One company. One Call.

If you’re looking for fire sprinkler companies in Philadelphia, or maybe you have multiple locations and need fire safety services in NJ, or fire companies in Bucks County, PA, Keystone can help. We serve Pennsylvania, New Jersey, and Delaware. Call us at (888) 641-0100  or send an email to [email protected] to inquire about services like fire alarm testing, fire safety training, and fire extinguisher service, or to get a free estimate on fire suppression systems installation or fire sprinkler repair. 

Philadelphia area business owners and facility managers have trusted us to be their fire alarm company for over 65 years, and with our proven track record, they bring Keystone on board for all their fire protection needs. We can inspect, repair, and install all types of fire alarms and suppression systems, from simple sprinklers to state-of-the-art industrial fire systems. Many others are solely fire sprinkler companies and are not equipped to handle large jobs, but we have the team of certified, expert technicians able to tackle any fire protection project with ease.


While we have become known as the fire protection company to call for fire sprinkler inspection and installation of fire suppression systems, we also provide fire safety training to help make our Philadelphia area communities safer.  We believe it’s this dedication to educating the public about fire protection that sets us apart from other fire protection companies.  Fire suppression systems can help put out a fire or limit the spread, but fire safety training and fire extinguisher training can help your employees and other building occupants safely escape.

If you’re a maintenance manager or business owner in the Philadelphia area who is interested in fire protection or fire safety training, give us a call to find out more.

Our approach: Keystone takes the time to tailor the training to your facility’s potential risks.  We teach your employees how to safely and properly use a fire extinguisher with our classroom and hands-on live burn training session. We are also happy to help your team create a successful emergency exit strategy. Finally, we combine this training with fire detection, fire protection, and fire prevention education so your employees know exactly what to do the second they see a fire or hear the alarm sound.

Of course, fire detection and fire protection safety training won’t be very useful if you don’t have the proper equipment to combat a fire. When you inquire about fire protection and safety training, take a moment to ask us about important maintenance services like fire alarm inspection, fire extinguisher inspection, fire sprinkler repair, and fire suppression system repair. In cases where an inspection reveals your system needs a complete overhaul to comply with current codes and standards, we can also provide you fire sprinkler, fire alarm installation and fire suppression systems installation.  We take on jobs of all sizes, so call us for the big projects that other fire sprinkler installation companies can’t do on time and under budget.


If you want to have the best chance of stopping a fire in its tracks, you need to make sure your equipment is in good working order. We can provide you with annual fire extinguisher inspection and other fire extinguisher service, like hydrostatic testing, to ensure your extinguishers are structurally sound and fully charged.

Did you know fire extinguisher inspections should occur monthly at your facility? An in-house expert (this can be a facility or maintenance manager, for example) needs to be regularly checking to make sure the extinguishers are accessible, labeled, and fully charged. Annually, a trained fire protection technician must inspect your extinguishers to meet fire codes and standards. Extinguishers designed to fight special fire hazards require further maintenance like 5-year hydrostatic testing, 6-year maintenance, and 12-year hydrostatic testing depending on the type of cylinder.


Fire alarms, horns and strobes, emergency lighting, and exit signs must also be maintained for proper operation. Keystone is one of the best fire alarm companies in the Philadelphia area, offering fire alarm inspection and fire alarm testing to give you peace of mind.

Your fire alarm system is likely tied into your fire sprinkler or fire suppression systems, so it is important they work properly to accurately sense a change in your fire protection systems and alert building occupants accordingly. Prevent false alarms with our fire alarm inspections. We offer fire alarm testing at your convenience, meaning we will work around your schedule and limit testing to outside of business hours, overnight, or on weekends to ensure your system is working properly without disturbing operations, employees, or other building residents.

If you’re looking for fire alarm system installation companies in the Philadelphia area or if you’re looking for fire alarm testing in Princeton, NJ, you don’t need to look any further than Keystone Fire Protection.  Call us for any of the following:

Many people used to think of Keystone as just a family-owned sprinkler inspection company that serves Philadelphia and surrounding areas. But we are so much more! While we are still that same family-owned operation, we can offer a variety of commercial and industrial fire protection in Delaware County or commercial fire alarms in Delaware, as well. Other Philadelphia area fire sprinkler companies may not serve such a large geographical area, so when your business has multiple locations, call the team that can reliably handle them all – Keystone Fire Protection Co.

We Offer the Best Fire Sprinkler Services in the Philadelphia Area

One of the most common types of fire protection services we provide is fire sprinkler installation. Sprinkler fire protection is appropriate for a range of commercial locations including retail stores and restaurants, and even large office buildings. Marco is often the trusted fire protection company when it comes to large-scale fire sprinkler installation for new construction apartment buildings. Whether you are looking for fire sprinkler installation or fire sprinkler repair, Keystone Fire Protection Co. is one of the best fire sprinkler companies in the Philadelphia area. We can even provide emergency fire sprinkler repair for those times when your older system suffers from corrosion or when your pipes burst due to a common winter freeze break.

When you hire us for your sprinkler fire protection needs, you can be certain that your install will be done correctly the first time and at an affordable price. And you will not be left hanging, wondering how to properly maintain your sprinkler system because we can provide fire sprinkler inspection that keeps your system code compliant. We are the sprinkler inspection company with decades of experience in both fire sprinkler installation and fire sprinkler repair, so you can rely on our team for the lifetime of your sprinkler system.

Trusted Fire Alarm Testing and Installation

Typically, your sprinkler system is integrated with your fire alarm system – so why have two different companies service these systems? Trusting a sole fire protection company like Keystone ensures you have a team that is not only familiar with each of your systems but experts in how your systems seamlessly work together to provide the best life safety solution for your building.

In addition to providing fire alarm inspections, we can also provide fire alarm testing tailored to fit your schedule. In schools, we ring bells on the weekends or during the summer when students and staff are out of the building. In warehouses and offices, we can test your system overnight so we do not disturb operations. When you look for the best fire alarm repair service in the area, you want a team that will respond immediately, not a few days or weeks later. Keystone offers 24/7/365 emergency service so you never have to wonder if your system will work when you need it most. This includes emergency fire sprinkler repair, too!

Commercial and industrial fire protection is too important to leave to less experienced fire protection companies. Choose Keystone Fire Protection Co., the one that has been trusted by Philadelphia area businesses for nearly five decades.

One Solution For All Your Fire Protection Needs

You need a fire suppression sprinkler system that will be there for you when you need it, so don’t bother calling fire sprinkler companies; call a reliable fire protection company to be your singular solution. Keystone Fire Protection Co. has everything you need in a commercial fire protection company – it’s in our name! We’re more than just a sprinkler inspection company; we can do it all!

Of course, your fire suppression sprinkler system can help stop a fire in its incipient stages, but how are your occupants going to know to evacuate if your fire alarms are not working correctly? Regular fire alarm inspections are crucial to ensuring your system will do its job when a fire breaks out. We’re one of the only fire alarm testing companies that also offers fire alarm repair service and fire alarm inspections, as well as a wide range of other fire protection services for businesses in the Philadelphia area.

Industrial fire protection is another strength of ours. Industrial sites are particularly challenging for small fire protection companies, mostly due to the size of industrial operations and increased risk of fires. Installation of industrial fire suppression systems and industrial sprinklers must be performed according to local building codes to ensure fires can be contained. Some fire sprinkler companies in the Philadelphia area may not be up to the task, but Keystone Fire Protection Co. can handle all the jobs you would expect of a commercial fire protection company, and we have great relationships with fire marshals all over the tri-state area who help ensure your systems meet code requirements.

If you need industrial sprinklers installed or any other type of industrial fire suppression system, we’re the commercial fire protection company to call.

Trust Keystone for any of the following jobs:

  • Emergency Fire Sprinkler Repair
  • Commercial & Industrial Fire Suppression Installation, Inspection, and Repair
  • Commercial & Industrial Sprinklers Installation, Inspection, and Repair
  • Fire Extinguishers
  • Integrated Security Systems
  • Professional Services
  • Field Services

For all these fire protection services and more, don’t call the other fire protection companies; call the commercial fire protection company that area businesses have relied upon for decades. Call Keystone Fire Protection Co. today.

At Keystone Fire and Security, we are passionate about fire protection. A critical component of any fire protection system is a fire sprinkler system installation.
