Kitchen Fitting- 19 Mar 2024
Highly skilled, professional and courteous Nik responded quickly to the job request and promptly confirmed the appointment for doing the work. During the initial discussion he did not try to push for un-necessary changes. He completed the work as per the requirement even going out of his way to source parts that were not matching. The work was fiddly and took longer than expected but Nik was professional about it and persisted with it on the committed times and cost. On completion, Nik tested everything was in order and left everything neat and tidy. We are looking forward to working with Nik again on the next set of changes in our house.

Tiling- 24 Sep 2025
I hired seasouth builds because not only did he give a really reasonable quote, but he also had knowledge of tiling over retrofit underfloor heating - which other tilers seemed to be really hesitant to work with. The job was done to an excellent standard - he’s a real perfectionist. It did take a bit longer than expected, due to some floor level issues which he didn’t account for when he quoted. I was really worried about the price increasing out of my budget when we started running over time, but I was so grateful to find that he was a really honest guy who stuck to the agreed quote and didn’t try to make it my problem one little bit. He was polite and friendly throughout the whole job, turned up whenever he said he would, and kept in constant contact. Really honest (I happily left him unattended in my property). Customer service was excellent, nothing was too much trouble. 10/10 would recommend.

Carpentry- 24 Jan 2021
George came to do up our hallway. He laid flooring and installed new spindles and a handrail on our stairs too. He did a wonderful job on the whole lot and we were very happy with him. We were awkward and changed our mind on the first laminate flooring that I had picked out online, he ripped it up and started again with the new flooring we picked and it was no hassle to him. George is a lovely fella, trustworthy and professional. Would highly recommend

We had the most fantastic experience with Sarunas. He was highly professional from start to finish and completed the work to the highest standard. We extended our project significantly once we realised how excellent he was and he has now renovated our whole home over an 18 month period. He was able to guide us through the process and help us make key decisions which made the experience smooth and efficient. He is extremely skilled in all aspects of building, has high attention to detail and is a pleasure to have in your home! I couldn't recommend him higher and look forward to having him back in future to convert our loft!

Extensions- 9 Nov 2021
I had a great experience hiring Victor & Co. They built a Rear Garden Extension in my house with excellent standards and finishing. Also they have done everything on time, which I know is quite difficult. I met Victor, the director of the project, every week to discuss the progress and any alterations to the original plans. He was great at explaining all the options and delivering the work. All the builders were very polite and you could see that they were very well organised with all the tools and building materials they brought to the house. When there were minor delays they were happy to come on weekends to catch up with the programmed finishing time. For the level of noise you could expect a building site can generate they were incredibly quiet. Last and not least, the quote I have from them was one of the most competitive ones I found in the market, so I can definitely recommend this company to anybody that is planning a big project.

Exquisite Design and Build recently reworked and refurbished our new, six bedroom detached house, having previously completed a kitchen extension at our last property. Andrei’s work is of an incredibly high standard. He shows great attention to detail throughout the entire process. Not only does he execute the work beautifully, but he offers great design ideas and and suggestions. With regard to contracting, pricing and invoicing, Andrei provides clear and accurate documentation which gives us complete trust in his ability to work within our budget. Andrei and his team are an absolute pleasure to work with; hardworking, punctual and tidy. I have recommended them to three other friends, all of whom chose to work with him on their extension/refurbishment projects and were equally delighted with the results. I would not hesitate to recommend Exquisite Design and Build to anyone, regardless of the size and complexity of their project.

The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!
