Found an excellent builder through BestBuilders for our extension project. The quote process was straightforward, the builder was professional throughout and the finished result exceeded our expectations.
We used BestBuilders to find a loft conversion specialist. Received 3 competitive quotes within 48 hours and the builder we chose delivered on time and on budget. Highly recommended.
Good experience overall. The kitchen renovation was completed to a high standard. Minor delays on materials but the builder kept us informed. Would use BestBuilders again.
