Damp or mould can appear for many different reasons, and what you see on the surface isn't always where the problem begins.
We inspect damp, mould, condensation and moisture problems to understand what is really happening in your home.
We explain the likely cause, what needs attention, and which solutions are most suitable for your property.
Where work is needed, we can guide you through practical solutions designed to resolve the issue and reduce the risk of it returning.

Damp, mould and moisture problems can look similar, but the causes are often different. These guides help you recognise common signs. The right solution depends on the property, the symptoms and where the moisture is coming from.
Condensation happens when warm, moisture laden air meets colder surfaces, often leading to water droplets, mould and musty smells.
Typical Signs
How We Check It: We review humidity, ventilation, airflow, cold surfaces and how the room is being used before recommending the right next step.
Penetrating damp can happen when water enters from outside through defects such as brickwork, pointing, render, gutters, roof junctions or window areas.
Typical Signs
How We Check It: We review the outside of the property, rainwater routes, visible defects, moisture patterns and the areas affected inside.
Rising damp is associated with moisture moving up from ground level, often showing as low level staining, salts or damage near skirting boards.
Typical Signs
How We Check It: We review moisture levels, salts, wall construction, ground levels, bridging and whether another cause could be creating similar symptoms.
We keep the process simple: understand the symptoms, identify the likely cause, then recommend the right solution for your home.

We have no financial interest in what remediation you choose.
No Affiliated Products

Mrs K Smith

"We had wall ties replaced after our surveyor flagged failure. CRS scaffolded, drilled, fitted and made good in less than a day. The mortar match is invisible."
