Plastering- 24 Jul 2025
Ibrahim has been excellent from start to finish. He has turned up exactly when he promised, tidied up after every day and the finish is super for a very reasonable price. It wasn’t a simple job as various areas needed skimming, some blending into existing plaster, plus an arch, a ceiling and a media wall but Ibrahim managed it all very well. I wouldn’t hesitate to hire him again and can thoroughly recommend.

Ste Walmsley Building Services were brilliant. It was Ste himself who came at short notice when someone else let me down the day before. He dug a trench for a hedge around the property, exactly as specified and worked efficiently to complete in time. Everywhere was tidied up afterwards. Would highly recommend.

Extensions- 25 Jun 2020
We had our porch renovated by Knowles construction a few months ago. We found Kurt and team to be very polite and professional. They went the extra mile to match window design to the existing windows. Overall their work was very neatly finished and they didn't leave a mess. I will recommend their service.

Very neat and careful work. Maybe the timing was a bit underestimated but in fairness the job did not go as expected and caused a few changes of plan. However he did work with the changes without problems.

Steve built us a garden room from scratch, and it looks fabulous. Then followed up with building heavy timber raised beds and re-flagged an area. Everything done through good project planning and a team of skilled tradesmen, including himself. He used experience and expertise to advise us the best and most cost effective way to get the job done. Steve is very reliable and makes sure a job is done properly. Would recommend him to anyone.
