Ashford United must find £220,000 after The F.A. told them their 3G pitch needs a considerable amount of work to be passed as playable for 2017/18.
The Homelands surface, which also host Canterbury United home games, requires a radical overhaul to pass an inspection.
Owners Minotaur are facing up to the huge cost as the Southern Counties East League leaders are told they have to have the pitch in order by the end of May.
Minotaur’s Glyn Jones said: “The deterioration of the pitch, following its original installation was deemed unsuitable.
“We have instructed a team of experts to inspect the pitch.
“The main problem is the irregularity of the playing surface, a result of issues with the sub base foundations having not been laid properly.
“The current estimate is that it will cost £220,000 to pay for essential repairs and rectification in the off season.”
Although the pitch has been removed from The F.A’s list of approved surfaces, both sides will be allowed to play on until the end of the season.
