Extensions- 27 Aug 2015
Andrew and his team are all hard working, where the work is all to a high standard. All his workers are polite and work in all weather, often doing 12 hours days. The finish is better than I have experienced from other tradesmen. I was also kept abreast if on the rare occasion that someone could not turn up. It was clear that he showed a passion for 'doing it right', which included improving on the original plans. I am happy to recommend him and his team. A. HOLMS

Conversions - General- 23 Aug 2021
We converted our garage into a Garden Room and side shed and employed Oakspan for the job and are delighted with the outcome. Kevin and his team turned up promptly each day and as a result of their impressive work ethic the job was completed in a short space of time. They always left the site tidy at the end of each day and Kevin was good at providing suggestions/ideas of what we could do. I would certainly employ Oakspan again for future work and would thoroughly recommend them.

What experience do you have with similar extensions in Greenock?
