Kitchen Remodeling

When doing a kitchen remodel, achieving functionality should be at the top of the list. A functional kitchen adds style and a logical arrangement of appliances to enhance efficiency. From stainless steel to traditional designs, planning your new kitchen remodeling project is only a phone call away.

Basement Finishing

A basement is full of potential; from a kid’s playroom to a home theater, your basement can meet that potential, and more. Doing a complete basement remodeling project will add extra space while keeping the flow of your home practical. A finished basement can even be a rental unit for a little extra income, or to reduce your mortgage payment.

Bathroom Remodeling

Because a bathroom remodeling job can get complicated, you should hire a qualified, experienced professional. For the ultimate bathroom remodel, Promax LLC will create a luxurious bathroom that will help you to relax and unwind at the end of a busy day.

Siding Installation

Promax LLC will repair and install siding on homes, businesses, and apartment buildings.

If that weren’t enough, siding is the best way to get a return on your investment.

Warranty and Financing

At Promax LLC provides a 5 year warranty on remodeling labor and a 10 year warranty on roofing labor. We also offer financing options and lien waivers on final payments.
