Frequently Asked Questions

Our team is just a click away if you need any advice about your cavity walls, but here are some answers to the questions our customers ask most.

  • Why does my cavity wall insulation need to be removed?
    Cavity wall insulation is a popular way for people to improve the energy efficiency of their homes and save money on their energy bills. However, not all companies are up to the job and those who don’t comply with best practice leave property owners with a whole host of problems caused by poorly installed cavity wall insulation.

    Not every property can have cavity wall insulation, but a less than scrupulous company or one without the proper training will ignore this or may do a poor quality job. For instance, steel frame houses should never have cavity wall insulation installed, so this could be one reason why your insulation needs to be removed.

    If your property has been flooded, this can damage the insulation, causing ongoing problems. There may also be rubble in the cavity, which is causing damp and compromising the insulation. Fortunately, our free inspection will identify any of these issues and our team will explain everything with a visual of the cavity wall.

    The good news is that we can remove cavity wall insulation if it’s causing problems.
  • What sort of problems are signs of failed cavity wall insulation?
    Sometimes cavity wall insulation is badly installed, degrades over time or your property may not be suitable, which can lead to issues. Left unchecked, failed cavity wall insulation can lead to damp and mould, which can have serious implications for the structure of the property, impacting on its value.

    If you have any of the following problems in your property, it could be caused by cavity wall insulation:

    • Cold spots on walls, caused by areas where the cavity wall is not correctly insulated
    • Trouble with excess condensation, causing damp problems inside the property
    • Black mould on the walls caused by the damp
    • Peeling wallpaper and bubbling paint from wet walls
  • How do you remove cavity wall insulation?
    The problems caused by failed cavity wall insulation can be stressful for homeowners, but with fast action, it is possible to remove cavity wall insulation and restore the property to its previous state. Complete Remedial Solutions is fully accredited to carry out the removal to the highest standards using the latest technology.

    We take great care to ensure the cavity wall insulation removal is as clean and effective as possible, leaving your home looking better than ever. We start by carefully removing bricks from the bottom of the wall. Compressed air is blown into the cavity and then we use an industrial vacuum to extract all the damaged insulation and any debris through the gap. All the brickwork is replaced to ensure nobody can see we were ever there, except that your home is warm and dry again.
  • Can you reinstall cavity wall insulation after it’s been removed?
    The Complete Remedial Solutions team has over 50 years' industry experience working for the leading insulation companies. We can also reassess your property's suitability to reinstall it if possible.
  • How do I know the work won’t cause more damage?
    Complete Remedial Solutions are experts in solving the problems caused by failed cavity wall insulation.

Our aim is to help people and property owners reduce heating demand and make their homes healthier.
