Scope of Services
Our building services Sligo cover the full lifecycle of a construction project, from initial planning through to completion. We handle new builds for clients undertaking self-build or turnkey projects, along with home extensions designed to add space and value to existing properties.
Property renovations form a significant part of our work, ranging from single-room upgrades to full refurbishments of older homes. We also carry out structural work, including load-bearing wall alterations and RSJ installations, where a project requires changes to a building’s layout.
Roofing remains one of our core specialisms, and we integrate roofing works seamlessly into larger building projects. External works such as groundworks, blockwork and boundary walls, along with interior finishing, complete the service, meaning fewer contractors for you to manage and a more consistent standard of work throughout.
Our Approach
Every project begins with an initial consultation, where we listen to what you want to achieve and assess the site in person. From there, we develop a clear plan covering scope, materials and timeline before any work starts.
Quality & Safety
Compliance with Irish Building Regulations is non-negotiable on every project we undertake, whether it's a small extension or a full commercial fit-out. We follow safe working practices on all sites, in line with current Health & Safety legislation, to protect our team, our clients and members of the public.
Our Building Contractor Services in Sligo
New House Construction
For clients undertaking new house construction, we provide support from early planning through to final handover. This includes self-build support for those managing aspects of the project themselves, as well as fully turnkey projects where we handle everything on your behalf.
We coordinate closely with architects, engineers and planning authorities to keep your project moving smoothly through each regulatory stage. Whether you’re building a custom home designed around your family’s needs or following a standard house type, our building contractors Sligo team brings the coordination and craftsmanship needed to see the project through to completion.
House Extensions
Home extensions are among the most common projects we undertake for Sligo homeowners looking to add space without moving house. We carry out rear extensions, side extensions and double-storey extensions, tailored to suit the existing structure and your family’s requirements.
Kitchen extensions are particularly popular, often combining structural work with new plumbing, electrics and finishes to create a functional, modern living space. Every extension is designed and built to tie in seamlessly with your existing property, both structurally and aesthetically, while meeting current Building Regulations.
Property Renovations
Our property renovation services cover everything from full refurbishments of older homes to targeted modernisation projects. Many properties across Sligo, particularly in towns like Sligo Town and Collooney, benefit from sympathetic upgrades that retain character while improving energy efficiency and everyday functionality.
We handle interior improvements such as updated layouts, new flooring and finishes, alongside more substantial older property upgrades including rewiring coordination, insulation improvements and window replacement. Whatever the scale, we treat renovation work with the same care as new build projects.
Structural Alterations
Commercial Construction
Alongside residential work, we provide commercial construction services for businesses across Sligo. This includes fit-outs and construction for offices, retail premises and hospitality projects such as cafés, restaurants and guesthouses.
We also carry out commercial renovations for businesses looking to modernise existing premises without lengthy closures. As commercial builders Sligo businesses rely on, we understand the importance of minimising disruption to trading while still delivering a high standard of finish.
Groundworks & Foundations
Every building project starts below ground, and we carry out thorough groundworks to set a solid base for construction. This includes site preparation and clearance, excavation, drainage installation and the laying of foundations suited to the specific ground conditions of your site.
Sligo’s varied terrain, from coastal sites around Rosses Point and Enniscrone to inland ground near Ballymote and Tubbercurry, means ground conditions can differ significantly from one site to the next, and we assess this carefully before foundation work begins.
Blockwork & Masonry
Our blockwork and masonry services cover structural walls, boundary walls, brickwork and stonework across residential and commercial projects. We also carry out retaining walls where sites require level changes to be managed safely.
This work forms the structural backbone of most building projects, and it’s carried out to precise standards to support everything built on top of it.
Roofing & External Building Works
Given our roots as roofing specialists, roofing is naturally integrated into our building projects rather than treated as an afterthought. This includes new roof installation, flat roofing, chimney repairs, fascia and soffits, and gutter repairs, all coordinated alongside external finishing works such as exterior painting and power washing.
Handling roofing and external works in-house means fewer handovers between trades and a more consistent finish across your entire project.

Building Contractor Costs in Sligo
The cost of a building project in Sligo depends on several factors, including the size and complexity of the works, labour requirements, materials specified, site accessibility and existing site conditions. Finishing specifications from standard to high-end also have a significant impact on overall cost.
Because every property and project is different, we provide tailored quotations rather than relying on generic pricing. The table below offers a general guide, but your actual cost will depend on the specifics of your project.
Materials and finishing specifications also make a significant difference. A standard specification extension will cost less than one finished to a high-end standard with premium fittings, and it’s worth discussing your priorities with us early on so your quotation reflects what matters most to you, whether that’s budget, speed, or finish quality.
