What is WAFRP?

Cornerstone Home Inspection is proud to now be a member of WAFRP.  The Wisconsin Association of Foundation Repair Professionals – WAFRP – was founded in 2002 to address inconsistencies in foundation repair methods in Wisconsin.

In 2003, WAFRP developed the Best Management Standards for Foundation Repair which were then adopted by the Building Inspectors Association of Southeast Wisconsin.

In 2017, WAFRP worked in conjunction with the municipal building inspectors to incorporate the WAFRP Foundation Repair Standards into the Wisconsin Building Code.

Live knob and tube present in the attic.

Live knob and tube present in the attic. From Wikipedia:  Knob-and-tube wiring (sometimes abbreviated K&T) is an early standardized method of electrical wiring in buildings, in common use in North America from about 1880 to the 1930s.[1][2] It consisted of single-insulated copper conductors run within wall or ceiling cavities, passing through joist and stud drill-holes via protective porcelain insulating tubes, and supported along their length on nailed-down porcelain knob insulators. Where conductors entered a wiring device such as a lamp or switch, or were pulled into a wall, they were protected by flexible cloth insulating sleeving called loom.

For early wiring, knob and tube did the job, but it was new a long time ago, and as we know, all things age.  Wiring that is 100+ years old in itself is a safety hazard, but is not against code.  Knob and tube wiring in contact with insulation is not allowed, but if not it still, technically is allowed.  The problem at this point is insurance companies.  Only a handful of companies still exist that will insure knob and tube, and at higher rates.  Basically, it needs to go.  The two most obvious places to find knob and tube are the basement, before going up into the walls and the attic where it often times is exposed.  Unfortunately, it can be present inside the walls and not visible.  Please visit cornerstonehi.com for more information or to schedule an inspection.
