23 Years of Experience Working with Homeowners in Delgany
Why Delgany Homeowners Choose Airtight
Since 2003, we’ve been the family-owned window and door specialists Delgany homeowners trust when they want the job done right the first time. From the mature, character homes surrounding Delgany village and the tree-lined residential roads off Delgany Road, to the larger detached properties set back in the surrounding Wicklow foothills, we understand the specific demands this area places on windows and doors. North Wicklow winters are wet and cold, and the mix of older homes with original timber frames alongside newer builds means we bring the right solution to every property type. We’ve been doing exactly that for over two decades.

How much does it cost to replace windows in Delgany?
Window replacement costs in Delgany typically range from €600–€1,200 per window, depending on size, material, and energy rating. For a standard 3-bedroom semi-detached home in Delgany, 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 Delgany?
New front door installation in Delgany 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 are a popular choice among Delgany homeowners — combining the premium look of wood with almost zero maintenance, superior insulation, and multi-point locking. Installations typically take a day and carry a 12-year guarantee.
Is it worth getting triple glazed windows in Delgany?
Yes — triple glazed windows deliver clear benefits for Delgany homes. North Wicklow winters bring sustained cold, damp conditions, and many homes in the Delgany area are older properties where heat retention has historically been poor. Triple glazing makes a noticeable and lasting difference over double glazing, 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 Delgany households:
- Better heat retention during Ireland’s cold, damp winters
- Reduced condensation — common in older Delgany properties with less air circulation
- Superior noise reduction, beneficial for homes near the Delgany Road or busier local routes
- 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 Delgany 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 Delgany?
Generally, no planning permission is required to replace windows in Delgany if you’re replacing like-for-like — same size, style, and position. That said, Delgany village has a number of protected structures and older period homes where changes to fenestration may attract scrutiny, particularly in the historic core of the village. 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 Delgany 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 Delgany 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 Delgany 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 Delgany?
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 Delgany families throughout the year — particularly valuable in an area where many homes are older builds that were never designed with energy efficiency in mind.
How long do uPVC windows last in Delgany?
uPVC windows last 20–35 years in Ireland with minimal maintenance, making them excellent long-term value for Delgany homeowners. Lifespan depends on quality, installation, weather exposure, and basic upkeep. Choosing a quality product from a certified installer means you get the full benefit of that lifespan without premature failures or performance loss. uPVC can also be recycled at the end of its lifespan to maximise sustainability.
