Interior Trim and Door Frame Replacement Costs

Interior trim replacement is one of the most common carpentry jobs in UK renovation projects, typically arising when original boards are damaged, rotted, or need updating to suit a refreshed aesthetic. In properties that have passed through multiple owners, it is common to find a patchwork of mismatched profiles across rooms, making a complete update both practical and visually coherent. The scope of work can range from a single door opening to every room in the house, and costs vary accordingly.

Key points

• Door linings (the structural casing fixed to the masonry or stud) and architrave (the decorative moulding covering the gap between lining and wall) are distinct components and may be quoted separately by a carpenter.
• Moisture-resistant (MR) grade MDF must be specified for trim in bathrooms, utility rooms, and kitchens — standard MDF swells and fails when exposed to prolonged moisture.
• Matching period moulding profiles in pre-1919 properties often requires specialist timber suppliers or custom routing, which can add 30–60% to standard material costs.
• FENSA certification applies to glazed window units, not interior door frames; it is not required when replacing door linings or architrave.
• Removing skirting boards bonded with construction adhesive as well as nails can damage the plaster beneath, potentially adding £50–150 per room in plastering costs before new boards are fitted.

What does interior trim replacement include?

Interior trim covers the timber or composite elements that finish wall junctions and door openings throughout a home. The main components are:

• Skirting boards: horizontal boards running along the base of walls, typically 75–150mm tall in modern properties and taller in period homes.
• Architrave: the decorative moulded trim applied around door openings on each side of the wall.
• Door linings (or door frames): the structural casing fitted to the rough opening in the wall into which a door is hung.
• Door stop: the thin rebate strip within the lining against which a closed door rests.
• Window boards: the sill board across the bottom of a window opening, sometimes included in a trim quote.

A standard renovation quote may bundle skirting, architrave, and lining replacement together per room or per door opening. Clarifying exactly what each quote covers before accepting is worth doing, particularly for period properties where like-for-like profile matching may be required.

Indicative costs for interior trim and door frames in the UK

The following figures are indicative UK costs, last reviewed 2026-05-06. Quotes vary by region, material choice, access conditions, and the extent of existing plaster damage.

Indicative UK costs, last reviewed 2026-05-06. Prices vary significantly by region, material grade, profile complexity, and access. Always request itemised quotes from at least two carpenters.

What affects the price?

Several factors can push a quote up or down from the indicative ranges above.

Material choice: MDF is the most common and economical option for painted trim. Hardwood (oak, tulipwood) costs more but suits high-traffic areas or properties where the finish will be stained. Softwood (pine or redwood) sits between the two in price.

Profile complexity: Ogee, torus, and chamfered skirting profiles are widely stocked, but unusual or deeply detailed mouldings found in Victorian or Edwardian houses may need to be custom-profiled from solid timber, adding both material cost and lead time.

Existing damage: Old adhesive residue, crumbling lime plaster, and uneven walls all take additional preparation time and increase the labour component of a quote.

Number of openings: Carpenters typically offer a better per-unit rate when replacing trim across an entire property rather than a single room.

Access: Staircases and hallways with high ceilings may require specialist access equipment, which adds to the day rate.

A worked example: 1930s semi-detached renovation in the Midlands

Consider a three-bedroom 1930s semi-detached property undergoing a full internal refresh. The property has:

• Eight door openings, each requiring architrave on both sides of the wall
• Approximately 65 linear metres of skirting across all rooms
• A mix of original 1930s ovolo-profile skirting and plain 1980s boards fitted during a previous renovation
• One bathroom requiring moisture-resistant materials throughout

A carpenter quoting for the full property might break the estimate down roughly as follows:

• Skirting replacement (65m at approximately £18/m): approximately £1,170
• Architrave replacement (8 openings, both sides, at £130 per opening): approximately £1,040
• Door lining replacement (4 openings needing new linings at £220 each): approximately £880
• MR MDF upcharge for bathroom trim: approximately £60 additional
• Plastering patches in two rooms with adhesive damage: approximately £200

Estimated total: £3,200–£3,600 before decoration.

This is a worked illustration based on indicative rates only. Actual quotes for this property may differ. Soliciting two or three quotes from local carpenters will give a clearer market rate for your area and specification.

What to check before getting quotes

Use this checklist to prepare before inviting carpenters to quote:

• Measure the linear metres of skirting in each room (total wall perimeter minus door openings)
  
• Count the number of door openings and confirm whether both sides need new architrave
  
• Identify which rooms need moisture-resistant materials
  
• Check whether existing skirting is glued as well as nailed — tap along the length and listen for a solid versus hollow sound
  
• Note whether any existing moulding profiles need to be matched exactly
  
• Inspect the plaster behind a lifted section of skirting for cracks or deterioration
  
• Ask each tradesperson whether decoration (filling, sanding, and painting) is included or quoted separately
  
• Confirm whether any door linings are structural — unusual but possible in older properties with altered openings
  

When to get professional help

Most interior trim work is straightforward for an experienced carpenter, but certain situations warrant additional caution.

If a door opening has visible cracking above the lintel or a sagging head, seek a structural assessment before any trim work begins — the cause may be lintel failure rather than a cosmetic problem. If the property is listed, alterations to original period joinery may require listed building consent from your local planning authority before any removal or replacement. Lead paint is commonly found in older paint layers on pre-1960s properties; if you suspect it is present, have the paint tested before any sanding or mechanical removal. The HSE publishes guidance on lead paint safety for those carrying out renovation work.

Frequently asked questions

How long does it take to replace skirting boards in a three-bedroom house?

A carpenter typically takes two to four days to replace skirting boards throughout a three-bedroom property, depending on the number of rooms, the condition of existing plaster, and whether door frames are being replaced at the same time. Complex period profiles or significant plastering repairs can extend the timeline. Materials usually need a day to acclimatise before fitting.

What is the difference between a door lining and a door frame?

A door lining is the full casing fitted to the rough opening in the wall, including the head and two jambs, and is the element into which a door is hung. Architrave is the separate decorative moulding applied over the joint between the lining and the wall plaster. The term door frame is often used interchangeably with door lining in domestic contexts.

Do I need planning permission to replace interior door frames?

In most cases, no. Replacing like-for-like interior door frames is classed as routine maintenance and does not require planning permission. The exception is if the property is listed, in which case listed building consent may be needed for any alteration to historic joinery. Always check with your local planning authority if you are unsure.

Can I replace skirting boards without replastering?

Sometimes. If the existing plaster behind the skirting is sound, new boards can usually be fitted directly. Where old boards were bonded with adhesive, their removal can pull away the plaster face, requiring patching. A carpenter should inspect behind a sample section before quoting to give a realistic assessment of any plastering work needed.

Is MDF or hardwood better for skirting boards?

MDF is the most cost-effective choice for painted skirting in most rooms and holds a painted finish well. Hardwood is better suited to high-traffic areas or where a stained natural finish is wanted, and it is more durable under knocks and scrapes. In bathrooms and utility rooms, moisture-resistant MDF or PVC trim should be used instead of standard MDF, which swells when exposed to moisture.
