We asked Cliffside to replace our old conservatory including new foundation’s. We chose the solid roof option from Lela and had the interior plastered and the floor tiled, complete with under floor heating. All the staff a contractors were very professional and completed the works to a high standard. Communication with Cliffside was easy and any questions or issues we had were dealt with promptly.
We’re both absolutely delighted with our new room now being able to use it all year round. We would definitely recommend this company, thanks again Cliffside.
