Make each quote cover the same work
A useful comparison starts with a shared description of the job. List the rooms or items, approximate sizes where known, the material, visible condition and the result you are hoping for. For carpet, say whether stairs or a rug are included; for upholstery, identify each piece and the areas to be treated. Ask the provider to confirm what is included and what is excluded in writing.
A low total may describe a smaller scope, while a higher one may include additional items or preparation. Neither figure is meaningful until you know what work it represents. A material assessment matters too: the appropriate process can depend on fibre, construction, finish, condition and previous treatments. If an assessment could change the scope or price, ask how that will be agreed before work begins.
Check how the total is calculated
Ask whether the amount includes VAT, any call-out or minimum charge, and the items or areas that each amount covers. Do not assume that a quoted starting figure is a final total. If the quote is conditional on a site visit, measurements or photographs, find out which details still need confirmation and request an updated written scope before approving extra work.
Also discuss access and site costs. Parking, stairs, distance from a vehicle, building access rules or a long carry may affect what is practical. Clarify whether these are already included or could change the quote. Providers may handle such conditions differently, so compare the stated terms rather than guessing at a typical rate.
Agree on boundaries and next steps
Describe marks, delicate materials, damage and previous cleaning honestly. Cleaning cannot guarantee that every stain will lift or reverse wear, fading or damage; a clear assessment helps set a realistic scope. Ask who will confirm any change if the condition differs from what was described, and whether you can decline the additional work.
Before accepting, keep a copy of the quote and check the service date or follow-up process, access arrangements, preparation requests and payment terms. A short, itemised description makes it easier to spot misunderstandings later. Choose the option whose scope and conditions suit your needs, not simply the one with the least detail or the lowest initial figure.
