wall cavity removal and new
Posted 12 March
The entire experience, from speaking with the receptionist to the arrival of the technicians, was exceptionally professional. Everyone was very polite, arrived punctually, and completed the job within the scheduled timeframe. They also ensured everything was tidy afterward. I would highly recommend their services. We had our old wall cavity removed and a new one installed. Thank you.

Professional from start to finish, excellent service and communication both on email and face to face. We had Cavity Wall filled in our 1960 dormer bungalow, the team who came out were knowledgable, friendly, tidy and efficient. They went above and beyond our expectations. Price was competitive and I would have no doubt in recommencing. Thank you, we noticed a huge difference in the warmth of our home this winter.

Welcome to our Checkatrade page and thank you for taking the time to look into our details.

We are a small company based in South Yorkshire offering superior bonded poly bead cavity wall insulation.

We offer cavity wall insulation for many purposes and more often than not we can provide a solution for non-standard jobs where others cannot cater for.

We specialise in installing brick and stone properties.

Our compressed air system of bonded polybead is injected under pressure to ensure a tightly compacted fill within the cavity.

Our main aspects of work are:

Stone wall insulation - 'Virtually No Drill System' - We can fill walls without showing any drill holes - (contact us for more details).
New build cavity insulation - Insulated internally before plastering.
Narrow cavity wall insulation (Brick or stone)
Partial fill cavity wall insulation (poly blocks on inner wall still leaving a cavity)
Cavity wall insulation extraction (removes faulty or problematic insulation)
Difficult access jobs (conservatories, river sides or multi-storey)
Cavity wall insulation extraction - Removal of problematic insulation
(www.multi-therm.co.uk) Cavity can be left empty or re-insulated properly.

For any queries or questions please call us today or email us

We look forward to working with you in the future !
