Professional power washing services in MA and NH

GJM Construction & Maintenance is your trusted provider of comprehensive power washing throughout Massachusetts and New Hampshire. Over time, dirt, grime and mold can build up on your exterior surfaces, resulting in an unsightly appearance that can detract from your business in two ways.

First, customers can be turned off by an unsightly exterior. They often equate the professionalism of a business with its outward appearance and may choose to go elsewhere if you can’t show them a neat façade. Secondly, a neglected exterior can lead to accelerated deterioration over time when it comes to materials like siding, concrete and pavement. Translation? You’ll be spending big bucks soon on unnecessary repairs you wouldn’t need if you had just kept up with the property to begin with.

GJM specializes in NH commercial power washing that peels away the layers of grime to reveal the natural beauty of your surfaces. Our technicians are highly trained in achieving the perfect blend of power washing essentials. These four basic elements must be perfectly combined to achieve a clean surface safely:

  • Water pressure
  • Water flow rate
  • Cleaning solution used
  • Temperature of water
We have been doing this for the last 25 years in MA and NH, so we know how to make all of these elements combine to give your exteriors that glow you probably haven’t seen in a long time. Our state-of-the-art power washing machinery can cut through the layers of grime while leaving the base material intact and damage-free.

GJM helps put your best face forward for your clients, employees and customers with the following power washing services:

  • Paint surface preparation
  • Removal of lime, scale and calcium deposits
  • Removal of mold and mildew
  • Commercial building cleaning

Let us help you boost your commercial property value, curb appeal, surface longevity and safety with our commercial power washing services in MA. Sometimes you need power washing on an emergency basis, such as in the event of graffiti that pops up overnight on your retail store exterior. Other times, you simply need a seasonal cleaning of your sidewalks or just keep up with general maintenance.
