Matchlock Contracting: Qualified Electricians Serving Saint Louis 63101

Great question. Saint Louis humidity is tough on outdoor electrical. For any deck, patio, or outdoor addition, we use weatherproof in-use outlet covers ("bubble covers") and specify corrosion-resistant, GFCI-protected outlets rated for wet locations. We also ensure proper grading and placement to minimize water exposure. This is a standard part of our outdoor construction and electrical inspection process to keep your new space safe and functional for years.

Absolutely. This is a very common issue in older Saint Louis homes during renovations. Arc fault circuit interrupters (AFCIs) are crucial for safety but can be sensitive to older wiring or appliances. Our licensed electricians will diagnose the cause—often a shared neutral, a worn appliance, or outdated wiring—and provide a solution. This may include updating the circuit, separating loads, or installing a compatible, modern AFCI breaker, ensuring your new kitchen is both safe and reliably powered.

When building a detached garage, ADU, or any new structure, we design and install a completely new, up-to-code electrical system. This includes a dedicated sub-panel with modern, correctly sized arc fault and GFCI protection for all required circuits. For any outdoor-run conduits and exterior outlets, we use sealed, schedule 80 PVC conduit and commercial-grade, weatherproof fixtures to combat corrosion. This proactive approach during new construction prevents the common local issues before they ever start.
