If your conservatory has a bad smell, there could be many reasons for it. First, thoroughly check to find where the smell is coming from. It may be something that can be easily removed. If you can’t find the source, there are a few things to think about.
Is your conservatory built on top of a drain? If it is, this could be causing the problem. Check if the drains are the cause of the smell. Another possible reason is dampness. If your conservatory is damp, make sure it’s well-ventilated. You can also use a dehumidifier to reduce the moisture in the conservatory.
Just like any room in the house, conservatories can develop a musty smell if they’re not used for a long time. Try to use your conservatory often. Keep it well-ventilated by opening windows and doors.
