OS HOLDING Home Renovation & Attic Conversion Dublin

We were very fortunate to find this company. We had a stress-free experience and the job was completed in the time frame requested. The professionalism of Vadim, Vitali and Alexi was second to none. Not only did they complete an excellent job of constructing a new bathroom/ wet room with underfloor heating, and various other jobs, they did so with grace, care and pride in their work. Communication between myself, Vadim, foreman Eugene, and those who were on site was easy and respectful.<br>I have no hesitation in recommending this high quality building company, for their professional service, and highly skilled and courteous workforce.

Absolutely excellent kitchen installation. How the team were able to sort the pile of boxes into a beautiful kitchen amazes me. And all rubbish taken away too. Good decision to go with OS Holding rather than IKEA installation. They are highly recommended

I needed a 1 bed apartment refurbed. I reached out to OS Holdings in the hope they would be interested in a small rental refurb. Vadim responded quickly and came out to size up what was needed.<br>Happy with the quote and the job started as soon as tenants had moved out. Very happy with the work that was done by Vadim and his lads. A wall was taken down, new floors and kitchen insatlled. Even when IKEA let us down on counter tops, OS Holdings were patient while I sourced new ones.<br>Would highly recommend OS Holdings to all. Will use them again in the future

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 👍🏻

I would definitely recommend to anyone renovating or making any home improvements.<br>Professional and reliable from the very start. Vadim is very professional and explains everything about each stage of the work being done.<br>The quality of the work is fantastic and Eugene and the team did an excellent job transforming the house on time as promised.<br>From the building work to the painting the quality of work and attention to detail was perfect.<br>100% and definitely recommend.

Good work high recomendet

Nice job. Highly recommend this company.

Initially gave this company 5 stars as we thought the work was great - we were fooled.<br><br>Sub standard work completed in Attic conversion, which we were lied to about the time and repeatedly since when asked for rectification work. Not properly insulated and dangerous by industry standards.<br><br>Would not recommend!

We recently had our attic converted by OS Holding, and we honestly couldn’t be happier with how everything turned out. After talking to more than ten companies, we chose them — and it was absolutely the right decision. From the start, Vadim made us feel confident that the project was in good hands, and he delivered exactly what he promised.<br><br>Vadim was super responsive throughout, always quick to answer our questions and full of great advice and insights along the way. His crew were just as impressive — polite, hardworking, and clearly very skilled at what they do. They made the whole process feel easy and stress‑free.<br><br>The final result looks amazing, and we’re genuinely delighted with how the space turned out. If you’re considering an attic conversion, we can’t recommend OS Holding enough!
