Exceptional Customer Service and Products
The majority of reviewers have praised Thomson's Builders Merchants, a family-run local business, for their excellent customer service, competitive prices, and helpful staff. Reviewers have commended the merchants for their prompt delivery, with some commenting on how they beat larger online retailers for price and speed of delivery. Many have expressed their loyalty to the business, stating that they will continue to use Thomson's for all their building material needs.
Parking and Delivery Issues
However, one reviewer has expressed dissatisfaction with the business. Aleksandrs Vinogradovs was unhappy with the delivery process, stating that the staff did not rearrange the goods upon arrival, despite being asked to do so. This resulted in the goods being placed in a way that restricted access to a car parking space.
