Pressure washing can be one part of exterior care, but suitability cannot be inferred from dirt alone. Start with material, construction, condition, coatings and where the water will go.
Suitability
Block paving, concrete, natural stone, porcelain, brick and coated surfaces do not share one pressure setting or cleaning sequence. A real assessment should identify the material, defects and any manufacturer or installer constraints.
Method limits
A surface that looks robust from a distance may have vulnerable joints, soft areas or adjoining finishes. Render and timber deserve their own method conversation, while thresholds, vents and electrical fittings need deliberate protection.
Runoff
Water can carry sediment, organic matter and cleaning residues. Map surface drains, soakaways, foul or combined connections, garden borders and neighbouring land before the provider chooses controls or a disposal route.
After cleaning
A useful quote distinguishes washing from optional re-sanding, sealing, treatment or repair. It should also state which stains may remain, what drying period matters and who is responsible for moving items or restoring access.

Questions
No. Material, condition, joints, coatings, edges and drainage need assessment. Lower force, another method or an exclusion may be more appropriate for some areas.
Not automatically. Joint re-sanding, sealing and treatment are separate scope items that a real provider should describe, price and schedule explicitly.
No universal result can be promised. Stain type, age, depth, surface porosity and previous attempts affect what may be practical without damaging the substrate.
The route depends on what the water contains and the site drainage. Current GOV.UK guidance says contaminated water must not cause pollution and only clean water should enter surface drains or soakaways.
No. It is general enquiry-preparation content, not a site-specific risk assessment, method statement or environmental plan.
