Ask him
- How long have you been in business?
- Are you licensed and registered with the state as a contractor?
- How many projects like mine you undertook and completed in the last one year?
- Will my project require a permit?
- May I have a list of references?
- Will you be using subcontractors on this project?
- What types of insurance do you carry and the level of liability in it?
Look for a well-established company and check it out with consumer protection officials. They can tell you if there are unresolved consumer complaints on file. One caveat: No record of complaints against a particular contractor doesn’t necessarily mean no previous consumer problems. It may be that problems exist, but have not yet been reported, or that the contractor is doing business under several different names.
Most of the states license electrical and plumbing contractors, but only 36 states have some type of licensing and registration norms affecting contractors, re-modelers, and/or specialty contractors. There may be several forms of registration as simple and detailed one which invites a long qualification process. The licensing can range from simple registration to a detailed qualification process. Also, the licensing requirements may change from one locality to the other and may be entirely different in other state. You need to check with your local building department or consumer protection agency to find out about licensing requirements in your area. If your state has licensing laws for the contractors, ask to see the contractor’s license. Make sure it’s current and has not expired..
Ask for a list and peruse and if possible try to access the clients to confirm work satisfaction level.. This will also help you determine how familiar the contractor is with your type of project.
Most of the states and localities require valid permits from the authorities for building projects, even for simple jobs like decks, a permit is required. A competent contractor will automatically get all the required permits before commencing the work on your project. Be suspicious if the contractor asks you to get the permit(s). It clearly indicates that the contractor is not licensed or registered, as required by your state or locality.
Peruse the list of the the names, addresses, and phone numbers of at least three clients who have projects similar to yours. Ask each how long ago the project was completed and if possible see it. Also, tell the contractor that you’d like to visit jobs in progress.
If yes, ask to meet them, and make sure they also are insured and are licensed, if required. Also ask them if they were your primary contractor pays the sub contractors and the labor. A "mechanic’s lien" could hinder if the contractor fails to pay the subcontractors and suppliers on your project. That means the subcontractors and suppliers could approach the court to force you to sell your home to satisfy their unpaid bills from your project. Protect yourself by asking the contractor, and every subcontractor and supplier, for a lien release or lien waiver and if possible make him sign a document for this..
Contractors should ensure a personal liability, worker’s compensation, and property damage coverage. Ask for the copies of the documents related to insurance certificates, and make sure they’re current. Avoid business with contractors who ignore the insurance norms. Otherwise, you’ll be held liable for any injuries and damages that occur during the project.
