Why is your floor making your home cold?

Many properties in Llandeilo suffer from significant thermal bridging and heat loss through the floorboards. In older Victorian or traditional stone-built houses, cold air often circulates freely beneath suspended timber floors, turning your living space into a chilly environment during the winter months. This is a primary driver of high energy bills and condensation problems. By installing professional underfloor insulation, we create a thermal barrier that stops these drafts at the source. This process does not just improve the internal temperature; it helps mitigate damp and mould issues, protecting the structural integrity of your home while creating a much cosier atmosphere for your family.

The Installation Process for Your Property

Our process begins with a thorough thermal assessment of your floor structure. For suspended timber floors, we typically access the space from below or, where necessary, through carefully managed lifting of boards. We install high-performance insulation materials between the joists, ensuring a snug fit that prevents thermal bypassing. If you have a concrete substrate, we provide expert advice on the most effective rigid insulation boards to suit your floor build-up. We ensure all work adheres to current building regulations and PAS 2035 guidelines. As part of our commitment to a full service, we work closely with our sister company, Global Plastering, who can handle any necessary reinstatement or internal finishing work once the insulation is in place.

Benefits of Professional Draught Proofing and Insulation

Investing in high-quality underfloor insulation offers immediate and long-term rewards for homeowners in Carmarthenshire. Beyond the obvious reduction in your monthly heating bills, you will notice a significant improvement in the ambient warmth of your rooms. For landlords managing rental stock, this is a highly effective way to improve an EPC rating and meet mandatory MEES compliance standards.

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.
