"Every contractor needs to set a payment schedule tied to reasonable milestones," Mr. Crenca said. "Legally, contractors must split the bill into three payments, one at signing, one when the project starts and one at completion. For big jobs, we spread it out to five or even 10 payments."
"It would have been far less costly for us to do the job from the beginning," Mr. Crenca said. "She had paid for a new slate roof, but the slate was extremely thin, improperly installed and not consistent with the elegance of the rest of the house. She had to spend another $24,000 just for new slate. Her original contractor had estimated a cost of $175,000 but we would have estimated about $275,000 for that job. In the end, it cost her more than $275,000."
