Have you noticed your door slamming shut when it used to close smoothly? Why is the door slamming? Why isn’t the door latching shut like it used to? 

The answer could be simply a change in the season or weather!  Door closers (the mechanical piece mostly found at the top corner of the door) should be checked in every season and adjusted as the weather changes.

Why does the weather affect your door closer? Inside of the door closer is hydraulic fluid. The change in cold or hot weather can can affect the hydraulic fluid and lead to a loss of pressure. 

This can easily be adjusted on the closer itself by adjusting the following areas. 

Most Door Closers have a few simple adjustments:
1. Back Check (last 5-15 degrees of the door opening)
2. Swing Speed (from an open position to the last 5-15 degrees during closing
3. Latching Speed (last 5-15 degrees of the door closing)
4. Spring Strength (how much power or resistance the door closer has)

Tools Needed:
1. Allen Wrench
2. Screw Driver
