grime on north- and east-facing walls. When siding looks dull, windows spot easily, and walkways feel slick, it’s time for a surface-specific plan that restores color and traction without risking paint, mortar, or landscaping.
Start with a quick exterior audit
Walk the perimeter and note the heaviest growth: under eaves, near downspouts, and along the side yard that stays damp. Check for oxidation (a chalky feel on sunny walls), “tiger stripes” on gutter faces, and dirt bands at deck rails. On hardscapes, flag slippery algae near hose bibs and leaf tannin shadows under trees. A few photos help verify results later and keep any HOA communication simple.
Siding: chemistry first, then a careful rinse
Vinyl and painted fiber-cement respond best to a calibrated soft approach. Pre-wet beds so leaves don’t dehydrate, apply the appropriate detergent ratio to break down organics, allow a short dwell, and rinse with a wide fan tip from top to bottom. Keep a consistent stand-off to avoid lines and reduce dwell near windows and trim so caulk and paint stay happy. On older masonry, test a small section to confirm dwell time and rinse distance before scaling up.
Oxidation and gutter brightening
If fingertips pick up chalk, you’re dealing with oxidation—not something brute force can fix. Use an oxidation-safe cleaner with gentle agitation, then rinse evenly so color reads uniform in daylight. For gutters, those vertical “tiger stripes” are bonded grime; a targeted product and soft pad will restore the bright edge that frames the refreshed siding.
Walkways and entries: uniform beats “wand art”
Footpaths and stoops take daily abuse from foot traffic and blown-in debris. Pre-treat oil, rust, and algae so chemistry does the heavy lifting. Then use a surface cleaner for overlapping passes that dry to an even tone—no stripes, no swirls. Along steps and borders, swap to a controlled wand with a wide fan, holding steady distance to keep edges crisp without cutting into joints.
Windows, fixtures, and details sell the clean
Pre-wet glass and light fixtures before application, shorten dwell nearby, and finish with a top-down rinse. A quick towel on sills and lanterns prevents mineral spotting. Don’t forget mailbox posts, porch ceilings, and the bottom fence rail—small touch-ups there make the whole elevation read “newly detailed.”
Water direction and plant protection
Guide rinse water from house to street so it doesn’t backflow into mulch or track across the entry. Diversion pads and curb socks keep dirty water out of beds. Keep solutions off unsealed wood, door thresholds, and aging outlets. Where appropriate, follow with a neutralizing rinse on delicate shrubs so everything looks untouched after the job.
Timing for best results
Spring clears winter film before pollen spikes; fall resets surfaces ahead of cooler, wetter weeks. Aim for mild wind so application lands only where intended, and allow shade-damp walls time to drip-dry before sunset for a spotless finish.
What a professional visit includes
Expect a written scope, plant-safe chemistries, surface cleaners for uniformity, careful threshold work, and tidy water management. The walkthrough should confirm even color on siding, brighter gutter faces, safer traction on walks, and clean glass and fixtures.
