General Contracting Services With Cost and Scheduling Advantages

Founded in 1972 in St. Louis as Guarantee Interiors, we built our business primarily as a contractor for tenant and interior finishes.  Along the way our clients asked us to perform additional construction services, eventually serving as a general contractor on many projects.  Today we continue to self-perform drywall, painting, flooring, carpentry and other finishing services on a stand-alone basis, as well as on an increasing number of our general contracting projects.  This gives us significant price and scheduling advantages:

Our clients avoid the additional markup for subcontracted finishing services.

We can complete projects more quickly and give the client greater flexibility in delivery dates.

Quality control and client communication is improved because of our direct control over these finish services.

We are a client-driven, user-friendly, detail oriented and value conscious general contractor with a high percentage of repeat customers.  We understand that everyone we work with – including the owner, architect, engineer and other contractors – need to be on the same page from the very outset of a project in order to address challenges, communicate effectively, ensure success and achieve client satisfaction.  This is why our clients and subcontractors can expect a working atmosphere of teamwork, transparency and trust from us.

We believe that safety on the job site is best achieved through site-specific training, briefings and communications among all contractors, workers and supervisors. ‘Safety First’ appears on our hardhats and shirts because we proudly protect the health of everyone working with G. I. Construction.
