DECKS · CORNWALL, NY
Decks in {Cornwall.}
Thunder Pro Construction provides licensed decks in Cornwall, NY. Family-owned since 2020 — free written estimates and storm-response support across Orange County.
Why hire us for decks in Cornwall?
Custom decks built from pressure-treated lumber, cedar, composite and PVC. Footings to spec, joist spacing to code, and railings that pass every inspection on the first walk. We also rebuild rotten decks the right way — replace the framing, not just the boards.
What areas of Cornwall do you serve?
Cornwall combines river views, wooded lots and established neighborhoods — all of which need exterior systems built for moisture, wind and heavy winter weather. We serve Cornwall homeowners with full roofing, siding and storm repair crews.

QUESTIONS
Common Decks questions in Cornwall, NY
More questions? Call (845) 234-9871 or request an estimate — we don't believe in pressure sales.
Composite or wood?
Composite costs more upfront but needs no staining and carries 25–30 year fade warranties. Pressure-treated wood is economical; we recommend composite for low maintenance.
How long does a deck build take?
Typical single-level deck: 1–2 weeks including footing cure time and inspections. Multi-level or composite builds may run 2–3 weeks.
Do you pull permits?
Yes. Decks over a certain height and all structural builds require permits in Orange County. We handle drawings, permits, and inspections.
Can you rebuild over old framing?
Only if the ledger, joists, and footings pass inspection. About 30% of re-deck calls need partial framing replacement — we tell you before we start.
