These guys have been FANTASTIC! Ryan and his crew Steven and Kyle have done an amazing job transforming my house into exactly what I had imagined it could look like. Michael helped me pick my colour and design and render a model of exactly what to expect. I couldn't be more pleased with their work and service. Highly recommend Gateway Exteriors!
From start to finish, Gateway has been a pleasure to work with. Jason runs a great team of professional installers, his crews are polite, knowledgeable and they work fast but with attention to detail. Brought my home from 1980 to 2024!
Gateway Exteriors, led by Jason and his team, delivered an outstanding experience from start to finish. We had our gutters, eaves, soffit, and fascia completed, and the entire process exceeded expectations.
Very satisfied with the job on our roof and eavestrough. Gateway were fast, professional and quick to deal with. 100% would recommend them for any upcoming jobs needed.
I have had Gateway do my eaves and my roof. They have great communication, great workmanship and got the job on time and to estimate.
We combined siding with new windows. The 3D design let us visualize colour combos easily.
