Book your retrofit assessment

Why is your home losing heat through the floor?

A large portion of heat can escape through your ground floor, particularly in homes with suspended timber joists. This creates an uncomfortable environment and forces your heating system to work much harder than necessary. By sealing these gaps and installing high-performance insulation, we can effectively stop draughts and thermal bridging. This upgrade is a crucial step for improving your property's overall EPC rating, especially for those looking to meet modern energy efficiency standards or comply with MEES regulations for rental properties.

Our technical approach to floor insulation

Our team works to the highest industry standards, ensuring full compliance with PAS 2030 and PAS 2035 retrofit guidelines. We begin with a thorough assessment of your property to determine the most effective insulation method for your specific floor structure. Whether you have traditional suspended timber floors or specific solid floor requirements, our installation process is designed to be unobtrusive and highly efficient. We use modern, safe, and sustainable materials to ensure long-term thermal retention and moisture control.

Full service support from our local team

What sets us apart is our end-to-end approach to home improvement. As part of a partnership with our sister company, Global Plastering, we provide a seamless service that includes any necessary finishing work, ensuring your property is left in pristine condition.

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.
