Pebbledash semis
Cold walls with no cavity to fill, or a finish that’s cracking. Insulated from the outside and rendered, like the semi above.
External wall insulationHome / Areas We Cover / Ilkeston
Just over the Derbyshire border, where we’ve insulated and re-rendered homes.
Ilkeston
Ilkeston is about eight miles west of our base, just into Derbyshire. We’ve insulated and re-rendered houses here, like the pebbledash semi in the photo, and we cover Cotmanhay, Kirk Hallam and Heanor as well.
Ilkeston has a lot of Victorian terraces near the centre and big post-war estates around Cotmanhay and Kirk Hallam. Many of those post-war semis have pebbledash walls that are cold inside and tired outside.

“Very impressed from start to finish. No hard sell, got a quote and was left to us to decide. We decided to have the conservatory roof insulated on the inside. Looks amazing. The fitters arrived early and straight onto the job, and left everything clean and tidy!”
“The team turned up early and immediately started to set up. They completed the task in just over 4 hours, cleaned up and moved the heavy furniture back into place. Sales Manager and the Owner then turned up later in the day to check if we were happy before we had to pay. A good experience from start to finish.”
“Excellent service from start to finish. Gareth the sales person explained the process and was not too pushy. The process that was explained was followed by the fitters who were really good and friendly, we could not fault them.”
“Great job done boarding our loft by a polite and tidy team. Happy to recommend.”
“Fantastic service from sales to installation. Great product. Highly recommend the whole experience. Many thanks Cozy Top Team”
“Really happy with Cozy Top. Great people with excellent workmanship and materials.”
“Following a visit by the Director of Cozy Top Home, to discuss the best options for my conservatory roof. I placed the order, the Surveyor visited and he explained in full detail how the work would be carried out. The two fitters turned up at the time advised, and worked non stop, they did an excellent job, and tidied up after them. I am extremely pleased with the service provided, and would recommend them.”
“The entire team is brilliant. Gareth came in and provided a free quote, clearly explaining the entire process. David and Mark arrived early in the morning and completed the work within just 4 hours. The work was carried out very professionally and meticulously.”
“We started with the Estimator/Sales Gareth who was very helpful, friendly and discussed how the work would be done. The work was carried out with 2 brothers who had a good work ethic, got on with the job with precision and cleanliness. On completion we had a visit from the company work inspector to check we were happy with the work done.”

Often not, but it depends on the house and the street. Erewash Borough Council decides, and we check at the survey.
You choose the colour and finish before we start. If you want it to sit well next to the house next door, we will help you pick.
