Built for your property
A deck plan that starts with the house and yard
Chelmsford includes established neighborhoods, wooded lots and homes with very different grades. A useful deck must respond to those conditions. During the site visit, we look at the door location, height above grade, everyday path to the yard, available space and access for construction. We also listen to how you expect to use the deck, whether that means a compact landing, room for outdoor meals or stairs that connect cleanly to a lawn.
FJ Global builds custom decks in traditional wood and low-maintenance composite. Material is only one part of the decision. Board direction, railing, stairs, post locations and the shape of the frame all affect how the completed space works. Fredy Justino owns and operates the company, so the first conversation stays connected to the proposed build.


New England details
Structure, drainage and weather belong in the plan
Deck construction in Chelmsford has to account for seasonal freezing, snow and repeated wet-dry cycles. Footings need to follow the approved design and local frost-depth requirements. The ledger and flashing deserve close attention because they protect the connection at the house. Beams, joists, stairs and railings must work together as a complete structure rather than a collection of surface upgrades.
A permit may be required when a deck is new, enlarged or structurally replaced. Review happens through the local building department, and requirements can vary with the property and scope. Setbacks, plans and inspections are worth discussing early, before materials are ordered. We define those construction questions during estimating so the written proposal has a clear basis.
Repair or replace
Start with the condition of the existing deck
Loose boards do not automatically reveal what is happening below. We look at accessible framing, posts, stairs, railings and the connection to the home before recommending a path. A limited repair can make sense when the affected area is defined and the supporting structure remains suitable. Widespread deterioration, movement or an outdated layout may point toward replacement. If a rebuild is the practical choice, it also creates an opportunity to improve stair placement, circulation or material selection.
Our deck service extends beyond Chelmsford to nearby Lowell, Westford, Billerica, Tyngsborough and Nashua. The property visit confirms both the work and the location before a proposal is prepared.
