We have mentioned this before Insulation in your home but it is worth mentioning it again.
Just in case you are not aware of this most houses and apartments in Portugal are not adequately insulated. To be more precise most houses in Portugal built during the time when building regulations were in force either don’t have the correct thickness of installation or any at all.
Then you have those modern homes which were built by a builder not fully understanding the correct way to install this new fangled, expensive and unnecessary insulation stuff. So they insulate badly and leave lots of areas know by professional builders as “cold bridge points”.
Then of course you have the cowboys who build your house and just put some insulation around the window and door openings so that the home owner can see it. They do this to save a few hundred Euros (that is them making the saving not you). Were you to find out and take them to court you would be wasting your money and considerable time, you would also not be the first person in your area to try this.
We are often amazed that when we are called in to do some work on existing expensive homes we may open up the wall and find that there in no insulation or there is a low cost substitute that looks like insulation but isn’t.
This picture shows the circle of insulation that we cut out of a wall when drilling a hole for a pipe to go through. It is insulation so the owner is happy. The trouble is its not the correct thickness!
Damp problems are by far the most common problem effecting and devaluing Portuguese homes and most people complain that its because they dont use a DPC or damp proof course. Neither do a lot of other European countries by the way.
No its not really the “rising damp problem” which many people talk about it is in fact Condensation.
Condensation in Portuguese homes houses and apartments is a massive problem. There are a hundred products on the market to temporarily hide the problem which shows how common it is. Home owners have often been living with condensation related damp miserably for years.
If you are living in a home with black mould on the walls, ceilings and that heavy muggy sensation when you enter a room there is a high likelihood that you have a condensation problem.
In tandem with the high humidity is Black Mould.
Black Mould is not really a damp problem but it is often the first ugly sign which make people react and do something about it. Apart from its ugly appearance, negative medical connotations and indication that your home is damp it is just not nice to live with.
There are two reasons why you have these problems. Cold, poorly insulated external walls and poor ventilation. Fix these two and it will transform your home.
