For decades, BILCO has been one of the most recognizable names in the cellar door industry. In some parts of the country, particularly in the Northeast, the brand name became so familiar that homeowners began using “BILCO door” almost as a generic description for an exterior basement entrance.
Today, the organization behind that well-known name looks different.
In 2024, Quanex Building Products completed its acquisition of Tyman plc, BILCO’s parent company. As a result, BILCO became part of a much larger international building-products organization serving a broad range of residential and commercial markets.
The acquisition is an example of the consolidation that has become increasingly common throughout the building-products and manufacturing industries. Established brands are frequently brought into larger organizations with broader portfolios, greater distribution, and operations extending across multiple product categories.
For homeowners, contractors and building professionals comparing cellar doors, the change creates an interesting distinction within the marketplace. BILCO is now one brand within an expansive global building-products portfolio. Steelway, meanwhile, has remained focused on the product category it has served for more than six decades: cellar doors and access solutions.
That difference does not mean that one organizational structure is automatically better than another. It does, however, provide a useful reason to look beyond brand recognition and consider how a manufacturer’s experience, product construction, custom capabilities, and support align with the requirements of a particular project.
BILCO became part of Quanex through the acquisition of Tyman rather than through an independent purchase of the BILCO brand. The company continues to be an established name within the cellar door and access-product market, but it now exists within a much broader portfolio of building products and components.
There can be significant advantages to being part of a large organization. Global manufacturers may benefit from broader operational resources, distribution networks, purchasing power, and investment capabilities.
At the same time, a diversified organization represents a different model from that of a specialized manufacturer whose history remains concentrated within a narrower product category.
Steelway follows the latter model.
Since 1963, Steelway has remained closely connected to cellar doors and related access products. Over that time, the company has manufactured standard doors for common applications while also developing custom solutions for properties where a stock-size product cannot provide the appropriate fit.
For customers comparing their options, the most useful conversation is therefore not simply about company size or name recognition. It is about specialization, construction, fit, flexibility, and the ability to address unusual applications.
Steelway’s approach to cellar doors has been shaped by more than six decades of manufacturing experience and by the wide range of real-world conditions encountered in replacement and new-construction projects.
At first glance, an exterior basement door may appear to be a relatively simple building product. In practice, however, the success of the installation depends on a close relationship between the door, its frame, the supporting foundation, and the dimensions of the opening beneath it.
A well-manufactured cellar door can still be the wrong product if it does not fit the opening correctly.
That reality has influenced Steelway’s product philosophy from the beginning. The company manufactures standard doors for common residential applications, but it has also maintained the ability to produce custom doors for unusual dimensions and configurations.
This flexibility is particularly important in the replacement market, where contractors and homeowners are working with existing structures rather than designing a new foundation around a predetermined product.
Older homes may have basement entrances that were constructed decades ago. Foundations may have settled. Concrete and masonry may have deteriorated or been repaired. Previous owners may have altered the opening or installed replacement products that changed the original dimensions.
As a result, the opening that exists today may have very little in common with a current standard size.
Steelway’s experience in these situations has reinforced a straightforward principle: the product should be selected to fit the application rather than forcing every application to conform to the product.
Custom manufacturing is valuable, but that does not mean every cellar door needs to be custom-built.
For many homes and buildings, a standard-size product is exactly the right solution. When the opening corresponds to a common configuration and the supporting foundation is in good condition, a standard door can provide a practical and efficient replacement.
Steelway manufactures standard cellar doors with these common applications in mind.
The challenge arises when an opening does not correspond to a stock dimension. In new construction, it may be possible to design the foundation around the product. Replacement projects are different. The installer has to work with the structure that already exists.
That may mean an opening that is several decades old, slightly out of square, or affected by years of repairs. The dimensions may fall between standard product sizes, or the configuration may be unlike those found in modern construction.
In those situations, a manufacturer’s ability to offer alternatives becomes especially important.
The decision should not begin with the assumption that the home must be altered to fit a standard product. It should begin by evaluating the opening and determining whether a stock or custom solution is more appropriate.
Custom fabrication is sometimes associated with specialty architectural projects or unusual commercial applications. In the cellar door market, however, the need for custom manufacturing is often much more practical.
Homes throughout the country were built using different regional construction practices and during different periods of residential development. Basement entrances were not created according to one universal standard.
Over time, those variations become even greater. Foundations settle, repairs are made, concrete is patched, renovations alter the structure, and replacement doors are installed.
The result is a substantial number of properties where an off-the-shelf product may not provide an appropriate fit.
Steelway’s custom manufacturing capabilities allow the company to produce doors for a range of unusual dimensions and applications. The value lies not simply in being able to call a product “custom,” but in having another practical option when standard dimensions do not work.
For contractors, that flexibility can reduce the need to make unnecessary changes to an existing foundation solely to accommodate a catalog product. For homeowners, it can mean having a replacement designed around the property rather than substantially modifying the property around the replacement.
There are situations where foundation work is necessary, and a custom door cannot solve every structural problem. However, having the option to manufacture around a non-standard opening gives both homeowners and contractors greater flexibility in determining the appropriate solution.
Brand familiarity plays a significant role in the way consumers make replacement decisions. If a BILCO door has been installed on a home for decades, the most obvious next step may appear to be purchasing another BILCO door.
That may be the correct choice for some projects, but the existing brand should not automatically dictate the replacement.
The more important information comes from the current condition of the opening.
The dimensions should be measured accurately. The supporting foundation should be evaluated. The configuration of the entrance should be considered, and the condition of the existing installation should be understood.
Once that information is available, the homeowner or contractor can determine whether a standard replacement is appropriate or whether another approach would provide a better fit.
An older BILCO door can be replaced with a Steelway product when the Steelway configuration is appropriate for the application. The same principle applies to doors manufactured by other companies.
Replacement should be treated as an opportunity to evaluate the property as it exists today rather than simply duplicating a product selection made many years ago.
Brand reputation is an important consideration when purchasing any building product, but it should be only one part of the evaluation.
Construction is an appropriate place to begin. Customers should understand how the door is manufactured, what materials are used, and how the assembly is designed to stand up to repeated operation and long-term exposure to rain, snow, temperature changes, and outdoor conditions.
Steelway’s approach includes fully welded construction, durable metal components and attention to the fit and function of the complete assembly.
The next consideration is fit. A high-quality door can still become the wrong solution if it is installed over an opening for which it was not designed. Accurate measurements and an understanding of the foundation should therefore guide product selection before a particular model is chosen.
Custom capability is another important distinction. Customers should understand what options are available when the opening does not correspond to a standard size. A manufacturer that can address unusual dimensions may provide alternatives to extensive structural modification.
Support and product knowledge also matter. Cellar doors are not products most homeowners purchase regularly. A customer may replace only one during the entire period they own a home. They should be able to ask questions, understand their options, and receive guidance when an application falls outside of a straightforward standard replacement.
Contractors benefit from the same level of support. An unusual opening can quickly turn a routine project into a more complicated one, and access to a manufacturer familiar with those conditions can be valuable.
Price is certainly part of the decision, but it should be considered alongside construction, fit, customization, and long-term suitability. The least expensive product is not necessarily the least expensive project if substantial changes are required to make it work.
Large, diversified building-product manufacturers and specialized manufacturers develop expertise in different ways.
A global company may accumulate knowledge and resources across a wide range of products and markets. A specialized manufacturer develops experience through repeated exposure to a narrower group of applications and problems.
Steelway’s experience has largely been shaped by the second approach.
More than six decades in the cellar door category means repeated exposure to standard installations, older foundations, unusual dimensions, contractor questions, retrofit challenges, and custom applications.
These situations create a form of product knowledge that extends beyond manufacturing alone. They help a company understand how its products are actually used once they leave the factory.
That distinction is particularly important in replacement work, where the conditions in the field rarely match a perfect drawing.
An opening may be out of square. A foundation may have been patched. A previous door may have been improperly sized. Measurements may be unusual. These are not exceptional situations in an industry that routinely works with homes built decades ago.
A manufacturer that remains closely connected to the category sees those problems repeatedly and can use that experience to inform both product development and customer support.
The traditional sloped cellar door has been part of American residential construction for generations. Because the product is so familiar, it is easy to assume that there is little opportunity for change.
In reality, long-established building products can continue to evolve.
Manufacturing methods improve. Fabrication capabilities change. Materials and hardware advance. Feedback from contractors and installers can identify areas where a traditional design can be refined.
Steelway has used its manufacturing and field experience to develop its own approach to the cellar door category rather than treating the product as something that should remain unchanged simply because the basic concept has existed for decades.
This is another benefit of specialization. When a product category remains central to a company’s business, small details continue to receive attention.
Issues reported in the field can influence future manufacturing decisions. Recurring installation challenges can lead to new solutions. Custom projects can reveal needs that may eventually inform other products.
A cellar door may be a relatively straightforward component of a building, but its design still deserves careful consideration.
BILCO’s history has helped define the cellar door market, and the brand deserves recognition for achieving a level of familiarity that few building-product companies ever reach.
At the same time, homeowners and contractors have alternatives.
Steelway has manufactured cellar doors since 1963, and its position in the market is based on a different model: specialization, standard and custom manufacturing, and a long-standing focus on the needs of basement entrances.
Quanex’s acquisition of Tyman does not erase BILCO’s history, nor does it automatically determine which manufacturer is right for a particular project. What it does is make the contrast between different types of building-product companies easier to see.
One well-known cellar door brand now operates within a much broader international organization. Steelway remains concentrated on the category it has served for more than 60 years.
That gives homeowners and contractors meaningful choices.
The best way to evaluate those choices is not by beginning with the logo on the existing door. It is by beginning with the opening itself.
Accurate measurements, foundation condition, product construction, available sizes, custom capabilities, and support should all be considered before a replacement is selected.
That process may lead to a standard Steelway product. It may lead to a custom Steelway door. In other situations, a different product may be appropriate.
What matters is that the selection is based on the requirements of the project.
Building-product companies will continue to merge, expand, and change ownership. The industry will evolve, and established brands will continue to find new places within larger organizations.
Steelway’s core focus has remained comparatively consistent.
Since 1963, the company has continued to manufacture cellar doors, serve standard residential applications, and develop custom solutions for projects where conventional dimensions do not work.
That consistency does not mean the products have remained unchanged. It means the cellar door category has remained important enough to the company to continue receiving focused attention.
For homeowners researching a replacement for an existing BILCO door, Steelway provides an alternative built around that specialization. For contractors, it provides access to both standard and custom products from a manufacturer familiar with the challenges found in real-world basement openings.
If you are comparing BILCO and Steelway, replacing an older cellar door or working with an opening that does not match common dimensions, begin with the application rather than the brand name.
Steelway offers both standard and custom cellar door solutions for projects throughout the country. Explore the available options or contact the Steelway team to discuss the dimensions and requirements of your project.
