J&G Fast Construction | Best Fence Installation in Northfield, NJ

The main cause in Northfield is the combination of high humidity and sandy soil that retains moisture under decks. Without proper airflow or drainage, trapped moisture accelerates rot. J&G Fast Construction prevents this by installing adequate joist spacing, using moisture-resistant fasteners, and applying a quality sealant. For existing decks, we recommend annual inspections to catch early signs of decay before they spread.

Yes, leaning posts often signal that the concrete base has shifted due to loose, sandy soil or water pooling. J&G Fast Construction can reinforce or replace the affected posts, digging deeper footings set below the frost line and using gravel for better drainage. We also check the entire fence line to make sure the rest of your fence stays straight and secure.

If you see widespread splintering, wobbly railings, or soft spots when you walk, especially near the ground contact area, replacement is often more cost-effective than ongoing repairs. J&G Fast Construction offers a free on-site inspection to look at ledger boards, joists, and footings. If the structural framework is sound, we can often replace just the decking and railings. If not, we'll recommend a full replacement that meets current code.
