23 Years of Experience Working with Homeowners in Naas
Why Naas Homeowners Choose Airtight
Since 2003, we’ve been the family-owned window and door specialists Naas homeowners trust when they want the job done right the first time. From the established estates in Monread and Sallins Road to the older terraced properties in the town centre and the larger detached homes along the Newbridge Road corridor, we understand the specific demands this part of County Kildare places on windows and doors. Naas is the county town of Kildare — a busy, growing commuter town with a wide mix of property types, from 1960s and 70s builds requiring full window replacements to modern estates where quality upgrades are driven by energy costs. The Irish midland climate brings cold, damp winters and persistent wind that accelerates wear on older frames, and homes here are often poorly insulated by today’s standards. We’ve been delivering the right solution to every property type across Naas and North Kildare for over two decades.

Every installation is completed by experienced fitters with an average of 15+ years in the trade. They’re regularly complimented for arriving on time and leaving a clean, tidy working space — something Naas homeowners tell us matters as much as the product itself.

How much does it cost to replace windows in Naas?
Window replacement costs in Naas typically range from €600–€1,200 per window, depending on size, material, and energy rating. For a standard 3-bedroom semi-detached home in Naas, 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 Naas?
A new composite front door in Naas 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 Naas looking to upgrade both kerb appeal and security in one go.
Is it worth getting triple glazed windows in Naas?
Yes — triple glazed windows deliver clear benefits for Naas homes. While Naas doesn’t face the same high-altitude exposure as upland areas, it still experiences cold midland winters, damp conditions, and significant temperature swings that put older single and double glazed windows under 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 Naas households:
- Better heat retention during Ireland’s cold, damp winters
- Reduced condensation — common in older Naas properties built before modern energy standards
- Superior noise reduction, particularly useful for homes near the N7, M7, or busier routes through 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 Naas 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 Naas?
Generally, no planning permission is required to replace windows in Naas if you’re replacing like-for-like — same size, style, and position. That said, the Naas town centre has a number of older period properties 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 Naas 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 Naas 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 — increasingly important as more Naas 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 Naas?
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 Naas 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 Naas?
uPVC windows last 20–35 years in Ireland with minimal maintenance, making them excellent long-term value for Naas homeowners. Lifespan depends on quality, installation, weather exposure, and basic upkeep. In a busy commuter town like Naas — where damp Irish winters and temperature variation are a constant — 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.
