Door Trimming for New Carpet: What You Need to Know
Door Trimming for New Carpet: What You Need to Know
So you've just had beautiful new carpet laid throughout your Christchurch home. It looks amazing, feels luxurious underfoot... and now your doors won't close!
Don't panic - this is completely normal and something I deal with regularly here in Northcote and all around Christchurch.
Why Do Doors Need Trimming After New Carpet?
New carpet and underlay adds height - typically 10-20mm depending on what you've chosen. If your doors were already close to the floor, they simply don't have enough clearance anymore.
The good news? This is a straightforward job for an experienced handyman. The bad news? Doing it wrong can ruin your door.
How to Tell If Your Door Needs Trimming
Here are the telltale signs:
- The door scrapes or sticks when you try to open or close it
- You can hear it dragging on the carpet
- The door won't close fully - it hits the carpet before reaching the frame
- There's visible carpet wear where the door makes contact
- The door is hard to move and requires extra force
DIY vs Professional Door Trimming
Can You Do It Yourself?
Technically, yes. But should you? Here's what you need:
Tools required:
- Circular saw or hand plane
- Sharp chisels
- Straight edge and marking tools
- Workbench or sawhorses
- Safety equipment
- Ability to remove and re-hang doors
- Precise measuring and cutting
- Understanding of door swing and clearances
- Experience with finishing work
Why Hire a Professional?
In my 43 years of experience, I've seen countless DIY door trimming attempts go wrong:
- Cut too much: Door now has a huge gap and looks terrible
- Uneven cuts: Door wobbles or doesn't seal properly
- Wrong angle: Door hits the frame instead of closing smoothly
- Damage to door: Chips, splinters, or cracks
- Hinge issues: Door won't hang properly after reinstallation
- Understanding the door's swing arc
- Maintaining proper clearances
- Preserving the door's integrity
- Ensuring smooth operation
- Making it look professional

How Much Clearance Does a Door Need?
The standard clearance between a door and carpet is:
- Interior doors: 3-5mm
- Exterior doors: 5-10mm (to accommodate weatherstripping)
Common Door Trimming Scenarios in Christchurch
Solid Wood Doors
These are the easiest to work with. I can plane or cut them cleanly, and they respond well to adjustments.Hollow Core Doors
These require more care - you can't cut too much or you'll expose the hollow interior. Usually limited to 10-15mm maximum.Fire Doors
These have specific regulations about how much can be trimmed. I always check the manufacturer's specifications.Older Christchurch Homes
Many homes in St Albans, Richmond, and other established suburbs have doors that have been adjusted multiple times over the decades. These need extra care to ensure there's still enough material to work with.Cost of Door Trimming in Christchurch
While every job is different, here's what you can typically expect:
- Single door trim: $80-120
- Multiple doors: Discounted rate per door
- Hinge adjustment only: $40-60
- Complex jobs: Assessed individually
Door Trimming Tips from 43 Years of Experience
- Always remove the door - trying to cut it in place is asking for trouble
- Measure twice, cut once - the old saying is still true
- Use sharp tools - dull blades cause splintering and rough cuts
- Consider the swing - the door needs clearance throughout its entire arc
- Don't over-trim - you can always take more off, but you can't put it back
When Door Trimming Isn't the Answer
Sometimes trimming isn't the best solution:
- Door is already too short - might need a new door
- Frame is out of square - structural issue needs addressing
- Hinge problems - might need hinge replacement or adjustment
- Foundation settling - could indicate bigger issues
