Demos
Try it working, before you buy anything.
Every demo on this page is live. No mock-ups, no videos. The real thing, free to use, no sign-up, nothing stored. They are smaller cousins of the builds Allan sells. Click one and put it to work.

Watch it work
Price a job before you quote it.
The real jet-washing estimator from this site — typing in the area, the postcode and the condition, and the price band moves with them, live. Click in any time to price your own.
Surface type
Robust, but the joints hold weeds and moss and shed sand as they clean — careful work, and the jointing sand usually needs topping up after (see sand re-fill).
Know your own rate?
If you already know your price per square metre, enter it here and we’ll use it instead of our surface rates. Leave it blank to use our estimate.
Area
Enter dimensions OR a known total. Whichever is easier for you.
Location
Enter your postcode and we adjust the estimate for regional pricing — based on ONS wage data for your area.
Condition

Optional extras
Cleaning more than one surface?
Add your patio, paths, or another area. Two or more surfaces cleaned in the same visit get a 15% bundle saving.
Calculators
Price it on the spot
Working calculators. Type a job in and watch the number move. On a client build, this same shape becomes the instant-quote widget on your own website: a visitor describes their job and gets a price band before they pick up the phone.
Documents
Paperwork, built in the browser
Forms in, finished paperwork out (invoices, signed job records, visit logs), generated on your device with nothing stored on a server. The same pattern as the document generators and job-record tools Allan builds to order.
Integrations
A live map, dropped in
The same Google Map that would sit on your contact page, embedded here pointing at a public landmark, because this is a demo, not an address book. Note how it loads: only when you ask it to. Your visitors’ data does not go to Google by default on a NOXEB build.
The rest
Not everything fits on a demo page
AI bots, booking systems, and automations get built per client, wired into that business’s calendar, CRM, or phone line, so a generic demo would tell you very little. The price tool covers all of them: the £ Get a rough price button in the corner of this page gives you a range in about a minute, and Allan reads every enquiry himself.
