Before you Hire

Here are some rules, regulations, and laws governing general contractors in Arizona:

Does Mt Southwest Construction Llc carry a valid contracting license?

Although the State of Arizona allows its residents to hire unlicensed contractors, it strongly encourages them to hire licensed contractors for remodeling or construction work.

Mt Southwest Construction Llc currently holds license 321547 (General Dual), which was Inactive when we last checked.

How important is contractor licensing in Arizona?

The Arizona Registrar of Contractors maintains high standards for licensing. Applicants are required to pass a written board exam and prove at least four years of prior, relevant work experience (this varies a bit based on specialty).

Your liability risk when hiring Mt Southwest Construction Llc

Licensed contractors in Arizona with employees are required to carry workers' compensation insurance.

Financial recourse when hiring Mt Southwest Construction Llc

Residential contractors are required to provide a consumer protection bond. This may be in the form of a Surety Bond; cash deposit in the amount of $200,000; or payment into the Residential Contractors' Recovery Fund. Under certain conditions, consumers may be eligible to apply to the residential contractors' recovery fund and receive up to thirty thousand dollars to have the work corrected or completed.

What else should I know before hiring Mt Southwest Construction Llc

Starting in '02, the ROC began performing a criminal background check on license applicants by checking their fingerprints against the FBI criminal database.

How is the BuildZoom score calculated?

The BuildZoom score is based on a number of factors including the contractor's license status, insurance status, verified work history, standing with local consumer interest groups, verified reviews from other BuildZoom users and self-reported feedback from the contractor.

Why you should hire through BuildZoom

When it comes to major construction work or even minor alterations to your home, hiring the wrong contractor could result in incomplete or defective work. You may even find yourself dealing with huge liability claims. BuildZoom does the homework for you and helps you hire the right contractor.

You should get several bids before hiring a contractor

The Arizona Registrar of Contractors recommends getting at least three written bids before hiring a contractor. Do not automatically accept the lowest bid - an abnormally low bid may indicate the contractor made a mistake and is not including the same work quoted by their competitors. We've made the bid collection process extremely simple (and free). Just click here to get started.

The best way to use BuildZoom is to let us recommend contractors for your remodeling projects.

Homeowners who hire through BuildZoom's free bidding system report high rates of satisfaction, and homeowners who research contractors online are twice as likely to be happy at the end of their project.

If you hire a contractor through BuildZoom, that contractor is accountable to us. We can enforce standards of behavior, mediate disputes, and guarantee satisfaction.
