WHAT OUR CUSTOMERS SAY

Drain Cleaning Maintenance in Newark, DE 19711

12-09-25

“Dennis and his trainee from Joseph Frederick & Sons were absolutely outstanding. They not only cleared the blockage but also took extra steps to make sure the entire line was fully clean and running properly.

Both were extremely professional, courteous, and very personable throughout the entire visit. They explained what they were doing, worked efficiently, and made sure everything was in perfect working order before leaving.

Truly exceptional service — I couldn’t recommend Dennis and his trainee more highly. Thank you for going above and beyond!”
