Home Improvement Services

Refresh the Exterior of Your Home

Siding

Deteriorating siding can not only affect curb appeal but also increase the risk of moisture infiltration. Allow us to equip your home with the lasting protection and beauty of fiber cement siding, engineered wood siding, vinyl siding, or cedar shake siding.

Improve Functionality and Energy Efficiency

Windows

Don’t let drafty windows drive up your energy costs. Instead, invest in replacement windows that minimize heat transfer and can help lower monthly energy bills. Select from vinyl, fiberglass, or wood windows, and include self-cleaning glass for easy maintenance.

Upgrade Your Home’s Entryways

Doors

You’ll be amazed at how much of an improvement a new wood, fiberglass, or steel front door can make to your home’s curb appeal and security. We also install elegant patio doors that feature the same energy-efficient glass as our windows.

Equip Your Home With Lasting Protection

Roofing

As your home’s primary shield against the forces of Mother Nature, roofing can take a beating over the years. If your roof is due for replacement, we can upgrade it with high-performance asphalt shingle roofing or metal roofing.

Live Your Outdoor Lifestyle to the Fullest

Decks

Do you love spending time in your yard? If so, maximize your enjoyment of your outdoor living space with a beautiful wood or composite deck designed and built by our expert team.

John and his team at Green City were beyond helpful with our window replacement. They gave us a time frame after ordering the window and surprised us with a call before we expected. They were out the following morning to install the window with no issues; couldn't even tell they were there. I would definitely recommend them.

- Zach D.

I recently contracted with Green City to provide and install 17 windows, 2 Sliding Glass Doors, Full House Siding replacement, new gutters and downspouts, and 3 decks. It is a huge project. John and his team did an excellent job, were very professional and friendly. John was always responsive and provided great detail and information on all my questions. I always felt that John and his team kept my best interests in mind. I would definitely use their services again.

- Karen J.

We've used John's crew before for window replacement so there was never a doubt who to call when we needed more done. As before, Green City came through admirably. We'd recommend them to anyone and will certainly call John again should we need more work done!
