Why choose professional insulation for your property?

A significant amount of heat escapes through an uninsulated roof, making it the most impactful area for energy-saving upgrades. By installing high-performance insulation, you tackle thermal bridging directly, preventing cold spots and reducing the risk of condensation and black mould. Our services are designed to improve your home energy efficiency significantly, helping you achieve a better EPC rating. This is particularly vital for landlords in Blackwood and surrounding areas who must ensure their rental properties meet current MEES compliance standards.

We pride ourselves on our technical expertise and rigorous standards. As a PAS 2030 compliant and PAS 2035 accredited contractor, we provide professional retrofit coordination that guarantees your project is handled with precision. Our team understands the specific requirements of the local housing stock, from solid wall Victorian properties to non-traditional builds. We work closely with our sister company, Global Plastering, to provide a seamless end-to-end service, ensuring all internal finishing is completed to a professional standard after our insulation work is installed.

How our local installation process works

The process begins with a comprehensive, no-obligation survey of your property in Y Coed Duon or Blackwood. Our experts assess your roof structure, ventilation needs, and existing insulation levels to recommend the most effective solution. Once the plan is agreed upon, our CHAS-accredited team carries out the installation with minimal disruption.

Roof & Loft Insulation FAQs

Frequently Asked Questions

Answers to common questions about eliminating thermal bridging, reducing heat loss, improving your EPC rating, and our PAS 2030 accredited roof insulation services in South Wales and South West England and across South Wales.

How much money can I save with new loft insulation?

+

Most homeowners in South Wales see a significant drop in their heating bills, often between £200 and £400 a year depending on the size of the house. Because the material lasts for decades, the upgrade usually pays for itself very quickly.

Will I lose my loft storage space if I add more insulation?

+

Not necessarily. While we need to reach a certain depth to meet building regulations, we can use loft legs or raised flooring systems. This allows the insulation to breathe while still giving you a solid platform for storage.

Does roof insulation help with damp and mould?

+

Yes, it does. By keeping the ceiling warmer, you reduce the chance of water vapour condensing on the surface. This is one of the best ways to stop black mould from growing in the corners of your bedrooms.

How long does the installation take?

+

For most standard homes in the Rhondda or Cardiff area, we can complete a loft insulation upgrade in just a few hours. It is a very non-disruptive way to improve your home’s energy efficiency.
