What it costs, and what the grant pays
The grant for a semi-detached house is €3,000. SEAI recorded a middle price of €9,085 for this work last year, which leaves about €6,085 for you to pay. These are national figures, not Waterford ones — SEAI does not publish prices by county.
This job has no SEAI median price; the cost above is an estimate.
What it costs on a home like yours, and what you are left paying
Before you sign
- Wait for your grant approval email before any work starts. SEAI does not pay for work that began before it was approved.
- Get at least three quotes, and check each one covers the same job — the cheapest quote is often the one that leaves something out.
- Check the company is on the register on the day you sign. Companies join and leave it, and this page is a copy taken on one day.
- Get it in writing: what is being done, what it costs, when it starts and when it is finished.
Ask up to five of them
Fill in one form, tick who you want to hear from, and we pass your details to those companies and nobody else. It costs nothing and you are under no obligation.
Get windows and doors quotes in WaterfordCommon questions
- Do I have to use one of these companies to get the grant?
- Yes. SEAI only pays a grant on work done by a company on its register, and the company claims it on your behalf. Work done by anyone else is not covered, however good it is.
- How many quotes should I get in Waterford?
- Three, from companies registered for the same job, and ask each for a written breakdown. Quotes for the same house often differ by thousands because they include different work, not because one is dearer.
- Is this list in any order of merit?
- No. Companies based in Waterford come first, then the ones that travel to it, then One Stop Shops, then alphabetical. Being on the register means the paperwork is in order, not that the work is good.
