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

Your Home's First Line of Defense.

Siding serves two critical purposes: protecting your structural framing from moisture and defining the aesthetic value of your property. Old, cracked, or improperly installed siding leads to hidden rot, mold, and energy loss. We specialize in watertight installations that lower heating costs and increase market value.

We do not simply cover up problems. We inspect the sheathing, ensure proper house wrap application, and install siding systems that are durable, low-maintenance, and fully code-compliant.

SOLUTIONS

Our Siding Solutions

Vinyl Siding Installation

The most cost-effective and low-maintenance option for Massachusetts homes. We install premium, heavy-gauge vinyl that resists cracking, fading, and wind damage, available in a wide range of colors and textures.

Wood & Cedar Shingles

Restore the classic New England look. We install and treat natural wood siding, ensuring proper breathing room behind the shingles to prevent cupping and rot.

Siding Repairs

Storm damage or loose panels? We repair specific sections to match your existing exterior. We identify and fix leaks behind the siding to prevent structural decay.

Insulation & House Wrap

The most important layer is the one you don’t see. We strip old siding, repair damaged sheathing, and install high-grade moisture barriers (Tyvek) and rigid foam insulation to improve your home’s thermal efficiency.

WHY US

The SL Carpentry Difference

Why North Boston Chooses Us for Siding?

Waterproofing Expertise

We focus heavily on flashing around windows, doors, and corners. This is where 90% of leaks occur. We tape and seal these areas correctly before a single piece of siding goes up.

Proper Fastening

Vinyl needs to expand and contract with temperature changes. We nail with precision, not too tight, to prevent buckling and warping during summer and winter.

Site Protection

Siding removal creates debris. We protect your landscaping during demolition and run magnetic sweeps daily to ensure no nails are left in your driveway or lawn.

Material Warranty

We work with trusted manufacturers and certified materials to ensure your manufacturer warranties remain valid through proper installation.
