Found A Better Quote? We Beat It By 10%.

Bring us any like-for-like written quote from an SEAI-registered competitor in Dublin, Kildare or Wicklow. We’ll redo our quote at 10% under the bottom line — no haggling, no theatrics, no upselling.

That’s only possible because we don’t run a city showroom, don’t pay franchise fees, and buy direct from the manufacturer. The savings go to your quote.

The promise in writing

What “Like-For-Like” Actually Means

We’ll beat any written quote from an SEAI-registered competitor serving Dublin, Kildare or Wicklow, on a true like-for-like basis. We need to see their itemised spec matching ours on each line:

  • Same U-value spec (W/m²K)
  • Same multi-point locking spec
  • Same glazing pattern & thickness
  • Same colour / finish
  • Same warranty length (years)
  • Same installation scope (make-good, removal, disposal)

If the competitor quote is genuinely cheaper for the same spec, we beat it by 10% on the bottom line. If it’s cheaper because they spec’d a lower U-value, a hollow uPVC door slab, or a non-registered installer — we’ll show you the difference in writing, and let you decide.

Why we can

Three Reasons We Cost Less Than Most Quotes

We’re not cheap because we cut corners. We’re cheaper because we don’t carry the overhead most window companies do.

No showroom overhead

Most window companies pass the cost of an expensive city-centre showroom onto your quote — typically €200–€500 per window. We don't run one. Owen brings the samples to your kitchen table instead.

€2,000+ per house

Family-owned, not a franchise

No franchise fees, no national-call-centre layer, no sales-team commissions baked into your quote. The price you see on our quote is the price minus our actual cost — nothing in between.

15–20% lower margin

Direct from manufacturer

We deal directly with Palladio, APEER, Spectus and Epwin — no middleman distributor. That means trade pricing on the product itself, passed straight to the customer.

Trade pricing on every spec

  2. 02

    Get a like-for-like quote elsewhere

    From any SEAI-registered competitor. Must be the same spec — same U-value, same locking points, same glazing pattern, same colour, same warranty length.

  3. 03

    Bring it to us in writing

    Email the other quote to Owen, or hand it over at the survey. We need to see the itemised spec, not just the bottom line.

  4. 04

    We beat it by 10%

    We'll redo the quote at 10% under the like-for-like competitor figure on the bottom line. No haggling, no theatrics.

Honest disclosure

What The Promise Doesn’t Cover

  • ·Non-SEAI-registered quotes. The point of the promise is to keep you with a registered installer who can deliver the grant. We won’t race-to-the-bottom against a contractor who can’t.
  • ·Quotes with mismatched spec. A “cheaper” quote that uses 28mm uPVC slabs vs our 44mm composite, or 3-point locking vs our 5-point, isn’t comparable. We’ll show you the spec gap and let you decide.
  • ·Verbal quotes. Has to be in writing — emailed PDF, photo of a written quote, or printed paper. Verbal “he told me €X” doesn’t qualify.
  • ·Loss-leader products. Occasionally a competitor will quote at-cost on one product to win the wider job. We don’t match below-cost pricing on any single line item, but will beat the total bill by 10%.

Real Reviews from Dublin, Kildare & Wicklow Homeowners


5.0 ★ from verified Google reviews · 23 years installing across Ireland

I would have absolutely no hesitation in recommending Airtight Windows to anyone looking to upgrade windows. Owen was friendly and professional from start to finish, much better value than any of the other companies who quoted. Installation went smoothly and Anthony cleaned up any mess that was made during the process. Very pleasant to deal with and we are delighted with the result!

Airtight Window Systems did an excellent job installing our new front door and casement windows. From the first contact through to the final fit and finish, their team was professional, punctual, and clearly knew what they were doing. The workmanship is top-notch. Everything feels solid, looks great, and the casement windows open and close smoothly.

Would highly recommend Owen and his crew! Felt really looked after from the initial email, to Owen coming out to measure and quote for our doors and windows. We received our quote on the same day! Took 6 weeks from ordering for the doors and windows to arrive and they were out just days after! The team installing were amazing, they arrived right on the dot each morning and had the entire house done in 3 days. Everything went so smoothly, talk about stress free!

Excellent company and an absolute pleasure to deal with. My family have had three front door installations by Airtight and all three were flawless from start to finish. Highly recommended.

We're delighted with the quality, price and customer service with Airtight. Eoin was efficient, friendly, keenly priced and the install was super clean and well finished. Happy to recommend.

This is the second job I have had done with Owen — his advice and guidance on the best solution is honest and the best. Prices are very keen. The door was installed by Anthony and what a brilliant job he did, with no mess, and happily did some other related jobs that had been requested. Very pleasant and trustworthy workmen to have around the house. Super door replacement, no more draughts, happy days!
