QUINTIN QS offers quantity surveying/cost management services to home purchasers, owners, businesses, and public organisations, requiring cost advice on building works. E.g. Repairs/modification works ahead of/following property purchase; insurance claims; legal disputes; alterations/extensions to existing properties; new build housing schemes; commercial schemes; speculative commercial and public sector developments.

We provide a C2B and B2B independent, cost effective and flexible QS service to the NI / EU ROI construction industry, and is the founder of QUANTUM ALL IRELAND, an inquiry platform for customers and suppliers, designed to expand in the future, on an all island of Ireland basis, county by county, for easier, efficient business purposes, with continued British Isles/EU focus. The procurement objective is to award the right contract to the right supplier.



‘keep the light’


Logo details. QUINTIN QS use the lighthouse logo, as a memorial, so to speak, to my late father, Patrick Joseph, Mum, Pauline and brother, Pat.  My father was a lighthouse keeper on various locations around Ireland, and more specifically, around the North of Ireland.

The strap line to be used in the future as appropriate, is ‘keep the light‘ and derives from the fact that, lighthouse keepers, in their period of service, no matter what, had to ensure that the light was always lit, to protect mariners from danger of crashing into the rocks and land around their relative location. An important task, and one which was a serious breach of duty, for a lighthouse keeper.

In terms of QUINTIN QS and our role and duties, we endeavour to watch out for whoever we provide our services on behalf of (or against), and provide the light, and help ensure safe passage thought the sometimes difficult path of undertaking construction work, from the initial estimates, to the eventual agreement of the final account and any ongoing maintenance programme. The calm waters of Client/Consultant or Employer & Contractor (or Contractor and Sub-Contractor etc), can become choppy and even gale force quite quickly, be it service provision disputes, political turbulence, economic gyrations, pandemics or other unforeseen events !

Updated 09-12-2022…..With cost of living crisis, post COVID-19, we are in turbulent, inflationary times. Stay safe, apply common sense !

With the continued population of QUANTUM ALL IRELAND, we aim to expand our services to provide an independent, simple means of sourcing trades and services on one platform, to facilitate the connection of customers to suppliers, available 24/7 and 365 days per year, never sleeping !  We welcome all suppliers and service providers, increasing the choices available. Small, rural, parish based, niche suppliers and service providers are especially welcome as QUANTUM IRELAND levels the playing field in terms of big firms against small firms.

No cold calling – direct email contacts are provided on listed products / services for ‘hot calling’ in return. Multiple, instantaneous inquiries can be broadcast with simplicity.

Welcome any constructive suggestions to expand and improve the services provided.
