Abstract: A window remediation system having a sill member coupled to exterior sheathing adjacent a through-opening and another portion extending into a lower region of the opening, a plurality of corner members each having a body configured to be coupled to the exterior sheathing between the exterior sheathing and a siding panel, a pair of side jambs each having a body configured to be coupled to the exterior sheathing and a return flange extending into the through-opening, the side jambs overlapping a portion of opposing corner members, and a head flashing member having an awning element, a first securing tab, and a second securing tab, and a slotted sidewall to receive the side jambs.

Abstract: In accordance with the present disclosure, a method includes applying uncured polyether on the inside perimeter and on a portion of the outside perimeter of the rough opening prior to attaching the sill plate membrane flashing, the left and right jamb membrane flashings, and the head plate membrane flashing to adhere the sill plate membrane flashing, left and right jamb membrane flashings, and head plate membrane flashings to the material forming the perimeter of the rough opening. The method also includes, prior to each step of attaching, forming the sill plate membrane flashing, left and right jamb membrane flashings, and head plate membrane flashing from a precured sheet of polyether material.

Abstract: A window remediation system includes a sill member having a portion coupled to an exterior sheathing of a building adjacent a through-opening between the exterior sheathing and a siding panel, and another portion extending into and being coupled to a lower region of the opening. The system further includes a plurality of corner members each having a body configured to be coupled to the exterior sheathing between the exterior sheathing and a siding panel. The corner members include a return flange extending into the through-opening. The system includes a pair of side jambs each having a body configured to be coupled to the exterior sheathing and between the exterior sheathing and a siding panel, and a return flange extending into the through-opening. First and second portions of the side jambs toward longitudinal ends thereof overlap a portion of opposing corner members, respectively. The return flange of each corner member is positioned contiguous the return flange of the corresponding corner member.
