In case th HOA is still looking for contractors to repair the tennis courts, here are two contacts:
1) Justin Givens 832 893 4855 He submitted a quote to the HOA six months ago for +-$12000
2) AAA Court Services 281 723 8250 or 713 271 2055 They just did a nice job on our neighbor's courts in the Laurel Oaks sub-division. You may want to take a five minute ride and look.
Let me know if I can help. G Moe
