Kitchen Fitting- 9 Jul 2026
I hired Blend for a light house renovation. It started off really well then towards the end he ghosted me. No reason given. He didn’t answer phone calls or texts. There was no fight or disagreement. There is no decent reason why he shouldn’t communicate with a client. You can simply just say you have another job or you are not interested any longer. You don’t ask a client to buy stuff knowing you are not going to show up. It is an unacceptable and unprofessional behaviour. Because of this it’s cost me time that I can’t get back. But I guess it is what it is. I had to find another builder to complete the job. Some of which was not done properly. For example: my kitchen sink was leaking both inside and out. Had to buy a new toilet as something was broken while he was refitting it and etc. Pros: Blend is a nice and easy person to deal with. He is generally a nice guy. Tiling ✅ Cons: Finishing is not so great. could be a lot better. I also found patches and over paint on doors and others.

Extensions- 26 Aug 2021
SSS BROTHER, They worked incredibly hard to transform our house in a timely and efficient manner, all whilst being responsive to our concerns and preferences. The SSS BROTHER did a great job extending our kitchen and backroom to create a beautiful space that we love hosting family and friends in. The job was completed to a high standard and with good communication. Throughout the work, the workers were calm and knowledgeable and - importantly for us - helpful and offered their opinion of how the extension should be built.

Tiling- 25 Jul 2025
Shiv builders did the tiling for my bathroom. The quote was easy and done via a WhatsApp video. Price was reasonable. The job turned out to be more challenging than we first thought with uneven walls and floorboards were quite worn however they found solutions easily. The team arrived on time and did an excellent job. Always left the place tidy and very polite and professional. I then had a few additional jobs round the house such as changing door handles and fitting light pendants which they happily accommodated and again did a good job. Will definitely be using them for future work.
