FREQUENTLY ASKED QUESTIONS
How can I know if my insulation has a problem?
There are specific indicators you can look out for to know if your cavity wall insulation may be ineffective and damaged. For example, if your energy bills are unusually high, higher than expected, or there are cold spots and damp areas around the wall. These can all be indicators.
What issues do damp walls lead to?
If your insulation and walls become damp, your thermal resistance will significantly weaken. Your insulation will become ineffective, and you will start to see your energy bills increase and your rooms colder throughout winter.
How much can I save with effective cavity wall insulation?
Walls lose the most heat out of all property or home areas. Therefore, they need to be very well-insulated for you to start saving money on heating bills and reduce your co2 emissions. A well-insulated cavity wall means you can reduce heat loss by up to 35%, so ensuring your insulation is still effective is essential.
What can happen to my property with the wrong cavity wall insulation?
If your cavity wall was installed with the incorrect or low-quality insulation material, it could slump and weaken the structure. Your thermal resistance will be ineffective, the wall will be cold, and condensation and mould may form. Decorative surfaces can start to peel, stain and flake off. Your property also may begin to smell as the dampness spreads, creating a perfect breeding ground for black mould, eventually deteriorating your structure and weakening the building.
What types of properties can benefit from cavity wall insulation?
You can benefit from cavity wall insulation if your exterior walls have a cavity more significant than 50mm, creating a perfect area to be insulated. Depending on the property’s location, specific insulation may need to be issued to best combat the climate and surrounding conditions.
Cavity Wall Extraction
What Is Cavity Wall Insulation?
Most homes built since the 1920s have cavity walls, i.e. an inner and an outer ‘skin’ with a gap between them. Filling this gap with insulation material improved heat retention inside the property.
Methods to insulate your cavity walls:
Whitewool cavity wall insulation is a mineral fibre
Expanded Polystyrene Beads (EPS) is a high-performance, injected, blown grey bead
Polystyrene beads are entirely waterproof, so even if they get wet, they will dry out without any lasting damage or adverse effect on your insulation.
Is My Property Suitable for Cavity Wall Insulation?
If your property was built after the 1920s, you almost certainly have cavity walls. Older houses are more likely to have solid walls.
Your home will usually be suitable for cavity wall insulation if it meets these criteria:
Its external walls are unfilled cavity walls.
Your cavity is at least 50mm wide.
The masonry or brickwork of your property is in good condition.
It is more than ten years old (most newer houses will have insulation already).
The walls are not exposed to driving rain.
How Cavity Wall Insulation Is Installed?
You’ll need a registered installer to fit cavity wall insulation – it’s not a job you can do yourself.
The insulation material is injected through small holes drilled in the exterior brickwork. Once the installation is complete, we make all brickwork, blending in the installation work to retain the look of your property.
Cavity walls are filled with an insulating material; commonly-used materials include mineral wool, polystyrene beads or foam. Insulating cavity walls will help trap heat and prevent warmth from escaping.
A typical installation usually takes less than half a day.
Why Should you Remove your Cavity Wall Insulation?
Whether you have just moved into your property or have been living there a while, it may be a good idea to assess the effectiveness of the insulation in your cavity walls. Depending on the age of your building, where it is located, what insulation was used and many other factors, you may be in need of extracting the insulation from your walls.
How Much Does Cavity Wall Insulation Cost?
The average cost of cavity wall insulation can take time to determine.
We price each job individually, as the scope of the required work can vary, especially as we take on jobs of any size
What does damp proofing mean?
Damp proofing is simply the generic term used to describe the various forms of damp treatment that can address problems caused by conditions like rising damp, penetrating damp or excessive condensation.
In common usage, though, damp proofing generally refers to installing a remedial course through the damp-proof injection method.
What is a damp-proof course?
When people refer to damp-proofing, they generally talk about measures to keep groundwater out of the building. At the same time, waterproofing describes treatments that prevent any water from entering a property.
A helpful guideline when considering the differences between damp-proofing and waterproofing is to remember that damp proofing is typically used to prevent damp problems above the ground. In contrast, waterproofing is generally employed to solve dampness and flooding problems below ground.

Can I remortgage with spray foam insulation?

Why do lenders have a problem with Spray Foam in properties?
When a roof space has been sealed using spray foam insulation, it restricts air circulation. This can negatively impact roof timbers and, therefore, the integrity of a roof. When condensation accumulates in a roof space, woods start to rot.
