Planning your visit

Questions before booking

How do I choose an assessment?

Free photo identification is a first step. An inspection starts from £200; a survey with an agreed report starts from £300. Tell us what decision or document you need.

What is needed for a quotation?

An inspection is required before quoting for a ten-year plan, barrier membranes or excavation. Photos help us prepare but do not replace that inspection.

How often do you visit?

Treatment visits are every four weeks during the treatment season. Some other providers’ programmes may include only two treatment visits a year. The site programme determines timing and suitable work; monitoring forms part of management plans.

What about booking and deposits?

Deposits are required before booking. We confirm the scope, deposit and applicable terms before you commit.

What should I send?

Send the site address or postcode, clear photographs, access details and any sale or works deadline. Tell us about nearby water, existing reports and the documents you need.
