Other Replacement in Darlington, SC 29540

“Quality Service Co is AWESOME!
We had a leaking kitchen faucet. Called QSC on a Wednesday afternoon.
Clyde and Mike were here to very next morning to replace faucet set.
Both Clyde and Mike very professional. Did not have to explain what needed
to be done. Old faucet set out and new one in, within a matter of minutes.
Quality Service prices are very, very reasonable.
