Extensions- 8 Oct 2018
Alton and his team at Bluelime have been incredibly helpful and enthusiastic throughout our design and planning process. From the start, Alton took his time to understand our needs and propose several cost-effective ways to improve my home and create more space for my growing family. The design process was completed efficiently and submitted for planning permission, which was granted without a problem. Since then, his team have continued to be helpful and communicative despite my need to delay to the building works due to unfortunate complications with my freeholder.

Bricklaying- 17 Dec 2024
They initially gave a fair price and a date and timeline that fitted with our needs. Subsequently they over ordered on the bricks so we had over 100+ expensive London bricks left over and they under ordered on sand and cement.(Luckily the shop took them back but we had to deliver them there) The job took far longer than they had said although the poor weather did not help much which could not be helped. The worst was that the wall was finished so that the latch of the gate could not be fitted as the wall was a bit too long! The wall looks good but their customer service and time given for job as well as ordering materials needs some improvements. They are pleasant workers, not rude in speaking

I couldn’t be happier with the work carried out on my home. The tiling on the ground floor, the laminate flooring upstairs, and the kitchen units were all completed to an exceptionally high standard. The attention to detail was outstanding, and everything was finished neatly and professionally. He was reliable, hardworking, and clearly takes great pride in his work.

Kitchen Fitting- 8 Nov 2017
After a cowboy builder failed to install our kitchen Tomaz came to the rescue. He gave us a very fair price as he knew we had lost out money already having to replace broken or damaged parts of the kitchen. He communicates very well through the build and always called me on FaceTime to show me things he was doing in the kitchen and to ask for my preferences. If anyone needs a kitchen fitter with minimal hassle use Tomaz. The job was completed in a week, which included tiling . He fitted a howdens kitchen from scratch And it looks very tidy. Thanks Tomaz, next job loft extension !
