Established in 1983, Glenmark Construction Company Inc. was founded with the mission of top-quality workmanship, fair pricing, and a safe working environment for all of our employees. We have maintained these core ideals throughout our on-going relationships with some of the Midwest’s best general contractors, owners, and developers.

As a full-service general contractor, Patterson-Horth provides a wide variety of construction services, among them traditional contracting, construction management, estimating, scheduling, constructability review, procurement planning, and value engineering. Our owners are involved on every project to ensure that our service is responsive and of the highest quality. That approach builds customer satisfaction and long-term working relationships. While estimating is underway, we also begin scheduling and sequencing to achieve the promised objectives within your timeframe. Through careful planning that's based on realistic factors, we'll meet critical dates and keep costs under control. As a merit shop firm, we work with both union and non-union workers to provide the most effective, most quality-oriented teams for every project. They're led by experienced project managers and field supervisors, and work in conjunction with hand-picked, top quality subcontractors. Once the job is complete, we stay in contact to ensure that your work continues to meet your standards of quality.
