How to Choose a Pressure Washing Company in Lexington, SC
The wrong pressure washing company can etch your concrete, force water behind your siding, or strip paint off your trim. Here's what to check before you hire — for us or anyone else — and how to tell soft-wash-appropriate surfaces from ones that need real PSI.
"Best" Means the Company That Matches Method to Surface
There's no certifying body that ranks pressure washing companies in Lexington, SC, so "who's the best" really means: who correctly matches cleaning method to surface, carries insurance, and won't damage your property to save time. Pressure washing is one of the easier home services to get wrong in a way that isn't obvious until later — etched concrete, stripped paint, or water forced behind siding doesn't always show up the same day. This guide covers what actually separates a company worth hiring from one that just owns a pressure washer.
Surface-Appropriate PSI Is the First Thing to Ask About
Different surfaces need different pressure, and a company that runs everything at one setting is a red flag. Concrete driveways and walkways can generally handle 3,000–4,000 PSI with the right nozzle and a surface cleaner attachment. Wood decks need much less — typically 500–1,200 PSI depending on the wood's condition, because high pressure will gouge and splinter softer wood fibers. Vinyl siding, brick, and pavers fall somewhere in between and depend heavily on the nozzle angle and standoff distance, not just the PSI number. Ask directly: "What PSI will you use on my driveway versus my siding?" If the answer is the same number for both, that's a problem.
Soft Wash vs. Pressure Washing — Know Which One Your Job Needs
Soft washing uses low pressure (typically under 500 PSI) combined with a cleaning solution — usually a diluted sodium hypochlorite mix — to kill algae, mold, and mildew at the root rather than blasting it off the surface. It's the correct method for roofs, painted siding, wood, stucco, and anything that could be damaged by high-pressure water. High-pressure washing is for hard, non-porous surfaces: concrete, brick, pavers, and some fencing. If a company proposes high-pressure washing your roof or painted siding, that's a serious red flag — high pressure on a roof can drive water up under shingles, and on siding it can force water behind panels where it causes hidden rot and mold. The correct method costs about the same either way; the difference is technique, not effort.
Why Insurance Matters More Here Than for Most Home Services
Pressure washing carries real property-damage risk — etched concrete, killed landscaping from chemical overspray, cracked window seals from a nozzle held too close, or paint stripped off trim. Ask for a certificate of insurance before work starts, the same way you would for any contractor working around your home's exterior. A company that can't produce proof of general liability coverage is asking you to personally absorb the risk if something goes wrong. This is a reasonable, standard request — any legitimate operation can send a certificate within minutes.
Why the Cheapest Quote Often Means Damage, Not Savings
Pressure washing pricing scales with time, water usage, and the chemistry used for soft washing — a quote significantly below others for the same scope usually means one of three things: they're skipping pre-treatment (which means the cleaning won't last as long), they're using pressure settings that are faster but riskier for the surface, or they're not carrying insurance and pricing accordingly. None of those savings show up as a line item — they show up later as a driveway that needs to be redone in 6 months instead of 18, or as a repair bill for damage the low quote didn't account for. Compare quotes on scope and method, not just the number.
SC Pollen and Mildew Seasonality — Why Timing Affects the Quote
Lexington and the greater Columbia metro get heavy pine pollen coverage from late February through May, and the region's humidity accelerates mold and algae growth on siding, roofs, and shaded concrete year-round. A company familiar with the area should factor this into scheduling advice — spring pollen removal is often a bigger, dirtier job than a routine seasonal wash, and north-facing or heavily shaded surfaces typically need soft washing more often than sun-exposed ones because they stay damp longer. If a quote doesn't account for how much buildup is actually on the surface versus a flat per-job rate regardless of condition, ask why.
What Pressure Washing Actually Costs in the Lexington Area
For context: a standard two-car concrete driveway typically runs $150–$300 depending on size and staining. House exteriors (soft wash) run $250–$500 for a single story, more for two-story homes. Decks and patios run $200–$400 depending on material and size. Pricing is generally based on square footage and surface condition, not a flat number regardless of what's actually there — a driveway with years of oil stains and algae takes longer than one that just needs a seasonal refresh, and the quote should reflect that.

FAQ
Common questions about pressure washing
- What PSI should be used for a concrete driveway vs. house siding?
- Concrete driveways can typically handle 3,000–4,000 PSI with a surface cleaner attachment. House siding, especially vinyl or painted wood, should be soft-washed at low pressure (under 500 PSI) with a cleaning solution instead of blasted with high PSI, which risks forcing water behind the siding.
- Is soft washing more expensive than pressure washing?
- Pricing is generally similar. Soft washing trades lower water pressure for cleaning solution cost, so the total often lands in the same range as pressure washing for a comparable job — the difference is method, not typically price.
- Why is a pressure washing quote sometimes much cheaper than others?
- A significantly lower quote for the same scope often means skipped pre-treatment, riskier pressure settings used to finish faster, or no insurance backing the work. Compare what's included and the method being used, not just the total price.
- How often should driveways and siding be pressure washed in the Lexington area?
- Most driveways in the Columbia metro need it about once a year; shaded driveways may need it twice. House exteriors typically hold up 12–24 months between soft washes, though north-facing or heavily shaded walls that stay damp longer may need attention sooner.
