Upgrading your cellar door might not be the most glamorous home improvement project, but it can make a big difference in safety, comfort, and even energy efficiency. Whether you’re remodeling your basement or replacing an old door, knowing what to expect with cellar door installation costs can help you make smart decisions without breaking the bank.
What Is a Cellar Door (a.k.a. Bulkhead Door)?
A cellar door, also called a bulkhead door, is an outdoor entryway that leads directly into your basement. These exterior doors are usually built at an angle and rest on a small staircase going down to your basement level.
Many older homes come with metal or wooden doors, and over time, they may rust, warp, or leak. Newer design options include doors with durable material like steel, fiberglass, or even glass inserts for extra light. Some people even choose French doors or double doors for larger spaces.
Whether you’re replacing old slab doors or adding custom cellar access during a basement finishing project, a quality door keeps out water, adds security, and boosts your home’s value.
Average Cost of Cellar Door Installation
Now, let’s talk about the numbers. The average cost of cellar door installation varies a lot depending on your location, the materials, the size of the opening, and how complex the job is.
For most real-world projects, you can expect to pay anywhere between $1,200 and $3,000. Here’s a simple way to break it down:
- Material costs: $400–$1,200
- Installation labor: $600–$2,000
- Additional costs (like waterproofing, stairs, or foundation fixes): Varies widely
These are just cost ranges, but they give you a good idea of what’s typical. The project cost goes up with premium materials, customization options, and any required repairs to the frame, walls, or basement entry.
Keep in mind that labor rates change by region, and bigger or Larger doors often take more labor hours, especially if the project scope involves cutting into walls, reworking the aluminum frame, or dealing with structural integrity issues.
What Impacts the Cost of a Cellar Door Project?
The total project cost of installing or replacing a cellar door comes down to a mix of materials, labor, and complexity. Here are the top factors:
1. Material Prices and Quality
- Steel: A durable option, popular for security.
- Fiberglass: Great for resisting moisture and rust.
- Wooden doors: Classic but need more maintenance.
- Glass or Low-E glass for extra style and energy-efficient glass performance.
Different material costs impact the price range. You might find galvanized options that cost less upfront or expensive options with fancy design features or extra features like insulation and security locks.
2. Labor Costs
Expect to pay for Installation labor, which often includes cutting, fitting, sealing, and finishing the opening. The average labor cost ranges from $75 to $150 per hour, depending on the region and project complexity.
3. Size and Style
- Smaller doors like bifold doors or standard hatches are easier to install.
- Larger doors, double doors, or custom shapes take more work and add to the frame replacement costs.
4. Frame Condition
If the existing frame or walls are damaged, cracked, or rotted, that will raise your project scope. You might need new supports, drainage, or a completely rebuilt entrance.
DIY or Hire a Cellar Door Installer?
Some homeowners think they can save on labor costs by going the DIY route. While it’s tempting, this kind of improvement project often calls for a professional cellar door installer.
DIY:
- Pros: You might save money on labor hours.
- Cons: It’s risky. If done wrong, it can cause water leaks, drafts, and structural damage.
Professional Installer:
- They’ll ensure the frame is level and sealed.
- They’ll check for insulation, moisture issues, and code requirements.
- They can handle complexity like cutting through masonry or dealing with a sloped yard.
Professionals also offer affordable financing options, which is helpful if the project cost climbs due to additional features like a Drop Ceiling, Drywall ceilings, or matching Screen doors.

Additional Costs You Might Not Expect
When you think of cellar door installation, it’s easy to focus just on the door itself. But sometimes there are additional costs that sneak into the project scope, especially in older homes or basement projects with moisture or structural problems.
Hidden or Extra Costs to Watch For:
- Waterproofing: If your basement has leaks or standing water, you may need a drainage system installed near the door.
- Stairs and Entryway: Damaged steps or an unsafe entrance can increase the labor costs or require concrete work.
- Framing Work: A new frame might be needed if the old one is rotted or cracked. Frame replacement costs vary by material.
- Permits: Some areas require permits for exterior doors or structural work. That can cost $100–$500 depending on local rules.
- Interior Finishing: If your project is part of a basement finishing project, the area around the new door may need fresh paint, trim, or even a new Drop Ceiling or Drywall ceilings to finish it off.
All these extras can push the project cost higher than expected, especially if you’re dealing with complexity or multiple trades like masonry, carpentry, and waterproofing.
When to Replace vs. Repair a Cellar Door
Not every improvement project needs a total replacement. Sometimes simple repairs can fix the issue. But other times, replacement is the smarter and safer call—especially if the door is affecting your home’s structural integrity.
When Repairs Might Work:
- Loose hinges or minor dents
- Small gaps that can be sealed
- Worn weatherstripping
When Replacement Is Best:
- Visible rust, rotting, or holes in the door
- Leaks or signs of water damage in your basement
- The door no longer fits the frame properly
- Drafts or poor insulation causing heat loss
- You’re upgrading your basement as part of a larger remodel
If you’re working with older slab doors or want to upgrade to energy-efficient glass, a full replacement gives you more customization options and longer-lasting results.
Common Mistakes to Avoid
No one wants to redo a job they’ve already paid for. To make your basement projects smooth and stress-free, avoid these common mistakes:
- Choosing the Wrong Size: Be sure to measure carefully. Pre-hung doors, bifold doors, and Larger doors all need exact fitting.
- Skipping Waterproofing: Even the best door won’t help if water’s leaking in from cracks around the entrance.
- Hiring Inexperienced Installers: A professional cellar door installer should understand how to manage slopes, drainage, and frame alignment.
- Overlooking Permits: Not pulling a required permit could cost you fines—or force you to redo the job.
- Not Budgeting for Add-Ons: Things like decorative glass options, insulation, or updated features can raise the final bill.
Think of this like any other improvement project: Planning and research go a long way toward preventing regrets (and extra labor hours).
Custom Features and Style Options
Today’s cellar doors go way beyond plain metal panels. There are plenty of design features and affordable options to match your home’s look, function, and budget.
Popular Choices:
- Steel with Powder Coating: A durable option with weather resistance
- Fiberglass: Lightweight, long-lasting, and great for humid climates
- Wooden Doors: Stylish and traditional, but higher maintenance
- French Doors or Double Doors: Great for basement ceiling areas with walkout access
- Decorative & Glass Inserts: Add natural light and modern charm
- Energy-Efficient Glass: Like Low-E glass, it cuts down on energy bills
If your project scope includes turning your basement into a living space, you may also want to pair the door with screen doors, upgraded locks, or security lighting. The right choices will not only improve your home’s curb appeal but also protect your basement finishing project from moisture and cold.
Many companies now offer affordable financing options for full installations, especially if your plan includes custom or premium materials.
Smart Planning Leads to Smart Spending
Whether you’re replacing a leaky old hatch or designing a custom entry as part of a full basement remodel, your cellar door installation can be as simple or as advanced as you need it to be.
By understanding the average cost, planning for additional costs, and choosing the right materials and features, you’ll avoid surprises and stick to your budget. Look for local pros with experience in basement projects, compare estimates, and explore affordable options that still give you the quality and durability your home deserves.
From pre-hung doors to glass inserts, and from durable material to attractive design features, your choices can turn this overlooked entrance into one of the most practical and well-designed parts of your home.

Frequently Asked Questions
What’s the difference between a Bilco door and a cellar door?
A Bilco door is a branded type of bulkhead door, while a cellar door is a more general term. Bilco doors are known for quality, code compliance, and weather resistance, and they are a top choice for basement entry doors. These doors are pre-engineered and built with strong materials like steel doors, making them ideal for keeping basements dry and secure. A general cellar door could include wooden bulkhead doors, composite wood doors, or fiberglass doors, depending on the home’s design. While all Bilco doors are cellar doors, not all cellar doors meet the standards of a Bilco product. This brand is often selected for its reliability in exterior door installation and because it works well for both flat cellar doors and angled units.
Can I replace my cellar door myself?
Replacing a cellar door yourself is possible, but it’s not easy. It depends on your experience with exterior door installation and your ability to handle complex installations. A bulkhead door replacement often requires framing, sealing, and sometimes working around a load-bearing wall. It may also involve excavation or concrete cutting. You’ll need to measure the standard size accurately, remove the old unit, and install the new one securely to prevent leaks and heat loss. Mistakes can affect the security systems, energy use, and air circulation of your basement. Hiring a professional door installer ensures the job meets building codes and avoids additional labor later. DIY might save you on the upfront cost, but hiring a pro helps with getting an accurate quote, safety, and long-term performance.
Do I need a permit to install a new bulkhead?
Yes, in most cases, installing or replacing a bulkhead door requires a permit. Since this type of work affects the structure and safety of your home, it often involves strict building codes. Permits are typically needed when working with an exterior wall, modifying a load-bearing wall, or digging near the foundation. Depending on your location, permits may also be required for electrical or drainage upgrades associated with the bulkhead door installation. Failing to get a permit could lead to fines or having to redo the work. Always check with your local permitting office before beginning. A full-service door installation company can usually handle the paperwork, ensuring your basement remodel costs stay on track and up to code.
Are cellar doors energy efficient?
Modern cellar doors can be very energy efficient if built with excellent insulation and properly installed. Materials like fiberglass doors, steel doors, and even solid-core door designs help block drafts and maintain consistent temperatures in your entire basement. Adding extra insulation or choosing doors with glass panels using fire-rated steel or composite wood doors can increase efficiency. Poorly installed doors or those showing signs of wear allow air leaks and moisture in, raising heating and cooling bills. An energy-efficient door isn’t just about materials—it also depends on proper sealing, fitting, and eliminating gaps. Always ask for expert advice or an accurate quote from basement door installers to make sure your new door improves energy performance and adds value.
What’s the lifespan of a typical steel bulkhead door?
A steel bulkhead door typically lasts 30–50 years, depending on maintenance, weather exposure, and usage. These types of doors are durable and rust-resistant, especially when treated or powder-coated. However, foot traffic, salt, and moisture can shorten the lifespan if not managed. To extend its life, inspect it regularly for signs of wear, repaint when needed, and keep the hinges and seals clean. Doors located in high-moisture areas or near coastal zones may benefit from galvanized or fire-rated steel options to resist corrosion. Compared to wood doors or Entry-level wood doors, steel doors offer superior lifespan and require less upkeep. If your basement size or use has changed, updating the door may also improve function and potential buyers’ appeal.
How do I prevent water from leaking into my basement through the cellar door?
To stop leaks, you’ll need both proper installation and sealing. Water commonly enters through gaps in the frame, poor grading, or old seals. Start by ensuring the door has weatherproof gaskets and that the surrounding concrete or exterior wall slopes away from your home. Install a drain or sump pump if needed. Applying waterproof coatings and checking the caulking can help too. If your door has glass doors or doors with glass panels, make sure they’re sealed and rated for exterior use. Many common repairs involve fixing flashing or replacing worn weatherstripping. Calling a professional door installer for an accurate quote ensures the leaks are stopped at the source—especially during bulkhead door replacement projects involving custom installations.
Can a cellar door be used as a legal egress?
A cellar door can be used as a legal egress only if it meets specific building codes. These include minimum size requirements for the opening, easy accessibility from the inside without tools, and a clear exit path to the outside. The door must also open fully and stay open without assistance. If your cellar door is part of a finished basement, legal egress is required in most areas for bedrooms or living spaces. Using basement bulkhead doors with glass panels or converting to patio doors or security doors can sometimes help meet these requirements. It’s important to work with a licensed contractor familiar with code compliance to ensure your entry door installation meets safety laws.
What are the best materials for coastal or humid climates?
In coastal or humid regions, choosing the right materials is essential to prevent rust and decay. Fiberglass doors are a top pick because they resist warping, moisture, and salt corrosion. Composite doors and composite wood doors also perform well in these environments. If you prefer wood doors, make sure they are sealed properly and protected with weather-resistant paint or stain. Avoid untreated solid wood, which can absorb moisture and swell. Steel doors can work too, especially with powder coating or galvanized finishes. These resist rust and provide strong security. Talk to a professional door installer for expert advice and materials that match your climate and foot traffic needs.
How long does installation typically take?
Bulkhead door installation usually takes 4 to 8 hours for standard setups. However, more complex installations or custom installations can extend to one or two days. The installation complexity depends on whether the old door needs removal, if concrete or load-bearing wall work is involved, or if drainage systems must be added. Some projects may require additional labor if structural changes or permits are needed. Smaller jobs, such as replacing flat cellar doors with similar units, are faster and more affordable. Always request an accurate quote with a timeline based on your specific entry doors. A reliable full-service door installation company will outline labor hours, scheduling, and any prep work needed.
What kind of maintenance do cellar doors need annually?
Yearly maintenance helps your cellar door last longer and function safely. Start by inspecting for rust, cracks, or warping. Clean off debris and check for water pooling near the exterior wall. Lubricate hinges and make sure the door opens and closes easily. Reseal or repaint wooden bulkhead doors and touch up metal ones with rust-inhibiting paint. Examine weatherstripping and seals—replace them if worn. Remove leaves or buildup in nearby drains to keep water from backing up. Check fasteners, especially if there’s heavy foot traffic. If your door includes Storm doors, Pocket doors, or Barn door installation features, check any sliding parts too. Regular attention avoids costly common repairs or bulkhead door quote surprises later.
