Really impressed with the job that has been done by the team at Kaislar Ltd. They were always practical where possible and took account of my parents sensitivities. We now have a huge room with balcony, black heritage type doors and windows that are amazing. Room with ensuite. It was not a small job, but they were very competitive on price and super professional. Perfectly completed as per agreed schedule.

I am thoroughly impressed with the rear extension Kaislar completed on our home. Their team demonstrated exceptional professionalism and expertise throughout the entire process.
From the initial design consultation to the final implementation, they exhibited meticulous attention to detail and a commitment to quality craftsmanship.

Their communication was excellent; we were kept well-informed at every stage. The project was completed on schedule and within the agreed budget, which I found most satisfactory.

I wholeheartedly recommend Kaislar for any home extension project. Their blend of technical skill, creative design and customer service is commendable.

We were recommended Kaislar and his team by a friend and I recently had the pleasure of liasing with them on a renovation project, and I couldn't be more satisfied with their outstanding work and materials. They transformed by outdated place into a sleek, modern space that perfectly matched the samples we provided.
