From start to finish every one involved were professional and efficient . The sales man did not push the big “if you sign today” patter. The surveyor did his job quickly and efficiently explaining the process and the configuration of the windows . He took his time to explain the best fit . The workers arrived at 8.20 for an 8.30 start . ( Concerning the lock down they had permission to do the job as the flat was uninhabited ) . They worked tirelessly for 2 days ensuring the job was completed to a very high standard . I am a property developer and the job they did was above expectations.
