I recently worked with Gnetzer on a project and had a great experience. He is fast, communicative, and transparent, making the process smooth from start to finish. He kept me informed about progress, was open about costs, and was always willing to collaborate on solutions.
One thing that really stood out was his responsiveness. I discovered a leak in the house that wasn’t related to his work, and he still came by within an hour to check it out and make sure it was handled properly.
The only area for improvement would be general cleanliness—the job site could have been kept tidier at times. But overall, the quality of work and his reliability made up for it.
I’d definitely recommend Gnetzer for anyone looking for a dependable contractor.
