RLM are an absolute pleasure to deal with, which sounds weird when you're talking about buying doors, but it's true. It's such a relief to not have to worry about feeling sold-to or misled - there was none of that! When fitting day came, the crew did a great job and didn't leave any mess or damage. Finally, I could not be any happier with my fancy new doors 🙂
all new windows at the front of our house, plus a new front door. The quality of the work and product is excellent and Ricky and the team have been a delight to work with. We got fitted earlier than planned which was a lovely bonus.
Fast forwarding to the installation, everyone who worked on the job was polite, professional and did their job well. With good people come come good results and we couldn't be happier with the outcome. During the build we were kept informed of what to expect, and the site was kept exceptionally tidy. At the end everything was checked and cleaned (to spotless) which was unexpected from experience with other companies.
We wouldn't hesitate to use RLM agin!
