The St. Andrews properties we serve tend to share a profile: Close-in lots where fence lines, irrigation heads, and pets shape how we work. Planning pressure washing for that reality—rather than a generic template—is what keeps results consistent from visit to visit.

Seasonal timing for St. Andrews
South Carolina's long growing season means timing matters more than most guides suggest.
- Post-pollen (late April–May): The most popular wash window in St. Andrews. Driveways, siding, and patios covered in yellow film clean up fast.
- Pre-stain/seal: If you’re sealing a deck or concrete, schedule the wash 2–3 days before so surfaces dry completely.
- Fall exterior refresh: Before hosting season, a full wash clears summer mildew and organic buildup.
Choosing the right approach
| Option A | Option B | When to choose |
|---|---|---|
| Pressure Wash | Soft Wash | Pressure washing is for hard surfaces (concrete, brick). Soft washing uses lower pressure with cleaning solution for siding, wood, and painted surfaces. |
| DIY Rental | Professional Service | Rental units can damage siding or etch concrete without experience. Professional service matches PSI to the surface and carries insurance. |
PSI guide: every surface needs different pressure
Using the wrong pressure setting is the fastest way to damage a surface. Here's what we dial in for each material.
| Surface | PSI range | Method | Notes |
|---|---|---|---|
| Concrete driveway | 3,000–3,500 PSI | Surface cleaner attachment, 15° or 25° nozzle | Most forgiving surface. Pre-treat oil stains with degreaser. Even sweeping pattern prevents striping. |
| Wood deck (pressure-treated) | 1,200–1,500 PSI max | 25° fan nozzle, 12+ inches from surface | Too much pressure splinters the grain and forces water into the wood. Always wash with the grain. Let dry 48 hours before staining. |
| Composite deck (Trex, TimberTech) | 1,300 PSI or soft wash only | 40° nozzle or low-pressure soap wash | High pressure voids most composite warranties. Soft wash with oxygen bleach solution is usually enough. |
| Wood fence (cedar, pine) | 1,200–1,500 PSI | 25° nozzle, top-down strokes with the grain | Fence boards are thinner than deck boards — even easier to damage. Start low and test a hidden section first. |
| Vinyl fence / siding | 1,300–1,600 PSI or soft wash | 25° or 40° nozzle, never aim upward under lap joints | Vinyl cleans easily but water driven behind it causes mold in wall cavities. Always spray downward at siding seams. |
| Brick / pavers | 2,000–2,500 PSI | 15° or 25° nozzle, re-sand joints after cleaning | Mortar and polymeric sand wash out if pressure is too high. Plan to re-sand paver joints after the wash. |
| Painted surface | Soft wash only (under 1,000 PSI) | Chemical wash with surfactant, gentle rinse | Pressure lifts loose paint and voids prep work. If the goal is paint removal, that's a different scope and price. |

Mold, mildew, and algae: soft wash vs pressure wash
- St. Andrews's summer humidity regularly exceeds 80%, which is exactly what mold, mildew, and algae need to colonize exterior surfaces. The green-black film on north-facing walls, shaded concrete, and under-deck areas isn't dirt—it's biological growth.
- Soft washing is the correct approach for mold and mildew on siding, stucco, and painted surfaces. It uses a low-pressure spray (under 1,000 PSI) with a sodium hypochlorite or oxygen bleach solution that kills the organism at the root, not just the surface.
- High-pressure washing blasts the visible growth off but leaves the root structure alive in the pores of the material. The mold returns in 3–6 months instead of 12–18 months with a proper soft wash.
- Concrete driveways and sidewalks can handle pressure washing for mold—the surface is hard enough. But even on concrete, a pre-soak with surfactant solution cuts the work in half and gives a cleaner result.
- Vinyl siding, Hardie board, and wood should never get full pressure for mold removal. The water forces spores deeper into the material and can drive moisture behind the siding where it causes hidden mold growth inside wall cavities.
- Best timing: schedule mold/mildew treatment in early summer (June) before the growth peaks, or in early fall (September) after the worst humidity passes. Booking before fall in St. Andrews is smart—everyone calls at once when they notice it, and wait times spike.
Selling your St. Andrews home? Prep the exterior first
Curb appeal drives the first impression online and in person. A clean, maintained exterior costs a fraction of interior staging but influences offer speed and price.
- A clean driveway and walkway are the first things St. Andrews buyers notice in listing photos. Algae-stained concrete signals deferred maintenance.
- Wash the driveway, front walkway, and porch 3–5 days before photos. Concrete needs time to dry evenly for a clean camera result.
- Side-of-house siding wash matters too—buyers walk the perimeter during showings, and green streaks on vinyl raise red flags.
- Bundle the wash with gutter and exterior cleaning to check three curb-appeal boxes in one visit.

FAQ
Pressure Washing in St. Andrews — common questions
- Will your business name match what I see on Google?
- Yes—our site and Google profile use the same legal business name and service-area story. If something looks off after verification, tell us so we can correct mismatches fast.
- Do you publish real project photos?
- We’re replacing stock imagery with real Midlands jobs as assets come in. Case studies document problem → scope → outcome so you can judge how we think—not just marketing photos.
- Will pressure washing damage my St. Andrews home’s siding?
- Not when the method matches the material. We separate concrete work from siding and use softer approaches where high pressure would risk etching or forcing water behind trim.
- Can I read reviews before I book?
- Yes—our reviews page explains how we’ll sync with Google after verification. Honest feedback matters more than a perfect score.
- What if my St. Andrews lot is unusual?
- That’s common—corner lots, long drives, lake slopes, and tight side yards change time-on-site. We quote for the layout you have, not a generic flat rate.
- What’s the difference between pressure washing and soft washing?
- Pressure washing uses high-pressure water for hard surfaces like concrete and brick. Soft washing uses lower pressure with cleaning solutions for vinyl siding, painted wood, and roofing where high pressure would cause damage.
- Does pollen season affect when I should wash my St. Andrews home?
- Yes. Heavy pollen buildup (March–April in the Midlands) coats driveways, siding, and outdoor furniture. Scheduling a wash after peak pollen clears everything at once instead of fighting it mid-season.
