Before you Hire

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

How important is contractor licensing in Oklahoma?

Specialty contractors must pass a trade exam to become licensed in Oklahoma.

Your liability risk when hiring Karl William Kordsiemon

Although residential contractors are not required to carry general liability or workers' compensation insurance, it is a good idea to hire only contractors with active policies for each. Request a copy insurance certificate for each form of insurance before any work begins.

Financial recourse when hiring Karl William Kordsiemon

Specialty contractors in Oklahoma are required to obtain a surety bond.

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

Before hiring a contractor in Oklahoma, be sure to get at least 3 detailed bids. Quality contractors will take the time to explain their budget proposal, and help guide you through the estimate process. Be wary of an abnormally low bid, they are not worth the risk. These underpriced projects often do not end well for the homeowner, choose a contractor you trust and can clearly communicate with. BuildZoom has made the bid collection process extremely simple (and free). Just click here to get started.
