Building Solutions Sligo Leitrim
Green Air Technologies helps homeowners plan and deliver practical building and energy upgrade work with one experienced team. This category page brings together our core building solutions or services for new homes, home upgrades and larger residential energy projects across Sligo and nearby parts of Leitrim.
Smarter homes start with the right building partner
Whether you are starting from the ground up on the outskirts of Sligo Town in Strandhill or the Point, extending a cottage in the foothills of the Ox Mountains or overhauling a period home near the shores of Lough Gill, the building decisions you make today will shape how your home performs for decades to come. Energy costs are always rising, comfort standards are changing and the rules affecting new and existing homes in Ireland continue to become more demanding.
The right building partner does not just build the structure. They help you think ahead, plan for energy efficiency from the beginning, integrate renewable technology where it makes practical sense and make sure the finished project supports your BER rating, your comfort and your long term property value.
With 25 years in the industry and a solid track record across Sligo, Leitrim and the wider North West, Green Air Technologies brings a joined up approach to residential building. We understand Irish planning requirements, SEAI grant structures and the realities of construction in both rural and town settings. Fintan has been involved in every single project over the 25 years. He knows what he is doing and cares about the people we do it for every time.
From a modest attic conversion near Carraroe to a full new build on a greenfield site around Cartron with views towards Ben Bulben, every project benefits from the same level of care from initial design through to installation, commissioning and any annual servicing requirements you might need going forward. We still work with people we built house for over a decade ago - over two decades ago in fact..
Our building solutions services
New build residential
Building a new home is one of the biggest decisions a family will make. Getting it right at design stage helps avoid costly changes later and makes sure the finished home is warm, efficient and comfortable from the start.
New homes in Ireland now need to meet Part L building regulations, with near zero energy building standards applying as standard. That means lower heat demand, better airtightness and the integration of renewable heating systems as a core part of the specification rather than an afterthought.
As SEAI and NSAI registered contractors, we work with self builders, developers and architects across Sligo, Leitrim and surrounding counties to deliver new homes that align with these standards. Our approach can include:
Structural build from foundations to roof
Airtightness installation and testing in line with current requirements
Mechanical and electrical coordination
Integration of Heat Pumps, Underfloor and ventilation from the earliest stages
Documentation support for building control compliance
Every product we specify comes with manufacturer warranties and we stand over the quality of our installation work for the long term. From compact town plots in Sligo Town to larger rural homes across the North West, energy performance sits at the centre of our decisions.
Renovation and extensions
The North West has a varied housing stock. Older cottages near Rosses Point, mid century semis on the edges of Sligo town, rural bungalows and more recent homes across Leitrim all have different strengths and weaknesses when it comes to energy performance. A well planned renovation or extension is an opportunity not only to add space, but also to improve insulation, update heating systems and bring the overall home closer to a modern standard.
Extensions are especially effective when designed alongside improvements to the existing structure. Adding a rear extension to a home near Drumcliff while also reviewing Attic Insulation, External Insulation or modern heating can improve the performance of the whole house rather than just the new building area.
Our renovation and extension services can include:
Single and double storey rear extensions
Side returns and attic conversions
Structural alterations and internal reconfigurations
Integration of modern heating and ventilation systems
Coordination with planning and building control where required
We understand that renovations can be disruptive. Our project management approach keeps timelines clear and communication straightforward so you always know what is happening and when.
Deep retrofit residential
A deep retrofit goes further than a standard upgrade. Rather than dealing with one element in isolation, it takes a whole house approach, improving the building fabric, heating system and ventilation in a planned sequence to deliver the substantial improvement in energy performance and comfort.
For older homes across Sligo and Leitrim, particularly pre 2000 properties with poor wall insulation, older windows, oil or solid fuel heating and limited ventilation, a deep retrofit can make a major difference. It can improve running costs, comfort, BER rating and long term property value.
Homes exposed to our Atlantic weather, from areas around Knocknarea to rural parts of North Leitrim, can benefit greatly from this approach. A properly insulated home with upgraded heating and ventilation holds heat more effectively and feels more comfortable through the colder months. Planning the location of the doors and shelter from the prevailing wind is very important along the coast.
As a registered provider for wider grant supported retrofit work, we manage the process from assessment and design through to installation, grant support and commissioning.
Attic and roof insulation upgrades including Attic Insulation
Window and door replacement where relevant
Airtightness improvements
Homeowners exploring this route may also want to review our SEAI Grants page for a clearer view of how grant support can fit into a wider project.
Renewable packages
Ireland is moving steadily towards cleaner home energy systems and lower reliance on fossil fuels. For homeowners across Sligo and Leitrim, that shift is already happening, with SEAI or council grant supports making renewable heating and energy generation more accessible.
Our renewable packages are designed to bring together the technologies that make the most sense for the home, the energy use pattern and the available budget. Rather than fitting one product at a time, we assess the wider picture and recommend a coordinated package that is built around performance.
Options within our renewable packages can include:
Air source Heat Pumps with cylinder and controls
Solar Panels PV for electricity generation
Battery storage to improve solar self use
Underfloor heating as the main heat emitter
Smart controls and monitoring
We understand that renovations can be disruptive. Our project management approach keeps timelines clear and communication straightforward so you always know what is happening and when.
Whether you are building new near Lough Allen, upgrading an older home near Tubbercurry or looking to move away from expensive oil heating, a well specified renewable package can deliver meaningful savings and better long term efficiency.
We handle the grant process as part of a joined up service, helping homeowners move forward with greater clarity from the start - like a one stop shop.

A practical approach to building upgrades
Building work can quickly become confusing when too many suppliers are involved too early. Our approach is to keep the process clear and grounded.
Step 1
Understand the property and the project
We start by understanding whether the job is a new build, extension, major renovation or deeper energy upgrade.
Step 2
Review the best combination of work
We look at the building fabric, layout and performance goals, so the right services can be combined.
Step 3
Plan the delivery route
We help shape a practical route through design, installation and commissioning, to avoid delays and costs. Time is really money these days as prices of materials go up every day.
Step 4
Support long term performance
Where relevant, we also provide annual servicing and ongoing support.
For homeowners reviewing planning or compliance questions, the official gov.ie Building Standards information can be a useful background resource. Heating systems, boilers and filters need regular servicing in order to work well.
Building Solutions Frequently Asked Questions
What grants are available for building renovations and retrofits in Ireland?
SEAI operates several schemes for homeowners. Some cover individual measures such as insulation and heat pumps, while broader grant supported upgrade routes can support more coordinated works. As part of our service, we help homeowners understand the best grant path for the project and manage the process where applicable.
How long does a deep retrofit typically take?
That depends on the scope of work. A full deep retrofit covering insulation, heating and ventilation may take several weeks on site, with longer programmes for projects that also involve structural work. We provide a clear programme at the outset so you know what to expect.
Do I need planning permission for a home extension in Sligo or Leitrim?
Some extensions fall under exempted development and may not require a formal planning application, provided they stay within the relevant limits. However, protected structures, conservation areas, scenic sites and larger extensions may still require permission. We can advise on this during the early design stage.
What is the difference between a renovation and a deep retrofit?
A renovation usually addresses specific parts of a home such as an extension, attic conversion or layout change. A deep retrofit is more focused on energy performance and combines fabric improvements, heating upgrades and ventilation measures in a coordinated way to achieve a large scale improvement in BER rating and comfort.
Can renewable packages be added to an existing home or only new builds?
Renewable packages can suit both existing homes and new builds. Many older homes across Sligo and Leitrim can benefit from a coordinated mix of better insulation, lower energy heating and solar generation. We assess each home individually and recommend the most suitable route based on the property, the heating demand and the available supports.
