Mission Leadership

Promax Construction General Contractor


To Provide Quality Long-Term Construction, Remodeling, and Repair Solutions with First-Class Customer Service.


With over 20 years of experience in the industry, Promax Construction has the tools to knock out any job for your home or business. We have honed are craft through years of experience and know how to get the job done right. We believe in offering great value to our customers without comprising the quality of the craftsmanship or materials. We cut costs by purchasing wholesale and developing long term relationships with our staff. We are comfortable guaranteeing all of our work. Promax Construction is fully licensed and bonded. Meaning, the customer is always protected under our coverage. When you hire Promax, rest assured the job will be done right with no head-aches. In a tough economy, many homeowners are choosing to save money by hiring independent contractors without the proper licensing and insurance. We do not recommend this practice. Not only do homeowners have no guarantee the job will be done right, they are liable if someone gets hurt on the job. Another example we notice frequently is when a homeowner hires a roofer on the side to repair a roof. 5 years later the shingles are falling off the roof. A quality roof job should last up to 50 years. The homeowner tries to call up the roofer to fix his work and the roofer is out of business, left town, or refuses to honor the guarantee. Save yourself hassle and money by getting the job done right the first time.
