I recently needed a new bathroom and kitchen installed. I can honestly say that Nationserv were a fantastic company to deal with. Employees I dealt with over the phone or via email were all very professional, kind and understanding. A particular shout out to Katie Lewis who was my go to contact, a credit to her company and an absolute star! I had various workmen come into my home over the months, all were really considerate, trustworthy and hard working. The two I saw most often were Thomas and Jack, thank you both for putting up with me and working so very hard! I am delighted with the results of all your labours!

Report
We had a leak and all the floor throughout had to be taken up. Darren came and done the survey and explained what was needed to be done. His team delivedered with a very high standard of work. It was done during lockdown which was more stressful for them than for me as to try and get the materials. We allways felt reassured by darren and his team. Andrea and Reece i n the office is brilliant as well. U just mention your name and they knew all about the work in hand and was always very friendly. Would highly recommend Darren his team at nationserv
