Hi All,
Another post regarding damp but with a few other points.
We live in a bungalow which was built in 1964.
It has an under floor void of about 24" and this is screeded.
The house is built on clay where the top of the foundation is level with the top of the clay. I suspect they filled the footing to that level. The garden is on a slope so groundwater has a tendency to migrate toward the house.
We get quite a lot of condensation on the bedroom windows in the morning. I've looked at many of the other topics and understand that air humidity is the primary cause. The humidity in the bedrooms is about 60-70% most of the time.
When we were redecorating/renovating the house we noticed that there was standing water (about 3/8") over the underfloor in the bedrooms.
This could obviously be a cause of condensation but if the air bricks work properly the humidity above the water should be the same as the outside and not add additional moisture. Does this sound correct given that the rooms are sealed pretty well against drafts from below?
When the cavities were insulated the workmen fitted upside down U's along the top and side of the air bricks to stop the insulation blocking them. Would this seriously affect the ventilation?
Would replacing the air bricks with the tube/channel type improve things greatly or would it be a waste of effort.
We are adding some drainage to the garden to bypass some of the water to the front of the house to alleviate some of the potential damp issues.
Any comments would be greatly appreciated
Andy
