Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!
