Unexpected problems with the stonework at the Cookham Dean war memorial means restoration works have run over schedule.
The Cookham Parish Council-led project was due to be completed by the end of June. Issues with the pebbling in front of the memorial means that specialists need to reassess the situation.
The council is working closely with the War Memorials Trust and Historic England, both have given grants for the work.
Council chairman Fiona Hewer (Lib Dem, Cookham Rise), said: "The Cookham Dean War Memorial Conservation and Restoration Project is an exciting and important undertaking that will help ensure a strong future for Remembrance in Cookham, and preserve community history.
"Unfortunately, despite detailed preparations with our expert partners, the work has been delayed by some unexpected problems. We are determined to achieve a high quality finish - we want it to grace our village for another 100 years.
"This has meant the site has been inactive while we wait for key investigations to take place, and it has not been possible to complete the work in the 10 weeks we had planned. "Cookham Parish Council apologises for the inconvenience."
