King Door and Lock

My door doesn't close all the way. Do I need a new one?
If your door doesn’t close fully, this is problematic not only because it compromises your safety but also because it lets in unwanted drafts that can raise your heating or cooling bill. You don’t necessarily need a completely new door but call us so one of our expert technicians can take a look and provide you with affordable door replacement and repair solutions.
I am having trouble turning the front door lock with my key. Is it time for a new lock?
Several factors can cause a lock to lose its functionality over time. At King Door and Lock, we specialize in both door and door lock services in MD and DC because the two go hand-in-hand. If your door lock is not working properly, our expert technicians can re-key it or change it entirely for you.
I found the perfect front door but it's bigger than the one I currently have. Can I still use it?
Of course you can! Call King Door and Lock today to speak with one of our agents who will walk you through the process of replacing your front door. Different sized doors can be a bit complicated for DIY installation but nothing is too complicated for our door installation experts!
How do I fix the dents in my garage door?
At King Door and Lock, we specialize not only in residential and commercial doors, but also garage door repair in DC and MD. Depending on the severity and quantity of dents, our technicians can either replace the specific section that is dented or we can install a brand new garage door for you!
Do I have to change the locks if I move to a new house or office?
Generally, yes, because you never know who has copies of the key. It’s better to be safe than sorry and at King Door and Lock, we’d be happy to provide you with several options for enhancing your home or business security, and changing or re-keying your residential or commercial door locks is the first step.
