Damp Proofing Aylesbury
Expert damp proofing specialists serving Aylesbury and Buckinghamshire. Rising damp, penetrating damp, dry rot and woodworm across HP20, HP21 and surrounding postcodes.
Damp Problems in Aylesbury Properties
Aylesbury's property mix spans Victorian town centre terraces, 1930s semis, post-war estates and the newer developments around the southern expansion areas. Each housing type presents different damp challenges — from classic rising damp in Victorian stock to penetrating damp in flint cottages in surrounding villages.
The older properties around Walton Street, Bourbon Street, Cambridge Street and the Aylesbury Conservation Area are particularly prone to rising damp from failed original DPCs. The chalk and clay geology of the Vale of Aylesbury means ground moisture is a persistent issue across HP20 and HP21. Our Buckinghamshire team is based nearby and can typically attend within 24–48 hours.
📋 Recent Job — Bourbon Street, HP20
1900s brick terrace — rising damp at 950mm — salt analysis showed the wall had been injected previously with an ineffective product. Re-injected with Dryzone cream DPC to BS 6576 and salt-inhibiting render applied. Guaranteed for 20 years.

Important: Different types of damp need completely different treatments. A professional survey is essential — treating the wrong type is one of the most common and costly mistakes made by non-specialist contractors.
How We Treat Rising Damp Case Study — Aylesbury
Rising damp is the most common problem we treat in Aylesbury's Victorian and Edwardian properties. Here is exactly how we treat it — the same process we carry out across the town centre and Walton and all surrounding areas.
Moisture Profiling & Salt Analysis
We use a calibrated electronic moisture meter to build a moisture profile across the affected wall at regular height intervals — typically every 150mm from floor level to 1.5m. We also take plaster samples for laboratory salt analysis where required, identifying hygroscopic chloride and nitrate salts that confirm rising damp rather than condensation or penetrating damp. This diagnostic stage is essential — treating the wrong type of damp is a common and costly mistake.
Preparation — Skirting Removal & Plaster Strip
All skirting boards are carefully removed and set aside or replaced. Contaminated wall plaster is hacked off to a minimum height of 1.2m above floor level — or higher if the moisture profile indicates the damp has risen further. This is non-negotiable: leaving salt-contaminated plaster in place and simply applying a new coat over it is the most common cause of rising damp treatment failures we see where previous contractors have cut corners.
Chemical DPC Injection to BS 6576
We drill a continuous series of holes at 120mm centres into the mortar bed course, typically at 150mm above external ground level. A high-performance silane/siloxane cream or liquid damp-proof course is then injected into each hole under controlled pressure, where it diffuses through the masonry pores and polymerises to form a continuous water-repellent barrier. All work is carried out to BS 6576:2005 — the British Standard for chemical DPC installation. Aylesbury's Victorian solid-brick walls are typically 225mm (9-inch) thick, requiring injection from both faces where access allows — standard practice across all HP20 and HP21 properties we treat.
Replastering with Renovating Plaster
Standard gypsum plaster cannot be used on walls that have been affected by rising damp — the hygroscopic salts will bleed through it within months. We rerender using a specialist renovating plaster system specifically formulated to tolerate residual moisture and salt contamination during the drying-out period. The background is first treated with a salt-inhibiting primer, then a 10–15mm undercoat of renovating render is applied, followed by a finishing coat. The wall is then left to dry out fully — typically 1mm per day of wall thickness — before any redecoration.
Written Guarantee & Completion Report
On completion you receive a written guarantee for the damp-proof course installation, backed by Quality Mark Protection insurance. We also provide a completion report documenting the treatment carried out, the products used (with data sheets), and the expected drying-out timescale. This documentation is important for property sales — solicitors and surveyors regularly request evidence of DPC treatment, and our guaranteed reports satisfy these requirements in full.
Note on drying times: A fully treated wall in a Aylesbury Victorian terrace will typically take 12–18 months to dry out completely — 1mm of wall thickness per day is the standard guideline. This is completely normal and does not affect the effectiveness of the treatment. We advise clients to use breathable emulsion paint only during the drying period and to avoid impermeable vinyl wallpapers which can trap moisture.

What Affects the Cost of Damp Proofing
Damp proofing costs vary significantly depending on the type of problem, extent of the damage and the specific property. We always carry out a survey before providing a quote — so you get an accurate price for your specific situation, not an average estimate.
Type of Damp
Rising damp, penetrating damp and condensation all require different treatments with different costs. Accurate diagnosis from a survey is essential before any quote can be given.
Extent of the Problem
A single affected wall costs significantly less than multiple rooms. The height damp has risen and the amount of replastering required are the main cost drivers for rising damp treatment.
Survey First, Quote Second
We always survey before quoting. This means your quote is accurate and specific — not based on average job sizes. Fixed price, no day rates, no hidden extras.

Basement & Cellar Waterproofing in Aylesbury
Properties in Aylesbury with basements, cellars or lower-ground floor spaces often require structural waterproofing rather than standard damp proofing. Where water is entering through below-ground walls or floors under hydrostatic pressure, a dedicated waterproofing system is needed — cavity drain membranes or cementitious tanking depending on the ground conditions and intended use — Aylesbury's clay geology creates variable hydrostatic pressure that requires proper assessment before any system is specified.
Advanced Damp carry out structural waterproofing to BS 8102:2022 across Buckinghamshire. See our basement waterproofing page →
