Re: Brand new house - Rising damp issue 13May 29, 2019 3:26 pm Possible it's the water trickling over the window sill and leaving salts deposits , have you got other brick window sills with same efflorescence issue underneath? Re: Brand new house - Rising damp issue 14May 29, 2019 3:28 pm Because if you look at the aluminium frame it too has what looks like white powdery salt deposits , possibly from water trickling down from above?? Just a theory. Re: Brand new house - Rising damp issue 15May 29, 2019 4:50 pm The white stain seems to be originating from the grout, I think it’s called efflorescence and is commonly associated with concrete bricks. I think you can get a product at hardware stores to get rid of this stain and seal the bricks. I don’t think it’s rising damp.

This is exactly what the agent and the representative from builder said and he said it is very common with such types of bricks. I just want to have some piece of mind, where some one " licenses inspectors" assess it and confirms its just a brick issue. Re: Brand new house - Rising damp issue 18May 29, 2019 7:22 pm Why not get a treatment for efflorescence, if it continues to come back or you notice other evidence, then request another inspection. Have a look when it rains as well and see where the water is trickling. Re: Brand new house - Rising damp issue 19May 29, 2019 7:36 pm From my experience the efflorescence is a results of excess water then drying which leaves the residue so the problem may not be there now.Was it a wet period during the construction with poor drainage and no temporary downpipes? I would get a soil test next to your perimeter wall with soil moisture content testing from a geotech company.I noticed you have pebble landscaping, this is a bad idea especially with a H1 soil type.The pebble landscaping will allow water to penetrate into the ground and then restrict evaporation gradually leading to an increase in soil moisture around the perimeter of the house.Apart from rising damp this can lead to slab heave, I would remove the pebbles and either grade the soil away from the house or place plastic down which grades way from the house and then put landscaping material on top.

I am still in the pre purchase stage where I have signed a contract and I have building and pest condition for 21 days, I have another 14 days left to arrange an inspection done by a specialist and find out what the issue is and also suggest a remedy. The builder says there is no issue but he is happy for us to do what ever tests within the next 14 days. If you can suggest if I should engage a plumber ? Damp specialist? Concrete specialist? Or a structural engineer then i can take the next course of action.
