How much does it cost to replace windows in Chapelizod?
Window replacement costs in Chapelizod typically range from €600–€1,200 per window, depending on size, material, and energy rating. For a standard 3-bedroom semi-detached home in Chapelizod, a full-home window replacement with energy-efficient A-rated uPVC windows will generally come to €12,000–€18,000. At Airtight Window Systems, we provide free in-home consultations and detailed quotes within 24 hours, so you know exactly what your project will cost before making any commitment.
How much does a new front door cost in Chapelizod?
New front door installation in Chapelizod 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 Chapelizod 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.
Is it worth getting triple glazed windows in Chapelizod?
Yes — triple glazed windows deliver real benefits for Chapelizod 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 Chapelizod households:
- Better heat retention through Ireland’s cold, damp winters
- Reduced condensation — a common issue in the older housing stock found across the Chapelizod area
- Superior noise reduction, particularly valuable for homes near busy roads in Chapelizod
- Higher resale value as buyers increasingly expect A-rated windows
- Lower carbon footprint and improved BER ratings
How long does it take to install new windows in a Chapelizod home?
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.
Do I need planning permission to replace windows in Chapelizod?
In most cases, no planning permission is required to replace windows in Chapelizod, 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 Chapelizod area, we can advise you during your free consultation.
What is the process for replacing windows in my Chapelizod home?
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 Chapelizod 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 Chapelizod 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.
Are A-rated windows worth it in Chapelizod?
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 Chapelizod families, this means lower energy bills and a noticeably more comfortable home throughout the year.
How long do uPVC windows last in Chapelizod?
uPVC windows typically last 20–35 years in Ireland with minimal maintenance, making them excellent long-term value for Chapelizod 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.
