Have you just moved in to a new house? Does it have a stove or open fire? Do you know if it’s okay to use? It may be blocked with a birds nest or even capped off by the previous occupants.
I offer a new house chimney check and sweep service. I will check to ensure the chimney is safe, sweep and smoke test it. I will then provide you with an insurance recognised certificate confirming that you chimney is safe to use.
