Removal and replacement of hinges on a pair of casement windows.
Posted the job, they responded promptly, came round to quote and gave a reasonable price. Having read their reviews was comfortable to move forward. The job was done well, communication was good and the finished result was what I wanted so no hesitation in recommending them. Will definitely use again should u have a need.Verified reviewerJob location: HP7RChristopher J10 General Carpentry

Jonathan and his colleague assisted with installing a integrated dishwasher and wardrobes.
Jonathan is a busy man to get a hold of but reliable and the work is top notch. He and his partner did a great job - and it was a hard one! I cannot recommend them enough and will certainly use them going forward.Verified reviewerJob location: TW8RAmy B
