If there are specific location identifiers like your name/address or GPS data in the image EXIF, you can likely have them removed for privacy/security reasons (could provide good pointers for burglars), and the contractors would be unlikely to say "no" to such a request which reasonably protects an interest of yours.
If there are copyrightable pieces of artwork depicted (but those, if any are even likely in your jurisdiction, are most likely attributable to the landscaping contractor themselves), there may be separate claims by the parties holding the copyright.
If the photographs have been taken from your private ground by an independent photographer, you'd have some point of arguing trespassing (but that would allow for pressing penalties but not magically cause the photographs to change ownership). But if they have been taken in the course of their normal work access, you'd have rather dim chances of being successful with that kind of argument.
At any rate, try the legal StackExchange.
