Buying Guide: Key Considerations For Choosing Cellar Doors
What opening size do you have?
Measure width, length, and height precisely. Choose a door that fits the opening with a comfortable margin for installation and weatherproofing. If your areaway is angled, look for doors designed to fit angled openings.
What finish or coating is required?
Some doors come primed or finished and require painting after installation. Consider maintenance plans, outdoor exposure, and color-matching needs when selecting a finish approach.
How important is security?
Look for interior hinges, lock options, and robust materials (steel or reinforced composites). Exterior bulkheads with interior locking systems provide added protection against unauthorized access.
Is weatherproofing a priority?
Weathertight designs with flanged construction shed water and reduce ice binding. For basements in snowy or wet climates, prioritize flanged or sealed designs and a door profile that resists water intrusion.
Are angled openings common in your home?
For angled or irregular areaways, select a bulkhead door specifically designed for angled openings to ensure a proper fit and secure seal.
What about installation effort?
Some doors require professional installation, especially heavy steel bulkheads. Others with standard sizes and primer finishes may be easier for DIY installation, but plan for painting after mounting.
