Moisture Surveys in Banstead

Objective measurement of moisture levels in walls, floors and timber, documented for evidence.

A moisture survey is a measurement exercise rather than a repair proposal. It answers a specific question — how wet is this structure, and is it drying? — with calibrated instruments and a documented methodology. Landlords, purchasers, insurers and managing agents all use them to establish facts before decisions are made.

We record surface and deep readings, air temperature, relative humidity, dew point and material moisture content, and can repeat the survey at intervals to demonstrate a drying trend. Where flooring is to be installed, we carry out hygrometer testing of screeds to confirm they are ready.

Common signs

  • Uncertainty about whether a structure has fully dried
  • A dispute between landlord and tenant about damp
  • A homebuyer report recommending further investigation
  • Flooring failures suspected to be moisture related
  • Insurance drying said to be complete but doubt remains

Likely causes

  • Residual construction moisture in new builds and extensions
  • Historic leaks that were dried informally
  • Hygroscopic salts holding moisture in plaster
  • Ground moisture beneath solid floors
  • Persistent condensation raising material moisture content

Our method

How we diagnose and resolve the problem

01

Define the scope

We agree what needs to be measured and why, so the report answers the actual question.

02

Baseline readings

A full grid of readings is taken and photographed with locations marked on a plan.

03

Comparison and analysis

Readings are compared against unaffected control areas and recognised benchmark levels.

04

Reporting

A concise written report sets out the data, the interpretation and any recommended action.

Our reports are factual and independent, which is exactly what is needed when they will be read by a third party.

Questions

Moisture Surveys FAQs

What is an acceptable moisture reading?

It depends on the material. We always compare against a dry control area in the same property rather than relying on a single number.

Can you survey before laying a new floor?

Yes. Screed hygrometer testing to the relevant standard prevents costly flooring failures.

Do you provide reports for disputes?

Yes, we produce clear, evidence-based reports suitable for landlords, tenants, agents and insurers.
