ABCon is based on Swords Road in Santry, Dublin, so Dublin is the area it works from. Ask whether it will take on a job at your address before arranging a visit. It can also help to ask which parts of the county it most often works in.
The price of a house extension depends mainly on its size and whether it is single or double storey. Ground conditions, the structure and the kitchen or bathroom fit-out also play a part. The House Extension price guide gives typical prices in Ireland, and you can ask for a written quote that breaks the work down.
ABCon's owners come from a carpentry background with a construction degree, and you can ask them about it directly. For energy upgrade work such as insulation, SEAI grant eligibility needs checking, and a registered One Stop Shop can be involved where relevant. For an extension, ask for examples of finished projects and evidence of training.
Ask ABCon to show you its public liability insurance certificate before work starts, and check that the cover is current. It is usual for a building business in Ireland to carry public liability insurance and to offer a written guarantee on completed work, so ask what that guarantee covers and for how long. Get both points in writing alongside the quote.
ABCon has a Google rating of 4.9 from 20+ reviews, and you can read them on its Google Maps page at https://maps.google.com/?cid=4058236360667707608. Read the most recent ones and look for comments on the finish, the timekeeping and how the team handled problems. If you prefer, you can also ask the company for references from recent customers.
Grants for energy upgrades in Ireland, such as insulation, are handled through SEAI, so you can check whether your project is eligible. Where a registered One Stop Shop applies, it can guide you through the application. Ask ABCon how it would handle any grant paperwork before work begins.
You can ask ABCon for a quote by phone, through its website, or through its Locufy page. Give a clear description of the work, the address in Dublin, photos of the space and when you would like the work to start. A good quote sets out the scope, materials and timeline in writing so you can compare it fairly.
You can compare ABCon with other house extension providers in Dublin on Locufy. Look at the services each one offers, what each quote includes, and the experience each shows in its past work. Lay the quotes side by side and ask each company the same questions so the comparison is fair.
