| NumeralQ scope | Planning baseline | Included scope and limits |
|---|---|---|
| Composite deck | View current estimate | Frame, boards, ledger, footings, and hardware; excludes railings, stairs, and permits. |
| Blended deck and patio | View current estimate | Blended composite-deck and concrete-patio project; excludes cover structures. Not a material-by-material comparison. |
These first-party planning-model baselines follow the published methodology. They are not contractor bids, local observations, or lifecycle-cost estimates. The project does not retain a verified concrete-only or pressure-treated-wood comparison for this guide.
Questions to Resolve Before Choosing
- Grade and drainage: Check slope, runoff, excavation, retaining needs, and access for equipment.
- Structure and attachment: A raised or attached deck has different framing and inspection requirements than a slab at grade.
- Use and maintenance: Consider privacy, shade, accessibility, surface comfort, cleaning, and product-specific care.
- Scope: List demolition, site preparation, structure, surface, stairs or edges, disposal, and permits before comparing written bids.
- Confirm applicable building, zoning, drainage, and permit requirements with the local authority.
- Ask each bidder to identify assumptions and exclusions; compare like-for-like scope rather than headline totals.
Climate and Site Conditions
Weather exposure, drainage, soil, shade, and product specifications can affect design and maintenance. This guide does not assign regional service lives or claim that one material is best in every climate. Follow the selected product's installation guidance and have site-specific structural or drainage questions assessed by a qualified professional.
Frequently Asked Questions
Is a concrete patio cheaper than a wood deck?
There is no supported universal price comparison in this guide. Compare written bids for the same site preparation, structure, finish, disposal, and included work.
Do I need a permit for a deck or concrete patio?
Requirements vary by jurisdiction and project scope. Check with the local building department before work begins, and review any applicable HOA requirements.
Can I pour concrete over an existing concrete patio?
That depends on the slab's condition and the overlay system. Have a qualified concrete professional assess the surface and follow the selected product's installation instructions.
