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.

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.

Blerim undertook the task of constructing a rear extension to my home, which involved creating additional living space while seamlessly integrating it with the existing structure. The project was quite intricate, requiring meticulous attention to detail and a deep understanding of construction techniques. Blerim's craftsmanship was truly remarkable. He demonstrated an unwavering commitment to quality, ensuring that every aspect of the extension was completed to the highest standards. His precision in measurements, choice of materials, and execution of design elements exceeded my expectations. Throughout the construction process, Blerim exhibited the utmost professionalism. He was always punctual and kept me informed about the project's progress. His communication skills are commendable, as he patiently answered all my questions and addressed any concerns I had. His ability to work collaboratively with me and the other contractors involved in the project contributed to a smooth and efficient workflow. One aspect of Blerim's work that I found particularly impressive was his reliability. He consistently met project deadlines and stayed within the agreed-upon budget. This reliability gave me peace of mind throughout the construction process, knowing that I could trust Blerim to deliver as promised. In addition to the extension, Blerim also transformed my outdoor space with his landscaping expertise. He took my vision for a beautiful and functional outdoor area and turned it into a reality. His landscaping work included planting trees, creating flowerbeds, installing a patio, and adding various hardscape features. The result is a stunning outdoor oasis that I now enjoy daily. In summary, I wholeheartedly recommend Mr. Blerim for any construction or landscaping project. His workmanship is exemplary, his professionalism is unmatched, and his reliability is unquestionable. Blerim's dedication to delivering top-notch results truly sets him apart, and I have no doubt that he will excel in any endeavor he undertakes.
