Tips to consider when selecting a contractor
- Ensure the contractor has a valid trade licence
- Do not get pressured into signing anything
- Always get a written estimate and at least three quotes
- Get a fully itemized estimate and make sure the details are written into a contract
- Get other quotes if you are asked to give a down payment of more than 5% to 15% of the total contract price
- Determine if the job requires a Building Permit. It is your responsibility to get a Building Permit, if you need one, before you start construction

The City usually only investigates contractors if a complaint is made. If we receive a complaint of anyone operating without a valid licence, we ensure compliance with Hamilton’s Licensing By-Law No. 07-170.
Inspectors can carry out random spot checks to see if a contractor is operating with a proper licence.
