About Duane Kinna Home Improvements

I started doing home improvements in 1989 on a part-time basis with a friend that I graduated from high school with while maintaining a full-time job. As business grew, so did my reputation, and I received many referrals from local businesses. I left my full-time job to start Duane Kinna Home Improvements. Some of my projects and clients include: The Parent/Child Center, First Data, Premium Outlets, The Valley Mall, Westside Floral and The Good Shepherd Ministries. For the past 2 years I have been a certified installer for Climate Seal which is an interior window insert that has thermal and acoustical performance. With this insert installed over your existing windows you can gain up to 40% year round efficiency. They can be used in historic homes, churches, schools, office buildings, retail businesses and residential homes. My projects have included:  historic buildings, townhouses, Mexican and Swaziland Embassies in Washington, DC, Harpers Ferry National Park Service, Georgetown University/DOD lab, and many residential homes.

  • Basement Remodeling
  • Major Renovations
