Our Story

Square Security Inc. was founded by Mark Kostiw to provide commercial clients and property developers with the best security solutions. We achieve this by designing cutting-edge solutions, using the highest quality products and having a highly qualified experienced team. All of this allows us to offer an industry leading warranty that covers our work for 3 years.

Mark has over 15 years of construction experience and has implemented thousands of security solutions ranging from small $1000 projects to large multi-site deployments with contract values exceeding $1,000,000.

Our Guiding Principles

1. Designing Cutting- Edge Solutions

Successful security solutions require a proper design. At Square, we work on projects from the design phase through installation to long-term maintenance, with this perspective we develop solutions that are not only functional but are designed for long-term reliability.

2. Using The Highest Quality Products

We only use the highest quality equipment for our security solutions. Square only partners with reputable manufacturers to ensure what goes into our customer’s properties will be reliable over the long term. Before any products reach a site they have been thoroughly tested to ensure they meet our stringent requirements.

3. Qualified and Experienced Team

Our team at Square only includes the best of the best. We hire strategically and employ top talent throughout the organization. Our entire team works hard to ensure we deliver above and beyond your expectations. All our crew leaders have a minimum of 15 years of relevant experience ensuring we are following proven installation methods on every project.

4. Industry Leading Warranty

By designing cutting-edge solutions, using the highest quality products and installing with an experienced team, we stand behind our work by including an industry-leading warranty. Everything we install is backed by a 3-year written warranty that covers any defects in materials or labour at no cost to you.

Customer Centric

We have cultivated a culture where we take care of our customers.

Innovative and Agile

Innovative and agile security solutions to meet changing market demand.

Expertise and Experience

The Difference

1. We Don’t Use Sales Representatives

Square does not use sales representatives. This means no commissions which often can be a significant amount included in the project and this means there are no middlemen allowing you to deal directly with a project manager or owner who will oversee your project from start to finish.

2.Best Warranty

We have qualified installers and use quality equipment. This allows us to stand behind what we install with a written 3-year warranty.

3. Fair Prices

We believe in delivering quality work at a fair price. When working with Square you are getting the best value for your money.

4. Customer Focused

Our organization is structured around keeping our customers happy with great communications at its core.  We never push long-term contracts as we believe that you should stay with us because you are happy not contractually obligated.

5. Easy To Use

Security systems we install are easy to use. Products we recommend are focused on what will be easy for operators to use. We support this by including operator training and written instructions with every installation.

6. Better Designs

Systems we install are designed better from the beginning. We recommend the right equipment, in the right locations, installed with the proper techniques from the start. This avoids inefficient security solutions and avoids costly change orders.

7. Fast On-Call Service

In most cases, we provide next day service and for critical issues, our team is available 24/7.
