This page explains how DIY Damp content is produced, sourced, and corrected, so you can judge how much weight to give it.
Our sourcing standard
Specific claims should carry a source. When an article states a humidity threshold, a health effect, a drying time, or a cost range, we link to published guidance rather than asserting it. The sources we lean on most:
- U.S. Environmental Protection Agency — mould remediation, indoor air quality
- Centers for Disease Control and Prevention — health effects of damp and mould
- U.S. Consumer Product Safety Commission — appliance and equipment safety
- Building-science and construction research for moisture movement, vapour behaviour, and drainage
How articles are written
Every article starts from the sources above rather than from opinion. Factual claims — humidity thresholds, drying times, health effects, cost ranges — are checked against published guidance before publication, and anything we cannot support with a source is removed rather than softened into a vague sentence that sounds authoritative and says nothing.
Where the guidance genuinely varies — by climate, soil, construction era, or local code — we say so instead of picking one answer and stating it flatly. Damp is a local problem, and a guide that pretends otherwise is not being helpful.
Cost figures are ranges gathered from published sources at the time of writing. They are labelled as estimates, never presented as quotes, and they are the part of any article most likely to drift out of date — treat them as a starting point for your own research, not a number to hold a contractor to.
This is also why the corrections policy below is not decoration. It is the main mechanism by which this site gets more accurate over time, and we would genuinely rather hear that something is wrong than not.
What we do not do
- We do not sell waterproofing, remediation, or any service covered in our articles.
- We do not sell or broker contractor leads.
- We do not accept payment for reviews, recommendations, links, or guest posts.
- We do not present a product or method as the answer because someone paid for it.
Corrections policy
If something here is wrong, we want to know. Email umar.bwn@gmail.com with the page and what is inaccurate. Substantive corrections are made to the article and noted on it, rather than quietly edited away. Every article carries a last-updated date so you can see how current it is.

DIY Damp is general information, not professional advice. It cannot inspect your house, it does not know your soil, water table, climate, or construction, and it is not a substitute for a qualified contractor, structural engineer, or physician. Structural damage, electrical hazards, sewage, and health symptoms all need a professional. See our disclaimer.
