Why choose professional insulation for your Penarth home?

Many older properties in Penarth and the wider Vale of Glamorgan suffer from significant thermal bridging and heat loss through suspended timber floors. Without proper insulation, the air beneath your home acts as a heat sink, pulling warmth directly through your floorboards. Our PAS 2030 accredited team specialises in rectifying this issue, ensuring your home meets modern thermal efficiency standards. Whether you are looking to improve your EPC rating to meet current MEES regulations or simply want to stop the cold from creeping into your living room, we provide the technical expertise required to deliver a long-lasting, effective solution.

How our PAS 2035 retrofit process works

We take a whole-house approach to energy efficiency, ensuring that any work we carry out adheres to strict PAS 2035 guidelines. The process begins with a professional survey of your property in Penarth, Cardiff, or the surrounding Vale of Glamorgan area. Our qualified retrofit assessors will identify the specific construction type of your floor, whether it is a traditional suspended timber frame or a solid concrete slab. We then design a tailored insulation strategy that addresses ventilation and moisture control, ensuring your property remains healthy and breathable while achieving superior thermal performance. By managing the full compliance and installation process, we take the stress out of your home improvement project.

Benefits of high-quality floor insulation

Investing in underfloor insulation offers immediate and long-term benefits for your property. You will notice a significant reduction in heating costs as your boiler no longer has to work overtime to counteract the heat lost through the ground. Beyond energy savings, our solutions help prevent damp and condensation issues by regulating floor temperatures more effectively. For rental properties, this is a vital step in reaching the required EPC rating for compliance. When you choose us, you benefit from our SWIGA-backed guarantees and our CHAS accreditation, giving you complete peace of mind that your home is in safe, professional hands.

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.
