What actually determines the price
Two houses on the same street can have very different quotes. Reputable cleaners price on the real work involved, not a flat guess. The biggest factors:
- Size & square footage — more siding means more solution, water, and time.
- Number of stories — taller homes need more equipment and care, which adds labor.
- Siding type — vinyl, brick, stucco, wood, and Hardie board each take a different approach.
- Level of buildup — heavy green/black algae and mildew take more dwell time and product.
- Access & landscaping — steep lots, tight access, and delicate plants slow the job down.
- Add-ons — gutters, concrete, decks, and fences are often bundled at a discount.
Soft washing vs. pressure washing — why the method matters
If a company quotes you a rock-bottom price to 'pressure wash' your siding, be careful. High pressure can crack siding, strip paint, and force water behind your walls — turning a cheap wash into an expensive repair.
The industry-preferred method for siding is soft washing: low pressure plus specialized, eco-conscious solutions that kill mold and algae at the root. It costs about the same to do right, but the results last months longer and protect your home instead of risking it. Rally soft-washes every home.
Is house washing worth it?
For most homeowners, yes — it's one of the highest-return things you can do for your home's appearance. A professional wash removes years of grime in a few hours and instantly lifts curb appeal, which matters whether you're selling, hosting, or just tired of looking at green streaks.
Left alone, algae and mildew don't just look bad — they hold moisture against your siding and can shorten its life. An annual or every-other-year wash protects your single biggest investment for a fraction of the cost of replacing siding.
How to compare quotes (and avoid getting burned)
The cheapest quote is rarely the best value. Before you book, make sure you're comparing the same thing:
- Are they soft washing or blasting with high pressure? (Soft wash protects your siding.)
- Are they insured? Ask for proof — damage from an uninsured cleaner is on you.
- Is the quote itemized and in writing, with no vague 'starting at' pricing?
- Do they guarantee the results if you're not happy?
