Both men's semifinals turned into long wars of attrition with club captain Lynn Dent acknowledging a lot of tennis had to be played to get a result.
A runner-up in the doubles last year, Michael O'Callahan was a late entry with partner Ben Pilet and they had to play an extra game in the draw to make the semis.
Their luck ran out against Paul Cornish and Martin Sosnowsky, who prevailed in a tight tiebreak 2-6 7-6 (10-4).
Across court from them, Doug Ireton and Paul Rayner eventually saw off Ivon Southon and Craig Davey 6-3 1-6 (10-4).
Ireton and Rayner proved to have the most left in the final, winning 6-3 6-1 although the games were closer than the match score suggests.
The B Grade finals were made up of teams beaten earlier in the qualifiers.
Rachel Cronin and Mary Stobb won the women's while Patrice Maphey and Chris Ferguson took out the men's grade, both games in straight sets.
Next up for the club is the singles championships in a couple of weeks.
