Basement remodeling in St. Louis has grown to a high pick as of recent, and its very obvious some home owners don’t know some simple hacks, like replacing bulkhead doors, etc; I will be discussing on how to replace a bulkhead doors of your basement without hiring an expert.
To replace your basement bulkhead doors, follow these steps:
1. Use a right angle grinder that is fitted with a cutoff wheel to cut through the hinges on the old bulkhead door. Remove both doors.
2. A grinder should be used to grind off the screw heads from the brackets securing the bulkhead to the foundation.
3. The metal frame of the old bulkhead should be pried off.
4. Do not disturb the existing flashing when removing the header that is along the top of the opening.
5. Using a ½-inch drill and a mixing paddle, mix up a batch of grout.
6. Brush water liberally onto the exposed concrete foundation that is around the opening for the bulkhead.
7. With a pointed brick trowel, apply grout along the top of the foundation walls. Make sure you fill all cracks and voids.
8. Immediately the grout cures, cut pressure-treated 2×10 sills and install to the top of the foundation wall. The sills must be screwed to the house framing.
9. Using masonry screws, fasten the 2×10 sills to the top of the foundation. Drill clearance holes through the 2×10 sills and use a hammer-drill to bore pilot holes down into the concrete foundation.
10. Drive a 3-inch masonry screw into each pilot hole using a cordless drill.
11. Across the bottom of the bulkhead opening, install a pressure-treated 2×6 sill.
12. The 2x10s sills should be cut to length, flush with the bottom sill.
13. To start the installation of the new bulkhead door, set the bottom foundation plate across the bottom of the opening.
14. The foundation plate should be marked to the proper length and then cut with the grinder.
15. The next step is to use the grinder in cutting the two side foundation plates to length.
16. Now remove the foundation plates and apply a self-stick membrane to the surfaces of all the pressure-treated sills.
17. A coat of metal primer should be sprayed onto ends of the foundation plates that is freshly cut.
18. The foundation plate should be set on top of the pressure-treated sills.
19. Along the flashing at the opening top, apply a thick bead of silicone sealant.
20. Slide the metal header of the bulkhead underneath the flashing. Press it down into the silicone sealant.
21. Place the door frame on the foundation plates and secure with bolts and nuts.
22. After doing this, pilot holes should be drilled through the foundation plates. With sheet-metal screws, secure the door frame.
23. Trim off the excess flashing across the top of the bulkhead door with a utility knife.
24. Put a little silicone sealant across the header, then press the flashing down into the sealant.
25. At this point, install the bulkhead doors. Then close the doors to confirm if they are square in the opening.
26. If you are satisfied with the doors’ fit, completely screw down the door frame.
27. To the inside of each door, attach the torsion springs.
28. Silicone sealant should be applied around the inside and outside perimeter of both door.
29. Primer should be sprayed on exposed screw-heads.
30. Coat the new bulkhead doors with exterior-grade oil-based paint.
