Flood damage

Why do we live in houses? This may seem like a silly question but actually the fundamental reason we live in buildings is to shelter us from the outside world, and in particular the elements. Sometimes our homes do not work – they ‘break down’ and cease to protect us, as people who have been flooded recently know only too well. When this happens we need to not only get our homes working again – providing the warmth and comfort we expect – but also to avoid problems in the future, as far as possible.

Our new Flood Damage page is open from today at and highlights a key issue that is often overlooked: what do we do about the insulation in our walls? Our advice to householders affected by flooding is:

  1. It is very important to replace the insulation that is in the walls, particularly if it is of the mineral fibre type. Without insulation your home will not feel as warm and cosy as it once did.
  2. When you come to replace the insulation, it is very important to choose a professional contractor who has the specialist equipment and skills to remove insulation properly, and then to replace it with a bead material that is much less likely to be damaged by any flooding that might occur in the future.


Householders will be making claims to their insurance company and will need to include replacement of wall insulation in the claim. It is an expensive job – if done properly. It is important to check that your insurance company knows about the problem and understands what needs to be done to put it right. For example, it would be unwise to replace mineral fibre insulation with the same material: when this becomes soaking wet it ceases to function and must be removed. It is sensible to replace with bead materials because these will dry out naturally as the wall dries out. Let’s hope you are never flooded again – but if you are you probably won’t need to replace the insulation again.

Our complete professional service includes extraction of wall insulation using special machines designed for this specific purpose – part of one of these machines is shown in the picture, left. These ensure that the maximum possible amount of insulation is removed, and take two men about one day to complete, with two machines and a roadside compressor. We then refill the walls with bead material, which takes about 2 to 3 hours. We will be happy to provide you with a quote for the work which you can pass on to your insurance company. You might want to apply online on our Flood Damage page or telephone our Sheffield or Devon offices, whichever is closer to you.

It would help to keep costs down if a number of houses in the same street or village are treated at the same time, so it might be worth talking to your neighbours.

When we finish the work you will be provided with a new 25-year guarantee, which covers faulty materials or workmanship.
