I had my basement done in 2018. Drew my own plans, not to scale but very close. Got 3 quotes and they were as different as night and day. We do this we do not do that.
I was going to do my own plumbing and move a water tank (with help of a master plumber/gas person and my own supplies) saved lots of labour and on my own time; new sewer lines, custom bathroom, water gas and fixture installation. . .I could have bought my own electrical supplies at almost cost, not. I did decide and made my comments insurance . . . Timeline was 6 weeks. He did what was needed and if it was not what I wanted it got fixed right there. I wanted LED counter lights in another kitchen, NO problem . . . No charge, never a no charge , a small addition, generator hook up cost me $100 (a tip) he did the box work. YET, a six week job went to 8 months. I had no care what was the hurry was just get it done, he never shut me out and any changes were done. I never agreed with him suppling what he had no idea on anything I wanted so we agreed, I would purchase kitchen/counter installed, flooring, bathroom fixtures and flooring, he installed. got these a great prices while I shopped and got quotes. The project turned out amazing. We collaborated and agreed, he gave some and I did my own thing to find what I wanted at the right price, a nice project with no nightmares. We sat and had many espressos with home made goods my wife supplied while they worked.
Just a happy ending.
