How Our Floor Insulation Process Works

Our process begins with a comprehensive assessment of your property to ensure that underfloor insulation is the right solution for your specific building fabric. We work in compliance with PAS 2035 retrofit standards, carefully inspecting the void beneath your floor to check for ventilation requirements and structural health. Our skilled technicians then install high-performance insulation materials between the joists, effectively creating a continuous thermal barrier. This process eliminates cold air infiltration and prevents heat from escaping into the sub-floor area. By addressing these thermal bridges, we ensure your home retains heat far more effectively.

Why Choose Professional Floor Insulation for Your Home

Installing proper floor insulation is one of the most impactful ways to improve your home energy efficiency. By reducing heat loss, you will notice an immediate difference in the warmth of your floors, which in turn helps to lower your monthly heating costs. Beyond the financial savings, our insulation services play a vital role in moisture control, which is essential for preventing damp and mould growth in older buildings. Furthermore, if you are a landlord looking to improve the EPC rating of a rental property to meet MEES compliance, our retrofitting services provide a tangible way to upgrade your property value and regulatory status.

Underfloor Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited underfloor insulation, draught-proofing, and heat loss reduction services across South Wales and South West England and South Wales.

How much mess does the installation create?

+

If you have a crawl space under your home, we can often do the work without lifting your floorboards, meaning there is very little disruption to your home. If we do need to lift boards, our team works methodically to make sure the process is clean and tidy.

Will underfloor insulation cause my floors to rot?

+

No, provided it is installed correctly. We make sure that your sub-floor ventilation (air bricks) stays clear. This keeps the air moving and protects your timber joists from moisture build-up. This is why using a PAS 2030 accredited installer is so important.

How long does it take to pay for itself?

+

With energy prices remaining high, the "payback period" for floor insulation has shortened significantly. Most homeowners find that the savings on their heating bills cover the cost of the installation within a few years, all while enjoying a much more comfortable home.

Can you insulate solid concrete floors?

+

Yes, but the process is different. For solid floors, we usually lay high-density insulation boards on top of the concrete, followed by a new floor covering. This can raise the floor height slightly, so we will discuss the best options for your specific property during our site visit.
