Company Profile
Mechanical Infusion LLC started in 2019 as a welding company in Lithonia, GA, serving homeowners and businesses with mig, stick, and tig welding. In 2020, we expanded to include woodwork, fence and gate services, and custom metal fabrication. Our approach is simple: every task—whether welding a gate or staining a fence—is done with the same care as if working for family. We understand local homeowners deal with fence panels damaged by storms and posts leaning after heavy rain. That’s why we focus on proper footing and durable materials to withstand Georgia’s weather. From the neighborhoods near Stonecrest Mall to properties along Panola Road, we help residents keep their fences secure and gates operating smoothly. Our services include fence and gate installation, repair, painting, weatherproofing, and automatic gate systems. We also handle custom metalwork for railings, stairs, and structural welding. What drives us is seeing our customers satisfied with work that lasts. Located in Lithonia, we’re close to Arabia Mountain and the Lithonia Historic District, ready to serve the community with honest, reliable craftsmanship.
Frequently Asked Questions
Why are my fence posts leaning after a big rain?
In Lithonia, heavy rain can soften the soil, causing fence posts to shift if they weren’t set with proper drainage or deep enough footings. We solve this by digging below the frost line, using gravel for drainage, and setting posts in concrete. If your posts are already leaning, we can reset them or replace them with stronger anchors.
Do you offer automatic gate installation for driveways?
Yes, we install automatic gates for residential driveways. We work with swing and slide gates, adding motors, sensors, and keypads. We also repair existing automatic gates if the motor or wiring fails. Our team ensures the gate operates smoothly and safely.
What types of metal fabrication do you do besides gates?
We do custom metal fabrication for railings, staircases, awnings, and structural supports. Using mig, stick, and tig welding, we can create pieces from steel, aluminum, or stainless steel. Whether you need a handrail for your porch or a custom fire pit, we can build it to your specifications.
