THIEVES stole tools and other items totalling hundreds of pounds after raiding sheds and garages in Ash.
Five break-ins were reported in a two-day period, with police warning residents to be on their guard for more raids.
A Surrey police spokeswoman said they should consider taking simple security measures to protect their property.
"Installing a noisy shed alarm and putting security marks on expensive items may help to deter the thieves," she said.
"Shed alarms, which are easy to install and cost around £20 to install, can be purchased at most DIY stores."
The spokeswoman added that strong and properly fitted padlocks should also be fitted to shed doors.
"Many sheds contain a large number of valuable tools and other items," she said. "But in many cases only a cheap padlock is fitted to the door."
One of the raids was in Burrwood Gardens, Ash Vale, when two men's mountain bikes, together worth £400, were stolen.
Gardening equipment and tools valued at £580 were stolen from a shed in Lincoln Close, and similar items worth £800 were taken from a garage in Ash Hill Road.
Alcohol and a petrol lawnmower worth £125 were stolen from an outbuilding in Derwent Avenue, and four mountain bikes were taken from a garage in Lakeside Road.
All the raids took place between September 6 and 8, and police have appealed for information from anyone who saw people acting suspiciously in the area during those three days.
