How It Works

  1. Our Technology and Process
Design Partners, One Day Doors & Closets

Choose Your Door Style & Get Your Doors Digitally Measured

Once you’ve selected the style of door that achieves the look you’re targeting for your client, a One Day technician will capture digital measurements of each door opening using patented 3D measuring technology.

This precision mapping technology enables each door to be custom-made to fit each unique opening. This is key as it guarantees a great fit every time with no excessive gaps or rubbing on the frame.

Custom-Made Doors & Professionally Painted

Your measurements are then sent to One Day’s factory where each door is custom-made using robotic automation similar to 3D printing.

This is where your doors are professionally painted with advanced coatings paint and flash-dried by a laser-controlled infrared oven, creating quality and durability unmatched in the market.

Get It Installed

Now comes the easy installation process.

One Day install crews arrive, scheduled with your client, and quickly get to work. Every door in your client’s home is replaced in less time than it takes home improvement stores, handymen and contractors to replace a single door!

Instead of a 1 to 2 week messy construction project, installation is finished in only a few hours with no in-home mess or construction, and typically costs 30 to 50-percent less than hiring a contractor or handyman.
