"I was pleased with the work carried out by the engineer and it just took him a few minutes to figure out what was wrong."
"The engineer,Shermin, has been very good indeed. He has been very efficient and skilled in carrying out the subsequent servicing and repair work "
"The engineer Shermin was extremely helpful and followed through with all that he said would happen at the time expected. Great Service! "
WOW!! so impressed, I have been tirelessly trying to get my window and heating sorted with my letting agency for 8 months, they sent all different people to have a look and no one could fix it! finally they got Shermin in from Sigma and he sorted all the issues within an HOUR!!! absolutely fantastic!! I have asked my agency for any future issues I would only want Shermin to sort the issue!!
Thank you so much!
