What’s Involved in Blown Bead And Loft Roll Sewards End Services?

Blown bead cavity insulation fills the gap between your property’s inner and outer walls with lightweight polystyrene beads, creating an effective thermal barrier that reduces heat loss and cuts energy costs. It’s suitable for most cavity wall constructions and can be installed quickly with minimal disruption.

Loft roll insulation involves laying mineral wool or glass fibre rolls between and over the joists in your loft space, trapping warm air inside your home and preventing it from escaping through the roof. We can supply and install high-quality insulation materials to meet current building regulations and improve your property’s energy efficiency.

Both solutions deliver excellent thermal performance, reduce condensation risk, and create a more comfortable living environment throughout the year.

 Trustindex verifies that the original source of the review is Google. I did screed with them twice, we had our house done in 2 phases and in the 1st phase they supplied us with specific stats, on the 2nd phase they supplied us with different stats model and a control box which allows to connect to them remotely but, then I had an issue with the phase 1 stats won't connect to the system as they don't support that functionality. I rang their customer support and explained the issue, they offered to swap the phase 1 stats with new ones so, all stats will be from the same model and all will connect to the control box.
One more word about their expertise, the 2 phases were done a part so the 1st phase screed was higher than the existing old bit, when they came to do the old bit on the 2nd phase, I asked if they can do the screed so that both bits will be same height, they did it perfectly, both phases met up level and the wood floor on top is at the same height, I must say I was sceptic but, these guys are awesome, they are experts in what they do. that made me so happy!
That is a company who cares about their business and about their customers.
I will definitely recommend and will definitely do business with them again.
Thanks you Co-Dunkell

We had our screed pumped in and laid by the team at Co-Dunkall today at our self-build, the three man team onsite and those in the office were all professional and friendly at all stages from quotation, survey and the final delivery and instation. Everyone has done what they said they would do and within the timescale given. If you need pumped floor screed I can recomend this company 100%

 Trustindex verifies that the original source of the review is Google. We had Co-dunkall provide a cemfloor screed for an outbuilding which needed the floor raising. Thoroughly professional service 3 survey calls and inspections prior to the job. Nikki and the office team all highly knowledgable on so many aspects and on the day they even provided a 6 wheel mini mix to accommodate the property complexities. Good follow up and so pleased for a  very clean and tidy washout considering how messy the job can be. You would not know they had been on site. End result is exactly what we needed
