  • New Bathroom

    10Verified Review

    From start to finish Val was very easy to work with, he offered advice from his experience to help us get our lovely new bathroom. He works hard to get things finished in a timely manner. Everything was left clean and tidy and came back when a few of the finishing touches were delivered after he had finished (blind, shelf etc )

  • Refurbishment - I would not recommend them

    5.25Verified Review

    Speedy removal of carpets, skirting, and wallpaper, fixing timber floorboards, and plastering. I ended the job early as the quality of decorator work was terrible (especially skirting) and they kept insisting on increasing the cost of items already quoted for. If you hire them, you'll need a very detailed written breakdown e.G. Exact number of lights. At the end of the job, Valter refused to return my house keys unless I paid him immediately in an in-person meet up. As a lone woman, I felt very threatened by the situation.

  • Installation of paving stones and fence at the front of my property.

    10Verified Review

    Valter and Zeban did an excellent job from start to finish. They really transformed the front of my house. Valter also carried out a few additional jobs ie changing 2 light fixtures, attaching new curtain pole. This is Valter’s 2nd job for me as he installed a loft ladder and hatch last summer. I wouldn’t hesitate to recommend him and the quality of his work.

  • Bathroom and bedroom repairs (water damage) and installing exterior drains.

    10Verified Review

    Valter and his colleague Zieber, are quite simply the best builders/multi-skilled tradesmen I have ever used! I would give them 11/10 in all categories if I could. They turned up on time every day, worked meticulously hard, and tidied and cleaned up immaculately at the end of each day. Additionally, the work they did was above and beyond my expectations. For example, when installing the exterior drainage gulley, they also installed a new damp proof course free of charge. Their work is of an extremely high standard, and I will only be using Kozi Construction for all future home improvements.

  • Garage Conversion

    10Verified Review

    Excellent work, Valter and the team did a great job and kept me updated throughout this work. The garage conversion is much better than I originally expected before starting the job.

  • Wall Ties in the loft space

    10Verified Review

    Valter carried out a professional and clean service to implement wall ties in my loft space. After checking the surveyor report, Valter managed to source the required materials to ensure the external wall of my property is secured against potential movement.
