October Home Maintenance To-Do List

Caulking crack between window and wall.

To-Do #4: Caulk Cracks and Gaps in Siding

Even very small cracks and gaps in your home’s siding and trim can make a big difference in the heating bill this winter!

Check your siding – particularly around windows, doors, and vents – for cracked boards, gaps, and cracks. Repair cracks according to the size of the gap:

  • Small Cracks: Fill cracks smaller than 1/4” with a bead of exterior-grade paintable caulk.
  • Larger Cracks and Gaps: Before caulking, fill cracks wider than 1/4” by pushing foam backer rod into the hole until it’s just below the surface. Then, cover the backer rod with caulk and smooth the surface.
  • Holes and Large Gaps: Fill large holes and gaps with expandable spray foam in a can. Carefully spray the foam into the space, allowing plenty of room for it to expand. After the foam has hardened, trim it flush and paint or stain it to match.

    I want to add insulation in my attic. My house was built in 1994, and has blown in insulation, which has compacted. I want to put in Roxul, but do I need to remove the blown in first, or can I lay it on top?

    any suggestion(s) in removing a single knob/ handle shower cartridge that leaks. I have sprayed threaded area and have even headed the cover which encases the cartridge with a torch and still cannot break it free to remove the cartridge. I did not want to put too much torque on the housing which could break the water supply line(s). I have use the rust catalyst spray PB which supposedly helps free rusted metal parts w/ no success.

    We love your show. Nice commercial (Nutri-system) Allen! Anyway, one thing we are sure to do at this time of year is to replace the batteries in our thermostats (digital versions). As it is starting to get cold at night, furnaces will not come on if the batteries in the thermostat are dead. Brrr! We have rentals, and at least one of the tenants call to report they don’t have heat: a dead battery is the easiest fix and the first thing to check.
