10/10

We had our front window and door (with storm door) replaced, along with a back patio door (that required widening the opening), purchased through Landmark. Harry and his team were very efficient, thorough and professional, yet also friendly. He consulted with us at various stages, especially when a couple of modifications needed to be made; and he ensured we were pleased with the quality, and also coached us about giving the caulking time to set. I would definitely recommend HC Windows & Doors.

At a busy time for energy audit deals, GNI was very prompt sending their assessor for a no-obligation quote, and they booked me in as soon as they could. The team who came today were in and out quite efficiently and cleaned up the mess that was created in the process. Thanks.
