What Goes Into a Professional Door Knob Lock Installation
A clean door knob lock installation is not simply a matter of screwing a new knob into the existing holes. Our technicians begin with a full assessment of the door edge — checking the backset (typically 2-3/8 inch or 2-3/4 inch on most Raleigh-area homes), the cross-bore diameter, the latch bore, and the condition of the existing strike plate pocket in the jamb. On older homes, especially Craftsman-style houses common in Mordecai and Oakwood, door prep dimensions were often non-standard, and the wood around the original mortise pocket may show signs of splitting or wear. Identifying these issues before drilling a single hole saves the door from damage and ensures the finished lock functions smoothly for years.
Once measurements are confirmed, our technician selects the correct hardware — we carry knob lock sets from trusted manufacturers like Schlage and Kwikset in multiple finish options — and performs any necessary bore adjustments with precision hole saws and chisels rather than brute force. The strike plate is recessed properly into the jamb so the latch bolt fully seats when the door closes. Every installation is tested for smooth operation, proper latch engagement, and key function before we consider the job complete. Where possible, we work damage-free, preserving the original door finish and jamb integrity.
