Hanworth Villa may have to get the workmen back in one final time before they are allowed promotion to the Combined Counties Premier.
The Villains finished second in Division One last season but were denied promotion as their ground was deemed not suitable for the top flight.
Since then, Rectory Meadow has undergone a transformation, with floodlights and a new stand put in.
It was announced that this would give Villa's ground the necessary grading it was lacking before, and a similar league placing (they are currently second) would see them up.
But the league's ground inspection sub-committee this week said new fences would have to be put up before the club can progress.
The report stated: "Following the visit to Hanworth Villa FC, the FA Technical Panel had stated, contrary to the understanding at the time, that a fence around the whole complex but within all undergrowth, may be acceptable for granting a Grade F.
"It was the unanimous view of the inspection sub-committee though, that due to the large area in question, which was public park land, this was unacceptable to the league as the ground would fail to meet the initial requirement of the relevant ground grading document - 'the ground must give an overall appearance and impression of being a football ground suitable for the National League System.'
"It was resolved unanimously, therefore, that prior to acceptance for promotion, Hanworth Villa FC would be required to erect a fence around those two sides of their ground identified on previous visits.
"It was hoped the club would be able to comply with this as they have made tremendous strides, and it did seem that the cost of a fence around just two sides would be infinitely cheaper than the cost of a fence around the whole complex .
"The club would be advised of this resolution as swiftly as possible in case they wished to appeal to the FA against the league's decision."
Villa's Combined Counties One derby with CB Hounslow United fell victim to the weather on Saturday, while Feltham saw their game postponed for the second week in a row.
It was a similar story in the Premier, where Bedfont Green's home game with Raynes Park Vale and Bedfont's trip to Chertsey both bit the dust.
Weather permitting, Bedfont will host Horley Town on Saturday, while Bedfont Green have a top-of-the-table clash at Epsom & Ewell.
The following Saturday sees a number of derbies, with Bedfont hosting Bedfont Green, Feltham visiting Hanworth Villa and CB Hounslow Utd travelling to Staines Lammas.
