This I think is without doubt the biggest problem of housing and not just the old ones.
The evaluation of the spots from moisture, should be sought in case that has caused. There are various types of cases:
1. Infiltration for breakdowns in the plant
2. Infiltration weather events
3. Condensation
4. Presence of water infiltration into the soil.
Penetrations for breakdowns in the plant are the easiest to see but the most dangerous because it increases dramatically if s'inteviene immediately on the case. To find out, all faucets are closed and then opened one by one. If the leak persists then the problem comes from the plant thermal must then find the location of the plants
moisture stains on ceilings and extended onto the surrounding walls can be attributed to a failure in the plant sewer and more especially the grafting of discharges lead (Braga) if that old swell and deteriorate. In these cases, to find the source of water loss intercept points for the collection of pipes and the joining point of the column down.
The infiltration by weather events occur during rainy periods or for a long time and tend to dry out during periods of drought.
To resolve this problem just act on the roofs and pipes making sure that there are no roof tiles moved or broken in the case of asbestos cement sheets which are not cosume or even perforated. Today, the roofs are no longer manufactured because asbestos has been proven that its dust is harmful to health. It also checked the system
collection and disposal of water, making sure that rain gutters, and channels are free of cracks or separations and nell'innesto the underground network of disposal such leaks from spreading moisture on the walls nearby.
In the visit to the property this is one of the harder to see why it is important to get help or ask to be put in writing that there are no defects from weather infiltration, especially when it has just been painted. In some cases the paint is specially made to cover these damp spots.
stains from condensation are the most widespread but also more difficult to see. Normally form at the points where there are no water systems and are due to moist air present in that space. As a rule the most affected are the corners of rooms where you can see the formation of visible black mold in continuous expansion.
In this case, the first thing to do is to ventilate the rooms to better facilitate the exchange of air and secondly, the insulation must be improved. Especially in older homes, it is possible that the absence of an adequate coating of reinforced concrete structures, and then this causes water stains caused by the thermal bridge.
The stains from water infiltration from the soil should affect only the old houses as is required by law to build a crawl space with the aim to drain the water before it comes into contact with the wall.
These infiltrations are easy to see why forming a wet band at the base of the wall visible both inside and outside. To solve this problem is not exactly cheap, in fact most of the time you have to take the first specialized companies that measure the humidity level and then act on the walls by inserting a special liquid resin that is blocking an incline.
How many times have you happened to find this situation in the homes you've visited?
How many times have you happened to discover after purchase?
