Re: Small jobs help
Hiring anyone, for anything, is a crap shoot, which is why we recommend that you try to get leads from trusted family and friends who may have service personnel they have used with good outcomes. Beyond that, you can try sites such as Angie's List for referrals.
Unfortunately, there is no way to know if the person you hire is capable of the repairs you require until you hire them and see their work. Yes, you can check references, licenses, insurance, etc., but these things don't really paint an accurate picture of whom you're dealing with.
Ultimately, you have to go with your gut feeling. How does the individual make you feel? Would you trust them with the access to your home without your presence? Do they seem knowledgeable about the services you need?
The other thing I'd recommend is to have a list of all the things you want to do, both short term and long term, to the house. While you may not need a contractor to replace the door, maybe you do need one for a bathroom remodel or other larger project. A small door project is the perfect test to see the kind of work the person does, their work habits and ethic, site cleanliness, personality, these sorts of things. If all goes well and the tradesman is compatible, then you now have someone to handle the larger items on the list.
