Why Choose Our Loft Insulation Services in South Wales?

Why is your roof losing heat and increasing fuel bills?

Many homes in Monmouthshire suffer from inadequate roof insulation, which acts like leaving a window open during the winter months. If your loft lacks the recommended 270mm depth of insulation, you are likely wasting money on heating that simply drifts into the atmosphere. Beyond high energy costs, poor insulation leads to cold spots, uneven internal temperatures, and an increased risk of condensation and mould growth. Addressing this is the most cost-effective way to improve your home's EPC rating and create a warmer, healthier living environment.

Our PAS 2030 Accredited Installation Process

We pride ourselves on a professional, tidy, and compliant installation process that adheres to the strictest industry standards. As a PAS 2030 accredited contractor, we follow PAS 2035 retrofit standards to ensure your home is insulated effectively and safely. Our service includes a comprehensive initial assessment where we check for existing ventilation, electrical cabling, and structural integrity. Whether you require a simple top-up to meet current building regulations or a full removal of old, degraded materials that may be harbouring pests or moisture, our team manages the entire scope of work with minimal disruption.

Serving Abergavenny and Monmouthshire Property Types

Our expertise spans a wide range of building types found throughout Y Fenni and the surrounding Monmouthshire area. We are well-versed in the specific requirements for insulating everything from solid wall Victorian properties and charming bungalows to newer semi-detached homes and commercial buildings. We also have experience with non-traditional builds, ensuring that even properties with unique construction methods benefit from modern thermal performance. Our team is committed to providing solutions that balance historical preservation with modern energy-saving technology.

What Our Clients Say About Global Plastering

"Excellent work the team removing our old 1970's cladding and replacing it with insulation and a rendered finish. The job went smooth from start to finish with all old materials removed from site. We are very pleased with the end result and would thoroughly recommend Global Plastering."

A. Jenkins (Ferndale)

"Dilwyn and his team were brilliant and made a lovely job of our EWI. They were very friendly, hard-working, and left no mess at the end of each day. Our house looks great and we can definitely feel the benefits of the insulation already. I'm very glad we chose EWI especially with energy costs as they are now."

G. Toogood (Bristol)

"Charlotte and the team were professional, reliable, and excellent at communicating throughout. They did a fantastic job of skimming and rendering the back of our house during our renovation. Superb quality of work and highly recommended!"

Loft Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited loft insulation services. Discover how we eliminate draughts, reduce heat loss, and improve EPC ratings across South Wales and South West England, South Wales, and South West England.

How thick should my loft insulation be to save money?

+

To meet current UK building regulations and get the best results for your energy bills, we recommend a total thickness of 270mm. If you already have some insulation but it's thin or old, we can "top it up" to reach this standard, which makes a massive difference to heat loss reduction.

Can I still use my loft for storage after it is insulated?

+

Yes, but you shouldn't squash the insulation down with boxes, as this stops it from working. We can install loft legs or a raised boarding system. This allows the insulation to sit at the full 270mm depth while giving you a sturdy, flat platform for your belongings.

How long does it take to install?

+

For most standard homes, like a three-bedroom semi-detached in Ferndale, we can usually finish the job in just a few hours. It is one of the least invasive home improvements you can do, and we make sure all mess is cleared away before we leave.

Will loft insulation cause damp or condensation?

+

Only if it is installed poorly. We make sure that your roof eaves are kept clear so that air can still flow through the loft space. This is why professional installation is so important—we balance thermal comfort with proper ventilation to protect your roof timbers from rot.

Is there help available for the cost of insulation?

+

There are often various grants and schemes available, such as ECO4, particularly for low-income households or properties with low EPC ratings. As PAS 2030 accredited installers, we stay up to date with these schemes and can advise you on whether your project might qualify for funding.
