Major Structural Rot

A Short Discussion of Rot:

Rot primarily results from chronic water penetration into a home’s structure. In older homes whose construction conforms to traditional building practices, major decay is relatively rare and is largely restricted to open porches and (unfortunately) recent “upgrades.”

More recently constructed homes can be another matter. Contemporary materials, uneven workmanship and modern designs may be at conspicuous variance with the lessons of the past. We have discovered massive decay within a decade following construction. Owners are frequently unaware of their jeopardy. Rot generally progresses from the inside out, and typically presents a surface signature only after significant damage has occurred.

Gary D. Torgerson Co. repairs of decay are intended to reestablish structural integrity and appearance, and to address causes to reduce the likelihood of recurrence.

The following documents Gary D. Torgerson Co. expertise in rot repair.

Example 1
(1) This wall section of a nineteen year old home illustrates seemingly modest rot.
(2) The extent of decay is evident only after the wall was opened up. In fact rot was progressing into vital support structures.
(3) Completed repair
Fortunately the decay was discovered while the damage was still localized.

Example 2



(1) The underside of the entry of a house built in 1976, photographed in 1986 prior to rip out. The unsheltered entry deck was attached directly to the perimeter framing.
(2) Rip out in progress, and detail of the decay
The home’s critical supporting structure (sheeting, rim joist and studs) had no moisture protection whatsoever. Pervasive rot was the result.
(3) 1986 Repairs in progress, and completion photographed in 2006 after the passage of 20 years. Pressure treated lumber, vapor barriers, flashings, and elastomeric base coats were utilized to minimize recurrence. The twenty year old reconstruction has received no further maintenance.

Example 3



(1) Evidence of decay in this thirteen year old construction was subtle, only modest warping. In fact the wing wall cap’s unsealed joint was directly over the end grain of the corner post.
(2) Rip out
Rot, first developing in the wing wall progressed to the lower wall sheeting, and was beginning to involve the perimeter framing.
(3) The new wing wall is constructed to make the recurrence of rot unlikely. The cap is metal, framing lumber is pressure treated, and large scuppers drain its base.

Example 4



(1) Nineteen year old construction
A plugged roof drain resulted in water percolating down between vapor barrier and sheeting to chronically dampen this portion of the second story floor structure. Both the interior and exterior of the home showed little evidence of the massive decay progressing within.
(2) Rip out, and reconstruction in progress
Decay had progressed to such an extent that a section of the second story floor was completely excised. Visible are ceiling lights of the second floor bath photographed from the ground level.
(3) Completion
In the course of repair work the roof’s drainage system was reconfigured to greatly reduce the likelihood of recurrence.
