Dependable Fire Sprinkler, Inspection, & Repair

If you’re thinking about fire sprinkler installation in a new building or you want to upgrade the sprinkler system in an existing building to meet code requirements, it’s important to choose the right fire protection company. Don’t rely on fire system inspection companies to provide the full service you need. Keystone can do it all – fire sprinkler installation, fire sprinkler inspection, and fire sprinkler repair. And with a robust team of highly skilled sprinkler technicians, we can take on the big jobs with ease. Whether you’re looking at a traditional wet sprinkler system, a dry sprinkler system, a foam sprinkler system, a deluge system or pre-action sprinkler system, we can design and install a system tailored to fit your business. 

We have a Fire Sprinkler Team fully staffed with certified technicians who specialize in sprinkler systems, lead by designers and project managers with decades of experience.

We can install your sprinkler system, provide annual fire sprinkler inspection service and emergency fire sprinkler repair, 24/7/365.

If a fire sprinkler system is not the best option to protect your most valuable assets (your business and employees), we can also install various types of fire suppression systems for commercial and industrial applications.  Just like our Sprinkler Team, we have Suppression Specialists who are well-equipped and certified for fire suppression system inspection, installation, and fire suppression system repair.  Whether you need a large industrial fire suppression system to protect big, expensive or irreplaceable equipment that keeps your manufacturing process running smoothly or a miniature system designed to protect sensitive electronic components, our in-house design team can meet your specifications and create the most sensible solution for your business. 

We make it our business to protect your business in the Lehigh Valley, PA, and we want to be the fire suppression system repair and installation company you trust!
