Solid contractor with quality work and fair prices. Responsive with communications.

Nick from Knock Knock did a great job replacing the old hardware on our solid wood front door. We originally had three separate pieces of hardware, and he helped us simplify everything down to a new smart deadbolt and handleset. The job also required filling and covering the opening left behind by the old lock. Nick was very professional, thorough, and worked late to make sure everything was completed properly. The Bondo used to fill the old opening did create a pretty strong smell inside the house for a few hours, but that was temporary and the finished result looks great. We’re very happy with the work and are already considering having Nick come back to help with some additional weather sealing and replacing the door kick plate. Would definitely recommend him!

Tricky job with French Wooden Doors that are very old. Fixed job and then asked if there were any other projects he could help with. Much appreciated seeing if more to do and cleaning up his mess AND double checked his work to make sure a good job was done.

I was very pleased with the door repair, and the last-minute light switch repair was above and beyond! I look forward to booking additional projects and wouldn't hesitate to recommend this service!

They were quick to respond and provided a flat fee to repair a door that had expanded and could no longer close. The fee was reasonable and communication was good. Job was done quickly and a video of the repair texted to me before payment was made. I would use them again

Responded quickly and was able to do the work same day. The quality was excellent and I would not be hesitant to call for other projects in that area.

Alex did a great job fixing our french doors. He arrived on time and worked steadily until the job was finished. Communication was excellent , we would use them again and we would definitely recommend Knock Knock contractors.

We had an excellent experience with Knock Knock Contractor. Nurlan replaced our side garage door and frame, and the results were perfect. He took care of everything from picking up the new door and paint to completing the full installation. The door and frame were leveled and aligned with great attention to detail, and the work was completed on time and on budget. Professional, reliable, and easy to work with: highly recommend for anyone needing quality home repair or installation.
