Joan, Surrey02/01/2019
Very happy with the work completed
Customer Service
The whole experience was excellent from the first time we had a meeting with the company owner to the finish. We were constantly kept informed on anything to do with the build. Darren (the owner) came to the site every day to ensure that the work was completed to his high standards. Each tradesman involved was on time and worked very hard and left no mess at all. We are very pleased with the result and cannot recommend Astral Windows enough.
