ABOUT US

Building Dreams, One Project at a Time.

SL Carpentry was born from the partnership of Leandro and Sidinei, two master carpenters who decided to raise the bar. After years of working for others, we combined our skills to create a company that values quality, punctuality, and respect for your home.

We aren’t just contractors; we are your neighbors in Medford. Whether it’s a simple repair or a complex addition, we bring the same level of dedication and “clean work” philosophy to every job site.

ABOUT SERVICE

More Than Just a Deck, It's Your New Favorite Room.

A great deck isn’t just wood and nails, it’s where you’ll host your 4th of July BBQ, drink your morning coffee, and watch your kids play. We specialize in designing and building custom decks that seamlessly fit your home’s architecture and your budget.

Whether you need a brand-new installation, a safety repair, or a complete resurfacing, we bring 8+ years of structural expertise to every joist and beam.

SOLUTIONS

Our Decking Solutions

Custom New Builds Starting from scratch? We design functional layouts that maximize your yard space.
  • Multi-level decks
  • Pool decks
  • Attached or freestanding structures

Deck Resurfacing

Is your structure solid, but the boards look old? Save money by keeping the frame and replacing just the surface boards and railings. A brand-new look for a fraction of the cost.

Safety Repairs & Railings

Wobbly railings or rotting boards are dangerous. We reinforce structures, replace stairs, and install code-compliant railing systems (Vinyl, Aluminum, or Wood).

WHY US

The SL Carpentry Difference

Why North Boston Chooses Us for Decks?

Code Compliance

We know Massachusetts building codes inside and out. We dig the footings to the correct depth (frost line) so your deck never shifts.

Hidden Fasteners

Whenever possible, we use hidden clip systems for a smooth, barefoot-friendly surface (no popping nails!).

Rock-Solid Framing

We frame 12" to 16" on center to ensure your deck feels solid, not bouncy.

Clean Job Site

We clean up sawdust and debris daily. We respect your property.
