The Benefits of Choosing a Supply and Fit Door Service vs DIY
Replacing or upgrading your internal doors is one of the quickest ways to modernise your home—but when it comes to installation, many homeowners ask the same question: Should I fit the doors myself, or choose a professional supply and fit service?
While DIY may seem cheaper on the surface, door fitting requires precision, specialist tools, and experience. Even a small mistake can lead to poor alignment, sticking doors, damaged frames, or costly reordering. That’s why more homeowners across Leeds and West Yorkshire are choosing The Door Line’s professional supply and fit door service, which handles everything from accurate measurements to expert installation.
Below, we break down the key benefits of choosing a supply and fit service vs attempting DIY door installation.
1. Accurate Measurements Guarantee the Right Fit
One of the most common DIY mistakes is incorrect measuring. Doors must be measured to the millimetre—not just in width and height, but also in relation to:
-
Frame depth
-
Floor clearance
-
Squareness of the frame
-
Door stop alignment
-
Trim allowances
Even small inaccuracies can cause major fitting issues.
With The Door Line’s pre-order measurement service, a professional joiner measures your door frames accurately to ensure the doors you purchase will fit perfectly.
2. Professional Fitting Ensures Perfect Alignment
A professionally fitted internal door should open smoothly, close securely, and sit evenly within the frame. DIY fitting often results in:
-
Uneven gaps
-
Doors catching on flooring
-
Poor latch alignment
-
Over-planing or incorrect trimming
-
Hinges fitted incorrectly
Our joiners have years of experience fitting LPD internal doors—including solid core doors and fire-rated FD30/FD60 doors—which require careful handling and specialist installation knowledge.
3. Saves Time, Effort, and Stress
Fitting internal doors is much more time-consuming than people expect. The average DIY installation can take 3–6 hours per door, especially if trimming or frame adjustments are required.
In comparison, The Door Line’s professional supply & fit service provides:
-
Fast installation
-
No need to buy or hire tools
-
Zero mess left behind
-
No trial and error
You simply choose your doors—we handle everything else.
4. No Need to Invest in Specialist Tools
Proper door installation requires tools that many homeowners do not own, including:
-
Planes
-
Chisels
-
Multi-tools
-
Hole saws
-
Levels
-
Circular saws
-
Hinge jigs
Buying or renting these tools can cost more than hiring a professional in the first place.
Our joiners arrive fully equipped, ensuring safer and more precise installation.
5. Better Results With Solid Core & Fire Doors
Solid core doors and fire-rated doors are heavier, denser, and require exact fitting. DIY installation can be dangerous without the right tools or experience.
Fire doors in particular require:
-
Three fire-rated hinges
-
Correct intumescent strips
-
Approved hardware
-
Precise gaps (usually 3mm all around)
-
Compliance with regulations
Improper fitting may void fire certification.
The Door Line’s supply and fit team is fully trained to install FD30 and FD60 doors correctly and safely.
6. Reduced Risk of Damage or Costly Mistakes
DIY installations can lead to:
-
Over-trimming
-
Cracking the veneer
-
Incorrectly drilled handle holes
-
Misaligned hinges
-
Damaged frames
Once a door is trimmed incorrectly, it often cannot be fixed.
Choosing a professional installation service eliminates these risks—and ensures the door performs exactly as intended.
7. Full Responsibility From Delivery to Installation
When you choose a supply and fit service, you’re not responsible for:
-
Handling heavy doors
-
Transporting materials
-
Storing doors safely
-
Ensuring all hardware is correct
-
Managing fitting issues
The Door Line handles every step, ensuring a smooth and stress-free experience from start to finish.
8. Professional Finishing Touches
The final 5% of the job often makes the biggest visual difference. Our installers ensure:
-
Even margins around the door
-
Smooth edges
-
Correct latch engagement
-
Wobble-free handles
-
Secure hinges
-
Clean finish
These finishing touches are often missed or rushed during DIY projects.
9. Increases the Longevity and Performance of Your Doors
A professionally fitted internal door:
-
Opens and closes smoothly
-
Is less likely to warp
-
Has reduced wear on hinges
-
Offers better thermal efficiency
-
Provides improved sound insulation
This leads to longer-lasting doors and a better return on your investment.

-
Doors are measured correctly
-
