Damp Proofing Northampton

Damp has a habit of being blamed on the wrong cause, and treating the wrong problem doesn't just waste money, it can leave the actual issue to keep getting worse behind a fresh coat of paint or plaster. We carry out damp proofing across Northampton and Milton Keynes, starting with a proper diagnosis of what's actually causing the problem.

Types of Damp

Condensation is, by a wide margin, the most common cause of damp problems in UK homes, and it's frequently misdiagnosed as rising or penetrating damp, leading to unnecessary and ineffective treatment. Getting the diagnosis right before any work starts is the single most important part of dealing with damp properly.

  • Rising damp, moisture drawn up through a wall from the ground, often due to a failed or missing damp proof course

  • Penetrating damp, water getting in from outside through a specific defect, such as damaged render, failed pointing, a leaking gutter or a roof problem

  • Condensation, moisture from everyday living, cooking, showering, drying clothes, condensing on cold surfaces, often mistaken for rising or penetrating damp but requiring a completely different solution

What Diagnosis Involves

  1. An inspection of the affected area, both internally and externally where relevant

  2. Checking for external causes such as damaged render, failed pointing, blocked or leaking guttering, or ground levels sitting too high against the wall

  3. Assessing ventilation and everyday moisture sources where condensation is suspected

  4. A clear explanation of the likely cause before recommending any treatment

Treatment Options

  • For rising damp: installing or repairing a damp proof course, and appropriate replastering with a suitable render or plaster system

  • For penetrating damp: fixing the specific external defect causing water ingress, whether that's brickwork, render, guttering or roofing

  • For condensation: improving ventilation, and addressing the everyday moisture sources contributing to the problem

Why Choose Bridgework

  • Proper diagnosis before any treatment, rather than assuming the most common (and most profitable) cause

  • Fixing the actual external defect where penetrating damp is the cause, not just treating the symptom internally

  • Honest advice where condensation and ventilation, not a damp proof course, is the real issue

  • A clear quote before work starts

Damp Proofing FAQs

Rising damp typically affects the lower portion of a wall, often with a visible tide mark, and doesn't usually go above around a metre from the floor, while condensation commonly appears higher up, on cold spots like external corners, around windows, or on ceilings, and tends to worsen in cold weather or after cooking and showering. A proper inspection can confirm which is actually present.

It's far less common than it's often assumed to be, condensation and penetrating damp from a specific external defect account for the majority of damp problems in practice. This is exactly why proper diagnosis matters before committing to a damp proof course treatment.

It depends on the cause and how far the damp has already affected the existing plaster. Where plaster has been damaged by rising or penetrating damp, replacement with an appropriate system is often necessary alongside fixing the underlying cause.

This varies considerably by the cause and extent of the problem, from a straightforward external repair taking a day or two, to a fuller damp proof course and replastering project taking longer, plus drying time before decoration.
