Bathroom Fitting- 21 Jan 2021
I am so pleased with the standard of work and could not recommend Blinding Builders more. My bathroom has been transformed and finished to such a high standard Michelle gave the initial quote and she was very friendly and helpful .and gave some good advice. Rob worked very hard and it was a pleasure having him doing the work. He was friendly and professional and nothing was too much for him. The quote was very reasonable I know that there are many builders on the site but I would urge you to choose Blinding Builders, for excellent work at a competitive rate

My husband and I just bought a house and we were having a real hard time finding a good builder. We registered on MyBuilder and shortlisted a few tradesperson, we then came across this amazing team from XK contractors. They have literally and figuratively been a real blessing. 10 days and they changed the look of our house to our preference. I'm not just writing this review for the sake of it, but they're honestly real hardworking people. The main man- Xhezavir leads the team like a dream and they all know exactly what they're doing. Highly recommended, decent pricing, great work team, keep up the good work!! 👍
