  • Have to say how impressed we were with Mark, Lee & Joe. As we’re all our neighbours! They have commented about how polite you all are. No phones going off or checking them all the time. No loud music blaring and no swearing, it was all very impressive, the attention to tidiness every evening was much appreciated too.

  • Mark has just completed our new cloakroom installation and we are very pleased with the result. He and his team always work to ensure a high quality finish and each of his team are always focused on the end result. They care about how it will all look and make helpful and valued suggestions throughout rather than just doing the minimum. Great people, great attitude and great job.

I would without doubt recommend Windsor Installations.

    John Noonan
  • Mark and his team have recently completed my kitchen refurbishment. This was the second time I have used Windsor Installations, the first was a bathroom refurb. I have nothing but praise for all aspects of their work including their interaction with you as a customer. Mark will give an honest quote and his team will often complete little extras to correct any issues they find as they go or to improve the design. In the case of my bathroom, which is a small area. Mark changed the design to save me money on a smaller washbasin and the refitted the original basin in a better position. I would strongly recommend Windsor Installations to anyone looking to improve their home.
