Electrical Maintenance in Wilmington, DE 19804

“I’m thankful to have Jos. Frederick & Sons involved with all necessary things I require at times – all is explained and they work well doing whatever is necessary. I have had them working on all items I require – under plumbing, electrical, replacement of items – Andrew and Cameron worked well and explained all during this job of today. Thank you
