Would Absolutely Use Them Again
Donald and Caroline were great in accommodating all of our needs and changes throughout the renovation of our parents' condo. They always kept open lines of communication, and made sure that we knew how any changes affected the total price of the project. We would absolutely use them again in the future.

203k Gut Rehab
Beantown Builders was a very professional with us. We completed a 203k gut rehab with them, and it was a good experience. The work was completed on time, and the project turned out great! The PM assigned to my job was awesome, and the owner took a vested interest in it as well, helping me through the design and lending process. Would highly recommend!!

Boston’s Historic Triple Deckers: What Are They?

Most triple deckers in Boston were built between the late 1800s and early 1900s, during a period of rapid population growth. Historians estimate that roughly 15,000 triple deckers were built in Boston and nearby cities between 1880 and 1930 to provide housing for the rapid expansion of working families and the influx from immigration.

Because these buildings are often more than a century old, renovation projects frequently involve updating aging systems while preserving original structural elements. Many still feature wood framing, stacked apartment layouts, and classic porch structures that run along the front or rear of the building.

Our renovation approach balances modernization with preservation. We help owners upgrade their buildings for comfort, efficiency, and safety while maintaining the design elements that define Boston’s historic housing stock.

Multi-Unit Renovations

Complete Triple Decker Remodeling Services

Our team provides comprehensive services designed specifically for three-family homes and multifamily properties, including:

Interior Apartment Renovations

Many Boston triple deckers retain their original floor plans. While these layouts remain functional, interior finishes and mechanical systems often need updating.

We renovate apartment interiors to improve livability, durability, and rental appeal. Common projects include:

  • Kitchen remodeling and modern appliance upgrades
  • Bathroom renovations and plumbing updates
  • Flooring replacement and refinishing
  • Electrical upgrades and lighting improvements
  • HVAC system modernization
  • Layout adjustments to improve flow and functionality

Porch Repair, Replacement, and Reconstruction

Porches are one of the defining architectural features of Boston triple deckers. Stacked front or rear porches provide outdoor space for each unit and contribute significantly to the building’s appearance.

Because these structures are exposed to weather year-round, they often require repairs or reconstruction over time. We provide complete triple decker porch renovation services, including:

  • Structural repairs and reinforcement
  • Porch column and railing replacement
  • Decking upgrades using modern materials
  • Stair reconstruction and code updates
  • Drainage improvements to prevent water damage

Structural Repairs for Aging Buildings

Triple deckers may look simple from the outside, but they rely on structural systems that have endured decades of wear. Foundations, framing members, and exterior materials sometimes require repair or reinforcement.

Our renovation team can address structural issues while maintaining the building’s integrity. These improvements help extend the life of the property and ensure the building remains safe for residents.

Exterior Renovation and Restoration

Exterior upgrades can dramatically improve the appearance and durability of an aging building. Common projects include siding replacement, window upgrades, roof repairs, and trim restoration.

These improvements do more than enhance curb appeal. They help protect the structure from moisture intrusion and harsh New England weather.

Thinking About Selling Your Triple Decker?

If you’re planning to sell your triple decker in the near future, targeted renovations can make a major difference in buyer interest and the property’s final sale price.

Buyers often look for properties that already have updated kitchens, bathrooms, and building systems. Even a couple modest improvements can help a property stand out in this competitive market.

At Beantown Builders, we frequently work with homeowners and investors who want to prepare their triple decker for sale. Strategic upgrades such as porch repairs, exterior improvements, and interior updates can make the building more attractive to buyers and reduce inspection issues during the transaction process.

Triple-Decker Remodeling FAQs

What is a triple decker house?

A triple decker is a three-story multifamily home with one apartment on each floor. This housing style became popular in New England during the late nineteenth and early twentieth centuries as cities expanded and workers needed housing close to transit and employment.

These buildings are typically wood-framed and feature stacked floor plans, shared staircases, and outdoor porches. Today they remain a defining feature of many Boston neighborhoods.

Most triple deckers in Boston were built between 1880 and 1930. This means many of them are more than 100 years old and may require ongoing maintenance or modernization to remain safe and functional.

Because of their age, renovation projects often involve updating plumbing, electrical systems, insulation, and structural components while preserving the building’s historic character.

The most common renovation priorities include kitchens, bathrooms, and building systems such as plumbing, electrical, and heating. Exterior elements like porches and siding also frequently require repair because they are exposed to weather.

Older triple deckers may also need structural work to address framing wear, foundation settling, or aging roof structures.

Triple decker porches can remain safe for decades when properly maintained. However, older structures may require reinforcement or rebuilding to meet modern building codes.

Regular inspections and timely repairs help prevent safety issues. If railings, columns, or decking materials show signs of deterioration, renovation is often recommended.
