Home Renovation Process Ireland: What To Expect From Start To Finish.

Understanding The Home Renovation Process In Ireland

One of the biggest concerns homeowners have before starting a renovation is understanding exactly what happens once construction begins.

Many people imagine new kitchens, beautiful finishes and completed spaces, but every successful renovation starts much deeper than that. In many cases, the majority of the work takes place behind the walls, beneath the floors and within the structure itself.

A high-quality renovation is not simply replacing finishes. It is often the complete rebuilding and upgrading of the home to modern standards.

Understanding the home renovation process in Ireland helps homeowners prepare for every stage of construction, from initial planning and demolition through to structural works, insulation upgrades, new floor construction, kitchens, finishes and final handover.

Stage 1: Strip-Out & Demolition

Before improvements can begin, the property is typically stripped back to its structural shell.

This may include:

• Removal of existing kitchens

• Removal of bathrooms

• Removal of floor coverings

• Removal of internal doors

• Removal of ceilings

• Removal of non-structural walls

• Removal of old heating systems

• Removal of outdated wiring and plumbing

Many homeowners are surprised by how much of the house is removed during this stage.

For older homes, it is often the only way to properly inspect the building and ensure hidden defects are addressed.

Stage 2: Structural Alterations

Once the property has been stripped out, structural works begin.

This can include:

Open Plan Layouts

Many renovations involve removing internal walls to create:

• Open-plan kitchens

• Larger family spaces

• Better flow between rooms

• Improved natural light

To achieve this safely, structural steel beams are often installed.

Structural Works May Include:

• Steel beam installation

• Structural columns

• Foundation upgrades

• Wall removals

• Chimney modifications

• Roof strengthening

This stage forms the backbone of the renovation.

Stage 3: Floor Upgrades & New Floor Construction

In older properties, existing floors are often unsuitable for modern energy performance standards.

It is common to remove existing floor slabs completely.

A new floor build-up may include:

Typical New Floor Construction

1. Excavation of existing floor

2. Hardcore stone installation

3. Compaction

4. Radon barrier

5. Damp-proof membrane

6. High-performance insulation

7. Underfloor heating pipework

8. Reinforced concrete floor slab

9. Levelling screed

10. Final floor finish

This dramatically improves:

• Energy efficiency

• Comfort

• Thermal performance

• Moisture control

Many homeowners are shocked by the amount of work involved beneath the finished floor.

Stage 4: Drainage & Underground Services

Before floors are poured, underground services are upgraded.

This can include:

• New foul drainage

• Surface water drainage

• Water mains

• Heating pipework

• Electrical ducting

• External service connections

This work is largely hidden once completed but is critical to the long-term performance of the property.

Stage 5: Insulation & Airtightness Upgrades

Modern renovations focus heavily on energy efficiency.

Depending on the property, upgrades may include:

Floor Insulation

Typically installed beneath the new concrete floor slab.

Wall Insulation

May involve:

• Internal insulation systems

• External insulation systems

• Cavity wall upgrades

Roof Insulation

Often upgraded to modern standards.

Airtightness Measures

Including:

• Membranes

• Seals

• Service penetrations

• Window detailing

These improvements significantly reduce heat loss and improve comfort levels.

Stage 6: New Windows & External Doors

Many renovation projects include complete replacement of windows and doors.

Benefits include:

• Improved thermal performance

• Reduced noise

• Better security

• Improved aesthetics

Options may include:

• Triple glazing

• Aluminium systems

• Composite doors

• Architectural glazing

• Large sliding doors

Stage 7: First Fix Plumbing & Heating

This is where the new home's systems begin to take shape.

Works may include:

Heating

• Air-to-water heat pumps

• Underfloor heating

• New radiators

• Zoned heating controls

Plumbing

• New water pipework

• New waste pipework

• Pressurised systems

• Hot water cylinders

All systems are installed before walls and floors are finished.

Stage 8: First Fix Electrical

The electrical system is installed throughout the property.

This may include:

• Complete rewiring

• New consumer board

• Data cabling

• Security systems

• Smart home wiring

• External lighting

• EV charging preparation

At this stage, only cables and back boxes are visible.

Stage 9: Extension Construction (Where Applicable)

Many homeowners combine renovations with extensions.

A typical extension involves:

Groundworks

• Excavation

• Foundations

• Drainage

Structure

• Blockwork

• Timber frame

• ICF construction

Roofing

• Flat roofs

• Pitched roofs

• Roof lights

Structural Steel

Often required for open-plan layouts connecting old and new spaces.

Stage 10: Plastering & Internal Finishes

This is when the property begins to resemble a home again.

Works include:

• Plaster boarding

• Skimming

• Ceiling finishes

• Bulkheads

• Feature details

The transformation becomes visible very quickly at this stage.

Stage 11: Second Fix Carpentry & Joinery

One of the most exciting stages for homeowners.

This includes:

• Internal doors

• Skirting

• Architraves

• Staircases

• Wall panelling

• Bespoke joinery

• Fitted furniture

This is where the personality of the home begins to emerge.

Stage 12: Kitchens & Bathrooms

The installation of kitchens and bathrooms is often one of the biggest milestones.

This may include:

Kitchens

• Cabinetry

• Stone worktops

• Appliances

• Feature lighting

Bathrooms

• Bathrooms Tiling

• Sanitaryware

• Showers

• Bespoke storage

These spaces have a significant impact on both property value and daily living.

Stage 13: Flooring & Decoration

Final finishes are installed throughout the property.

Including:

• Engineered timber flooring

• Large format tiling

• Carpets

• Painting

• Decorating

Attention to detail becomes increasingly important during this stage.

Stage 14: Snagging & Final Handover

Before completion, every area of the property is inspected.

Items reviewed include:

• Doors

• Joinery

• Decoration

• Lighting

• Heating systems

• Plumbing systems

• Appliances

Any minor defects are addressed before final handover.

The Reality Of A Renovation

A successful renovation is often 70% hidden work and 30% visible finishes.

The insulation beneath the floor, the drainage below the ground, the structural steel within the walls, and the upgraded services behind the plaster are what ultimately determine how the property performs for decades to come.

At Alvora, we focus not only on how a home looks when completed, but how it performs, feels, and functions long after construction is finished.
