23 Years of Experience Working with Homeowners Across County Kildare
Why Kildare Homeowners Choose Airtight
Since 2003, we’ve been the family-owned window and door specialists Kildare homeowners trust when they want the job done right the first time. From established estates in Naas, Newbridge, and Maynooth to period properties near Kildare town centre, newer developments in Celbridge and Leixlip, and larger detached homes along the M7 and N7 corridors, County Kildare has one of the most varied property mixes in Leinster — ranging from 1980s and 90s commuter belt builds overdue a full window replacement, to older rural properties along the Curragh plains where the flat, open landscape brings persistent cold westerly winds that accelerate wear on older frames. The county’s proximity to Dublin also drives strong demand for upgrades that improve both energy performance and kerb appeal, and with many homes still falling well short of today’s energy efficiency standards, we’ve been delivering the right solution to every property type across County Kildare for over two decades.

How much does it cost to replace windows in Kildare?
Window replacement costs in County Kildare typically range from €600–€1,200 per window, depending on size, material, and energy rating. For a standard 3-bedroom semi-detached home in Kildare, expect to pay €12,000–€18,000 for a full-home replacement with energy-efficient A-rated uPVC windows. 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 committing.
How much does a new front door cost in Kildare?
A new composite front door in Kildare starts from €1,800 plus VAT for a single door, rising to €3,600 plus VAT depending on the style, glass design, and any adjoining side panels. Our Palladio Composite doors are manufactured in Ireland, come with a 12-year guarantee, and are available in 20+ colours — making them a popular choice for homeowners throughout County Kildare looking to upgrade both kerb appeal and security in one go.
Is it worth getting triple glazed windows in Kildare?
Yes — triple glazed windows deliver clear benefits for Kildare homes. The county’s flat, open landscape and exposure to cold westerly winds off the Curragh mean older single and double glazed windows are under real pressure, particularly during winter months when heating costs are at their highest. Triple glazing makes a noticeable and lasting difference for homes across Naas, Newbridge, Kildare town, and the wider county.
Five years ago, 90% of windows installed by Airtight 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 Kildare households:
- Better heat retention during Ireland’s cold, damp winters
- Reduced condensation — common in older Kildare properties built before modern energy standards
- Superior noise reduction, particularly useful for homes near the M7, N7, or busier routes through Naas and Newbridge town centres
- Higher home 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 Kildare home?
Window and door installation in a 3-bed semi with 8–10 windows and two doors takes 3 days to complete. This includes all associated plasterwork, perimeter sealing, and removal of waste as standard.
Do I need planning permission to replace windows in Kildare?
Generally, no planning permission is required to replace windows in County Kildare if you’re replacing like-for-like — same size, style, and position. That said, Kildare has a number of protected structures, including properties in Kildare town centre, parts of Naas and Athy, and various heritage buildings across the county, where changes to fenestration may attract scrutiny. If your property is a protected structure, or if you’re significantly changing window size or style, planning permission may be required. We’ll advise you on this during your free consultation.
What is the process for replacing windows in my Kildare home?
Our window replacement process is designed for minimal disruption and maximum transparency:
Step 1: Free In-Home Consultation (30–60 minutes) — A member of our sales team visits your Kildare 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 including window specifications, installation timeline, total cost breakdown, and warranty details. We also provide a free energy audit showing projected heating bill savings.
Step 3: Order & Manufacturing (3–4 weeks to 6–8 weeks) — 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 to minimise disruption — particularly important as more Kildare households work from home. Installation includes removal and safe disposal of old windows/doors, frame preparation, precise fitting, all associated plasterwork, and perimeter sealing.
Step 5: Final Inspection — We conduct a thorough inspection with you, demonstrate how to operate the new windows and doors, and hand over spare keys. Care for the home we’re working in is paramount — our fitters are regularly complimented for leaving properties spotless.
Are A-rated windows worth it in Kildare?
Yes, we’ve been fitting A-rated windows for the past 10–15 years, and they are now a standard part of our offering. Even a double glazed A-rated window can reduce heat loss by 40% compared to older single glazing, with further improvements available through triple glazing. This translates to lower energy bills and a noticeably warmer, more comfortable home for Kildare families throughout the year — particularly valuable in older properties across the county that were never designed with modern energy efficiency in mind.
How long do uPVC windows last in Kildare?
uPVC windows last 20–35 years in Ireland with minimal maintenance, making them excellent long-term value for Kildare homeowners. Lifespan depends on quality, installation, weather exposure, and basic upkeep. In a county as exposed as Kildare — where the open plains and prevailing westerlies mean persistent wind and temperature swings — choosing a quality product from a certified installer is especially important. Inferior products degrade faster when exposed to these conditions. uPVC can also be recycled at the end of its lifespan to maximise sustainability.
