What door closer installation involves
Oil leaking from a door closer may mean its internal seal has failed.
As fluid escapes, the unit can lose control of the door, leaving it to slam or stop short of the latch. In Upper Darby, we install a replacement when a leaking unit can no longer control the closing movement. An adjustment may be an option when there is no leak and the problem comes from the settings. We look at how the unit works before recommending either choice, so you know why one makes sense.
An entrance that feels heavy to open presents a different problem from one that will not stay shut. We adjust the closing action and final movement with both concerns in mind, rather than simply increasing the force. Wind can catch an entrance while it is open and put extra strain on the hardware, so exposure matters when choosing a suitable closer. In Upper Darby, we take those conditions into account when fitting a unit, then check that the entrance closes and latches on its own without making it unnecessarily hard for you to push open.
What we ask when you call
When you call, we will ask whether the door is inside or outside, what it is made of, and whether it swings inward or outward.
Those details help us identify a suitable closer and where it could be mounted. Tell us if it slams, stops short of latching, feels heavy to open, or gets caught by the wind. Each symptom points us toward a different adjustment or equipment choice. If an existing unit is leaking oil, mention that too, since it may need replacement rather than adjustment.
Have the lock details ready, including whether you use a key or a push bar and whether the latch catches when you close the door by hand. That tells us whether the difficulty may involve more than the closing mechanism. A photo of the entrance and any existing hardware is useful if you can provide one, but a description is fine if you cannot. We may also ask about markings on the current unit to identify a compatible replacement.
Once we reach the business door
When you have a door that slams shut, we start by watching how it moves and whether it catches in the latch.
We look at the existing closer, how it is attached and whether oil is leaking, then consider the door's weight and whether wind is pushing it. A loose attachment or an adjustment that no longer suits the opening may be part of the problem. We explain what we find before starting, including whether the existing unit is suitable for adjustment or needs replacement.
If the closer is leaking, replacing it is usually the practical choice because the oil controls its movement. For a new installation, we explain the options that fit the opening and how the effort needed to open it relates to the force needed to latch. Wind can affect that balance, so a setting that feels easy to open may not always bring it fully shut. After the work, we open the door with you and watch it close and latch. We also check how it feels to open, making adjustments where needed.

Local to Upper Darby
In Drexel Hill, you may pull your door shut and find that it rests against the frame without latching.
The key may still turn, but that alone does not mean the door is secure. Check that the latch has caught before relying on the lock. A closer that brings the door all the way in may make a difference, though alignment matters too.
For the same problem in Upper Darby, adjustment may be an option if the closer is in sound condition. If oil is leaking from it, replacement is usually the practical choice because an adjustment will not restore the lost fluid. Opening force matters too: a unit that pulls too hard can make the door difficult to open, while wind can keep it from reaching the frame.
Keeping it working
After installation, watch how the door closes and whether it latches without a push.
If wind catches it, keep a hand on the handle as it shuts, with your fingers clear of the edge. Avoid wedging it open, which can put strain on the closer. If you need it to stay open, use a hold open feature only if one is fitted.
Oil on the closer or on the floor beneath it can be a sign of an internal leak. Do not add lubricant or turn the adjustment screws to compensate. Call us again if you notice a leak, if the door starts slamming or fails to latch, or if opening it becomes unusually difficult. We can check whether an adjustment is appropriate or whether the unit needs replacement.
Your questions, answered
Will my existing key still work after you install a closing device at my entrance?
Yes, your existing key should still operate the lock if that hardware stays in place. A closer controls movement, not the key cylinder. Closing and locking are separate functions: a spring latch may catch when the door shuts, while a deadbolt still needs to be locked separately.
Can the closing device be hidden on my glass storefront door in Upper Darby?
It may be possible, but a glass storefront needs compatible mounting space for a concealed model. Some designs sit inside the top rail or floor, while others attach visibly to the surface. Standard hardware cannot be fastened directly to the glass, so the construction and available space determine which style is practical.
Do both sides of my double entrance need their own closing devices?
If both sides need to close on their own, each one generally needs its own closer. The two sides do not share closing force across the opening. If one side normally stays secured and only the other is used, a single unit on the working side may be enough.
