The Owner
Sandra Hofmeister
My journey started in Lima, Peru. My mother was Peruvian, and my father was a Spaniard diplomat and a civil engineer. My father was my hero, and as I watched him construct buildings and plan infrastructures, I didn’t think there was anything he could not do. He taught me that if I remained honest, reliable, and delivered only my best work, I would grow, and so would the community around me.
Frederick County Resident since 2010
I studied, graduated college, and became an accountant, accomplishing essential goals in the private sector. Then, moved to Florida in 2006 and continued to work in accounting. But in 2010, I needed a change, so I moved to Frederick, MD, and started in construction, a field I had never dared to dream about before. I dove in heart-first and never looked back.
A Leader Emerged
As my career evolved, I began surveying homes. I saw first-hand the effects of poor-quality workmanship, “cut corners,” and incomplete projects that left homeowners devastated by my predecessors’ work. Some clients had poor experiences with previous contractors, and I wanted to ensure that we exceeded their expectations. I advocated for better materials and experienced labor, implementing a process that improved quality and service. I earned a reputation for expecting superior work with a keen eye and a passion for my trade. A group of contractors who felt the same approached me and said they would follow me anywhere. That is how A&S Construction was born.


A Unicorn in Frederick County
I am the only bilingual female licensed General contractor in Frederick with my heritage and background. I may be small in stature, but my clients, my team, and the community know me for my big expectations when it comes to honesty, reliability, and quality output. And I’m not just a leader, but an undisputed EXPERT in Roofing and Siding. As a dedicated wife and businesswoman, I am focused on providing my clients with quality service they can trust.

"Did not know much about A&S Constrution. We contracted them to put on our new roof in West Ocean City,Md.. Could not be more satisfied with the job they did. Very reasonable priced, great job, and the clean up; we did not know they were at our home. Customer service,great would refer them to anyone . Thank for the Great Job."
- Jane Emerson

"Just had the roof replaced on our house yesterday and I was totally impressed. initially we had a small issue with the fact that shingle manufacturers are not making all the colors that they used to, I had an old piece of the original and Sandra matched it perfectly. If you are looking to have a new roof installed I would definitely use A&S again."
- David Schmitt

"A&S Construction, led by Sandra, was amazing to work with. She quickly responded to my inquiry for a front porch roof repair, her team assessed the project within a day, she provided a quote (much less than others I had received), and her team completed the work within a week! The work was professionally done, looks amazing, and her team was exceptional."
- Nathan Gorka

"Sandra and her team did a great job updating and replacing the siding on our home. The started the big project and were here daily sometimes working long days until the project was completed. We are delighted with the results. Many Thanks Sandra!"
- George K.

"So happy with my experience with A&S construction! They get back to you quickly, keep you informed as to what's wrong, and how much it will cost to fix. They quickly came out, figured out what needed fixed, and were able to fix it in the same week. Highly recommend!"
- Danielle Bone

"I had a roof leak in a home that's under 3 years old. I called many places and understandably they wouldn't be able to come out till later in the week due to all the recent rain. I called A&S Construction and Sandra was wonderful. I'm extremely grateful that I only had water leaking from my ceiling for such a short amount of time before getting it fixed, all thanks to A&S..."
- Katie Riley

"The owner, Sandra, is a remarkable & impressive lady. She has a strong sense of customer loyalty and runs her business to benefit the client. The staff are extremely thorough, detailed oriented, and dedicated to their craft. I would absolutely recommend Sandra and A&S for any roofing needs you have....you won't be disappointed!"
