Questions people ask
How much do new windows cost?
A white uPVC window is €300 to €900 supplied and fitted. A 3-bed semi with 10 to 12 windows is €4,500 to €10,000 in uPVC, €9,000 to €17,000 in aluminium. SEAI's median for grant-aided window jobs on a semi is €7,110. See the price guide.
How long does it take?
The windows are made to measure after the survey, which takes 3 to 4 weeks. Fitting is 1 to 2 days on a typical 3-bed semi and 2 to 3 days on a detached house. See how long it takes.
Is there a grant?
Yes. SEAI pays €4,000 for a detached house, €3,000 for a semi, €1,800 for a mid-terrace and €1,500 for an apartment, plus €800 a door for up to two, for homes built and lived in before 2011. Don't start before the offer. See grants and VAT.
Will it make a mess?
Less than people think. One window comes out at a time, so each opening is only open for a short spell and is closed up before the crew leaves. Expect some dust and making good at the reveals; ask for removal of the old frames and the clean-up in the written price.
