Compare demolition 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.

Demolition FAQs
Internal wall removal costs €800 to €2,000 for a non-load-bearing wall and €2,000 to €5,000 for a load-bearing wall (including structural steel beam and making good). Garage demolition costs €2,000 to €4,000. Full house demolition costs €15,000 to €35,000 depending on size, construction type, access, and waste disposal. Asbestos removal, if needed, adds €2,000 to €10,000 depending on extent.
Demolition of a habitable house generally requires planning permission from your local authority. Demolition of non-habitable structures (derelict buildings, sheds, garages) may be exempt, but check with your local authority. Internal demolition (removing walls within your home) does not require planning permission. If your property is a protected structure, any demolition, even internal, may require planning.
You cannot reliably determine this yourself. A structural engineer must assess the wall by examining its position in relation to the floor and roof structure above. Load-bearing walls typically run perpendicular to the floor joists and support the weight of the floors and roof above. However, there are exceptions, and getting it wrong can cause structural collapse. A structural engineer's assessment costs €200 to €500 and is essential for any wall removal.
Homes built before the mid-1990s in Ireland may contain asbestos in various materials: cement roof slates, floor tiles, soffit boards, pipe lagging, water tank insulation, and textured ceiling coatings (Artex). Asbestos is not dangerous if undisturbed, but demolition disturbs it, releasing fibres that cause serious lung disease. A licensed asbestos surveyor can test suspected materials. If asbestos is confirmed, a licensed removal contractor must handle it before demolition proceeds. The HSA maintains a register of licensed contractors.
Internal wall removal takes 1 to 3 days depending on the wall size and whether structural steel is needed. Garage demolition takes 1 to 2 days. Full house demolition takes 3 to 7 days for the demolition itself, plus time for site clearance and waste removal. Asbestos removal adds 1 to 5 days depending on the extent. Allow additional time for structural engineer assessments, asbestos surveys, and any required planning permission.
Demolition waste must be segregated into categories: concrete and masonry (can be crushed and reused), timber, metals (typically recycled), and general waste. All waste must be disposed of at licensed waste facilities. Your contractor should provide waste transfer documentation proving lawful disposal. Illegal dumping of demolition waste carries significant fines. A reputable contractor includes proper waste management in their service.
