Drywall Cracks: Cosmetic Or Structural

Cracks in the drywall and plaster are a very common occurrence. They occur over time when there is stress or even a little settlement of the home. Contractors may call them hairline cracks, meaning that they are very thin looking. The majority of the time they are considered cosmetic and can be covered over when repainting is done.

Where do you often see drywall cracks?

These cracks are most commonly seen in areas where the structure develops more stress than other areas. The most common areas are the corners of doors and windows as well as the corners of wall openings. This is true of both exterior and interior doors and openings.

Another common place to see these cracks is where two pieces of drywall come together. These cracks usually run either horizontal or vertical at the drywall seams. Homes with vaulted ceilings may develop these cracks in the higher areas as well.

Additionally, drywall cracks are often found where two pieces of drywall are butted together. This occurs because there is a joint, which gets drywall taped and then layered with two or three coats of drywall mud. These joint areas are weaker than in the center, or field area of the drywall, therefore some cracks may occur at these joints.

Common causes of drywall cracks

As previously mentioned, stress is usually the main reasons that cracks occur. However, there are many potential causes of stress; some of the more common ones are:

Wood framing drying out; the wood cures or loses moisture as it ages, causing the lumber to twist or warp a little and even a little dimensional change occurs.
Movement of the structure:

1. Wind loads from storms, creating stresses on walls and ceilings

2. Settling of the home or soil movement

3. Expansive soils pushing up on the structure

4. Wet and dry seasons

5. Extreme below freezing temps like we experienced in Fort Worth, Texas this past February

6. Expansion and contraction due to hot and cold weather (this can be common in vacation homes and homes that have been left vacant due to the fact that the internal temperature of the home has been allowed to get higher and lower depending on the outside temps)

7. Earthquakes – if the home is in an area that has trimmers or earthquakes

8.  Truss uplift – can create cracks where interior walls meets ceiling

9. Poor quality workmanship in taping the drywall joints. (Too much mud, too little mud, missing drywall tape, and drywall secured with internal stresses are some causes)

Removal of “Pop-corn,” textured or “cottage cheese” looking ceiling material may leave a drywall taping job that tends to crack at the drywall joint. This often happens because the home builder knew that they were going to texture the ceiling, so they had the drywall contractor put on less coats of drywall mud over the joints since it would save money and would be covered with a textured material. i.e. a “pop-corn” ceiling material. With fewer coatings over the joints, the more likely a crack will develop.

Some cracks may be a “Red” flag under a few circumstances.

Wide cracks or cracks that run at an angel or diagonally may be a “Red” flag.  It is important to note that while these cracks should be looked at more closely, these types of cracks may not be serious. Whether or not these cracks are serious is dependent on the particular circumstances.

If concerned, do a quick structural check of the home

First step outside the home and walk around the exterior; check for:

Cracks in the foundation or is it bowed or leaning
Cracks in the siding or stucco (a few small cracks are common)
Does the roof sag or is it bowed
If there is a basement, check for cracked or bowing walls

Walk around the inside:

Are the floors level or sloping
Do any doors rub the flooring
Are any doors or windows sticking
Look for sagging ceilings and bowed walls

The above items can be an indication that a structural issues may exist, depending on the location and severity. If so, some of these issues may need to be addressed to help keep the drywall cracks from coming back.

Who can fix drywall cracks?
Handymen, homeowners, painters or drywall tapers

For the majority of cracks a painter would be the appropriate person to seal and cover the cracks. At times, a drywall contractor or a skilled handyman who can tape and mud joints may be needed. There are many products that can be used such as mesh tape, mesh patch kits, drywall mud and caulking. In some instances depending on the type of texture on the wall, it may be difficult for the homeowner to properly match the existing texture pattern. In this case an experienced drywall contractor is recommended although the majority of small cracks can be filled and repainted such that they cannot be noticed easily. By using a mesh tape product the crack is less likely to show up again. Simply applying some drywall mud or spackle will not be very strong and you may find that even the normal expansion and contraction from temperature fluctuations may be enough to cause the crack again.

Finding the right painting contractor is not easy, and the decision should not be made on cost alone. One way to ensure a good experience is to contact a company like Eagle Painting Company, which has years and years of experience and is a solid part of the community with a great deal to lose if they do not do an excellent job in the time they promised and at the price agreed to.
