Alan Adamson's side are 180 minutes away from promotion to Scotland's second tier after their play-off, semi-final success against Arbroath.
They host Second Division rivals Airdrie United in the final first leg tomorrow night before heading to Lanarkshire on Sunday.
And the 25-year-old intends to ensure it is his side that make the step up. The defender, who lives in Clydebank, said: "It would be great for me to win promotion with Dumbarton.
"I had four years with Stranraer and it felt like every game I played was an away game.
"I am 10 minutes from the stadium now. It is a great place to play and it would mean a lot to help get them promoted.
"We are just two games away from the First Division, so it is a great opportunity."
Adamson's men drew 0-0 in Angus on Saturday after winning their home leg 2-1. Nicoll added: "It was a great result for us at Arbroath.
"After the start we had to the season, it was going to take something special for us to get to where we are now.
"We went on a great run in the middle of season and got ourselves up the league. There was a great atmosphere in the changing room at that time.
"We had a really good winning spirit and we started to believe we could get promoted.
"We know what to expect against Airdrie. They are a good side and we will have to be at our best if we are to win over the two games and clinch a place in the First Division."
