Why Internal Doors Matter
You might not think about your internal doors every day, but they play a huge role in the look, feel, and function of your home. Here's why they’re so important:
- Privacy: Doors separate spaces, giving you personal areas when needed.
- Noise Reduction: Good doors muffle sound, helping homes feel more peaceful.
- Energy Efficiency: Well-fitted doors can help trap heat, making your home more energy-efficient.
- Style & Cohesion: Internal doors help tie the design of your house together. The right style elevates your whole interior.
In short: your doors are doing more than you think. So when they start to fail, it’s a big deal.
How Long Do Internal Doors Last?
The lifespan of internal doors varies depending on material, usage, and environment. Here’s a rough idea:
- Solid Wood Doors: 20–60 years if properly maintained
- Engineered Wood Doors (like MDF): 10–30 years
- Hollow Core Doors: 10–20 years
- Glass-Panel Doors: 15–30 years, depending on framing quality
- Fire Doors: Should be regularly inspected and replaced when any fault appears, regardless of age.
Heavy use, high humidity, or poor installation can shorten a door’s lifespan dramatically.
Top Signs You Should Replace Your Internal Doors
1. Visible Damage
If your doors have cracks, splits, dents, or warping, they aren’t doing their job anymore — and they’re probably dragging down the appearance of your home. Damage like this isn’t just cosmetic; it can also affect insulation and safety.
2. Sticking or Swinging Open
A door that sticks when you open it, or swings open without latching, is a major red flag. It usually means:
- The door has warped
- The hinges have shifted
- The frame has settled out of shape
Sometimes, minor issues can be fixed, but persistent problems often mean it’s time for a full replacement.
3. Outdated Style
Even if your doors work fine, they may no longer match your home’s look. Old-fashioned paneled doors, yellowed pine, or worn-out hardware can make your interiors feel tired and dated.
New doors can instantly modernize your home and even boost its value.
4. Drafts or Temperature Changes
If you feel a draft coming through closed doors, that’s a big sign they’re not sealing properly anymore. This can lead to higher energy bills and uncomfortable rooms.
Modern doors offer far better insulation properties — replacing old ones can make a real difference.

Can you hear every footstep, conversation, or TV from the next room? New doors, especially solid or acoustic-rated ones, provide far better soundproofing than older models.
If privacy is important to you, replacing your internal doors could be the answer.
6. Damage After Home Renovations
Had building work done? Settling foundations, updated floors, or even just moving walls can leave your internal doors hanging awkwardly.
In many renovation cases, it’s actually easier and cheaper to replace doors than to endlessly try to re-hang old ones.
7. Fire Safety Concerns
Fire doors in particular must be replaced immediately if they are damaged or fail inspections. A compromised fire door can no longer provide protection in an emergency.
When You Might Not Need a Full Replacement
Sometimes, simple issues don’t call for a brand-new door:
- Squeaky Hinges: A little oil might fix it.
- Cosmetic Scratches: Light sanding and refinishing can work wonders.
- Loose Handles: Tightening or replacing hardware is easy.
If your door is basically sound, a repair or refurbish could be enough. But for significant structural problems, new doors are the smart move.
Choosing Your New Internal Doors
Once you've decided to replace your internal doors, you’ve got a world of options. Here’s how to choose:
Material Choices
- Solid Wood: Classic, durable, and luxurious. Perfect for a timeless look.
- Engineered Wood: Affordable and stable. Good for most households.
- Glass: Great for maximizing light, especially in darker homes.
- Fire Rated: Required in some homes for safety (especially in multi-story properties or renovations).
Styles to Consider
- Panelled Doors: Traditional and versatile.
- Flush Doors: Sleek and modern.
- Glazed Doors: Bright and contemporary, ideal for communal spaces.
- Bespoke Doors: Custom doors let you match your exact taste and room dimensions.
Colours and Finishes
- White Primed: A modern, clean look that can be painted any colour.
- Oak Veneer: Warm and natural.
- Walnut Veneer: Rich, luxurious and stylish.
- Painted Bold Colours: Great for a statement interior.
Consider how your choice fits with flooring, wall colours, and furniture.
The Cost of Replacing Internal Doors
Prices vary massively depending on material, style, and brand. As a rough guide:
- Budget doors (hollow core, primed): £50–£120
- Mid-range doors (solid core, stylish designs): £120–£300
- Premium doors (solid timber, bespoke designs): £300–£1000+
Factor in installation costs too: around £50–£100 per door depending on complexity.
If you need fire doors, specialist glass, or oversized doors, expect higher costs.
Installation: DIY or Professional?
Hanging a door properly requires real skill. For best results:
- Hire a professional joiner
- Ensure old frames are checked or replaced if necessary
- Make sure the door opens smoothly and fits perfectly
DIY is possible if you're confident, but a poorly hung door can waste the money you saved.
Frequently Asked Questions About Replacing Internal Doors
Can I just replace the door leaf without changing the frame?
Yes, if the frame is still square and in good condition. However, new doors may not always perfectly fit old frames — slight trimming is often needed.
How many doors should I replace at once?
If several doors look tired, it's often more cost-effective (and stylistically consistent) to replace them all at once. Many suppliers offer bulk discounts.
Do I need planning permission to replace internal doors?
No — internal doors are considered a minor, permitted improvement. The exception is listed buildings, where you may need permission for any significant changes.
Are white primed doors good replacements?
Absolutely! White primed doors offer a fresh, neutral look, ready for you to paint. They’re cost-effective and fit almost any interior style.
How do fire doors differ from standard internal doors?
Fire doors are thicker, heavier, and have special seals to prevent smoke and fire spreading. They are legally required in certain homes (like three-storey houses).
Final Thoughts: Don't Underestimate the Power of New Doors
Replacing your internal doors isn’t just a practical move — it’s a major style upgrade.
Whether you’re chasing better insulation, smoother operation, or simply a fresher look, new doors offer big rewards for a relatively small investment.
Key takeaways:
- Don’t ignore damaged or sticking doors
- Choose the right material and style for your home
- Invest in professional fitting for the best results
- Replacing multiple doors at once gives the most cohesive look
A few well-chosen internal doors can completely transform your home’s feel — making it quieter, warmer, safer, and more beautiful.
