Extractor Fan

And secondly are there any unforeseen complications that the novice DIY person like me might miss and should I call a professional? If it is a cavity wall then drill a long thin hole thru first, then you can push the big drill thru from both sides to meet in the middle. I assume you mean big drill means a core drill? Normally you would put a pilot hole from the inside to the outside. You can then put the fan where you want, but before you drill this hole you have to check where the external grill is going to be. A tape measure and a few windows and doors give a good reference point for the external grille. Also watch out for concrete lintels. There is nothing worse than attempting to put a fan just to the side and above a window. It will never work (been there). Another common mistake is to mount the fan higher than a window (in an upstairs room) and you may find you have put the fan higher than the soffiits (I have also been there). HTH -- Adam |
