Decks we build in Medford
Medford's housing stock runs the full range of Greater Boston history. In the Hillside and West Medford neighborhoods, we're often attaching decks to 1920s–1940s Colonials and Capes with rim joists that have seen a century of New England winters — ledger prep matters here more than on a newer house. In Wellington and the condo developments near the Mystic River, we build smaller urban decks and roof decks where every square foot is counted and railing lines matter visually.
The Mystic River corridor and the lower-lying streets near Medford Square sit on softer, higher-moisture soil than the rest of town. Footings here can require going deeper than the 48-inch Massachusetts minimum to find bearing on undisturbed material. We check at the site walk and don't guess — a deck that heaves after one winter is a deck that gets rebuilt.
Hillside and the ridge neighborhoods above the Fellsway are the opposite: we're often cutting into ledge or working on sloped lots where the deck frame has to carry stair runs down to a terraced yard. We've built plenty of these and they come out looking intentional — three-sided wraps, double stair runs, built-in benches on the long side.
Permits and inspections at Medford City Hall
Deck permits in Medford are handled by the Building Department at Medford City Hall, 85 George P. Hassett Drive. The city processes most residential deck permits within a week or two of a complete submission, which includes stamped plans or a plot plan showing setbacks, a framing diagram, and the Massachusetts State Building Code 780 CMR data on footings and materials.
We handle the full permit application for every Medford deck we build. That includes the sketch, the material spec sheet, the plot plan if it's required, and coordinating the three standard inspections: footings before pour, framing before decking goes down, and final after railings and stairs are complete.
For homes in the Medford Hillside Historic District or any property subject to local historic review, additional approval is required. We've been through that process and can tell you upfront whether your project triggers it based on your address and what side of the house the deck is going on.
What makes a Medford deck different
Two things matter in Medford that don't matter as much elsewhere: freeze-thaw cycling in the valley neighborhoods, and visual continuity with the housing style. A Victorian or Colonial Revival on Salem Street deserves a railing profile that respects the house — square pickets, flat-top balusters, white or dark stain to match trim. We'll push back if you ask for something that fights the architecture.
Medford also has a lot of narrow driveways and tight side yards. Material deliveries have to be scheduled. On many of our Medford jobs we end up stacking lumber in the street with a permit from DPW for a day or two during framing. We handle that permit; you don't need to worry about it.
Materials we use on Medford decks
Material selection is one of the biggest decisions on any deck project. The three main options we build with in Medford:
- Pressure-treated pine. The most affordable path to a full deck — typically $30–45 per square foot installed. Needs stain or seal every 1–2 years to prevent gray-out. Properly maintained PT lasts 15–20 years. Good for budget-conscious builds or utility decks.
- Composite decking (TimberTech, Trex, Fiberon). $50–75 per square foot installed. Essentially maintenance-free — no staining, no sealing, no sanding. Resists rot, insects, and UV fade. 25-year warranties standard.
- Cedar or PVC (Azek). Cedar for a natural wood look with better rot resistance than PT. PVC for a wood-grain product that never rots and stays cool underfoot. $65–90 per square foot installed. The finish quality is noticeably better on both.
Underneath all three, we frame with kiln-dried pressure-treated southern yellow pine and galvanized or stainless hardware. Hardware upgrade to stainless is standard practice on any Medford deck within a few hundred yards of saltwater or in a damp microclimate.
How we actually build it, start to finish
Every project starts with a site walk, not a phone quote. We measure the house wall, check for existing footings, assess grade, decide where the ledger ties in, and talk through what you actually want the deck to do. From there:
- Design and material selection. We put together a plan showing dimensions, framing, railing style, and material. You sign off before we spend time on permits.
- Permit submission. We prepare the plot plan, framing diagram, and material spec, and file at the Medford building department.
- Footings. Below Massachusetts frost line (48 inches minimum), with a footing inspection before pour.
- Framing. Ledger with proper flashing, beams, joists, blocking. Framing inspection before decking goes down.
- Decking, railings, stairs. Boards installed with concealed fasteners (composite) or face-screwed (PT), stair stringers cut, railings assembled and secured.
- Final inspection and walk-through. You and the inspector both sign off.
A standard 16×14 deck with no complications runs seven to ten working days from ledger to final board, plus permit lead time at the front.
