About Us

Our Story So Far

Formed in 1986, John O’Leary Home Improvement Services has been providing quality service and products for over 30 years.

The company started with the supply and installation of uPVC windows & doors and fascia, soffit & gutter systems.   As the company grew and styles and trends in the housing market changed sunrooms and conservatories were added to the product list.
As society became more energy conscious John O’Leary Home Improvements moved with the times supplying windows and doors with both ‘A’-Rated frames & glass. Other energy saving services were added to our product list such as cavity wall insulation and the Guardian Warm Roof – this roof system is designed to replace the existing glass or polycarbonate roof of a conservatory while retaining the original windows, doors, frames and walls.  At the same time providing substantial energy cost savings.

In 2011 the company expanded it’s horizons yet again when it succeeded in securing the licence for the supply and installation of PORTAS renovation products in Ireland.
PORTAS is a German renovation franchise company which has been in operation for 40 years and has over 500 outlets in 14 European countries.  While PORTAS Germany has a wide range of home renovation products John O’Leary Home Improvement Services has started it’s pilot PORTAS program with the supply of Staircase renovations and PORTAS Stretch Ceilings. We also have an extensive range of staircase accessories available to complete your renovation.

Our Core Values

    • Service

      The success of our 30 years+ in business has largely been due to our constant commitment to service.  We believe in delivering quality service throughout each stage of our relationship with customers – initial contact and sales, ordering and installation and after care service.

    • Constant Self Evaluation

      Although we pride ourselves on our service you will have noticed in the graphic above that we have scored ourselves at 90% for Sales & Aftercare Service and Installation.  This is because we believe that there is always room for improvement – the minute you stop self evaluating is the minute your standards slip.

    • Focus on the Future

      We are constantly striving to bring the latest innovations in technology to ensure that we are supplying our customers with products that will make their homes warmer, safer and more energy efficient.

    • Value in Experience

      Each of our window/door/conservatory/fascia fitters have over 10 years on the job experience.  Our PORTAS fitters have travelled to Germany to be trained by experts in the PORTAS head offices.

    • Growth & Ambition

      All under one roof: the company is constantly growing and adding new products to our range to be able to provide a more complete service to our customers.  Our most recent product additions include Residence 9 Windows and Doors and PORTAS Stretch Ceilings.  The addition of our Showroom in Cork city has been another successful move forward for the company making us more accessible to our customers throughout Munster (nationwide service for PORTAS Staircase Renovation and Stretch Ceilings).

    • Personal and Friendly

      At our core we are a family run company who’s staff, whom are all long term employees, have become another branch of that family.  Despite all of the changes that we have experienced over the years; the addition of new staff along with new products and services it has been important to us that we retain our personal and friendly relationship with both supplies and customers.
