4 years have passed since our entire house was kitted out with new doors and Windows. We chose Marlin after seeing the effort they went through to create a quality product and recieving educated advice what best suited our needs.

The choice to go with Marlin pays us back every day. Great advice on what Window type & glass treatment to use, excellent product and build, and good communication. 4 years on, I feel we made the right choice. Recommended.
