- An aging or damaged deck
- Loose railings or unstable stairs
- A deck that requires constant maintenance
- Limited access between the home and backyard
- Poor traffic flow

Frequently asked questions
What types of decks do you build?
Deck projects may include composite decks, pressure-treated wood decks, ground-level decks, elevated decks, multi-level decks, wraparound decks, deck expansions, replacements, and custom outdoor living spaces. The appropriate design depends on the home, property, intended use, and project requirements.
Which is better: composite or wood decking?
The best material depends on your priorities. Composite decking is often selected for reduced maintenance and consistent appearance. Wood offers a traditional appearance and can generally be stained or refinished, but requires more ongoing maintenance. Material cost, exposure, surface temperature, appearance, lifespan, and maintenance should all be considered.
Can you replace my existing deck?
Yes. An existing deck can be removed and rebuilt based on the new layout, materials, structural requirements, and project goals. The condition of the home connection, footings, framing, and surrounding property should be evaluated before determining the scope.
Can you expand my current deck?
A deck may be expanded when the existing structure and property conditions allow it. The current framing, supports, footings, connections, layout, materials, and applicable requirements need to be reviewed first.
Can you build a multi-level deck?
Multi-level decks can create separate outdoor zones and provide access to different elevations of the home or property. The design must consider structure, stairs, railings, traffic flow, and available space.
Do you install deck railings and stairs?
Railings, guards, stairs, and landings can be included as part of a new deck, replacement, expansion, or approved improvement project.
Can you add a pergola or shade structure?
Pergolas and other shade structures may be included depending on the deck design, structural requirements, property, and project scope. Covered roof structures generally involve additional engineering, foundations, drainage, and permitting considerations.
Do you offer free estimates?
Yes. Fill out the form or call us at (781) 600-2622 and we will set up a visit to see your space and prepare a free estimate.
Do you take care of permits?
Yes. We handle the permits, inspections and approvals your town requires, so you do not have to manage the paperwork.
