Conversions - General- 9 May 2019
VJ and his team have just finished a full reconfiguration of the downstairs of my house, taking out walls and toilet to make a large open plan kitchen, dining room living space, making a new toilet and utility room in the garage room. The team always arrived early and worked all day. Issues were dealt with swiftly and minor changes or additions were carried out! Over all I would rate VJ and his team very highly.

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
