Between scorching July humidity, salt air along the coast, torrential autumn rains, and heavy winter snow accumulation, Massachusetts puts exterior building materials through one of the harshest testing grounds in the country.
If you are planning an exterior overhaul—whether replacing trim, siding, windows, or building a new porch—selecting materials based purely on appearance can lead to premature rotting, peeling paint, and high maintenance costs.
High-Performance Trim & Siding Options Compared
-
Cellular PVC (Azek, Kleer): Highly recommended for ground-level trim, window surrounds, and fascia boards. PVC is completely impervious to rot and insects. While it expands and contracts slightly more with temperature shifts, using proper mechanical fasteners and specialized adhesives creates a lifetime exterior trim package.
-
Fiber Cement Siding (James Hardie): An outstanding choice for home exteriors. Fiber cement combines the authentic texture of traditional wood lap siding with non-combustible, rot-resistant durability. It holds paint three to four times longer than natural wood because it doesn’t absorb moisture.
-
Pre-Primed Western Red Cedar: For historic homes where traditional wood is required by local historic districts, clear cedar remains unmatched. Its natural oils resist decay, but it requires meticulous six-side priming (sealing all cut ends) prior to installation to prevent paint failure.
The Critical Importance of Flashings and Flashing Tape
The highest-grade siding in the world will fail if water gets behind it. True exterior longevity comes down to flashings—the metal and rubberized membranes installed around window openings, door sills, roof-to-wall intersections, and ledger boards.
We take pride in applying multi-layer weather-resistive barriers and custom-bent aluminum flashings on every exterior job we touch. Protecting the structural framing underneath is just as important as perfecting the exterior finish.
