FAQs About Deck Building Services in Lexington, MA

How do you want to use the space?

This is the first question we ask at every consultation. A deck for large-scale entertaining looks different from one built for quiet family evenings or a morning coffee spot. Lexington’s generous lots and established landscaping give us design flexibility that most towns don’t offer — we build around your priorities so the deck matches how you actually live.

Most composite deck projects in Lexington range from $30,000 to $65,000 depending on size, material tier (Trex Select vs. Transcend, TimberTech Pro vs. Prime+), railing style, and features like built-in lighting, benches, or under-deck drainage. Larger multi-level builds with premium finishes on Lexington’s higher-end properties can go beyond that. We provide a detailed written estimate after the on-site consultation.

Yes. The Town of Lexington requires a building permit for most deck construction. We handle the permit application, including structural drawings and site plans, and schedule all required inspections. This is included in the project — you don’t need to deal with Town Hall separately

Most standard deck projects take 1–2 weeks of on-site construction after permits are approved. Larger multi-level builds with extensive features or site work may take 3 weeks. Permit approval in Lexington typically runs 2–4 weeks. We give you a clear timeline at signing.

Both are premium composite brands with excellent warranties. Trex Transcend has a slightly more wood-grain texture; TimberTech Prime+ offers a wider color range at a mid-tier price. Both resist fading, staining, and mold. We carry full sample boards so you can see and feel the difference before choosing.

Yes — and most Lexington homeowners do. Built-in LED riser lights, post cap lights, and under-rail lighting extend usable hours and add ambiance. We also install under-deck drainage systems (so the space below stays dry and usable), built-in benches, planter boxes, and custom railing configurations. These details are planned during design, not added as afterthoughts.

We build the structural frame with pressure-treated lumber on every project — that’s the industry standard. The decking surface (boards, railing, trim) is where you choose between composite and wood. Most Lexington homeowners go composite for the low maintenance and premium appearance, but we can build a full pressure-treated deck if budget is the priority.
