pvcu windows
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.

We needed a specialist product which Callidus Installations sourced and fitted for us with an exceptional level of customer service. I would definitely recommend Trend Aluminium to others, thank you for the effort you put in to make sure everything was finished properly and to a high standard.

We love the doors, they look fantastic and we are really pleased with our choice and the work done. Many thanks to the team for coming out to install on a Saturday.

Callidus Installations did a fantastic job in fitting my replacement windows. They were extremely flexible and able to complete the work to a high standard in a short timeframe. They were a pleasure to deal with from start to finish.

Buying replacement windows is a big investment and it is difficult to know what to look for. We have a Victorian property so were going from old wooden sash windows to PVCu replacements. We wanted to retain the period look and feel but increase the heat efficiency from the property.

From the first time I spoke to Russell and John at Callidus Installations they gave me a huge amount of confidence with their knowledge of PVCu sash windows, what to look out for, and how they are installed, including two consultations.
