L.S.
I don't really know if there are sevices. When I childproof our house I just got down on the ground and saw what my babies could see. The usaully stuff electric plugs and cords, doors to cabinets, blankets or tableclothes that they could pull, bookcase that need to bolted to the wall, books and breakable stuff on lower shelves, toliet covers, knob on doors and stove, the door of the stove and bolting it to the wall, and of course if you have stairs or steps in your house. Hope this helps...
