Insurance. Injuries can occur on a construction site. If the location is your home and your contractor does not have the proper insurance, you may be held liable. Check with your locality for the proper amount of liability insurance, and if the contractor has employees, check to see whether he carries worker's compensation insurance.
Duration of work. Though projects often take longer than predicted for many legitimate reasons — some caused by the client and some outside the contractor's control — put the expected project duration in writing. The important thing is not that your contractor shows up every day, but that he finishes the project on time. Having a timeline will help calm your nerves if progress hits a slow spot.
7. Exclusions. A good contract should include a list of exclusions. These might be related to areas that will not be visible until the walls are opened up after demolition, or the level of cleaning you should expect after the work is complete. Also, talk to your contractor about the likelihood of finding asbestos behind the walls.
9. Payment schedule. While payment schedules can vary by the job, they should always be agreeable to both parties involved. In my opinion, payments tied to milestones in the project are better than those tied to percentages of completion. As long as you are confident that you're not paying for significantly more than what's been completed, you should be OK.
10. Warranty. The standard warranty for work is one year from substantial completion. If you've checked the contractor's physical address and gotten recommendations from people you trust, you'll know where to find him later if needed.
Just because it looks like a duck ... A lot of houses are still piped with copper, so repairs and remodeling will generally be done in copper as well. Half-inch copper pipe is 5/8 inch in diameter, but the thickness of the copper depends on the type. Many stores sell type M and L. Type M is cheaper because it's thinner — but saving money in materials now could mean tearing open walls later to find a pinhole leak that has sprung.
it's recommended that you withhold 10 percent of each gross progress payment as a retainer. Once the job is complete, pay the retainer in full.
