HISTORIC PRESERVATION · WINDOWS

Introduction

The Greater Cincinnati region — stretching from the Ohio side of the river down through the Northern Kentucky communities of Covington, Newport, Bellevue, Dayton, Fort Thomas, and beyond — has one of the most remarkable concentrations of intact 19th-century architecture in the country. On both sides of the Ohio River, neighborhoods full of Victorian rowhouses, Greek Revival homes, and Italianate storefronts have been carefully preserved. And that preservation comes with real implications for homeowners who want to replace windows.

Whether your property is in a Cincinnati neighborhood like Over-the-Rhine or Hyde Park, or in a Northern Kentucky community like Covington’s MainStrasse Village or Newport’s historic district, the rules are similar: you cannot simply order whatever replacement window catches your eye. Designated historic districts on both sides of the river require formal review and approval before exterior alterations are made — and that includes windows.

The good news is that some of today’s wood windows with aluminum cladding are specifically engineered to meet those requirements while delivering everything a modern window should. At Tri-State Wholesale Building Supplies, guiding homeowners and contractors through historic district window projects is one of the most important conversations we have. Here’s what you need to understand before starting a window replacement project in a historic district — and what your options are.

Which Neighborhoods Are Affected?

The Greater Cincinnati and Northern Kentucky area contains dozens of designated local historic districts. If your property falls within one, any exterior alteration visible from a public right-of-way will likely require formal approval before work can begin. The affected areas span both sides of the river.

If you’re not sure whether your property is in a designated district, contact your local preservation office before purchasing windows, signing a contractor agreement, or beginning any exterior work. For Northern Kentucky properties, the Kentucky Heritage Council (KHC) serves as the State Historic Preservation Office and is a good starting resource.

The Approval Process: What to Expect

On the Ohio side, Cincinnati’s Historic Conservation Office issues a Certificate of Appropriateness (COA) before exterior alterations can proceed. In Northern Kentucky, the process varies by municipality but follows the same principle: a local historic preservation commission reviews proposed changes and issues a formal approval — often also called a Certificate of Appropriateness — before work begins.

In Covington, for example, the seven Historic Preservation Overlay zones each carry design review requirements enforced through the Historic Covington Design Guidelines. Newport’s Historic Preservation Commission oversees its districts with similar authority. Bellevue operates as a Certified Local Government (CLG) in partnership with the Kentucky Heritage Council and National Park Service, giving its preservation program formal standing at the state and federal level.

Regardless of which municipality you’re in, the review process for windows typically evaluates the same things:

• The material of the replacement window — wood or aluminum-clad wood is generally required for primary facades; standard vinyl is typically not approved
• Whether the profile and sight lines of the new window match the originals
• The divided lite pattern — grille configurations must accurately reflect the home’s period and style
• Exterior color of the cladding or finish
• Whether the size of the opening is being changed

Why Vinyl Windows Are Typically Not Approved

Standard vinyl windows — including high-quality double hung and casement units — are generally not approved for use on the primary facades of homes in designated historic districts, whether in Cincinnati or Northern Kentucky. The reasons are consistent across preservation commissions:

• Vinyl has a distinctly different visual profile and surface texture than the original wood windows these homes were built with
• The sash thickness, sight lines, and proportions of vinyl windows typically do not replicate the appearance of historic wood windows closely enough to satisfy preservation guidelines
• Grids between the glass — standard on most vinyl windows — are generally not accepted; simulated divided lite construction with a spacer bar between panes is typically required

This is not a criticism of vinyl windows. They’re an excellent product for the right applications, and we manufacture them right here in Cincinnati. But in a historically designated district on either side of the river, the material and profile requirements are specific, and vinyl doesn’t meet them for front facades.

Our Historically Appropriate Window Lines

Lincoln Windows

Lincoln is one of the most respected names in the architect-grade window market, and their aluminum-clad wood line is purpose-built for projects where profile accuracy and finish quality are non-negotiable. Lincoln uses heavy-gauge extruded aluminum cladding — .050″ thick — finished to the AAMA 2605 standard, the highest exterior paint performance rating in the industry. That means the finish resists fading, chalking, and peeling for decades, even under the full range of Ohio and Kentucky weather.

Lincoln offers an exceptional range of interior wood species, factory-stained or primed to specification. Lincoln also offers virtually unlimited custom exterior colors — important when a preservation commission asks you to match an original finish precisely.

Quaker Windows

Quaker Windows & Doors has built a strong reputation for aluminum-clad wood windows that deliver authentic historic profiles at a strong value. Quaker’s clad wood line is a popular choice for historic district projects across the Midwest, offering double-hung, casement, and specialty configurations with the sight lines and proportions that preservation reviewers look for.

Quaker is particularly well-regarded for their ability to accommodate non-standard sizing — which is critical throughout the tristate region’s older housing stock, where window openings rarely conform to today’s standard dimensions. Whether you’re working on a pre-Civil War home in Covington’s Riverside Drive district or a late-Victorian rowhouse in Cincinnati’s West End, Quaker’s flexibility in sizing and grille configurations makes it a consistently dependable choice.

Sierra Pacific Windows

Sierra Pacific is a family-owned, vertically integrated manufacturer — they grow their own timber, mill their own lumber, and build their own windows. That control over the full supply chain produces exceptional consistency in the wood and in the finished product. Their aluminum-clad wood line offers a clean, precise profile with excellent glass-to-frame ratios that suit both traditional and transitional historic architecture.

Sierra Pacific’s extensive custom color options and their ability to produce true divided lite configurations — not just simulated — make them a strong candidate for the most demanding historic preservation projects, including properties listed on the National Register of Historic Places on either side of the Ohio River.

What About Aluminum Windows?

Aluminum windows have a specific and legitimate role in historic preservation work. Many properties throughout Greater Cincinnati and Northern Kentucky — particularly mid-century commercial buildings, industrial conversions, and some residential structures — were originally built with aluminum windows. In those cases, replacing deteriorated aluminum windows with new aluminum windows is often entirely appropriate, and may even be preferred by preservation reviewers over introducing wood where it wasn’t original.

Tri-State Wholesale carries the Crystal aluminum window line, which is suitable for historic applications where aluminum is the appropriate material. If your property was originally glazed with aluminum windows — or if your local preservation commission has indicated aluminum is acceptable for your specific project — Crystal is worth discussing with our team.

The Bottom Line

Owning a home in one of Greater Cincinnati or Northern Kentucky’s historic districts is something worth protecting. The architecture on both sides of the Ohio River tells a story that goes back nearly 250 years, and the preservation requirements that govern these neighborhoods exist to ensure that story stays intact. Window replacement in a historic district isn’t as simple as a trip to the home center, but with the right guidance and the right product, it’s a straightforward process that results in windows you’ll be proud of for decades.

Tri-State Wholesale Building Supplies has been supplying homeowners and contractors throughout Greater Cincinnati and Northern Kentucky for over 50 years. We carry Lincoln, Quaker, and Sierra Pacific aluminum-clad wood windows specifically because they meet the standards that historic districts require — on both sides of the river — and because they’re exceptional windows regardless of where they’re installed.
