Flush bolt Installation/Replacement
A broken or malfunctioning flush bolt on a set of double doors is a critical security risk that is often overlooked. This small component is essential for anchoring the inactive door leaf, creating a solid frame against which the active door can lock. When a flush bolt is bent, misaligned, or fails to engage, it renders the entire locking system vulnerable. The inactive door can be easily pushed open, compromising your home’s security and making the primary lock ineffective. This not only leaves your property exposed but also puts stress on the door hinges and frame, leading to further alignment issues over time.
At A1 Handyman Singapore, we specialize in professional flush bolt installation and replacement, ensuring your double doors are both secure and perfectly aligned. Our skilled technicians have the expertise to precisely mortise and fit new flush bolts into any door material, guaranteeing a seamless look and smooth operation. We use high-quality, durable flush bolts designed for long-lasting performance, restoring the integrity of your doorway. Don’t compromise on security; let our trusted team reinforce your doors with a professional and reliable flush bolt solution.

Benefits of Professional Flush bolt Installation/Replacement
Enhanced Door Security
A professionally installed flush bolt securely anchors the inactive door leaf, preventing it from being forced open and significantly reinforcing the entire doorway against intruders.
Correct Door Alignment
Proper installation ensures the doors remain perfectly aligned. This prevents the primary door from sagging or dragging, ensuring a smooth operation and proper engagement of the main lock.
Seamless Aesthetics
Flush bolts are designed to be concealed. Professional installation means the bolt is mortised cleanly into the door edge, providing a sleek, unobtrusive look that doesn’t interfere with the door’s design.
Effortless Operation
A new, correctly fitted flush bolt is easy to engage and disengage. This eliminates the frustration of struggling with a stiff, bent, or misaligned bolt, providing convenient and reliable use.
Factors to Consider For Flush bolt Installation/Replacement

Bolt Size and Throw Length
The length of the bolt and the distance it extends (throw) must be appropriate for the door and frame. It needs to be long enough to securely engage the jamb or sill without being too long, which would prevent it from retracting fully.
Door Material Compatibility
The type of flush bolt must be suitable for your door material (wood, metal, or composite). The installation method and required mortising will differ, and a professional can select the right hardware for a secure fit.
Manual vs. Automatic Operation
Choose between manual flush bolts, which require a lever to be flipped, and automatic ones that engage when the active door is closed. The choice depends on convenience and the specific application (e.g., fire-rated doors often require automatic bolts).
Finish and Style
Select a flush bolt with a finish (e.g., stainless steel, brass, matte black) that matches your door handles and other hardware. This ensures a cohesive and polished look for your doors.

FAQ
A flush bolt is installed on the inactive leaf of a pair of double doors to secure it in a closed position. This allows the active door to latch and lock properly against it, ensuring the entire doorway is secure and stable.
Signs you need a replacement include the bolt being difficult to slide, bent, or rusted, or if it no longer aligns with the hole in the door frame or floor. A loose or rattling bolt is also a clear indicator that its security is compromised.
Yes, definitely. If the inactive door isn’t held firmly in place by the flush bolt, it can shift or sag. This misalignment can prevent the lock on your active door from engaging correctly, making it difficult or impossible to lock your doors securely.
Yes, flush bolts come in various lengths, materials, and finishes. The two main types are manual (operated by a small lever) and automatic (engages when the active door closes). The best choice depends on your door type, material, and security needs.
Professional installation is highly recommended because it requires precise mortising (cutting a recess) into the door edge for the bolt to sit flush. Incorrect installation can damage the door, lead to misalignment, and compromise the security of the lock.
The cost can vary depending on the type of flush bolt selected and the material of your door (e.g., wood vs. metal). For a transparent and accurate quote, you can send us a photo of your double doors and the existing bolt via WhatsApp.
