Methodology and limitations
- Sources: only the business’s own website or rate sheet. No reviews, directories, forums or quotes we requested. We did not contact any business.
- Sample: 3 published prices from 2 businesses on 2 pages. This is the set we could find, not a survey or a random sample, and many businesses don’t publish prices at all.
- Dates: we read every page on 2026-11-11. 0 of the pages carry a date or fiscal year, 0 show only a copyright year, and 2 have no date. Each price below shows what its page said.
- How we summarize: prices are grouped by unit (per foot, per hour, flat, per visit, per gallon) and by kind of job, and never mixed. The range runs from the lowest published price to the highest. The median gives each business one vote (the middle of its own range), so a yard with many size tiers doesn’t outweigh a diver with one price. Where a business wrote “starting at”, we used that figure, so real bills are often higher.
- Region pages exist only where at least 3 published prices from 2 or more businesses are available.
- Your quote may differ. Condition, access, season, and what’s included all change the price. Use these figures to ask better questions, not as a price promise.
