Repair your wood deck, apply two new coats of stain, then you have more money for other garden improvements.
Deck Repair Decisions:
1. Top Wood plank condition and structure underneath not rotted and soft
2. Clean wood surface, free of BBQ grease, some sand deck … power wash if available
3. Ensure dry and stain coat twice for best look.
Level 2 Deck Repair is going to be expensive. Considerations are
1. Wood prices are up but taking hard look at replacing the entire deck surface.
2. Going to be some structural and rot issues which will add to the budget
3. Ok with the Standard brown wood finish color or going to stain the wood to your own tastes
4. Consider composite decking? If you upgrading from a wood deck you will not have the recommended 12″ stringer spacing needed, pushing you closer towards to a new deck redo!
