Damp Proofing Patchway Bristol

B&D Plastering Bristol, Quality You Can See

B&D Plastering provides damp proofing in Patchway across Bristol’s post-war housing stock, much of it built in the 1950s and 1960s to house the workforce at the former Bristol Aeroplane Company. That housing is now between 60 and 70 years old, and one of the most common things we find on a Patchway survey is damp that was plastered over in the past rather than properly treated.

This page covers our damp proofing services for Patchway homeowners. For plastering specifically, see our dedicated plastering page. Call Dave on 07754 246 461 for a free, no-obligation survey. We are available Monday to Saturday, 7am to 8pm.

Why Damp Keeps Coming Back in Patchway Properties

Patchway’s post-war housing has needed a lot of replastering over the years, and when we strip a wall back during a full replaster, we regularly find the real explanation for why the plaster failed in the first place. In a significant number of cases, a previous job plastered straight over an area of damp rather than identifying and treating the cause. This masks the problem for a while, but the moisture keeps moving through the wall behind the new surface, and it eventually shows through again, often within a year or two. Treating the actual source before any replastering begins is the only way to get a result that lasts.

Damp Risk in Patchway’s Post-War Housing

Penetrating Damp in Ageing Walls

Much of Patchway’s housing stock is now 60 to 70 years old, and decades of weathering take a toll on pointing, render and window seals. Penetrating damp, water entering horizontally through the wall rather than rising from the ground, is one of the most frequent issues we treat here. It typically shows up as patches that worsen after heavy rain, and it is often mistaken for rising damp until a proper survey confirms the cause.

Rising Damp Where the Original Barrier Has Failed

Properties from this era usually had a physical damp proof course installed when they were built, but after six or seven decades these frequently break down, or in some cases were never continuous around the whole property. Where we find a failed or absent barrier, we install a chemical damp proof course to create a permanent replacement.

Damp Plastered Over, Not Treated

This is the pattern referred to above, and it is worth its own section because of how often we encounter it in Patchway specifically. Signs include a damp patch or tide mark reappearing through recently decorated plaster, a musty smell that returns despite redecoration, or staining that bleeds through fresh paint within months. Where we find this, we remove the affected plaster back to bare masonry, identify and treat the actual source of the moisture, and only then re-render and skim.

Our Damp Proofing Process in Patchway

Every damp job in Patchway starts with a proper survey using a calibrated damp meter, not a sales visit. We confirm the type of damp present, its source and how far it has spread, and give you a straight answer, including telling you if a previous plastering job masked rather than solved the problem. Treatment typically involves a chemical damp proof course for rising damp, tanking for penetrating damp or basement water ingress, and re-rendering to a smooth, sound finish ready for decorating. For the full detail of our process, see our main damp proofing page

Frequently Asked Questions, Damp Proofing Patchway

We had a damp patch plastered over a few years ago and it has come back, why?
This is one of the most common calls we get in Patchway. Plastering over damp without treating the underlying cause only masks the problem temporarily. The moisture continues to travel through the wall and eventually shows through the new plaster again, often within a year or two. We always identify and treat the actual source before any replastering begins.
Our 1960s Patchway house does not seem to have a damp proof course, is that normal?
Many properties from this era in Patchway did have a physical damp proof course installed originally, but after 60 to 70 years these frequently break down or were never continuous around the whole property. Where we find this, we install a chemical damp proof course to create a permanent replacement barrier.
How do I know if my Patchway property has rising damp or penetrating damp?
Rising damp shows as a band low on the wall, usually below a metre, often with staining or salt marks. Penetrating damp appears as isolated patches that worsen after heavy rain, more commonly on walls exposed to prevailing weather. We use a calibrated damp meter to confirm which is present during every survey.
Can you treat damp and replaster in the same job?
Yes, and for Patchway properties this is usually the correct approach. Where we find damp, we treat it first, either a chemical damp proof course, tanking, or both depending on the type, then re-render and skim once treatment is complete. Doing both in one job means a lasting result rather than a repair that fails again.
Do you offer a free damp survey in Patchway?
Yes. We offer a free, no-obligation damp survey across Patchway using a calibrated damp meter. We will give you an honest assessment of what we find and what it means, and if damp is not actually the issue, we will tell you that too.
