Garvey, 27, and Houston, 28, both arrived at The Rec at the start of last season - from London Irish and Colomiers respectively.
Mercer, 25, came through the youth ranks at the Premiership club and graduated through the academy during the 2011-2012 season.
"Matt, Leroy and Guy are all talented players," said head coach Mike Ford.
"They offer different qualities that give us a good variety and strength in depth in the back row.
"They are passionate about the club and committed to what we are trying to achieve here. We're really happy they are staying on and know they'll continue to give their all for us."
