Do you have damp stains on the walls, mould in the corners or a leak that nobody has been able to fix?
This is the only guide on the market with real cases, proven technical solutions and real construction budgets — written by an architect with 20 years of experience resolving exactly these problems.
The problem is never the damp. The problem is the wrong diagnosis.
A residents association spent £18,000 on external facade work that resolved nothing. The correct solution cost £1,200 and was inside the flat. A nearly new flat roof quoted for full renewal at £30,000 was repaired with a localised fix for £150. A ten-year leak was resolved in two hours for £45.
What you will find inside:
✅ The 6 types of damp explained with real technical expertise — rising damp, penetrating damp, condensation, roof leak, terrace leak and mould
✅ Quick diagnosis table — symptom, likely damp type and solution at a glance
✅ 3 options for rising damp by budget — liquid membrane, perimeter drainage or full floor renovation
✅ Thermal bridges explained with the exact condensation temperature — 12.5°C — and why mould always appears in the same places
✅ 4 ventilation solutions with real installed prices — trickle vents, grilles, passive roof ventilators and mechanical extractors
✅ Water repellent facade treatment step by step — cleaning, primer and two coats
✅ How to detect damp when buying a property — what to look at, where to look and what to ask
✅ Annual preventive maintenance — what to check to prevent problems before they appear
✅ The 6 most expensive damp mistakes homeowners make
✅ Composite real budget — typical property with three simultaneous problems: leak + condensation + rising damp. £13,834 itemised line by line
✅ All unit prices EXCLUDING VAT and Building Regulations fees
Who this book is for: — Homeowners with stains, mould or leaks who do not know what is causing them — Homeowners who have called companies that have not resolved the problem or have given them inflated quotes — Residents associations with chronic unresolved damp problems — Property buyers who want to detect problems before exchanging contracts
Why trust these solutions and prices: Not written from an office. Written by a qualified architect who spent years as a maintenance contractor for a social housing provider, resolving hundreds of real damp and condensation cases in rented properties. The cases, the budgets and the prices are real. The stories are his own.
All prices excluding VAT and Building Regulations fees — so you can calculate the real cost of resolving your problem yourself.
