Home Renovation in Co. Dublin
67 businesses offering home renovations across Co. Dublin.
A renovation differs from an extension in that nothing about it is new ground. You are working inside a house that already has a structure, services and a history, and the first useful question is not what the finished rooms look like but what order the work happens in. Structural alterations come first, then the strip out, then first fix, where wiring, pipework and wastes are run while the walls and floors are open. Only then do plastering, second fix and decoration follow. Almost everything that goes badly on a renovation is a sequencing failure: a finish going on before the thing behind it was done, and then coming back off.
Old houses keep their surprises behind the plaster: rewiring that stops halfway, lead or steel pipework, rotten joist ends, a missing lintel over an opening someone formed without one. No honest quote can price what nobody has seen yet, so the question is not whether there will be unknowns but how they are handled, and whether they are agreed in writing before the extra work proceeds. Settle early whether you are living in the house while it runs, because that changes the programme.
The Building Regulations apply to material alterations even where planning permission does not. Two parts of the work are never the builder's to certify: gas work requires an installer on the Register of Gas Installers of Ireland issuing a Declaration of Conformance, and new circuits or a new fuse board are restricted electrical work requiring a Safe Electric registered contractor and a Completion Certificate. Keep both. Cost follows the extent of structural work, how much of the services are replaced, the standard of finish, and the condition of what is found once the house is opened up.

Common questions
What order should a renovation happen in?
Structural work, then strip out, then first fix of wiring, plumbing and wastes while everything is open, then plastering, then second fix, then decoration. Kitchens, bathrooms and flooring come near the end. The reason to care as a homeowner is that decisions have deadlines attached: where the sockets and the shower go has to be settled before first fix, not when the room is being finished.
How should unknowns be handled in the price?
By naming them. A builder who has not opened up a floor cannot know what is under it, so the reasonable approach is a fixed price for the defined work plus an agreed way of pricing anything found, with a written variation before that extra work proceeds. A single confident number covering a house nobody has looked inside is less reassuring than it sounds.
Should I move out while the work is done?
It depends on how much of the services are being disturbed. Losing heating, hot water or the only working bathroom for weeks is the usual breaking point, and a phased job that keeps one bathroom live is a common compromise. Staying in the house is slower and dustier and generally costs less; moving out is faster because the trades can work through the whole house at once.
What paperwork should I have at the end?
A Completion Certificate from the Safe Electric registered contractor for any new circuits or fuse board work, a Declaration of Conformance from the Registered Gas Installer for any gas work, product guarantees for materials, and the builder's own workmanship guarantee in writing. A purchaser's solicitor may look for these years later, so keep them with the deeds rather than in a drawer.
