At A&S Construction, we believe that true craftsmanship goes beyond tools and materials. It’s built on trust, integrity, and a deep commitment to the community we serve. What started as a local roofing and exterior company has grown into one of Frederick’s most trusted names in home improvement.
This year, A&S Construction won the SASS Choice Award for Best Home Repair Company for the fourth consecutive year! We also recently won Best Minority Owned Business and were named a finalist for Best Roofing Company (for five consecutive years) for the Frederick News-Post’s Best of the Best. These recognitions mean the world to us because they come directly from the people we serve — our neighbors, clients, and friends here in Frederick County. These awards would not be possible if it weren’t for the values and commitment of our fearless leader!
Building a Reputation You Can Trust
Owner Sandra, affectionately known as The Roofing Queen, is proud to be the only bilingual, female licensed general contractor in Frederick County — a distinction that carries both pride and responsibility. With her heritage, experience, and high standards, Sandra has built A&S Construction on a foundation of honesty, reliability, and quality that stands the test of time.
“I may be small in stature,” she says with a smile, “but I hold big expectations when it comes to doing things the right way. My focus has always been simple — serve others with integrity and provide the kind of quality that lasts.”
Craftsmanship That Speaks for Itself
Whether it’s a roof replacement after a summer storm, new energy-efficient windows to cut down on heating costs, or siding that elevates your home’s curb appeal, A&S Construction approaches each project with precision and care.
Our team combines top-quality materials with expert installation techniques to ensure every home improvement lasts through Maryland’s unpredictable weather. We don’t cut corners, and we don’t take shortcuts, because our clients deserve results that reflect the pride they feel in their homes.
Our work is guided by three simple promises:
- Integrity in every interaction. We treat every project like it’s our own home.
- Transparency every step of the way. You’ll always know what’s happening and why.
- Excellence in execution. Because good enough isn’t good enough for us.
Rooted in Community
Being a locally owned, woman- and minority-led business means more than a title — it’s a calling. A&S Construction is proud to serve Frederick and the surrounding areas, not just as contractors, but as active members of the community.
We’re passionate about giving back through local events, supporting other small businesses, and mentoring the next generation of women in business and tradespeople. Every award and every milestone reflects the relationships we’ve built and the trust our clients have placed in us.
It’s also a reminder that when you choose A&S Construction, you’re partnering with neighbors who care deeply about the community’s growth, safety, and future.
Hiring a company that gives back isn’t just good for your home — it’s good for your community. When local businesses reinvest their time, talent, and resources into the people around them, the benefits ripple outward. It means your project dollars stay local, support jobs for local families, and help strengthen programs that uplift others. At A&S Construction, every roof repaired, window replaced, and home restored contributes to a stronger, more connected community.
A Future Built on Integrity and Innovation
As we look ahead, our mission remains the same: to provide quality service homeowners can trust. From roofs and siding to gutters, decks, and window replacements, A&S Construction will continue to set the standard for craftsmanship and care in Frederick County.
Our recognitions are humbling — but our greatest reward is still the smile on a homeowner’s face when their project is complete.
