10 Questions to Ask Before Hiring a Jet Washing Company

Ask whether they're insured before anything else. Any legitimate exterior cleaning company should carry public liability insurance — ask to see proof. This protects you if anything goes wrong during the job. Equally important is to ask about their experience with your specific surface type. Cleaning Indian sandstone is different from cleaning concrete, and you want a company that understands these differences.

Ask how they quote — is it a fixed price or an estimate? A professional who has seen the job should be able to give you a fixed price. Day rates or open-ended estimates leave you exposed. Ask what products they use and whether they're appropriate for your surfaces. Also ask whether the price includes pre-treatment, post-treatment, and waste disposal — or whether these are extra.

Ask for local references or reviews. A company that regularly works in your area should be able to point you to reviews from local customers or provide references. Ask what happens if you're not happy with the result — a confident professional will have a clear answer. Finally, ask when they can do the job — availability in your preferred timeframe is a practical consideration that determines whether you proceed.
