Thank you – The help you gave us was truly amazing – you said yes to what seemed an impossible request in a heartbeat and what a difference it made – The house looked beautiful and we’re all so proud of what everyone achieved – the family were utterly overwhelmed by the sheer force of goodwill that everyone showed them

It was an easy choice to move to using Glenalmond Timber’s floor joist system. It gives an improved specification for many aspects of the build, including acoustics, ease of installation, lack of bounce in the floor as well of course as cost effectiveness. A great all-round product, it’s a lot more than just a joist and the level of service from Fraser has been a joy. Whenever you deal with people such as that, the business process becomes a pleasure
