Saints captain Stephen McGinn heaped praise on the travelling support and confessed their support was important as St Mirren picked up three points.
More than 700 Buddies supporters packed out the away end at the YOUR Radio 103FM stadium to see Saints win away against Sons for the first time since 1996.
The skipper spoke to stmirren.com after goals from Gavin Reilly and John Sutton saw Saints overcome Dumbarton 2-0 on Saturday.
He was pleased to give back to fans who have backed them in big numbers this season and said their support helped the team over the line on Saturday.
Full credit to them," he said of the fans. "They aren't daft - they know how tough a game it is here.
"They've probably been down here and seen some horror performances so we are glad to repay them.
"There was a sticky spell at the start of the second half and they realised that, found their voices and dragged us through again. We hope that relationship keeps getting stronger.
"A couple of times there have been big following this season and we've let them down so glad to repay them today.
"It's no secret this has been a really tough place to come for this club. Dumbarton ask questions of you, they make you defend and it's not an easy place to play.
"Physically it's always really tough to get through the game here. It was so pleasing to get three points and a clean sheet."
The win saw Saints close out the first set of fixtures on top of the league with 21 points - matching the target they set before the start of the season.
McGinn admitted that it was a demanding target they had set, but he knew the side was more than capable of achieving it.
"We know it's only one quarter of the job done. It was an ambitious target but we looked at the fixtures and thought why not?
"We're disappointed with the two games we've lost, but as a quarter 21 points was an ambitious target and we are absolutely delighted to reach it.
"The group we've had since January - the core of us that has played in a lot of games - are used to winning. It's a great habit.
"We know when we are good that we are really good. I think that's why we had such an ambition target because we would feel like we had let ourselves down if we had it any lower."
Another positive for Saints was the return of Kyle Magennis who made his long awaited comeback to the first team as a substitute on 84 minutes.
The midfielder has been out since an injury against Dundee in a pre-season friendly in July.
Despite being just 19 years of age, McGinn admits he's such an asset to the side and will have a big role to play now he is back.
It's amazing to have him back," he said. "I think you could tell from the reaction of the crowd.
"I almost wanted to cheer myself when he came on because, although he is so young, he was a huge player for us last season and he'll be a huge player for us this season."
