The Financial Cost of Waiting
A damp problem found early is usually a modest repair. Left alone, it rarely stays that way.
Active damp extends the scope of repair
Active damp typically extends the replastering scope the longer it is left. Saturated plaster softens and detaches.
A small repair grows to £5,000 or more
Moisture spreads to nearby timber. A repair that costs a few hundred pounds in year one can grow into structural work exceeding £5,000.
Flags on a mortgage valuation
Untreated damp also flags on a mortgage valuation. For anyone buying, selling or remortgaging, that flag stalls the process and gives the other party an opening to negotiate on price.
A free survey is the cheapest way to know where you stand.
What Damp Proofing Involves
Damp in a Newcastle property can arrive from several directions. The right treatment depends on the correct diagnosis.
Diagnosing the actual cause first
Ground moisture may be rising through the base of the wall, water entering through failed pointing, or condensation forming on cold internal surfaces. Often more than one factor is active at the same time.
Chemical injection for confirmed rising damp
Where rising damp is confirmed, we drill the masonry at low level and inject a water-repellent chemical. This creates a new moisture barrier inside the wall.
Replastering with salt-resistant materials
We remove the affected plaster and replaster using salt-resistant materials. Our rising damp treatment page explains how we distinguish between the different cause types in practice.
External faults resolved before internal work
Where water is entering through the external envelope, the external fault must be resolved before any internal work begins. Internal treatments alone are not a cure for penetrating moisture.
After treatment, walls need time to dry before final decoration. We tell you a realistic timeline before work starts.

Is the Free Survey Just a Sales Visit?
It is a fair suspicion. Most free surveys in this trade operate as sales calls.
The conflict is real
The surveyor arrives knowing their employer needs to sell work. That structure shapes what they find.
Ours is structured differently
If your problem is condensation rather than structural damp, we say so. If there is no issue at all, you leave with a written all-clear and a zero invoice.
We identify the correct cause
Our types of damp guide explains how we distinguish between damp types before any recommendation is made.
Will the Damp Come Back?
Damp returns when the source is not fixed. Surface treatment applied over an active moisture source produces results that last months, not years.
Treatment fails when the diagnosis is wrong
Chemical DPC injection does not resolve penetrating damp. Replastering over a wall that is still wet does not cure rising damp.
We check the moisture source before confirming the cause
If the moisture source beneath the plaster is still active, the problem returns. We carry out moisture checks at the source before confirming the cause and recommending treatment.
External factors are flagged in the report
Where external factors are involved, such as failed guttering or cracked pointing, we flag these in the survey report. Addressing the external cause first is often the least expensive step.
