23 Years of Experience Working with Homeowners in Leixlip
Why Leixlip Homeowners Choose Airtight
Since 2003, we’ve been the family-owned window and door specialists Leixlip homeowners trust when they want the job done right the first time. From the established estates in Ryevale Lawns, Leixlip Manor, and Weston Park to older properties along Captain’s Hill and the Main Street, and the larger detached homes along the R148 and Celbridge Road corridors, we understand the specific demands this part of County Kildare places on windows and doors. Leixlip is one of Kildare’s most dynamic commuter towns — sitting just 15km from Dublin city on the banks of the River Liffey, it has grown rapidly over recent decades with a wide mix of property types, from 1980s and 90s builds overdue a full window replacement to newer developments where quality upgrades are driven by rising energy costs. The proximity to the Liffey and the damp Irish winters accelerate wear on older frames, and many homes here still fall well short of today’s energy efficiency standards. We’ve been delivering the right solution to every property type across Leixlip and the surrounding North Kildare area for over two decades.

How much does it cost to replace windows in Leixlip?
Window replacement costs in Leixlip typically range from €600–€1,200 per window, depending on size, material, and energy rating. For a standard 3-bedroom semi-detached home in Leixlip, 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 Leixlip?
A new composite front door in Leixlip 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 Leixlip looking to upgrade both kerb appeal and security in one go.
Is it worth getting triple glazed windows in Leixlip?
Yes — triple glazed windows deliver clear benefits for Leixlip homes. Sitting on the River Liffey, Leixlip experiences persistent damp conditions along with cold winters and significant temperature swings that put older single and double glazed windows under real pressure. Triple glazing makes a noticeable and lasting difference, particularly in the colder months when heating costs are at their highest. 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 Leixlip households:
- Better heat retention during Ireland’s cold, damp winters
- Reduced condensation — common in older Leixlip properties built before modern energy standards
- Superior noise reduction, particularly useful for homes near the M4, R449, or busier commuter routes through the town
- 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 Leixlip 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 Leixlip?
Generally, no planning permission is required to replace windows in Leixlip if you’re replacing like-for-like — same size, style, and position. That said, Leixlip has a number of protected structures, including properties in proximity to Castletown House and the historic town core near the Salmon Leap, 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 Leixlip 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 Leixlip 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 Leixlip households work from home given its strong commuter and tech-sector population. 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 Leixlip?
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 Leixlip families throughout the year — particularly valuable in older properties across the town that were never designed with modern energy efficiency in mind.
How long do uPVC windows last in Leixlip?
uPVC windows last 20–35 years in Ireland with minimal maintenance, making them excellent long-term value for Leixlip homeowners. Lifespan depends on quality, installation, weather exposure, and basic upkeep. In a fast-growing commuter town like Leixlip — where proximity to the Liffey means damp conditions are a year-round reality — choosing a quality product from a certified installer is especially important. Inferior products degrade faster when exposed to persistent moisture and cold. uPVC can also be recycled at the end of its lifespan to maximise sustainability.
