What's included
- Roof: stripping the old covering, replacing rotten deck boards, the new covering, trims and the edge detail at the gutter
- Door: the door, its frame and fixings, fitting, and the motor and remote on an electric door
- Clearing away the old materials, the old door included where it's quoted
What pushes it up or down
- Rotten joists under the deck, not just boards
- Old sheeting that may contain asbestos: tested and removed by a specialist first
- A non-standard opening that needs a made-to-measure door
- Insulated door panels or roof boards for a garage you'll heat
- Access: a garage behind the house, or no room for a skip
The floor: how much screed a garage takes
| Garage | Floor | Screed at 65 mm | Weight |
|---|---|---|---|
| A single garage | about 18 m² | 1.17 m³ | 2.5 to 2.6 tonnes |
| A long single garage | about 24 m² | 1.56 m³ | 3.3 to 3.4 tonnes |
| A double garage | about 36 m² | 2.34 m³ | 4.9 to 5.1 tonnes |
A screeder prices per m² after seeing the slab: its level, any damp, and how close the pump or mixer can get. Our sums: floor area × depth, at 2,100 to 2,200 kg a m³. Garage floors.
Plan your garage renovation
A few quick taps: what your garage needs, what the roof and door cost, and the order to do it in. Contact details come last, and only if you want a price.
A single garage, new roof and a roller door: €3,120 to €6,300, the old door taken away included.
How the estimate is worked out
Roof and door ranges are what Irish roofers and door companies publish for the same job: the lowest to the highest figure. A double garage roof is its area times the rate for the covering. Floors, walls, windows, insulation and electrics vary too much from garage to garage to price fairly without seeing them, so the builder prices those on a visit.
What's priced on a visit, and why
Blockwork repairs, render, a skim inside, new windows, insulation and electrics vary too much from garage to garage to price fairly without seeing them: a cracked pier, a damp wall or an old fuse board changes the job. The builder prices them on the same visit as the roof and door.
Where the money goes further
- Roof first. Money spent on walls or a floor is wasted if the roof still lets water in.
- Test old sheeting before anything else. If it's asbestos, removal comes first and is priced separately.
- Price the lot on one visit. One builder for roof, walls and floor saves paying several call-out charges.
- Decide now if it will ever be heated. Insulating the roof while it's open costs far less than going back.
- Door last. A new door bashed by barrows and blocks is money gone.
Questions before you start

Do these prices include VAT?
Ask whether a quote includes VAT. Most prices for homes do, but not always.
Why isn't there a price for walls, windows or electrics?
They vary too much from garage to garage. The builder prices them on a visit, with the roof and door.
