Latest reviews

  • Knock through wall from Dining room to Kitchen.

    I am very happy with the work that Tony and Scott carried out. Everything went as planned and I can recommend Tony and his team.

  • Convert garage to living quarters

    We engaged A Brockwitz Builders to deliver a £90k project for converting a garage into living space and refurbishment of two further rooms including replacing a roof. Tony supplied expert leadership for our project, consistently providing good advice and quickly resolving any concerns that we had. We had the peace of mind that comes from knowing that we were in safe hands.
    Tony's own team were polite, efficient and skilful and accomplished a great deal in a short space of time. We could rely on them to turn up daily and they did not disappear for long periods at a time as some builders are prone to do. They also managed to avoid unduly disrupting conduct of our normal domestic life which was remarkable in the circumstances.
    Tony co-ordinated our whole project: which was a weight off of our shoulders. His recommendations for expert plumbers, electricians and roofers were spot on and they worked seamlessly with the builders to avoid unnecessary delays.
    I would whole heartedly recommend Brockwitz Builders who oversaw a largely stress free experience for us and delivered a first class end result

  • New wider doorframe plus new internal door

    Great service from Tony and his team - came up with a great plan to solve my problem and executed it all really well (new wall, doorframe, all well plastered and finished off), plus a very friendly bunch too. Would heartily recommend
