A Closer Look at Door Chain Installation
Installing a lock correctly is about far more than screwing on a piece of hardware. The bore has to be the right size, the backset has to match, the strike must align with the bolt, and the whole assembly has to sit flush so the door closes and locks without a fight. Small mistakes here are why so many doors 'stick' or fail to lock a year later.
We take the time to measure, prep, and align every installation properly, then cycle the lock repeatedly to confirm it operates smoothly from both sides. The result is hardware that not only looks right but keeps working reliably for years, not months.
