Three gas leaks have been discovered within the estate which rocked Kincaidston last week.
Safety teams investigating the explosion say a survey carried out on the area has uncovered a trio of leaks.
Scottish Gas Networks (SGN) today confirmed they had identified the need for three "minor repairs".
They said all repairs were separate to the blast site which completely wiped out a property in Ayr's Gorse Park and left a family of four seriously injured in hospital.
A mother, aged 47, and her 16-year-old son remain critically ill.
Gas bosses stressed the discovery of the repairs was in no way linked to last week's explosion and said the local supply was "safe to use" for residents.
A number of families who live closest to the blast site are still displaced from their homes as investigating teams continue to probe the incident.
Health and safety officials have yet to determine the exact cause of the blast last Monday which saw hundreds evacuated, with the explosion felt up to four miles away.
SGN said in a statement: "Following localised safety checks last week, we have now completed a safety survey of the whole of the Kincaidston estate.
"From this survey we identified the need for three minor repairs. Two are complete and we’re working on a third now.
"As a result of the safety checks, we can confirm to householders their gas remains safe to use."
