Compare plastering & rendering professionals in Castleknock. Free quotes, no obligation.
Castleknock is dominated by large, well-maintained family homes built from the 1980s to 2000s in estates like Castleknock Park, Beechpark, Carpenterstown, and Diswellstown. Housing is predominantly detached and semi-detached, three to five bedrooms, with good-sized gardens. Many homes are now 20 to 30 years old and reaching the point where boiler replacement, window upgrades, kitchen renovations, and energy retrofits are needed. The Phoenix Park boundary creates a distinctive western edge. Some older housing exists near the village centre.
Managed by Fingal County Council. A well-established, affluent family area with high property values (€500k to €1m+). The mature housing stock creates consistent demand for mid-life upgrades: boiler replacement, attic insulation top-ups, window replacement, kitchen and bathroom renovations, and garden landscaping. The area is relatively sheltered with good tree cover. Access for trades is generally good with driveways and parking. The established nature of the area means less new-build activity and more renovation and extension work.

Plastering & Rendering FAQs
Skimming a single room (walls and ceiling) costs €300 to €600 depending on room size. A full house re-skim for a three-bed semi costs €2,500 to €5,000. Full re-plastering (back to block) costs roughly double. External rendering costs €40 to €70 per square metre for traditional render, €50 to €90 for silicone or one-coat systems. A full house external render (three-bed semi) costs €6,000 to €12,000 including scaffolding.
Skimming one room takes a day. A full house re-skim takes 4 to 7 days. Full re-plastering (including removal of old plaster) takes 7 to 14 days for a three-bed semi. External rendering takes 1 to 3 weeks depending on the house size and system used. Drying time of 2 to 4 weeks after completion is needed before painting.
New plaster typically takes 2 to 4 weeks to dry fully, depending on room ventilation, temperature, and humidity. You can tell plaster is dry when it changes from a dark colour to a uniformly light pink or white. Do not attempt to speed up drying with direct heat (radiators against the wall, heaters aimed at the plaster) as this causes cracking. Good ventilation (windows cracked open) is the safest approach.
Skimming applies a thin (2-3mm) coat of finishing plaster over an existing sound surface (plasterboard, old plaster). It creates a smooth finish ready for painting. Re-plastering involves removing the old plaster back to the blockwork, applying a new scratch coat (8-12mm), and then skimming. Re-plastering is necessary when old plaster is blowing (detaching from the wall), extensively cracked, or damp-damaged.
Hairline cracks in plaster are common and usually caused by natural building settlement, temperature fluctuations, or slight movement in the structure. They are cosmetic and easily filled. Larger cracks or cracks that reappear after filling may indicate structural movement, which should be assessed by an engineer. Cracking in new plaster usually means it dried too quickly (heated too fast) or was applied too thickly in one coat.
If walls are in poor condition (cracks, bumps, blown plaster, damp staining), replastering makes a noticeable difference to how buyers perceive the property. A freshly plastered and painted house feels clean, well-maintained, and move-in ready. A full re-skim of a three-bed semi costs €2,500 to €5,000, which is a modest investment relative to the improvement in first impressions.
