Pritchett's Closets & Blinds is a closets and blinds company that Jay Pritchett formerly owned and worked at.
Jay owned the company for many years and, being the owner of the company, became very rich in his later life.
In his younger years, while he was still married to Dede and their children Claire and Mitchell were still children, they were living paycheck to paycheck and Jay was working all the time and was almost never around, working his tail off to provide food and shelter. It appears that Jay working all the time caused Dede to become crazy later as said in "Arrested".
In "First Days", Claire takes her father's proposal and starts working at her father's company Pritchett's Closets & Blinds, after 20 years of being a housewife and stay-at-home mom. She, is, later on, made into the CEO of the company cause Jay always knew that she was like the Son" he always wanted to nurture and that she was the right and fitting heir to his baby Pritchett's Closets & Blinds.
Ever since Jay's retirement in "White Christmas", Claire runs the company and it is agreed that after her, it would be either Haley, Alex (Claire's Daughters) or Lily (Mitchell's Daughter). At the end of season 9, Episode 22 Claire and Jay agree to meet the new kids on the block in closeting Ezravision, which is run by a group of college graduates, thinking that they needed to meet her and her dad for some good old advice about the closet industry. But to their shock, Claire gets an offer from the nerds to sell the company to Ezravision. Jay asks those 'nerdy kids' to get out twice and they inform Jay that the offer stands up for 48hrs. They then find out that their long time worker Margaret is hired by that new company when Claire is strolling through their website and they now call her Margie. Jay and Claire decide to get Margaret back and both of them pay a visit to the new company. Claire is now on thin ice after seeing their new high tech voice automated robotic closet which looks like the one in James Bond movies. Claire tells her dad that they have to take the offer. Jay becomes furious but Claire tells her dad that they won't be selling their dream company but rather will be saving it's hereditary and the legacy of Pritchett's Closets & Blinds by merging with Ezravision. She came up with this brilliant plan after she had done some digging, by which she found out that Ezravision was 2 years behind on production. So she wants to talk them into a merger with her and her dad's company. She tells Jay that they need their manufacturing and in exchange Pritchett's Closets & Blinds needs Ezravision's new technology. At first, Jay is furious but later he comes around the idea when Claire returns back after storming out of the Ezravision headquarters. Jay tells his daughter Claire that he is afraid that he might not be able to keep up with the kids cause he is bad with technology. Claire tells her dad that he's irreplaceable and that the new generation needs people like him, she tells him that his stories and legacies are now bound to go to the next generation and who else is capable of telling those revolutionising stories than Jay himself. Thus, both daughter and father agree to the merging of the great Pritchett's Closets & Blinds with the high tech closet company Ezravision. In the end, we can see but only she and her dad going there, which means that the Pritchett's Closets staff got laid off except Margret who is already working at Ezravision. Thus a golden era comes to a beautiful end or may we say a wonderful new beginning.
