Nov 14, 2020 Report

We had SAS carry out an extension for us in Harpenden, him and his team carried out an outstanding job from start to finish. We had 5 Quotations from different builders and by far Scott was the one we felt the most comfortable with and his pricing was very reasonable. We are going to use him again to install a summer house in our garden next spring.
8/5!

We had Scott booked in for a job to replace our flooring on our ground floor. He showed up on the day agreed and done a magnificent job. He also came across some damp within our living room to which he repaired at a fair price. He had his son working alongside him who was also very keen and knowledgeable, both were polite and friendly.
10/10 service, will defiantly use again.

SAS Carpentry & Building renovated two external bin stores which included replacement of the doors and repointing. The works were carried out to a high standard and have transformed what were tired and dilapidated bin stores. Would highly recommend Scott and his team.
