Our story
Working for property owners and managers for more than three decades
Since 1990, property owners and managers in Maryland, Virginia, and D.C. have hired TopKey Construction, formerly known as Installation Services, for commercial and multi-family work. We take a commercial construction project from the first site visit through completion.
We meet you on site, send a proposal for review, and set the project schedule. Then we do the work with as little interruption to your business as possible.

Testimonials
What property managers say
“Top Key has done several jobs for me at various locations. We are pleased with the prompt response and attention to detail in taking care of our needs. Top Key has worked on roof repairs, stairwells, leaks, asphalt repairs, roof hatch, bollards, etc. Top Key has done top notch work and I highly recommend this company for any and all projects.”
“TopKey Construction did a number of projects at my commercial building in Md. They did parking lot restriping, and office buildouts that included beautiful, specialized accent walls. The company was efficient clean, and very easy to work with. The work was done in a timely fashion. I would highly recommend them.”
“St. John's School in Clinton, MD has used TopKey for the past 3 summers for major construction projects to enhance the safety of our school as well as making it more energy efficient with new windows. From the sales rep to the project manager to the technicians themselves have always been professional and courteous. They are always vigilant of when students are on campus and respect their safety. We would strongly recommend TopKey for any project large or small.”
“Glen, Duane, Nancy and your team did an awesome job on the Columbia Park project. Brought to light some unsafe conditions with one of the electrical panels and repaired. Addressed the hot water heater and fountain wiring issues which were outside of the original scope of work. The overall work performed was outstanding and within the scheduled time-line despite some unforeseen items that arose with the warehouse demo portion. Thank you!”
