Questions homeowners ask
- Does a deck need a building permit?
- Many municipalities require a permit once a deck exceeds a set height or area, or when it is attached to the house. Because thresholds differ by municipality, treat every deck as a permit check.
- Is composite decking worth the extra cost?
- Composite raises material cost but lowers annual maintenance. Compare total cost over the years you expect to keep the home, not just the install price.
Typical schedule: 1 to 3 weeks on site, plus permit review. See the full renovation timeline.
