Window replacement costs in Rathcoole typically range from €600–€1,200 per window, depending on size, material, and energy rating.

New front door installation in Rathcoole starts from €1,800 plus VAT for supply and installation of a single triple glazed Composite Door, up to €3,600 plus VAT for a triple glazed Composite Door with two adjoining side-screens. Composite doors offer excellent value for Rathcoole homeowners — combining the premium appearance of timber with virtually zero maintenance, superior insulation, and multi-point locking as standard. Installations typically take one day and carry a 12-year guarantee.

Yes — triple glazed windows deliver real benefits for Rathcoole homes, especially on north-facing aspects that receive limited direct sunlight. Five years ago, 90% of windows we installed were double glazed versus 10% triple glazed. Today it’s a 50/50 split, and we expect triple glazing to overtake double glazing very soon.

Benefits for Rathcoole households:

  • Better heat retention through Ireland’s cold, damp winters
  • Reduced condensation — a common issue in the older housing stock found across the Rathcoole area
  • Superior noise reduction, particularly valuable for homes near the N7 and busy roads serving Rathcoole
  • Higher resale value as buyers increasingly expect A-rated windows
  • Lower carbon footprint and improved BER ratings

A full window and door installation in a 3-bed semi with 8–10 windows and two doors typically takes 3 days to complete. This includes all associated plasterwork, perimeter sealing, and removal and disposal of old frames as standard.

In most cases, no planning permission is required to replace windows in Rathcoole, provided you’re replacing like-for-like — same size, style, and position. Planning permission may be needed for protected structures, buildings in Architectural Conservation Areas (ACAs), or where you’re significantly changing window size or adding new openings. If you’re unsure about your specific property in the Rathcoole area, we can advise you during your free consultation.

Our process is designed to cause minimal disruption while keeping you informed at every stage:

Step 1: Free In-Home Consultation (30–60 minutes) — A member of our team visits your Rathcoole home to take measurements, discuss your preferences (style, colour, functionality), and answer any questions. No pressure, no obligation.

Step 2: Detailed Quote — You receive a comprehensive quote covering window specifications, installation timeline, a full cost breakdown, and warranty details. We also provide a free energy audit showing projected heating bill savings.

Step 3: Order & Manufacturing (3–4 weeks, or 6–8 weeks for bespoke items) — Once you approve the quote, windows are custom-manufactured to your exact measurements using premium uPVC, composite, or aluminium materials with A-rated energy efficiency.

Step 4: Professional Installation (1–3 days) — Our experienced installers arrive on schedule and agree a fitting plan with you to keep disruption to a minimum — particularly important as more Rathcoole households work from home. Installation covers removal and safe disposal of old windows and doors, frame preparation, precise fitting, all associated plasterwork, and perimeter sealing.

Step 5: Final Inspection — We carry out a thorough walkthrough with you, demonstrate how to operate your new windows and doors, and hand over spare keys. Our fitters are consistently praised for leaving properties clean and tidy.

Yes. We’ve been fitting A-rated windows for the past 10–15 years, and they’re now a standard part of every installation we carry out. Even a double glazed A-rated window can reduce heat loss by up to 40% compared to older single glazing, with additional savings available through triple glazing. For Rathcoole families, this means lower energy bills and a noticeably more comfortable home throughout the year.

uPVC windows typically last 20–35 years in Ireland with minimal maintenance, making them excellent long-term value for Rathcoole homeowners. Lifespan depends on product quality, installation standards, weather exposure, and basic upkeep. uPVC can also be fully recycled at the end of its lifespan, which is an added sustainability benefit.
