It was so nice to have professionals on site. Your whole company are first class and so lovely to deal with. Thank you, thank you, thank you. I have already sung your praises to friends who are looking to start projects themselves so hopefully they will be in touch. I’ll let you know when we are complete and hopefully you can come and share a glass of bubbles with us.

I selected Callidus Installations to provide bi-fold doors as part of a large refurbishment project in Brighton, based on a first hand recommendation from a friend who’d used them the previous year. Russell and his team were excellent in every respect. They supplied and fitted very good quality bi-fold doors at a competitive price. All the doors were manufactured according to my exact specification - topped off with a quick and professional installation.
