Drylining a Victorian terrace: walls, lath ceilings and old brick

How Victorian houses differ

Most UK houses built before about 1920 have solid brick external walls, usually 225 mm thick, with no cavity. Internally, walls were plastered with lime, and ceilings and many partitions were lath and plaster: thin timber strips nailed to joists or studs, coated in lime plaster mixed with hair.

These materials move, flex and let moisture pass through. Modern gypsum plaster and plasterboard are more rigid and less forgiving of damp. That does not rule drylining out, but it does mean the method has to suit the wall rather than the other way round.

Lath and plaster ceilings: overboard or replace?

Overboarding avoids the enormous mess of pulling down a lath ceiling, which releases decades of dust and debris. The new board must be fixed through into the joists with longer screws, never just into the laths. Taking it down is the right call when the plaster has lost its grip on the laths, because adding board weight to a failing ceiling only delays the problem.

Internal walls and partitions

Original lath partitions can be overboarded in the same way, or stripped back to the studs and boarded if you are rewiring, replumbing or want better sound insulation. Brick internal walls with blown or crumbling plaster can be dot-and-dabbed once loose plaster has been removed, provided they are dry.

Victorian walls are rarely straight or plumb. Dot-and-dab copes with modest variation, but where walls are badly out, a metal or timber framed lining set out true gives a far better result than trying to pack the dabs out.

Damp and breathability

The biggest risk in an old terrace is bonding board directly to a solid wall that gets damp. Common causes are blocked gutters, leaking downpipes, high outside ground levels, bridged or failed damp-proof courses, cement render or cement pointing that traps water, and lack of ventilation.

• Find and fix the source of damp before any lining
• Let the wall dry out, which can take months after a serious problem
• Keep sound lime plaster rather than hacking it off by default
• On damp-prone walls, consider a framed lining with a gap behind it
• Ask about breathable insulation options if insulating external walls
• Avoid cement-based renders and gypsum patching on lime backgrounds

Party walls and noise

Terraces share party walls with neighbours, and older ones can be thin or have gaps around chimney breasts and joist ends. An independent stud lining with mineral wool and acoustic board, separate from the party wall, usually gives a better result than bonding board straight onto the brick.

Work on your side of a party wall, such as lining or fixing into it, does not normally need a party wall notice, but cutting into the wall to insert beams or chasing deeply into it can. If in doubt, take advice before starting.

Chimney breasts are a particular weak spot. Where a breast has been removed on one side, or flues are shared, sound can travel through the old flue and around the breast. Sealing flues that are no longer used, with ventilation kept where needed to prevent damp, and lining the alcoves carefully helps.

Preserving character

• Measure and record cornices, picture rails and skirting profiles before work starts
• Allow for extra depth at window reveals and door linings, which may need extending
• Keep original features where you can and board up to them neatly
• Check whether the house is listed or in a conservation area, as consent may be needed for internal changes to listed buildings

Order of works in a period renovation

Drylining sits in the middle of a period renovation, so getting the sequence right saves both money and mess. Roof, gutters and external repairs come first, so the walls can start drying. Then structural work, chimney breast changes and any timber treatment, followed by first fix electrics and plumbing.

• External repairs and damp causes fixed
• Structural work and opening up done
• First fix electrics, heating and plumbing
• Ceilings boarded or overboarded before walls
• Walls lined, insulated or boarded
• Taping, jointing or skimming
• Joinery, second fix and decoration

Boarding ceilings before walls lets the wall boards support the ceiling edges and gives a neater junction. Leave skirting, architraves and cornice repairs until the boards are finished.
