Letterbox lock replacement in Ottery St Mary

Good to Know

**Junk mail reduction**: Gravity flaps and keyed locks stop people pushing leaflets through. You'll still get addressed post. Put a "No junk mail" sign up as well for best results. **Royal Mail delivery**: Gravity flaps allow post delivery. Keyed locks mean you need to unlock daily or post can't be delivered. Internal cages let post in but lock it securely inside. **Security benefit**: Letterbox locks prevent "fishing" attacks where criminals use tools to reach through and grab keys, unlock doors, or steal post from inside. **Draught reduction**: Proper letterbox seals reduce heat loss and draughts. Brush seals work well but wear over time. Gravity flaps seal better but cost more. **Door compatibility**: Most external doors can take letterbox locks. Measure your opening - standard UK size is 250-260mm wide, 40-45mm high. Odd sizes need custom solutions. **Key types**: Some keyed letterboxes use standard keys, others use unique keys. Consider how many keys you need and whether you want all household members to have access. **Maintenance**: Keep the mechanism clean - dust and debris stop smooth operation. Oil hinges annually. Replace brush seals when they look worn. **Fire safety**: Some buildings require letterbox seals that automatically close in fire conditions. We'll advise if this applies to your property. **Alternative solutions**: If you want to stop junk mail completely, an external post box removes the letterbox issue entirely. We can advise on options.
