Alex and his team are top notch. Even though they encountered several unforeseen problems they garnered additional experts and worked through them until they were solved. Their access to expertise and willingness to get the worked completed is why we use T&G

We had a partially collapsed sewer drain, discovered after the drain specialist cleaned it out and filmed the collapsed portion. They advised restoration with a "cure in place" pipe. Billy and crew who did that day-long job were professional, respectful of our time and property.

I use T&G for everything I can. Their staff is always friendly, professional, straightforward, and they are never trying to “upsell” me on things I don’t need.

Omari was very informational and cleared up my issues. Omari took extra steps by placing covers to prevent damage from his machine, plastic around the drain and walls and using simple green to clean up afterwards.

Matthew B.
Trevor came to check our furnace. He called before coming, arrived early, and put on shoe covers before starting his work. He showed and told me what he was going to do. Everything checked out fine. He was done in about hour. Thank you.
