Capstone Wellness Challenge and Donation to Gather

Capstone Supports Gather, a charity organization providing food assistance in the NH Seacoast area.

In lieu of sending holiday gifts to our customers in 2020, Capstone donated $10,000 to Gather!

Capstone employees and family members also participated in a wellness step challenge of “walking” the perimeter of our service territory and completed it by taking over 5.5 million steps and covering just over 2,600 miles! With this challenge Capstone employees donated hygiene items to Gather and Capstone matched the employee donation.

Patti Gormley, the Development Director from Gather, writes “A million thanks for your great team effort and treasured donations! Our members will feel like they hit the jackpot. I hope you can envision their smiles and relief. Capstone made a huge difference for many, many people today.”

About Our Company

Capstone provides a relationship-driven service experience

You’ve heard the story before, you may also have a story of your own—two guys start a company in their garage because they want to change the world… passion runs deep, hard work ensues and dreams are realized. More often than not, it’s simply taking action with your intentions to “change the world” that contributes most to the outcome of your business venture. Will success be reached? Will the economy absorb your lifelong plans to achieve your dream? That’s ultimately up to you and is largely dependent upon the amount of drive, passion and hard work you commit to your dreams


Our Corporate Culture

Capstone Mechanical is a culture-focused commercial HVAC company

Our people make us who we are—their character, attitude, creativity, individuality, and their compassion drive our corporate goals, decision making and the approach we take with each new relationship we forge. We think of our customers as much more than simply “a company”—they’re real people with real needs, concerns and expectations. We treat every customer as a relationship—and we treat each relationship with courtesy, kindness, devotion and dedication. The purpose of this culture statement is to demonstrate the values we live each and every day as well as the manner in which we communicate with our customers and foster the relationships with share.
