Extensions- 3 Jun 2020
Mohit and his team at Shivay Developments completed extensive improvement work in my house (rear extension, internal structural work, kitchen, toilet, boiler installation, plumbing and electricals, flooring & finishing). The end result exceeded all my expectations in terms of cost, time and quality making me a very happy man. Sharing some pictures would have done proper justice but unfortunately there doesn’t seem to be a way to upload pictures with the feedback. In spite of living inside the property whilst the works were ongoing, we hardly felt any impact owing to how well Mohit had planned the whole thing and the advance notices he used to give us from time to time. All the guys too were very considerate when it came to minimizing the inconvenience all the dust and noise could cause to us and also the neighbours. I also liked the fact that nothing was rushed and a great deal was given to attention for details and the result was just splendid. I guess at the end of the day, it’s what you see that matters most. However amongst everything that hit the right notes for me during the entire process, it was the confidence that I can trust this team to do the job right stood out. It was a bunch of warm and friendly people who had direction and knew what they were doing. A special mention and a big thank you to Kash and Pala to lead the work from the ground up and Mohit for taking up and managing the job and of course for the celebratory rounds of beers :) Do keep in touch

Extensions- 29 Aug 2021
Communicated well at the start with reasonable cost. work was done well but the finishing was not so great as expected. The end cost was very expensive. Charged by the hour, the team were very slow which was upsetting to see me pay for time where they sat around not doing much. Ensure to agree fixed price. Communication after job is poor, double glazing has warranty which now not being able to communicate with kostas having to pay to get things done that should be covered in warranty. Central heating give huge problems. Do not use for big jobs
