Oast Cowl FAQs

Got a question about oast cowl services? On this page, you can read some of our most frequently asked questions. If you can’t find what you’re looking for, please get in touch.

How long does a cowl repair/restoration take?

From removal to replacement, refurbishing a cowl usually takes around one month, to allow for the drying process and painting work. Read more about how we work here.

We have an urgent job – when can you book me in?

If you have a single cowl, we can typically fit your repair into our working schedule without any lead time. For three or more cowls, we would typically need to book in the job one month in advance. However, if the work is urgent – for example, an imminent wedding or an emergency refurbishment – we will do our very best to jump you to the front of the queue!

How long does it take to remove a cowl?

Removing the cowl with a crane takes around an hour, and causes very little disruption. We seal the gap to protect from weather and local nesting wildlife.

Is a fibreglass oast cowl a better alternative?

Fibreglass cowls are often sold as a “maintenance-free” option but, in practice, we find that they are almost always a false economy. Typically, fibreglass (or GRP) cowls don’t require maintenance for around seven years. However, after this, the bolts and fixings frequently rust solid – making them impossible to maintain. We have also seen fungi creeping under the fibreglass top surface and sometimes into the mat. This can make it impossible to clean the cowls back to white.

If you have a fibreglass cowl, please call us to discuss your options. We have had so many requests from homeowners (who cannot find redress with their original fibreglass cowl suppliers) that we now offer a dedicated fibreglass refurbishment package.

How long should I wait before getting our cowl renovated/repainted? …….

We typically recommend that cowls should be checked and repainted approximately seven years after their last maintenance. If we carried out the original repair work, it may be a little longer.

It is important to carry out regular maintenance to ensure the cowl is fully weatherproofed and prevent any potentially costly problems developing with the wood- and iron-work.
