Best Questions to Ask a Remodeler Contractor

Does the Additions and Remodels job require permits? If so, will you be pulling them yourself?

Many jobs in New Hampshire will require municipal permits in order to be approved by the town's inspector. It's always good to ask who will be responsible for pulling those permits, and if you'll be expected to do it. You'll almost never be told to pull your own, but knowing that Portsmouth Additions and Remodels permits are required makes you appear to be a well informed customer.

Do you hire properly documented Additions and Remodels workers?

This will be answered when you ask if all employees are licensed. The only way to obtain a legitimate tradesman's license is to be a legal or naturalized citizen of the US. The company may employ people in positions that don't require a license, however, so it's wise to inquire.

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.

Is your bill for Additions and Remodels in Portsmouth an estimate or a final price?

This is very important, since an estimate is just that. Many contractors will submit a "paper estimate", meaning they've written the estimate down on paper. The bill is the true amount owed and will almost always say "Invoice" or "Bill" at the top of the page. The bill should also list the date it was issued, the due date of payment, and a list of services rendered.

How long have you been in Additions and Remodels business for/How long have been serving the Portsmouth area?

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