Deck Construction Best Practices
Pressure-treated Lumber
Footings set below local frost depth prevent movement and heaving.
Ledger Flashing
Proper flashing and water-resistant barriers prevent rot where deck meets house.
Ventilation and Material Spacing
Allow for drainage and thermal movement especially with composite materials.
Inspection of Existing Structure
Old homes require thorough ledger and rim board examination before tying in a new deck.
Materials and Finish Option
Pressure-treated Lumber:
Cost-effective and traditional choice.

FAQs
How long will a new deck last?
Properly built wood decks with regular maintenance can last 15–25 years; composite decks may last 25+ years with minimal upkeep.
Do you replace old ledgers?
Yes. Replacing a failing ledger and installing proper flashing is a common and important deck repair that restores safety.
Are footings required to be below frost depth?
Yes. In our area, footings must extend below frost depth to prevent frost heave; we size footings accordingly.
