I had a great experience with Nan Construction with new door lock installation. They were quick to respond to my request and accommodated my request to install lock on the same day.
They also arrived on time, installed the lock quickly, provided clear explanation on operating the keypad.
I am glad to have used their hassle free service and I highly recommend them.

I've got locked out of my house. With nan constructions I've got back inside in 45 minutes from my call. You cannot do it faster than that! Tech came in 10-15 mins. He explained to me fasteat and least damaging way to get in, opened four locks and saved my day. Great experience!

I needed to find a locksmith to change an existing door lever to one with a key so it could be locked, but match the style of all the other doors in the apartment. I'm glad that I contacted NAN Construction because they took care of this situation in a day, quickly and efficiently. Their office sent me a photo of the replacement door lever so I could approve what the technician was going to bring to the job. He showed up on time, and did the change-over to the new lockable door lever very quickly.
I would hire this company again.

We had to replace the locks. Nan construction was responsive and fixed the issue. They even identified an additional issue around doors and fixed it free of charge. Overall I would not hesitate to get them for any of my lock needs
