They renovated our bathroom. Very good service, professional and high-quality. Would recommend.
Alex and his team are absolutely fantastic and did a great job with our commercial extension. The team were very accomdating and ensured the business was not affected in the build. Highly recommended for a project managed build.
I've had the pleasure of working with Alex at Grand Alliance for several years now. We have always found Alex and his team to be hardworking, reliable and well priced. The team have decorated our Fitzrovia office several times, completed 8 bathroom refits to an incredible standard, recommended great carpet fitters to us and helped with general repairs. We would highly recommend them!
Alex has a wonderful team who are very professional. The work is neat and nice.
Alex and his team come highly recommended. Installed new kitchen and bathroom with internal remodelling. Very professional attitude and project planning, respected my home and didn't treat it like a building site. Above all reasonably priced for the high quality of work they do.
This is very good company.
Alex & his team did a terrific job on fitting my new kitchen. I was so impressed with them that I also gave them the work to replace all the old decking in our back garden. Again, they didn't disappoint. I wouldn't hesitate to recommend them!!
I could not recommend Alex and his team enough. He transformed my run down, almost derelict business property to an amazing, modern and stylish salon. The Pamper Suite, Bexley. He did this project in 2013 and it still looks amazing. Built to last. If I have ever wanted to change anything, he and his team have been available to assist me. I will never use another company. Grand Alliance LTD are the best. Thank you Alex.
We have used Grand Alliance on three different occasions. To do our loft extension, en-suite bathroom and kitchen refurbishment. We have always found their work to be of a high standard and high quality. The company is reliable and punctual. I would thoroughly recommend.
Really professional team, delivered exactly the results they promised in the timeline they stated and on budget. It’s hard to find good contractors / builders that deliver to exacting standards. I highly recommend without reservation, need I say more.
