If you live in an older home with sagging plaster on your walls and ceilings, it can be fixed. Many older houses have plaster walls and ceilings with wood lath for a base. The wood lath was installed with gaps, called keys, between each piece of lath. The plaster was forced between spaced lath, and this keying action held the plaster in place.
As plaster ages, these keys may break away from the lath, and the plaster coating can come loose and sag away from the lath. Sagging is usually obvious. If you have sags in a plaster ceiling, press upward on the area with the flat of your hand. If the plaster feels spongy or gives under your hand pressure, it's a sign that the key strength has been lost. If it's not repaired, the plaster ceiling can collapse.
Whether the sagging plaster needs to be patched or replaced depends on the extent of the damage.
If the sagging is severe, meaning that it's hanging an inch or more away from the lath base, or if it covers a large portion of the ceiling, your best bet is to have the old plaster removed and replaster the ceiling, or have it overboarded.
When walls or ceilings are badly pitted with small cracks, bumps, holes, or water damage, they benefit greatly from a double skim of finishing plaster. Using a double skimming process allows for a great wall surface and produces a perfect decorating finish.
When walls are in good condition but still need to be freshened up, we use a soft plaster filler to eliminate any imperfections like small holes, cracks, or marks. The entire wall or ceiling is sanded to give a flat clean surface for a great finish. This method is very popular as it is less costly in comparison to the double plaster skim, but can produce a similar finish after painting.

A large percentage of our work is in repairs to tired, old plasterwork including lath & plaster & mortar backing coats which over time can fail. This often happens due to weak mixes,structural movement, impact - such as nailing fixtures/drilling etc and water /element penetration or rising damp.

When you plaster has been damaged by damp or water we can fix the damage by stripping the plaster off the wall to above the level of the damp, then treating the bare stone with 3 layers of liquid damp proof membrane. This is then left for 12 hours to dry then given a coat of cementone stabilising primer. Once that is all complete, the wall is then bonded to the correct depth of the existing wall and finally skimmed to give a smooth finish.
