C-Mac Development | Trusted Fence Builders in O'Fallon, MO

Freeze-thaw cycles in O'Fallon cause the ground to expand and contract, pushing fence posts upward and loosening them. This can lead to leaning or unstable sections. C-Mac Development addresses this by excavating the affected post, setting it in concrete below the frost line, and backfilling with gravel for drainage. For severe cases, we may recommend replacing the post and installing a new concrete footing to ensure long-term stability.

Signs your deck may need repair include rotting wood, loose railings, cracked boards, or nails popping up. If the structural beams or joists are compromised, or if the deck sways when walked on, replacement may be necessary. C-Mac Development can inspect your deck and recommend either targeted repairs—like replacing individual boards or reinforcing connections—or a full replacement using weather-resistant materials suited for our local climate.

Yes, we offer weatherproofing services for fences and gates. In O'Fallon, moisture and UV exposure can cause wood to crack, warp, or rot over time. We apply high-quality sealants or stains that protect against rain, snow, and sun. For automatic gates, we also check and lubricate moving parts to prevent rust and ensure smooth operation. Regular weatherproofing can extend the life of your fence or gate significantly.
