Best Questions to Ask a Door Installer Contractor

How long have you been in Doors business for/How long have been serving the Saint Louis area?

You'll always want to ask how long the company has been in business in Saint Louis. While this isn't a guarantee that the company will do good work, companies with longevity on their side must be doing something right. That being said, there are newer companies that do great work. If the company is under three years old, ask where the owner was employed before and for how long. If he/she has a long history of employment, it's reasonable to infer that he or she decided to go into business for themselves after so many years of experience.

How much do I have to give as a deposit?

Some companies may require a 10% deposit, some may not require any. For larger projects, you'll almost always need to give a deposit, and it's good to ask how much the deposit will be before going forward with a project. The Saint Louis contractor will know how much they need for a deposit when they've given you the estimate, so ask early.

What is your projected timeline for the Doors project in Saint Louis?

Though a standard question, it's important to ask. Most contractors will tell you how long they expect the job to take without you asking. If they don't volunteer that information, be sure to ask. It's also helpful to ask if that's a hard finish date, meaning that it's the definite finish date. If it's a soft finish date, it may be extended for any number of reasons.

How many contractors do you have working for you? How many vehicles are in your fleet?

This is important mostly for larger jobs. Clearly a two man operation is going to build a home much slower than a 15 man crew. This is also a good indication of the overall size of the Doors company, if that's an area of concern for you. The reason you may want to ask about the fleet is that fleet size is a good indicator of the mobility of the company. Mobility may not sound important, but it's hard for the Saint Louis contractors to get to job sites if they lack appropriate vehicles.
