Hi,

Looking to move to Almeria  in the near future,Iv read that properties can suffer with damp and mould in the winter months, my question is, what would be the chance of getting a property that has cavity wall insulation and damp proofing? or is this something you would have to do yourself?

kind regards

kim

Spanish houses are not built with cavity walls or damp proof courses.

Just keep the house heated in the winter and damp/mould shouldnt be a problem

You will find that the paint will come off the walls inside as fine dust.The only remedy is brush off and start again.Unfortunately everyone I have spoken to have the same issue.It's like the fourth bridge.Some partly tile the walls again this is not a permanent solution as the tiles often pop off the walls with the damp.

House we purchased was immaculate on viewing as it was newly redecorated, however we now have the same problem.

Hi, Happy new year.

Thank you for your reply, i have seen one or two properties for sale that have cavity wall insulation and damp proofing,i guess the Spanish are behind with saving energy.

Generally the Spanish builders don't put in a damp proof course because of the risk of damage by earthquakes whereby a damp proof joint in the construction creates a weak spot in the external wall that could be damaged during a tremor.

Hi 

Thank you for your reply, wow, earth quakes and tremors, sounds daunting does this happen very often? 
Or is the lack of cavity wall and damp proofing just a safety measure? 

Regards

Kim

Minor earth quakes/tremors are not uncommon but you rarely know anything about it as they are almost unnoticeable.

Houses are generally built to be cool in the hotter months rather than warm in the winter. Its just something that you have to live with in Spain.

As I said earlier if you keep the house warm in the winter months damp should'nt really be a problem

Hi Guys,

Couldn’t pass by without adding. I was a specialist surveyor for 12 years, particularly focussed on dampness and timber decay. I note some of the comments re installing a damp proof course and would point out that the majority of modern damp courses that are added after the fact, are chemical in nature, so can be added if you have the skills to do so.

If you are seeing flaking paint or plaster, this is as a result of ground salts coming to the surface in a process known as efflorescence.Simply brush off if this bothers you but it is a sign of rising or penetrating damp and will not “go away” on its own. The salts themselves attract moisture so will feel damp to the touch.

Condensation - and the associated mould, is something altogether different and is a result of an imbalance between heating and ventilation. This is why you tend to see the mould in unventilated areas such as cupboards or the corners of bedrooms, where ventilation (air circulation) is poor. Adequate heating AND ventilation is required to resolve. Mould should be cleared with a fungicide solution, not bleach. A good quality dehumidifier will also help.

Keep the house well aired even in the winter months as for the paint flaking of the walls clean the area first and before you paint it add glue to the paint mix it well it works wonders
