Not everything needs a full survey. Sometimes the wall has been cleared and you want the readings taken again.

01

What you can book

  • Follow-up readings. Moisture readings against the grid in your quote, so the drying is tracked over the months.
  • A guarantee visit. Anything covered by our guarantee: material found in a cavity we cleared, a brick or joint we reinstated, an airbrick we sleeved.
  • A borescope check on someone else’s extraction. A look on every elevation and a short written note of what is there. If it is clear, the note says so.
  • A pre-sale or pre-refill check. Stills of the cleared cavity and current readings for the file.
  • A look at a new patch. Where damp has appeared after extraction and you would like it looked at before anyone else is called.

02

What it costs

Guarantee visits and follow-up readings for our own customers are free. A borescope check on another firm’s work, or a pre-sale check on a house we have not worked on, is quoted before we come, by email, once we know the house and the number of elevations.

03

How to book

Email [email protected] with your address, whether we have worked on the house before and the date on the completion certificate if so, what you would like looked at, and photographs if there is something to see. Or use the contact form and choose “service call”.

04

What you get afterwards

A short note by email with what was found, the readings or stills, and what if anything we suggest. If the visit was under guarantee and something was ours, it is fixed on the day where it can be and booked in where it cannot.

If what you actually need is the full survey, the quote and a quotation, that is on the free survey page and costs nothing either way.

What happens next

  • A free survey first We check the wall inside and out and look into the cavity with a small camera. Then you get a fixed price in writing.
  • The insulation comes out Bricks come out at the base of the wall, the old fill is drawn out, and the bricks go back in, pointed to match.
  • A completion certificate You receive a completion certificate when the work is done. If a lender or surveyor has flagged a filled cavity, that certificate is what you show them.
