About K&A1 Home Improvement

Nearly 50 years of trusted service to Maryland homeowners

Who We Are

We started K&A1 back in 1975 right here in Abingdon. Just a family business doing home improvement the right way—showing up when we say we will, doing good work, and charging what we said we would. 


Almost 50 years later, we're still at it. Same approach, same values. We work all over Harford, Cecil, and Baltimore Counties. Could be a new deck, a kitchen remodel, or just replacing some old windows. Whatever makes your house better. 


Most of our work comes from word of mouth, which tells you something. People call us because their neighbor or cousin had a good experience. That's how we like it.
