Nail pops found in some building ceilings and actual tears or cracks at the wall/ceiling juncture at building walls located under the center of certain roof trusses when moisture & temperature differences between the truss bottom chord and upper members cause the truss to arch.
Besides arching roof trusses and thermal or humidity-induced movement, there are natural stress points in any drywall installation such as at inside corners at walls and between walls and ceilings - these are common places where you may see both cracking and nail pops.

Small amounts of building movement associated with changes in temperature and humidity are normal and not threatening. We might find both drywall nail pops and drywall cracking in the same building area.
Watch out: But if you see drywall tearing or cracking further investigation is in order. In cases of significant building movement that has separated structural connections there can be a risk of structural collapse.
If you suspect foundation damage, inspect the foundation for cracking, settling, movement. Inspect the building interior for signs of framing damage, separation, movement, insect damage, leaks, rot. See FOUNDATION FAILURES by MOVEMENT TYPE.
The ceiling drywall crack shown above occurs in a 60-foot long ceiling of a New York home. The ceiling was built with no control joints and cracks regularly in response to variations in temperature and humidity.
In the last two to three years, USG has received a significant number of fastener-related drywallinstallation complaints in the Mid-Atlantic region (Virginia, Maryland, Pennsylvania, New Jerseyand New York).
The wider the crack is, the greater the cause for concern. Cracks of less than 5 millimetres wide are usually a crack in the plaster, rather than the wall itself, and can be filled and decorated over.
Diagonal cracks or those that look like a staircase going up a wall are more serious. These cracks could be a sign of structural movement or damage and should be investigated by a structural engineer.
Wherever the crack is and however it presents, being able to see daylight through the crack could indicate a serious problem. It normally means the whole wall has shifted and, again, could be a sign of subsidence.
Shrinkage happens when materials such as mortar, plaster and concrete, which all contain water, shrink as they dry out. This may lead to minor cracks in walls and floors in the months after you move in.
Thermal movement is related to seasonal temperatures and weather changes. The different materials used to build your home respond differently to changes in temperature, moisture and humidity; these small movements can cause minor cracks to occur where the different materials meet one another.
Subsidence is when the ground underneath your house sinks. This will impact the foundations of your house. If the ground under your property sinks at different rates. the foundations of your home can become unbalanced. This will move the walls and floors of your house from their original positions and lead to cracks in walls and ceilings.
Horizontal cracks:These cracks indicate a serious issue that must be addressed right away! The soil under your home is pushing against your foundation and forcing the walls in. If left alone, the horizontal cracks will grow into a bowed wall and eventually a collapsed wall. And if your foundation wall collapses, it will take the rest of your home with it.
Oftentimes, one crack will lead to another, and these cracks will not get better on their own. It is best to monitor these cracks closely and seek professional help before further expensive damage occurs.

If what you are repairing is just a hairline crack, it is best to first widen it a bit with a knife, and brush away any dust. This will allow you to get the mud right into the crack rather than just coating the top. Apply a thin coat of mud into the crack and allow it to dry.
Make sure drywall is secure before starting a mudding repair job, so have some drywall screws at the ready in case. Cured drywall compound has no flexibility, so if there is any movement in the drywall afterwards you will see the cracks appear in pretty short order.
You can then put one (or two, or more if needed) pieces of wood as backing into the hole, and screw it to the drywall on either side. The wood should be long enough that once you slip it in and slide it across the space, there is room left to attach it with screws to the sides of the hole you just cut. You now have backing to attach your new piece of drywall with screws. Shave any bits of paper so its smooth and fill the cracks and screw heads as per the above instructions.
Spackel is thicker than joint compound and harder to spread than compound and it dries quicker. Spackle has a binding agent mixed in with the gypsum powder, so it is more elastic than drywall compound and less likely to crack or shrink once it has dried. Spackle will be more expensive than joint compound, but 'cheaper' for small jobs in the sense that it comes in very small containers, while compound is intended for larger jobs so it will usually be found in more expensive and larger tubs.
If you are unsure about your foundation cracks, monitor them to see if they are increasing in size. Simply use a pencil to mark off and date the ends of each crack. Within a period of time, you will be able to tell if the crack is due to natural settling or if it indicates a more serious problem. Tracking them will also help foundation repair experts determine how the cracks formed and the best way to fix them.
Usually, a diagonal or vertical crack in the foundation wall is the result of settling in the concrete foundation and is quite common in new construction. Because concrete shrinks while it cures, these cracks are called shrinkage cracks. They usually run vertically or diagonally, are often located in the middle section of walls and are less than 1/8 of an inch wide.
Frequently you will find vertical cracks in block foundations. If the crack is located closer to a corner and is wider than 1/8 of an inch, it is probably not due to shrinkage but indicates a more serious foundation issue. If your vertical foundation crack is wider than 1/8 of an inch, call a professional to get it inspected as it may be a cause for concern.
Horizontal cracks often indicate a more serious problem. Hydrostatic (water) pressure from the outside of the walls is often the cause, and that can lead to foundation failure. Most foundations are designed to handle the pressure of water and soil. Additional pressure due to heavy rains or flooding can create serious horizontal cracks that need repairs as soon as possible.
Airlift Concrete Experts have professional solutions to fix your vertical foundation cracks once and for all. If you have small cracks and/or water seepage, we can use epoxy injections to repair a diagonal or vertical crack. Once a crack is large enough to insert a dime, you may have a foundation problem and you will need to invest in structural repairs.
Horizontal cracks on foundation walls often indicate serious problems that may eventually lead to complete foundation wall failure. If the soil around your home is not properly graded and drained, water will eventually saturate the ground around the foundation walls and increase the hydrostatic (water) pressure. If the pressure exceeds the weight-bearing capacity of the walls, it could cause them to crack or bow. Properties with clay soils that expand and contract significantly are particularly vulnerable to lateral pressure on their walls.
One of the best methods used for crack repair is epoxy injections. Epoxy injection is a system that welds the crack back together. It restores the original strength and loading of the original concrete. Epoxy injections also restore the design and structural quality and make the concrete seem as good as new. The epoxy seal makes the foundation impervious seal to air, water, chemicals, debris, and other contaminants.
Advice on the appropriate selection of film for the glass is vital to ensure that the glass does not crack as a result of thermal stress. However, it is possible that a pane of glass may break subsequent to the application of an appropriate film. One reason this happens because the pane has been damaged during the glazing of the window. Another reason is the result of the movement of the building or other physical stresses that are not apparent at the time of the application of the film.

One thing that no homeowner wants to discover in their home is hidden foundation damage. Unfortunately, the nature of houses means that damage to the foundation is always a real risk, and maintenance and inspections are among the most important things you can do to protect your foundation from a serious crack or even a complete split that causes your home to sink into the dirt. Should either of those things occur, you could find yourself looking at one of the most expensive repairs you'll need to make.
Usually, looking at your house can tell you a few things about your foundation and how sound your structure is. If you spot cracks in your home's exterior walls or an issue with your home's siding, especially if the weather has been good recently, there's a good chance that the foundation could have a problem. Other potential issues include spongy floorboards or soft spots in the ground around your house. 2ff7e9595c
