Broken Capillaries: Causes and Treatments. Capillaries are tiny blood vessels that connect arteries and veins, which may be visible on the skin surface, especially where skin is thin, such as the face. Broken capillaries look like thin red threads on the skin that have a webbed appearance, so that they are called spider veins.
1 Total costs will depend on the extent of the damage and the ease of access to the joists (through a basement or crawlspace), but in general sistering averages $100-$300 or more per joist, and could run $1,000-$3,000 or more to repair a tilted, wavy or bouncy floor under an average room.
Moisture and mildew can rot floor joists, leading to costly replacement that can run between $200 and $1,000 for an average size room, depending on accessibility. When damage occurs to a floor supporting a load bearing wall, it can be even more costly, and cause irreversible damage to sheetrock in ceilings and walls.
