"Damp, mould, condensation, poor ventilation, cold rooms. These aren't bad luck, they're building problems with building solutions. I translate the science into things you can actually do, whether you're renovating, building new, or just trying to fix a room that never dries out."

What actually makes a home healthy?
A healthy home is warm, dry and well ventilated, with clean indoor air and materials that don't release harmful chemicals. After 40 years of building, I've found that most problems come back to one thing: moisture. Get moisture under control and you've solved most of the battle.
What causes mould in a house?
Mould needs three things: moisture, a surface to grow on, and time. In most homes the moisture comes from inside, from cooking, showers, drying clothes and simply breathing. When that moist air hits a cold surface, it turns to water, and mould follows. Leaks, rising damp and poor drainage outside are less common causes, but they need ruling out.
Does double glazing stop condensation?
Not always, and this is one of the biggest myths I come across. Double glazing keeps the glass warmer, but if the frame is aluminium without a thermal break, the frame itself stays cold and condensation simply moves there. Failed seals between the panes also reduce performance. Good glazing helps, but it works best alongside ventilation and moisture control.
What humidity should my home be?
Aim for 40 to 60% relative humidity for most of the time. Above 60% for long periods, mould and dust mites thrive; below 40%, the air feels dry and can irritate your eyes and airways. A simple digital hygrometer costs very little and tells you what's actually going on.
Who is behind Healthy Homes Guide?
I'm Ian Chamberlain, a builder with more than 40 years of hands-on experience. I started Healthy Homes Guide to share what I've learned about why some homes stay warm and dry while others struggle with damp and mould, in plain language, without jargon or scare tactics.
A big positive was Ian's communication skills before, during and after the project was completed. His communication with us and his team prevented misunderstanding and we felt we were all on the same wave length.
We would happily work with Ian and his team again.
Ian's team are a tightly disciplined group of professionals
I have to say that the level of professionalism shown by your staff has been extraordinary.
