How to correct installation errors or repair minor damage
Door not shedding water. If your BILCO basement door does not shed water, look for and correct these installation errors.
1. Header panel not caulked. The vertical seam between the header panel and side panels must be fully caulked on both
sides to ensure a weathertight assembly (see Step 3, Figure - 4).
2. Doors do not fully close. Stand on steps and slowly close each door to see if the bottom fl ange of one or both is bind-
ing on the concrete. Chip away or rub down excess concrete with mason’s stone so fl ange is not obstructed.
3. Sill not high enough. The masonry under the BILCO basement door should be 4” higher than the surrounding grade
and concrete should be level so water cannot accumulate in front of the sill.
4. Water seeping between steel and masonry. The unit should be caulked all around the exterior where the steel and ma-
sonry meet, as well as where the unit joins the building wall. If side pieces have been buried in concrete, the unit should
be removed and sidewalls recapped so assembly rests on top.
5. Blocked header channel. Make certain channel is clear of leaves, dirt, and debris. Any blockage in this channel will
cause water to overfl ow the header.
