The Top Five: Condensation Prevention Tips

It’s that time of year again where it feels as though the ground will never be dry and we may never see blue sky again. As we crank up the heat indoors to compensate for the cold, damp outdoors, our homes might start to pay the price. Condensation affects lots of homes, particularly older ones which have been double glazed. If you notice water collecting on the inside of your windows, you spot mould on the windowsill, behind sofas, in corners, or in the bathroom, then you have a condensation problem. Don’t panic! It is fairly easy to deal with, with a few tweaks in your normal routine.

It’s that time of year again where it feels as though the ground will never be dry and we may never see blue sky again. As we crank up the heat indoors to compensate for the cold, damp outdoors, our homes might start to pay the price. Condensation affects lots of homes, particularly older ones which have been double glazed. If you notice water collecting on the inside of your windows, you spot mould on the windowsill, behind sofas, in corners, or in the bathroom, then you have a condensation problem. Don’t panic! It is fairly easy to deal with, with a few tweaks in your normal routine.

  1. Ventilation is the key to preventing condensation. Ideally, you want to keep air moving through your house, and opening windows is the perfect way to do this. However, this can be counterproductive. So, do what you can: shower with the door shut and the fan on, put your extractor fan on high when you cook, and put a lid on boiling pans to stop steam from escaping. Keep internal doors open to keep the air moving.
  2. Dehumidifiers come in all shapes and sizes and are relatively cheap. They literally remove water particles from the air and can be a godsend for homes plagued by condensation. Invest in a few small dehumidifier units and put them in the corners most affected.
  3. Slow and steady heating can help to reduce condensation. If you are trying to conserve fuel, you may be tempted to whack the heat on high for short periods of time, but this sudden temperature change can cause water vapour in the air to turn into water, which will lead to mould. Lower your thermostat and keep your heating on for longer; this will not only reduce condensation, but it is more efficient, too.
  4. Check the guttering and drainage. Why is it that so many home maintenance issues seem to come back to guttering?! If your guttering isn’t working properly, water could be sitting on the walls of the outside of your home. Cold, wet walls can create moisture when heated, which can lead to mould in addition to other potentially serious damp issues.
  5. Dry outside. If you have condensation issues, the last thing you want to do is bring in more water. Don’t be tempted to hang wet washing on the radiator, dry it outside or, if you must, use a (well ventilated) tumble dryer.

If you notice damp or mould, it could be part of a bigger problem. Get in touch with a damp specialist to diagnose the issue and get professional advice. For more useful information, follow us on Twitter or Facebook or, if you have a specific question, just Ask A Trader.

  • What home repairs should I never attempt myself?

    Gas work - full stop. Any work on gas appliances must be done by a Gas Safe registered engineer by law. Structural changes like removing walls, altering roof timbers, or touching anything load-bearing need professional assessment and often Building Regulations sign-off. Electrical work involving the consumer unit or new circuits must meet Part P. And if your property was built before 2000, be aware asbestos may be present - it can only be handled by a licensed specialist.

  • Which home improvements add the most value to a property?

    Improvements that add usable space or modernise the rooms buyers scrutinise most tend to deliver the strongest returns. Loft conversions consistently top the list - adding a bedroom and bathroom can add more value than the work costs in many areas. Kitchen and bathroom updates are next. Open-plan ground-floor extensions connecting to a kitchen-diner have become one of the most sought-after layouts in UK family homes. And energy improvements - insulation, a new boiler, solar panels - are increasingly influencing buyer decisions as running costs become a bigger part of the conversation.

  • Should I renovate my home or move house?

    There's no universal right answer - it depends on your situation. Moving gets you what you want without living through a building site, but stamp duty, estate agent fees, and moving costs can easily add up to tens of thousands of pounds. Renovating lets you stay put and invest in your own property, but comes with disruption and unexpected costs. The most useful comparison: get a clear view of what your home could realistically be worth after the work, and what a move would actually cost end to end. A local estate agent and a builder's quote can give you those two numbers.

  • What does a home survey actually cover and do I need one when buying?

    A survey is an independent assessment of a property's condition carried out by a qualified surveyor - separate from the mortgage valuation, which only tells the lender what the property is worth, not what's wrong with it. A HomeBuyer Report flags visible defects and anything that needs further investigation. A Full Building Survey goes deeper and is worth the extra cost on older, larger, or unusual properties. Given that a house is likely the biggest purchase you'll ever make, skipping the survey to save a few hundred pounds is a false economy - a single missed issue can cost far more to put right.

  • What should I do before starting any major home improvement project?

    Get your paperwork in order before anyone picks up a tool. Check whether you need planning permission or Building Regulations approval. Find out whether a Party Wall Agreement applies. Confirm your home insurance covers you during the works. Get at least three written quotes and make sure the scope of work is clearly agreed in writing with whoever you hire. And have a contingency budget - on almost any renovation, something unexpected comes up. The projects that go smoothly are usually the ones that were properly planned before they started.

  • What is the difference between freehold and leasehold and why does it matter for home improvements?

    If you own the freehold, you own the property and the land it sits on outright - you can generally do what you like subject to planning rules. If you own a leasehold property (common with flats), you own the right to live there for the remaining lease term, but the freeholder owns the building. This matters for home improvements because many leases require you to get the freeholder's written permission before making alterations - sometimes even internal ones. Always check your lease before starting any work, as doing alterations without the required consent can cause problems when you come to sell.
