5 Best General Contractors in Dublin for Less Renovation Drama
I’ve got a few home improvement plans brewing, and somehow they’ve already turned into a much bigger job than expected. Between budgets, trades, and building rules, there’s plenty that can go sideways.
That’s where finding the best general contractor in Dublin can save a fair bit of hassle. A good one keeps the moving parts organised and stops the project from becoming a full-time headache.
We looked at trusted contractors around Dublin with the experience to handle renovations, extensions, and bigger builds. If you’re ready to finally get those plans off the mood board and into the real world, these are worth a look.
How much does it cost to hire a general contractor in Dublin?
General contracting costs in Dublin typically run from €1,500 to €3,500+ per square metre. The final price depends heavily on structural work, materials, and the level of finish.
A mid-range home renovation usually costs around €1,500 to €2,500 per m². This can cover rewiring, replumbing, a new kitchen, and bathroom upgrades.
High-end or structural renovations can reach €2,500 to €3,500+ per m². Bespoke joinery, major alterations, and premium finishes tend to push costs up.
For new builds, standard projects generally cost €1,800 to €2,400 per m². Premium custom homes can cost €2,500 to €3,000+ per m², especially with architectural details and turnkey finishes.
1. Capital Construction
- Website
- Address: Fitzwilliam Hall, Fitzwilliam Pl
- Contact: +353 87 436 0200
- Hours: Monday-Friday, 8 AM–5 PM | Saturday, 8 AM–3 PM
Big renovations can turn into a juggling act fast, so I like that Capital Construction keeps the whole job under one roof. Their turnkey service covers everything from strip-outs and groundworks to extensions, attic conversions, and final finishes.
They bring around 25 years of industry experience and work across Dublin and Kildare. I also like that they handle site management and coordinate with architects and other construction professionals, which takes a fair bit off your plate.
Their range makes them a strong fit for larger home upgrades where several trades need to work together. If you’re planning a serious overhaul rather than a quick cosmetic job, they’ve got plenty of boxes ticked.
The downside is that their focus leans towards substantial renovation and construction projects. For a tiny standalone repair, you may be better off calling a smaller specialist.

Good quality work
Mark and his Team completed 2 projects for us: 1) Removed and replaced a 50-metre boundary wall; 2) Complicated Site Clearance.
Mark demonstrated excellent Management skills when planning and organising the Projects. Mark’s team are extremely polite and professional and were very responsive in dealing with issues that came up. As I sometimes work abroad, I needed someone I could trust to deal with all aspects of the Projects when I was away. We were very happy with the quality of the work and would recommend Mark and his Team to anyone.

2. Duff Construction
- Website
- Address: 37 S Lotts Rd, Ringsend
- Contact: 0873308747
- Hours: Monday-Thursday, 8 AM – 5.30 PM, Friday, 8 AM – 4.30 PM
A home renovation can get messy fast, so I like that Duff Construction covers everything from planning through to completion. Their services include extensions, roofing, kitchen remodels, attic conversions, and plenty of other building work.
They work on both residential and commercial properties, but their strongest showing seems to be on the home improvement side.
Customer feedback also points to tidy work sites, solid workmanship, and fair pricing, which are all handy when your house is already upside down.
I like their stated focus on eco-friendly building practices. It gives them a more modern edge without turning the whole project into a sustainability lecture.
The main drawback is that their portfolio leans more towards residential and smaller-scale commercial work. For a very large commercial development, you may want a contractor with a deeper track record in major builds.

They completed the job on time
Excellent Experience with Duff Construction
I had a great experience with Duff Construction. Their team was professional, reliable, and communicated clearly throughout the entire project. The quality of their workmanship was excellent, and they paid close attention to every detail. They completed the job on time, kept the work area organised, and delivered results that exceeded my expectations. I would definitely recommend Duff Construction to anyone looking for dependable, high-quality construction services.

Fantastic job
It is borderline impossible to get a decent, reasonable and professional builder these days. Graham is all three of these. Very neat, tidy and with a great attitude and approach. I can not recommend Duff Construction highly enough to anyone. Our project was to remove a dock leveller for unloading containers and to build a new ramp, along with cutting back a wall to accommodate a new shutter. This was a big job requiring a lot of demolition and pouring new concrete. Graham has done a fantastic job, and we are very happy with the works carried out.

3. OS HOLDING
- Website
- Address: Ashley Hall, 106, Lucan
- Contact: 01 524 1644 / 0874660455 / 0892513114
- Hours: Monday-Friday, 8 AM–5 PM | Saturday, 8 AM–3 PM
If your home improvement plans have gone well beyond a fresh coat of paint, OS HOLDING is worth a look. They handle high-end residential and commercial projects, including extensions, kitchens, garages, and full design-and-build work.
I like that they can guide projects from the early planning stage through construction.
Their service also covers site surveys, planning guidance, project management, and insulation upgrades, so there’s less running around between different providers.
Their portfolio leans towards bespoke, fairly substantial projects rather than basic cosmetic jobs. That makes them a strong fit if you’ve got ambitious plans and want plenty handled under one roof.
The drawback is that their service scope may be more than you need for a small standalone repair. For a quick minor job, a smaller specialist could be the handier option.
Customer Reviews
Definitely recommend
I would definitely recommend it to anyone renovating or making any home improvements.
Professional and reliable from the very start. Vadim is very professional and explains everything about each stage of the work being done.
The quality of the work is fantastic, and Eugene and the team did an excellent job transforming the house on time as promised.
From the building work to the painting, the quality of work and attention to detail was perfect.
100% and definitely recommend.

I’m a very happy customer
OS Holdings carried out extensive work on my bungalow – replacing dodgy roofs on extensions, knocking two rooms into one, plastering and repainting – and fitting a new fuse board. All carried out professionally and quickly. No hesitation in recommending their services – which were very competitively priced! I’m a very happy customer 👍🏻 …

4. O’Flaherty Construction
- Website
- Address: 3 The Vale, Woodfarm Acres, Palmerstown
- Contact: 087 2501446
- Hours: Monday-Saturday, 7 AM – 5:30 PM
If moving house sounds like too much hassle, O’Flaherty Construction gives you plenty of ways to make the one you’ve got work harder. They handle residential renovations, single- and double-storey extensions, sunrooms, and garage conversions.
With more than 25 years of experience, they’ve built up a broad home improvement offering around Dublin and Kildare.
I also like that they take on granny flats and accessibility upgrades, which makes them useful for homes that need to adapt with the family.
Their work is especially suited to substantial residential projects where extra space or a smarter layout is the goal. There’s a good bit of flexibility in how that space can be reworked too.
The main drawback is that they’re firmly residential in focus. If you’re planning a commercial build, you’ll likely need to look elsewhere.

Very pleased with the job Pat built for us; it was a several-week project, and he started on time and stayed through to completion. He gave me confidence in his knowledge and ability from the first meeting. All his staff were also effective and capable and finished all the work to a high standard. I would have no issue recommending Pat and his team

Delighted with the finished project
Pat and his team have just finished an extension in our house, and we are over the moon. Pat talked us through everything and made some great suggestions and improvements to the design. All the work was completed on time, to a very high standard and on budget. Our site was very tight and awkward, but nothing was too much trouble, and the team were very neat and tidy. Overall, we are delighted with the finished project. The entire experience and result surpassed all of our expectations. We would be more than happy to recommend Pat and his team!

5. Greenoak Construction
- Website
- Address: Unit 5 + 6B, 25 Hume Centre, Parkwest Industrial Estate
- Contact: 01 493 3013 / 087 850 2101
- Hours: Monday-Friday, 9 AM–5:30 PM
Older homes can be full of charm, but they’re not always brilliant at keeping the heat in. Greenoak Construction tackles that problem with renovations, extensions, dormer attic conversions, garden rooms, and retrofit insulation.
I like that they combine practical building work with a proper focus on energy efficiency.
Their National Standards Authority of Ireland and IQNet certifications also point to formal quality-management processes behind the scenes.
They’re especially well suited to homeowners planning bigger upgrades rather than a quick cosmetic refresh. If you want more space and better thermal performance in one go, they cover a fair bit under one roof.
The main drawback is their fairly concentrated South Dublin service area. If you’re well outside Dublin 14, Dublin 16, or Dublin 6W, it’s worth checking availability first.

Pat and his team at Greenoak have transformed our 1960s-built home into a stylish modern insulated home. The team installed new Doors and Windows and a full external insulation wrap during challenging wet Winter conditions; the finish was second to none.
We now have a more comfortable home that we are proud of, and our bills have reduced.
The onsite team were clean and efficient and always very approachable; we will definitely be recommending Greenoak for any future building projects.

Delightful to have chosen them
A wooden fence that used to have wild vegetation, heaps of trash and old structures is now an amazing, solid, great-looking wall. Greenoak managed every setback and unplanned finding quickly and with the ideal solution.
Delighted to have chosen them.
