UPDATE: Just over 1 year in and we are still using General Builders for our drywall, insulation and metal. They have continued to provide outstanding customer service. They are reliable, accommodating and their pricing is very competitive. I would not hesitate to recommend them.

We have used General Building Materials for our last few orders. Shane and Tam are very easy to deal with. Their pricing is very competitive, and they have been on time to every job. I would not hesitate to recommend them.

I’ve been working with General Building Material for a month, and already can’t recommend them enough! Their prices are very competitive, but what truly sets them apart, though, is their outstanding level of service.

From the very beginning, their sales team has been exceptionally cooperative, always ready to assist with any questions or concerns I have. And when it comes to delivery, their team is punctual and incredibly helpful.

If you’re looking for a reliable supplier with great prices and top-notch service, General Building Material  is the way to go!
