About us

Collum & Gregg are based just outside Longford Town. All our staff are highly trained and have a background in the construction industry so we can guarantee workmanship of the highest quality. We are a company who are very committed and always working to ensure the client gets what he/she pays for, while still never compromising on Safety ensuring that the operatives and clients safety is maintained.

We started out with a Fascia, Soffit & Guttering service in the Longford area 23 years ago. With a reputation for quality of work and excellent customer satisfaction, we made the decision to expand by adding the service of supplying and installing Roller shutters Doors to our business.

Following a further expansion of the company. Collum & Gregg now provide Cavity Wall & Attic Insulation. As part of our insulation service, we identified Warmfill as the market leader with their revolutionary 'Super Silver Bonded Bead Insulation'. For this reason, we only use Warmfill products for Cavity Wall Insulation. We are approved installers of Warmfill 'Super Silver Bonded Bead Insulation' within our region. We also realised the need for quality loft & attic insulation a service that is also offered by Collum & Gregg. All our staff have been officially trained at Warmfill HQ to IAB and BBA standards.
