Great Day Improvements, a national leader in home improvement, today announced the appointment of Grant Davis as Chief Executive Officer.

Davis is a proven leader with more than 25 years in the home improvement and building materials industry. Since joining Great Day in 2025 as Chief Retail Officer, he has worked closely with the leadership teams at Champion Windows & Home Exteriors, Universal Windows Direct, Leafguard, Englert, and Patio Enclosures.

Davis succeeds Drew Weinfurtner who will be leaving the company to pursue other entrepreneurial interests. Ed Weinfurtner has recently announced that he will retire as Executive Chairman of the board. The Weinfurtners, who led the growth of Great Day for over a decade, remain investors and will continue to serve as board members in support of Davis.

“The past year I’ve spent working alongside Ed, Drew, and our teams across the country has been invaluable,” said Davis. “We will put our customers first, support our people, and take pride in delivering on our commitments. I’m honored to help lead this team into our next phase of growth while continuing to provide homeowners with an unmatched home improvement experience at every turn.”

Before Great Day, Davis served as Senior Vice President and General Manager of the Residential and Commercial Pro divisions at Andersen Corporation. Earlier, he spent 12 years at Renewal by Andersen, where he led the Chicago market and later ran the company’s retail operations across several states.

“I’m looking forward to supporting Grant through this transition and have the utmost confidence in his ability to lead our teams and deliver excellence to homeowners across the country,” said Drew Weinfurtner.

Davis’s appointment ensures continuity in Great Day’s strategic direction while positioning the company to build on its established strengths and pursue new opportunities for growth.

“We thank Ed and Drew for their leadership and the lasting impact they have made on Great Day,” said Steve Raich, Managing Partner at Littlejohn & Co., Great Day’s majority owner. “Grant is uniquely positioned to lead Great Day into its next chapter, bringing industry expertise, proven operational leadership, and firsthand knowledge of Great Day’s brands, people, and businesses. Littlejohn remains firmly committed to the company’s long-term strategy.”

Great Day Improvements is majority owned by Littlejohn & Co., a private investment firm based in Greenwich, Connecticut, which has invested in middle-market companies since 1996.
