I hired GL Contractors to enclose a big part of my basement ceiling that had been left open for years. For me there were two objectives:
1. fire separation &
2. sound insulation.
The contractor had to achieve this while dealing with a very challenging mess of ducts, electrical wiring, gas and water pipes in a 100+ year old house.
Using Firecode X 5/8" drywall and the double layer of Roxul requested, the contractor did a fantastic job. He met the challenges with thoughtful - occasionally outside the box - solutions that complied with my need for results that were both attractive and very, very sound. I found the contractor, & the workers he brought in, to be friendly, respectful, diligent, capable and honest.
He listened carefully to my wants and did his best satisfy them in the real world! He always arrived on time & stayed exclusively focused on my job until it was finished. And it was finished, ON SPEC (totally meeting my two objectives) & ON SCHEDULE.
Best of all, he tidied and swept up at the end of every work day.
