Deck Construction & Repair
Decks built to code, engineered for real New England freeze-thaw cycles.
Decks Done Right for New England Weather
A deck that isn’t engineered for frost heave and proper ledger flashing will loosen, rot, or fail within a few seasons. FortExteriors Systems builds new pressure-treated, composite, and PVC decks on properly sized footings below the frost line, with code-compliant railings, ledger flashing, and joist hardware — plus repair and resurfacing for existing decks.
Materials & Systems We Install
- Pressure-treated lumber framing
- Composite decking (Trex, TimberTech)
- PVC decking (AZEK)
- Cable, aluminum, and composite railing systems
- Concrete frost-line footings
- Stainless steel fasteners & joist hardware
What Sets Our Decks Work Apart
Frost-line footings
Footings are dug and poured below Massachusetts frost depth so the deck doesn’t heave or shift over winter.
Composite & PVC decking options
Low-maintenance Trex, TimberTech, and AZEK decking that won’t splinter, warp, or need re-staining.
Code-compliant railings & stairs
Railing height, baluster spacing, and stair stringers built to current Massachusetts building code.
Proper ledger board flashing
The #1 cause of deck collapse is a poorly flashed, poorly fastened ledger board — we flash and bolt every ledger to code.
How a Decks Project Works
-
Design consultation
We discuss size, decking material, railing style, and how the deck will be used before drawing plans.
-
Permitting & engineering
We pull the required town permit and handle footing/structural engineering sign-off where needed.
-
Footings & framing
Footings are poured below frost line, and pressure-treated framing is installed with proper joist hardware.
-
Decking, railing & final inspection
Decking and railings are installed, and the project passes local building inspection before we call it done.

Decks Questions, Answered
Do I need a permit to build a deck in Massachusetts?
Almost always, yes. Permit requirements vary by town, and we handle the application and inspection process as part of every deck build.
Composite or pressure-treated wood — which should I choose?
Pressure-treated wood costs less upfront but needs regular staining/sealing. Composite and PVC decking cost more initially but need little to no maintenance and resist rot, splintering, and fading.
How do you keep a deck from heaving in winter?
Footings are dug and poured below the Massachusetts frost line (typically 42-48 inches), which keeps the structure stable through freeze-thaw cycles.
Can you repair an existing deck instead of rebuilding?
Often, yes — we can replace rotted ledger boards, resurface with composite decking over sound framing, or rebuild just the railings and stairs.
