Client Testimonials

Ryan built a lovely wrap around extension to our home in 2014, so warm and bright. We were delighted with every aspect of his work, very clean, reliable and has a wealth of knowledge. He came back in 2015 and converted our attic, again to a very high standard. Pleasure to deal with and we would highly recommend him to anyone.


Homeowners in Meath

We worked with Ryan on a home extension over the course of 4 months, and couldn’t recommend him highly enough. He is efficient, reliable, lovely to deal with, and a talented craftsman. He was always happy to tackle headlong any of the inevitable challenges that arose during the build, and always came up with creative solutions! We are delighted with our beautiful, light-filled extension, which we continue to enjoy spending time in every single day.


Woodley Pk, Dublin

RMS construction completed a one classroom extension to our primary school in 2017.  From the initial stages right through to completion, we could not have been happier with the professionalism, efficiency & extremely high quality workmanship that was demonstrated throughout the whole process. Our extension was completed on time & on budget & the whole school community was absolutely delighted with the final outcome.

Ours was a complicated project with  conservation & sensitive archaeological issues which Ryan & his team dealt with superbly.  Ryan was an absolute pleasure to deal with; he has excellent communication & time management skills & his commitment to providing a first class service was unwavering throughout. I could not recommend RMS construction highly enough.
