Gave an honest appraisal of the door which will need replacing and still managed to get the lock to work as a short term measure. Many thanks.

Had a quote for roof repair which included for 1 missing tile, re fitting existing tiles, repairing flashing and gutter cleaning did not accept quote. On advice from another roofer just had the one missing tile replaced since there was no evidence of any leaks inside the loft or 2nd floor ceilings.

Gurpreet fixed two steamed up windows where the seal broke. It was originally for 1 but the quote was excellent and offered the second for a small amount. Excellent work. Great price. But not excellent timekeeping or communications. I had to chase him several times. Most importantly, Great job. Neat and very polite. Will choose again. Thank you.
