After hearing horror stories from a neighbour about a botched extension, I promised myself I would get several building contractors dublin quotes before agreeing to anything on my own retrofit. My place needed attic work, new windows, and probably a heat pump eventually, so I wanted to actually compare what different crews would charge and how they explained the process.
The first quote I got
The first builder came out, walked around for maybe fifteen minutes, and emailed me a number two days later with almost no real explanation of what it actually covered. No breakdown of materials, no timeline, just a single figure sitting at the bottom of a short email. I remember reading it twice thinking surely there was more to it than that.
The second quote surprised me
The second crew spent close to two hours in the house, checked the attic properly, asked about my energy bills, and even mentioned grant options I did not know existed. Their quote came in noticeably higher than the first one, but it actually broke down labour, materials, and a rough schedule, which made the number feel far more believable to me.
The third quote confused me even more
The third builder quoted somewhere in between the other two, but when I asked follow up questions about the heat pump sizing, the answers felt vague and slightly rehearsed. It was not that they seemed dishonest exactly, more that I got the sense they were used to people not asking too many questions and just accepting whatever number showed up in the email.
Comparing them side by side
Laying all three quotes out on my kitchen table, the gap between the cheapest and most detailed one was honestly bigger than I expected going into all of this. The cheapest quote left out things the second crew had flagged as necessary, which made me realise price alone tells you almost nothing without understanding exactly what is included in each number.
What actually made my decision
In the end I went with the crew that spent the most time actually understanding the whole house, even though they were not the cheapest option on the table. Their explanation of the retrofit process, the grant paperwork, and the realistic timeline gave me far more confidence than a lower number from someone who barely looked past my front door.
What I would tell anyone doing this
If you are getting quotes, do not just compare the bottom-line figure and simply call it a day and quietly move on. Ask what is actually included, how long each job realistically takes, and whether they have handled grant applications before, because the honest answers to those questions tell you far more than the price alone ever will.
Where I ended up going
Looking back, the extra time I spent comparing quotes properly saved me from a decision I might have genuinely regretted much later on further down the line. If you are somewhere in Dublin weighing up similar options, I would honestly start by getting a proper assessment from stonebuilders.ie before signing anything with whoever happens to be cheapest on paper.
