Boston is known for its historic neighborhoods and timeless architecture. At Alliance Deck Builders of Massachusetts, we respect that heritage while adding modern functionality. Our wood decks pair beautifully with colonial and Victorian homes, while our composite builds offer a contemporary edge for modern properties. Whether you live in Charlestown, Jamaica Plain, or Roslindale, our decks are designed to complement your home’s character while providing comfort and durability.

From icy winters to humid summers, Boston’s climate demands strong, weather-resistant decks. That’s why we build with top composite brands like Trex, TimberTech, and Fiberon, along with pressure-treated lumber and cedar for natural beauty. Our process includes proper flashing, waterproofing, and drainage to prevent rot and warping. With Alliance Deck Builders, you get a deck built to last through Boston’s toughest conditions.
Every homeowner uses their deck differently, and our job is to make it functional and beautiful. In Boston, that could mean a rooftop dining area in the Seaport, a screened porch in Dorchester, or a grilling station in South End. We design custom add-ons like pergolas, outdoor kitchens, lighting, and privacy screens to enhance your deck. With endless options for railings, stairs, and layouts, we’ll tailor your outdoor space to your lifestyle.


Back Bay: From elegant rooftop decks overlooking the Charles River to private patios behind historic townhomes, Back Bay projects balance beauty and practicality.

South Boston: Known for tight spaces and stunning views, South Boston decks often maximize small footprints with multi-level or rooftop layouts built for city living.

Dorchester: Spacious backyards in Dorchester allow for large family decks, screened porches, and outdoor kitchens designed for year-round entertaining.
