Insulation & Damp Problems Solved Properly in Oldham
Based in Manchester, we carry out the majority of our work across Greater Manchester and the North West.
Our Cavity Wall Insulation & Loft Insulation Services
Not sure what’s causing the damp? Before any treatment is recommended, the cause needs to be properly identified. We carry out independent damp surveys using specialist equipment, giving you clear findings and recommendations you can trust.
Failed or saturated cavity wall insulation is a common cause of damp in UK homes. We use our own purpose-built vacuum extraction system to remove old insulation safely and thoroughly, identifying the underlying issue so the problem doesn’t return.
Once the cavity is clear and suitable, we install EvoBead EPS bead insulation: moisture-resistant, thermally efficient, and backed by a 25-year product guarantee. As KIWA approved installers, every job is carried out to the highest possible standard.
Old, damaged, or contaminated loft insulation can cause more problems than it solves. Whether it’s rodent damage, water ingress, or material that has simply compressed over time, we remove all types safely and leave the space clean and ready.
After removal, or where existing insulation has deteriorated, we install fresh loft insulation to current Building Regulations standards. A well-insulated loft makes a real difference to heating costs and year-round comfort throughout your home.
Want to make better use of your loft space? We fit raised boarding systems that sit neatly above your insulation, giving you practical, accessible storage without compromising thermal performance or squashing the layer beneath. A simple, smart upgrade.
Could Your Cavity Wall Insulation Be Causing Damp in Oldham?
Cavity wall insulation doesn’t always fail immediately. In many properties, problems build up gradually over years, and by the time damp appears on an internal wall, moisture may already have been sitting in the cavity for some time.
It is worth checking whether your property could be at risk. Problems are more likely where:
- The property is in a medium to high exposure zone for wind-driven rain
- Cavity wall insulation was installed in an unsuitable property type or location
- The insulation material was not appropriate for the wall construction
- There are gaps around pipework, vents, or flues allowing moisture into the cavity
- Pointing or render is in poor condition
- Debris at the base of the cavity is causing moisture to bridge across to the inner wall
This is a view from the outside of a house with damp cavity wall insulation. The insulation itself is soaking wet. This will cause damp and mould issues inside the walls and needs to be removed.
This is the inside of a property that had damp cavity wall insulation. As you can see over time, it has bridged through to the inner brick of the house and damaged all the plaster work. It had to be removed.
Another cavity wall that has damp insulation. Over time, this insulation has become soaking wet, and will cause issues for the internal walls such as mould and damp. It needed to be removed.
Debris at the base of the cavity may lead to bridging and damp problems. Professional cavity wall insulation extraction removes this debris, helping to prevent bridging and eliminate the risk of damp.
This video shows a house with wet cavity wall insulation. This excessive moisture will in turn cause issues with damp and mould on internal walls. It needed professional cavity wall insulation extraction.

FAQs
Do I actually need cavity wall insulation removal?
Not always. In some cases, damp is caused by ventilation issues, pointing, or other factors. That’s why we start with a proper survey, so you only pay for the work that’s genuinely needed.
What are the signs of failed cavity wall insulation?
Common signs include damp patches on internal walls, mould, cold spots, and a musty smell. These issues often build up gradually over time.
Do you carry out assessments before recommending any work?
Yes. Every recommendation is based on a proper damp and insulation survey and/or assessment. We do not carry out removal or installation work without first identifying the cause and ensuring that your property is suitable for extraction and/or installation.
Will my home need to be re-insulated after cavity wall extraction?
In many cases, yes, but only once the underlying issue has been resolved and the cavity is suitable. We will advise you based on the condition of your property.
How long does the work take?
Most cavity wall extraction or installation jobs are completed within one to two days, depending on the size of the property and the type of work required.
