Best door pros near Harlem, NY

Before attempting to reinforce an apartment door, speak to the property owner. If the door hasn’t been updated in a while, the landlord may offer to cover the cost of a professional locksmith or your expense of this security update. Rekeying a door can be a costly and lengthy affair, so try low-impact, inexpensive tricks—like installing a deadlock or a door jammer—first.

While not strictly required, it is highly recommended to shim both sides of a door. Shimming both sides allows you to make minor adjustments for wall framing that isn't perfectly plumb, ensuring the door is level and hangs evenly. This practice helps the door swing open and close smoothly, reduces the chances of the frame warping, and can be used to center the door within the wall opening. If you are working alone, you may find it easier to remove the door slab to lighten the weight while supporting the frame and inserting the shims. With two people, the process is generally faster and easier, whether the slab is left in place or not.

If your specific sliding glass door model is out of stock or no longer being built, it may still be best to contact the original manufacturer or installer. They can suggest a comparable replacement that is similar in size, avoiding more expensive repairs to retrofit a new door to an older opening. 

To build a standard size, six-panel door yourself, you’ll need four 2-foot by 6-foot boards, one 2-foot by 8-foot or 2-foot by 10-foot board, and a sheet of 3/4-inch, paint-grade plywood. The 2-foot by 6-foot boards will serve as your stiles, top rail, and horizontal and vertical mullions, and the wider board will serve as the bottom rail, which is usually wider than the other horizontal pieces. The plywood will serve as the panels, but you’ll need around five 1-foot by 6-foot boards to make your own panels if you want to stain the door rather than paint it.
