Wooden doors are a hallmark of British architecture, offering natural insulation and timeless aesthetic appeal. However, timber is a living material that reacts...
Repairing a high-quality timber door is usually more cost-effective and sustainable than a full replacement. Whether it is a sticking internal door or a weathered Victorian front door, professional carpentry can restore both functionality and security to your home.
What Does the Work Involve?
- Initial Assessment: Inspecting the door, frame, and threshold for structural integrity, alignment issues, or timber rot.
- Hardware Removal: Removing handles, locks, and hinges to allow for unobstructed repairs or resizing.
- Timber Repairs: Cutting out "soft" rotted sections and splicing in new timber (Dutchman repairs) or using high-quality wood fillers.
- Realignment: Planing the edges of the door if it is sticking due to seasonal swelling or floor movement.
- Hinge Recessing: Re-cutting or deepening hinge seats to fix "dropped" doors that scrape the carpet or frame.
- Weatherproofing: Replacing worn draught excluders and ensuring external doors meet the frame tightly to prevent heat loss.
Typical Costs
| Item | Low £ | High £ | Notes |
|---|---|---|---|
| Minor Adjustment / Planing | £80 | £150 | Fixing a single sticking door. |
| Rot Repair (Splicing Timber) | £150 | £350 | Includes materials and labour. |
| Hinge & Hardware Replacement | £100 | £200 | Labour plus mid-range ironmongery. |
| Full External Door Refurbishment | £400 | £850 | Stripping, repairing, and re-hanging. |
| Carpenter Day Rate | £250 | £450 | Varies by region (higher in London). |
Costs are influenced by the timber species; repairing a bespoke solid oak door requires more specialised skill and expensive materials than a standard pine internal door. Emergency call-outs for secured entry repairs will also command a premium.
How Long Does It Take?
- Sticking door adjustment: 45 minutes to 1.5 hours.
- Replacing hinges and realigning: 1 to 2 hours.
- Patching rot and timber splicing: 3 to 5 hours (allowing for adhesive cure times).
- Full frame and door overhaul: 1 to 2 days.
DIY or Professional?
While basic tasks like oiling hinges or light sanding are suitable for DIY, structural repairs should be left to a professional carpenter. Hanging a door or splicing timber requires precision tools and an understanding of grain direction to prevent future splitting.
Warning: If you are repairing a fire door (common in flats or between a garage and a house), any work must be performed by a competent person to ensure the door retains its fire-rating integrity under UK Building Regulations.
Choosing the Right Tradesperson
- Qualifications: Look for an NVQ Level 2 or 3 in Site Carpentry or Bench Joinery.
- Specialism: Ask if they specialise in "first fix" (structural) or "second fix" (finishing) carpentry.
- Red Flags: Avoid tradespeople who suggest using "car body filler" for large structural timber repairs instead of proper wood splicing.
- Questions to Ask:
- Do you have experience with heritage or listed building door restorations?
- Will you use dust extraction equipment while sanding indoors?
- Is the hardware you provide covered by a manufacturer’s warranty?
UK Regulations
- Part L (Conservation of Fuel and Power): External door repairs should not degrade the thermal performance of the dwelling.
- Part B (Fire Safety): Internal fire doors must have specific gaps (usually 3mm) and use intumescent strips; DIY trimming can invalidate their safety rating.
- Listed Buildings: If your home is listed, you may need Listed Building Consent for significant repairs or any changes to the door’s appearance.
Common Problems
- Seasonal Swelling: Timber expands in winter humidity; a door trimmed in winter may have excessive gaps in summer.
- Dropped Hinges: Over time, screws can pull loose from the frame, causing the door to sag and damage the floor.
- Wet Rot: Common at the base of external frames where water pools; if not cut out, it will spread through the entire structure.
- Painted-over Hardware: Years of thick paint can prevent latches and hinges from operating smoothly, often mistaken for structural failure.
Frequently Asked Questions
Can a warped wooden door be straightened?
Minor warping can sometimes be corrected by adjusting the stop beads or using tensioning bars, but severe "twisting" often requires door replacement as the timber's internal stresses are permanent.
Is it cheaper to repair or replace a door?
For standard internal hollow-core doors, replacement is usually cheaper. For solid oak, mahogany, or period front doors, repair is significantly more cost-effective than buying a like-for-like replacement.
Why does my door only stick during the winter?
Timber is hygroscopic, meaning it absorbs moisture from the damp UK winter air and expands. A carpenter can plane the specific "rubbing" points to allow for this seasonal movement.
How do I stop my door from dragging on new carpet?
A carpenter can "rise" the door by removing it and planing the bottom edge, or by installing rising butt hinges which lift the door slightly as it opens.
Can you repair a hole in a veneer door?
Small holes can be filled and painted, but because veneer is a very thin layer of real wood over a core, it is difficult to "patch" invisibly if you intend to leave the wood stained rather than painted.
