Chris Westwood headed the only goal of the game in first-half stoppage-time, but Chairboys goalkeeper Nikki Bull produced a string of fine saves to keep the Bees at bay.
"Our goalkeeper was excellent, but he's a good goalkeeper," said Waddock. "Again he's been able to keep a clean sheet with a number of good saves. We know how good he is and we're delighted to have him at our club."
Waddock added: "It was a good header from Chris from the set play and we couldn't have scored at a better time.
"We will take wins any way they come at the moment. We wanted to win the game and pick-up the three points and we've done enough to achieve that.
"You don't always play well, sometimes you play really well and don't get anything and sometimes you are below average and you get the three points and the win."
