Most homeowners can find a design or two or three or four … that have most of the features they want.  The challenge is finding exactly what you’re looking for, especially when it comes to designing the home of your dreams.

 At Cornerstone, we will take your stock plans, napkin sketches, paper tracings, or simply your imaginings and use them to produce a unique design that has exactly what you’re looking for.

What People Are Saying

"Cornerstone did a wonderful job and really are experts!"

-Kay R.

"Dear Cornerstone Construction, we are extremely pleased with your attention to detail in the construction of our garage. During the planning, you were very helpful by listening to what we wanted and providing suggestions with your experience and expertise to improve on the final outcome. You provided a timetable for the completion of the project, which you exceeded. Overall, we are vey proud of the final project, and we believe it adds beauty and value to our property. Thank you for a great job.

-Frank & Sandy D.

If you live in the Garrett County area, we can not recommend this contractor enough, Cornerstone Construction. Jon & Mark Hinebaugh (and staff) were exceptional. They completed the decks in just a few days and are polite, conscientious, considerate of our property, and left no construction mess while doing the job. From our initial meeting, paperwork, scheduling, to the completion was about a month. It is a challenge to get contractors to respond or even show up for estimates. Cornerstone Construction renewed our faith!
