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 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.

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.
