Very professional and high quality workmanship.Eddie and team completed external silicone render to our front gable. Eddie takes great pride in his work. He masked adjacent decorative brickwork and eaves to ensure they were fully protected. Thank you Eddie for an outstanding job.

When we stared looking at rendering Ed came over and spent time explaining various options that we could take. They did a great job insulating and rendering our house and kept our property very tidy during the process. We are very happy with how it now looks and hope that our home will be much warmer this coming winter.

I contacted Erdal of EZ through recommendations, he came and spoke through my choice of options between Weber and K Rend, showed good product understanding and experience. We agreed on the Weber, set a date and gave quote. Works completed to a very high standard, very tidy and precise and showed a passion for his workmanship and delivery. Photos show the standard, very pleased and satisfied with the work. Polite and respectful to the family In my absence also. Highly recommend.
