Failed cavity wall insulation is the leading cause of penetrating damp in UK homes. First Choice Energy are specialist extractors serving South Wales and South West England, free survey, honest advice, no obligation.
Failed cavity wall insulation does not fix itself. Left untreated, these problems get worse and the repair costs grow.
Dark, wet patches appearing on internal walls, especially after rain, are a classic sign of failed insulation allowing water to bridge the cavity.
Mould on walls and window reveals is not just unsightly, it causes respiratory problems. Persistent indoor mould is often a sign of moisture trapped in the cavity.
Wet insulation performs far worse than dry insulation. If your heating bills have risen despite no obvious cause, compromised cavity insulation could be responsible.
Bubbling or cracking on internal plaster, or cracks appearing in external render, can indicate water movement caused by saturated insulation in the cavity.
If your walls were insulated years ago but feel no warmer now, the insulation may have slumped, degraded, or become saturated, and needs removing.
Older mineral wool and polystyrene bead installations have a limited lifespan. Even if yours shows no visible symptoms, a free survey can confirm its current condition.
The entire process is carried out by our specialist team. Minimal disruption, no mess left behind.
We assess your property using a borescope camera to inspect the cavity condition before any work is agreed. No charge, no obligation.
Small suction holes are drilled discreetly around the base of your external walls. Compressed air loosens the insulation and an industrial vacuum removes it.
After extraction, a borescope inspection confirms the cavity is completely clear. We photograph throughout so you have a full record of the work.
Drill holes are filled and made good. Airbricks are fitted to ensure proper cavity ventilation going forward. You would never know we were there.
Our team filmed a real cavity wall extraction from start to finish. This is exactly what happens at your property, no surprises, no hidden steps.
"Steve and Aaron were absolutely fantastic from start to finish. Very professional and we were over the moon with the job they did. Highly recommended."
"My elderly parents' home had been covered with damp and mould for two years. First Choice Energy were the only company not to try to overcharge them. The insulation was removed within 2 weeks. The damp and mould is now clearing up."
"Really good job removing old cavity wall insulation from my property. Quick to respond. The damp problems have already improved massively. The team went the extra mile and even cleaned up the windows and doors."
We assess your property, give you a clear quote, and explain your options honestly. If extraction is not right for your home, we will tell you that too.
