Strong Homes, Dry Basements, & Beautiful Backyards in Central Maryland
Supporting Your Property From the Ground Up
Your home should feel solid, comfortable, and enjoyable in every season. When cracks start raising questions, moisture keeps showing up where it shouldn't, or your backyard sits unused for most of the year, it helps to have an expert who can walk you through it, explain what they're seeing, and put together a clear path forward.
Allmaster Home Services is a family- and veteran-owned company with over 30 years of experience serving Central Maryland homeowners. Whether the job is below ground or in the backyard, we bring the same level of care to every project we take on. It’s time to say goodbye to property stress and hello to a home that stands the test of time.
Family Owned, Veteran Led, Maryland Proud
Most contractors specialize in one category, but Allmaster Home Services was built around handling more than that. We started in foundation repair and water management, and structural work remains at the core of everything we do.
Over the years, we expanded into outdoor living because homeowners kept asking the same question: once the basement is dry and the foundation is sound, what comes next? For many families, the answer is a backyard they can finally put to use.
Keeping it all under one roof means the people doing your outdoor work already understand your home's structural history. The result is a smoother process, a more cohesive outcome, and a team that's invested in your home from top to bottom.
Our Services
Our services focus on the essential parts of a home, providing structural support, moisture protection, and better day-to-day performance.
When walls start to bow, or floors begin to shift, the underlying issue rarely resolves on its own. We assess the situation, stabilize what needs stabilizing, and put the right long-term fix in place so the problem doesn't come back.
Water damage tends to start small and get expensive fast. We get ahead of it with basement waterproofing, crawl space encapsulation, and yard drainage systems that redirect water away from your home's foundation.
A backyard that goes unused is just square footage you're not getting anything out of. We design and install patios, decks, pergolas, and outdoor kitchens that give your family a reason to spend more time outside.

Testimonials
Very comfortable process from beginning to end. Helpful, insightful, professional, and competitive. Crew was hard at work on the landscaping everytime I checked in. End project looks great and I am confident in the structure and craftsmanship.
Professional and excellent customer service. Would hire them again without reservation.
Allmaster came to our home to demolish and rebuild front porch. Pictures are posted on their facebook page. It went absolutely perfect. Our porch looks wonderful. I will definitely be doing service with them again in the future.

Allmaster’s came out immediately for an estimate, did a very professional job and completed the work on a very tight schedule to meet a closing date. Both Nick and John were great to work with! I would highly recommend their company.
The customer service was very professional. Allmasters has a very hardworking crew. The job was done in a timely manner. I will definitely use them again.
Very professional. The customer service was excellent and price was reasonable. John and nick were great to work with and I would highly recommend.
I’m quite happy with the improvement in energy efficiency that was achieved by installing the radiant barrier in my attic last year. Even after installing a new energy efficient heating/AC system the previous year, the AC bill was much lower than it was the year before(barrier) and my heating bill this last, long cold snowy winter was lower than it’s ever been in the thirty years I’ve lived here! Great job guys!
Team did a great job and we would give our highest recommendation. Took time during the estimate and all through the actual project work to explain what was needed and being done. Angel and his crew are friendly, courteous, and professional.
