Deck Building & Repair in Chelsea

Ask for photos and addresses of decks built 3+ years ago (new decks all look good), proof of insurance, and whether they or a subcontractor do the footings. In Chelsea, also check any licence or registration your local rules require for structural outdoor work before signing.

A simple ground-level deck takes 2-4 days. An elevated deck with footings, stairs and balustrades typically takes 1-2 weeks, plus any permit or inspection lead time before work can start.

A complete quote lists demolition/removal of any old structure, footings, framing timber and spans, board type and grade, fixings (hidden vs face-screwed), balustrades, stairs, waste removal, and whether permit fees and engineering are included. Missing line items are where cheap quotes grow.

Timber is cheaper to install but needs sanding, staining or oiling every 1-3 years. Composite costs 50-100% more upfront but only needs washing. Over 10-15 years the totals often converge, so the decision usually comes down to upfront budget and how much maintenance you will actually do.

Every 12-24 months for oil finishes and 2-4 years for film-forming stains, depending on sun exposure. Re-coating on schedule is the single biggest factor in how long the boards last.

Deck cost is driven by area, height off the ground, and material. Ground-level softwood decks are the cheapest; elevated decks need engineered footings and balustrades, and composite or hardwood boards can double the board cost. Most quotes are priced per square metre or square foot, with stairs, balustrades and lighting as line items.

Remodeling-industry cost-vs-value studies consistently put wood deck additions at roughly 50-65% cost recouped at resale — mid-pack among exterior projects. Composite recoups slightly less because of the higher upfront cost.
