RS Property did a brilliant job on my bathroom; very professional and good communication with Roger throughout the project. I gave them a tight timeline and challenging materials and they worked well to get the job finished earlier than expected. They even took my bath and WC back to B&Q when they saw a small crack in them! Would highly recommend RS Property
