What’s the difference between condensation and damp?
When you look around a house, condensation and damp are two of the most important warning signs to watch out for.
Both can be signs of a deal-breaker, although more commonly, they can be worked with. Implementing a management plan of some kind will help vanquish any potential problems.
This article will compare the two. What is the difference between condensation and damp? They’re both forms of moisture in homes, yes, but there’s a slight variation in terminology to be aware of.
Does damp matter in a home I view?
Damp is an umbrella term for the presence of moisture or ‘dampness’. It’s widespread in the British Isles due to the high humidity all year round. If houses aren’t built (or modified) with adequate ventilation and moisture control methods, damp can cause severe problems. The three most common types of damp in residential properties are:
- Rising damp
- Penetrating damp
- Condensation (more on that in the next section)
There are a few tell-tale signs of damp. For example, a musty smell or mould on the walls. You could also watch out for condensation (see below).
Rising and penetrating damp are more common in older properties, before building regulations became stricter. Technology has since advanced so that new homes shouldn’t suffer from these. Still, it’s always worth getting a chartered surveyor to check it out, just in case.
What is condensation in a property?
Condensation is a type of damp. It’s when warm, moist air meets a cold surface. As it rapidly cools, water droplets deposit from the air onto the material, whatever it may be.
Glass and metals are two of the most common places to spot condensation. These tend to stay cooler than the surrounding materials and atmosphere. Look for condensation on windows, mirrors, and metal surfaces (particularly those higher up in your rooms).
Condensation is a problem because it means the moisture in the air probably has nowhere to go. If a house has been appropriately designed, extractor fans, roof design and possibly air conditioning systems or dehumidifiers should all contribute to extracting this moisture. Of course, they can’t be expected to remove it all, but there shouldn’t be enough for consistent condensation.
What’s the difference between condensation and damp?
Damp is a term encompassing all different types of moisture presence. Condensation is a type of damp.
Condensation is more likely to form in colder months, since this is when metals are coolest in relation to any hot, moist air. Rising and penetrating damp, if present, will be seen in wetter months.
All sources of damp need to be controlled or eliminated in some way. For example, getting a bit of condensation in a bathroom is perfectly normal. Showers create much more hot, humid air than baths, so suitable measures are critical. The kitchen is another place you’d expect to find more moisture. Boiling water in pots and kettles and doing the dishes using the hot tap contribute. These rooms, of course, must stay.
However, introducing measures like extractor fans or, in severe cases, dehumidifiers can help keep humidity levels down. This reduces condensation and damp, meaning you’re far less likely to find problems in the future.
The importance of getting a home survey
When you or a chartered surveyor inspect a property, you might decide it doesn’t currently have enough measures to counteract damp and condensation. While that’s important to note, it’s not necessarily a deal-breaker. Usually, taking certain steps – such as those mentioned in the previous section – can quickly eliminate the potential threat.
For an optional extra fee, chartered surveyors will include repair cost estimates on your home survey report. In a room suffering from damp, this could include:
- Extractor fan installation/replacement
- Plaster and plasterboard replacement
- Timber repairs (more serious if structural)
- Replacing damp-affected flooring, ceilings, appliances or furniture (if applicable)
- And more.
You could use this figure to negotiate a lower price. At GB Home Surveys, our teams of local RICS members are passionate about doing the best job for you. Before committing to buy a new home, instruct one of our associates to come out and have a look around. We offer the three standard levels of RICS home surveys: Valuation, Home Survey Level 2 and Home Survey Level 3.
You can expect to have our inspection report back with you within seven days (far above industry standard). We’ll let you know if we find signs of damp and condensation – and these are very common problems, so don’t be surprised if we do. You’re then welcome to chat with the surveyor and ask for their recommendations.
