9.67 Full house renovation with kitchen extension and loft conversion
Posted 03 January
Bart and his team are very good. We did 2 large building works with him, one being home renovation with kitchen extension and 2 years later we worked with him in a loft conversion. Good time and budget management and also very reliable to come and fix issues after building works. Would highly recommend!Verified reviewerJob location: SW209.25 Loft conversion

Excellent experience with Bart, Andrew and their team. Very efficient and good communication, which made the process easy for us as the client. The work was completed to a very good standard and they made excellent suggestions and went beyond what was asked of them. The project was completed in good time without any complications.Verified reviewerJob location: HA610 Quartz worktop and backsplash fitted in kitchen.

Started on agreed date always started at 8am and worked full days. Work progress was good and always a clean and tidy site was left. Accommodating changes and new ideas along the way was not a problem. Plans for planning permission were good and straightforward. All trades involved were friendly and professional.Verified reviewerJob location: TW310 Removal of internal and external walls and installation of bi-fold doors

Fantastic experience. Bart and his team are all great, very collaborative, tidy, efficient and most importantly very reliable and reasonably priced. When I requested extra work to be done, it was accommodated and all at within the timelines initially stated. All the craftsmen were very professional, completed the work to a high standard and really went the extra mile to look after my property. Really happy with the end result and would highly recommend Bart for any work.Verified reviewerJob location: N710 Painting externally and internally including redecorating.

The job was carried out professionally and efficiently. Any changes we requested "midstream" were accommodated. I am very happy with the end-result. The price charged was fair and appropriate. The team were courteous, polite and tidy and responsive to requests.Verified reviewerJob location: W410 Complete new bathroom refit

Bart was very helpful in all stages of the process, from the initial discussion of our requirements and his advice. On that basis, we took him on. All the craftsmen that did their part were very professional and completed the work to a high standard. They were mindful to cover the floors beforehand and tidied up afterwards. They were consistent with their timekeeping and so you knew where you stood. We had a few issues with delivered items that were faulty and so it delayed the completion but Bart was very understanding and took things in his stride and the stress out of the situation from us.Verified reviewerJob location: TW29 Ground floor extension and kitchen fit

Really helpful with planning the job and getting required permissions and regs. Build work done on schedule and to good standard. Standard kitchen fitted with bespoke adjustments. Always able to resolve any issues and find happy solutions. Continue to provide post job support.Verified reviewerJob location: HA110 House extension.
Posted 12 January 2024
Bart and his team were excellent and a lovely group of people to have working on our home. Bart was attentive to our needs, and open to ideas that made this build special and unique to us. He made every effort to ensure as minimal impact as possible on the rest of the house. He and his team were also timely, polite and tidied up as they went along. I was pleased with the work and felt Bart and his team were good value for money. I will be using again in the future and happy to recommend.Verified reviewerJob location: TW210 Outbuilding
