Open windows to help condensation problems in winter - good or bad advice?

Issue #1: Condensation forms along the bottom or corners of the glass
Your window is trying to tell you: The house is not adequately ventilated, or there is a high moisture level in the home. This is less of a window problem and more of a moisture issue, but your window provides the telltale sign.

The moisture forms as condensation or frost on the windows when the temperature dips below freezing. This can lead to mold, mildew, or rotting wood sills. "It's the perfect environment for mold," says Bob Minoli, president of Integrity Residential Window Repair, near Sacramento, California. "Newer houses are built so tight that any moisture inside will stay there unless you do something to reduce it."

It's a balancing act to reduce the moisture level indoors without having the house too dry, but when you see condensation forming, you can run a dehumidifier, run bathroom fans, or open a single window for about 15 minutes a...

Condensation and mould

"The house is damp." This is perhaps the most common complaint landlords and agents receive. Have you got mould on your walls, ceilings or around your windows? If so, it is almost certainly your fault and you need to take action to prevent it. This is a long explanation, but could save you hundreds of pounds if you read, understand and act upon it.

Causes of damp

There are various sources of "damp" problems.

1. Water escaping from a water pipe, waste pipe, washing machine or the central heating system can cause damp patches to appear. Technically a leak rather than damp, these usually result in a very wet area close to (but not necessarily directly under) the source.

2. Missing roof slates, blocked gutters or blocked / damaged drain pipes can all cause rainwater to enter your home. Often insulation in the attic catches small roof leaks and tenants are not aware of a problem. However, any such fault that causes damage...

Windows with a cold sweat

Close-up of a hydrometer

A hygrometer monitors indoor relative humidity so you can track moisture changes.

Some homes have a problem with windows sweating on the inside during the winter, whenever the temperature drops to about 40 degrees F. Even the frames and the sills become wet. This even happens on newer homes that are well insulated. If you have this problem, the humidity level in your home is probably a bit too high. With double-pane windows, you should be able to sustain somewhere around 50 to 55 percent relative humidity indoors on a 40-degree night and not get condensation on your windows. That means that if the relative humidity in your home is higher, say 60 or 70 percent, your windows will become dehumidifiers and condense water from the air until the relative humidity level inside drops to the 55 percent range.

Newer homes are typically built much more tightly than older ones. This is good for many reasons, but...

If you’ve noticed condensation in your home for a while now, you might start to spot some mould.

It doesn’t matter whether you live in a listed building or a newly built apartment - condensation can have a big impact. It might have small beginnings, but if you don’t deal with condensation right away it can develop into greater and longer-lasting problems. These include damp and mould, which can damage your walls and furniture, and become health hazards to both you and your family.

In this guide you'll discover the causes of condensation, how to prevent it, and what to do to keep mould and damp at bay.

When does condensation occur?

Condensation occurs when warm air collides with cold surfaces, or when there’s too much humidity in your home. This is especially common in winter, when your central heating system comes on in the cooler hours of the mornings and evenings.

In addition to central heating, everyday activities like cooking,...

What Causes Window Condensation

Each winter I’m asked repeatedly why new energy efficient windows have condensation on them. I’ve written several articles about window condensation, Winter Window Condensation Problems, Window Condensation – Part II, and More On Winter Window Condensation, but I thought it was worth reviewing the issues because it seems to be so common today in newer homes.

Window condensation is due in large part because of how your home is built and not really a result of faulty windows. Each year homes are being built better with improved insulation, better vapor barriers and overall improved air infiltration. However this has resulted in very “tight” homes. “Tight” homes are great for helping us reduce how much energy it takes to heat and cool them however it makes it much harder to remove water laden air and contaminated air.

The number one reason you see condensation on your windows is...

Technology keeps getting better. Do our lives get better as a result? In certain specific ways, maybe yes, but in general, I would say, not really. How is that possible? I think there are two big things at work. Technology is evolving semi-independently of the humans that produce it. We don’t control the evolution of our tools any more than we control the evolution of our gut fauna or infectious diseases. Also, the pace of technological change is a lot faster than the pace of our genetic evolution. Our brain anatomy is having a hard time keeping pace with the changes in the world that we’re making inadvertently with our tools.

The Stone Age was long, modernity is short

There have been anatomically modern humans for a million years at least. For nearly all of that time, we didn’t make much progress on the technology front. Only in the past forty or fifty thousand years has there been the fast technological change that brought us to our present state. Jared...

Thanks to the computer technology, which is constantly changing, we are able to access more information quicker and in a shorter time. For instance in today's society the fields of Communication and Medicine is constantly advancing, but yet they both create significant losses. .
Technology has helped increase the speed of communication and decrease its cost. However, at the same time it has caused people to become more impersonal with each other. In earlier times the major form of communication was for people to visit each other and go to public meeting places. One of the next major advances was the telephone. Due to the telephone people no longer went to the public meeting places as often as they used to. As time goes on, new advances still allow people to contact and communicate with each other more easily. These advances such as faxes, cell phones and electronic mail, although seemingly making life easier, each help to decrease the earlier forms of...

As I write this the temperature in Guildford is dropping down to -5°C or worse and the skies are clear and blue. When I touch my car there is a spark of blue as a static shock is generated and condensation forms at the bottom of the windows overnight as surface temperature of the glass drops with the overnight chill.

A beautiful view and opening the window will clear any condensation. But do you really want to let the cold air in?

So what is the best way to deal with this condensation, open the windows or use a dehumidifier? Now you would expect me to say buy a dehumidifier because I am a dehumidifier manufacturer, so let’s look at the merits of the other course of action and open the windows.

When people talk about condensation or mould problems the advice will often be to open the window and in older properties where ventilation is not so much a choice but something that happens whether you like it or not condensation is rarely an issue. So why does...

Hi I'm a new poster here, but I happened to notice this thread and feel the need to reply.

We have double glazing of 2 types, three windows of the old (real-looking UPVC, but made of metal and covered in white stuff) double glazing, and the rest of the house is new style white plastic UPVC. We get condensation on all windows in autumn/winter/spring (i'm looking it now as I type). We are soon to be changing the older windows to new UPVC ones which should help, as condensation literally runs off these windows at the moment. But I wonder if our 'newer' windows need changed too because I am at a loss as to why we have such a condensation problem.

We don't create any more moisture than you're average household (theres 2 of us), we dry clothes outside as much as possible, we open windows often, we have central heating which we run in the morning and evening, we have a fan in kitchen and bathroom. Our house is airy and doesn't have dampness.

Any ideas...

I live in North Myrtle Beach SC, 1 Ѕ block from the beach. Ever since we have moved into our condo Nov. 2009, we had high humidity in our condo. When the temperature drops below 40 degrees we have very heavy condensation on the windows in the front of Condo and the sliding doors in the back of the condo. We do have a dehumidifier that we run especially during the cooler season. We live on the second floor in the very middle condo on that floor. Other words there are four flours, five condos across on each floor. If you were facing the condo there is a fire wall on the right of us. Ok we have checked with every owner in this condo and we are the only ones that have this problem. The humidity continues to run high all year. The building is made of cement and steel structure. Can anyone tell us what we can do or what type of company to call and get this resolved? They have run test in our condo and it does come back we are having a moisture problem. Any questions please ask, we will...
