Best Questions to Ask a Gutter Installer Contractor

Are you union or non-union?

This really only matters if you have a preference, but it is good to ask. If you have a strong ideological belief about unions or nonunions, it's perfectly acceptable to make a decision based on the preference.

Do you work with subcontractors?

The question is great for some industries and non-applicable for others. A general contractor, for example, will by definition employ subcontractors. Most Columbia Gutters companies do not, but there are exceptions. You should always ask this question to your service providers. If they do use subcontractors, ask if they're all licensed and insured independently.

Are you insured and/or bonded for Gutters?

You'll certainly want to ask them this. Steer clear of any company that is not insured in Maryland, because that means that any incidental damage they may do on your property will be a real hassle to recover compensation for. It is never wise to work with uninsured tradesmen of any kind. Most states also require that someone have insurance in order to be issued a trade license. If they say they're licensed but not insured, they're being less than truthful.

How long have you been in Gutters business for/How long have been serving the Columbia area?

You'll always want to ask how long the company has been in business in Columbia. 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.
