There are plenty of professionals in your area who are more than willing to take on the job, but if you don't know how to hire for siding, you might end up with the wrong siding contractor.
It's not enough to know that your contractor has insurance; you need to see a copy of the insurance policy for yourself. If a contractor accidentally damages your home on the job, their policy will need to be able to cover the repair costs, and the right contractor will also insure against worker injuries to make sure that you don't end up paying worker's compensation.
You'll need to make sure that the siding contractors you like will be able to the job before you go on. Ask how many jobs like yours they've done in the last year.
Shop around when selecting siding contractors, and getting written estimates from each of the companies you're considering can make it easier to choose a winner. When you ask for an estimate, make sure to stipulate that all costs need to be included. Some less-than-reputable contractors will try to hook you with a low estimate and then throw in additional costs, such as parts and labor, once the job is done.
