About Us...

Advance Trade is a commercial and industrial electrical contractor based in Mountville, PA and owned by Sean Welling.

Since 2004, Advance Trade has grown into a nationwide contractor with more than 30 full-time employees to serve your needs.

We believe the strength of our business is our service. That's why we don't use sub-contractors to complete our installations. You'll work directly with the owner and our professional electricians who will help you improve the efficiency of your lighting and save you money!

Advance Trade is continuing to expand and will soon open several satellite offices throughout the United States. We will also be working on projects in Canada in the coming year.
