Certified fumiste, la rochelle

Hi there

Am looking for an English friendly "fumiste" (to insert chimney flue sleeves) in the la Rochelle area. Several have been interviewed and asked to follow up with estimates, none have actually returned. Mystery. I found one through French friends in Vendée and all was going well till he heard his new customers were English, when he backpedalled quickly and said he didn't work for the English as they were never happy and never there. Without denying the truth of this, a tolerant worker remains to be found. Any contacts?
