I would have chosen a different contractor to redo my sunroom. I gave the business to my neighbor because he's my neighbor and has been in the business awhile. We even had a quote $1,000 less but we wanted to get a quality product.
However, he took 6 months to even start the job, then screwed us over and tried to charge an additional $250 when he had left tons of remodeling trash on our lawn and holes in an adjacent room.
Things got hairy, so now we have a strained relationship with someone we live next to and we're out $1,000 we could have saved.
