What Causes Nail Pops In An Older House?

Nail pops are a common problem in older homes. They result from the wood shrinking and contracting, which causes the nails to pop out of their holes. The term “nail pops” refers to nails coming out of wood and when they split and splinter the surrounding surface.

Nail pops in older homes is due to shrinkage and contraction in the wood, which causes nails to pop out of their holes and create an unsightly appearance and damage surfaces.

There is not much that can be done to remedy the problem, but there are a few things that you can do to prevent it from happening in the future. The most important thing is to make sure that you have enough time for your home’s wood to settle before using it or living in it.

Different types of nails that are used in construction will behave differently over time, which will influence how quickly they pop up above the drywall surface.

Reducing nail pops requires understanding what is causing them and using specific methods for prevention and correction when necessary. This article aims to explore the problem of nail pops and provide tips on how to fix them.

How To Repair Popped Nails?

Some older homes have a problem with their nails popping from the walls. This can be a result of prolonged exposure to moisture from plumbing leaks.

Other causes include age, improper installation, excessive weather exposure, and poor craftsmanship. The following section provides some tips on how to fix this problem.

You should identify the cause of the nail pops in your home. This will help you decide which course of action you want to take. For example, if it is due to excessive moisture exposure, then you should check for plumbing leaks and seal them off as soon as possible.

If there are other causes, then it will be necessary to go through a more thorough inspection process before fixing them as required by your local municipality’s building codes.

The good news is that popped nails (also called “nail pops”) aren’t too complicated to fix, and they usually aren’t serious-despite a few exceptions. Find out how to get perfectly smooth walls as well as the causes of nail pops.

Inspect Trusses, Where Uplift Can Cause Nail Pops

You may wish to investigate any bulges on your ceiling if you have noticed popped nails in your walls, as they could signal a more serious problem. Rather than building a roof from rafters, today’s homebuilders use manufactured trusses for roof construction.

Many modern drywall installers use a special adhesive technique when installing drywall on a ceiling made from trusses, as some wood members in a set of trusses shift slightly with fluctuations in attic humidity and temperature.

However, when the trusses lift, it can cause nail pops in the ceiling drywall when the drywall is attached directly to the trusses’ undersides. Depending on how much the truss moves, there may also be a horizontal crack between the wall and the ceiling.

During this process, the drywall panels should be removed, and new ones installed on clips or blocks in place of the old panels, but not the trusses.

Drywall Movement

The most common cause of nail pops is the movement of wood or drywall, which occurs within a year of construction. In addition, when the wood is stored in open-air warehouses, it can absorb moisture from the air, which can cause the wood to rot.

The wood may slowly dry in time, causing the studs to twist or move slightly after construction. The movement of nails can cause the joint compound covering drywall to come loose.

If a nail holding drywall moves, it can loosen the joint compound. In some cases, if the drywall compound comes loose and falls away, it leaves a visible nail head on the wall’s surface.

Nail pops can be caused by an imbalance of hormones and are purely cosmetic in nature. They pose no structural concerns, and they can typically be repaired with ease.

Fill Indents With Joint Drywall Compound

Screws for drywall are equipped with trumpet-shaped heads, so they can be inserted just beneath the surface. However, they will leave a small indentation if drilled completely through. Instead, use joint compound to fill indentations – about a quarter-sized glob can cover most nail and screw indentations.

Apply the joint compound using a putty knife, then smooth the excess away. Then apply a thin layer of joint compound with a putty knife after the compound has dried for at least 24 hours. When it dries, use a drywall sanding sponge to sand over the compound, and then apply another coat of paint.

In The Event Of Skimping, Add More Screws

It is possible that the drywall panel might not be securely fastened to the studs if insufficient fasteners were used, resulting in movement, and popped nails. Whenever hanging drywall, fasteners should be inserted every eight inches along the edges and every twelve to sixteen inches in the center of the panel on every stud.

For a better chance of preventing future pops, insert additional screws (one every 10 to 16 inches) over the studs if you suspect this was the case when your home was built.

Make Sure A Popped Nail Is Reinforced With The Right Length Of The Screw

It is possible to pull loose short screws beneath the drywall panel in the future, leaving you with more holes on the wall surface. Generally, screws should penetrate studs by at least 3/4 inch. A screw at least 1-1/4 inches long will be required with 1/2-inch-thick drywall, as an example.

Use Screws To Fix Popped Nails

It may solve the immediate problem if you tap the nail back down with a hammer, but eventually, the nail will probably pop back out. Taping the nail down again and inserting two drywall screws about an inch above and below the nail is a much better solution. Screws will hold the drywall panel firmly in place.

Should I Worry About Nails Popping?

There’s nothing to worry about besides the ugly nails. Nothing will happen to the drywall. Taking out the nails, replacing them with drywall screws, sanding, spackle, sanding, and painting are the steps to fix it.

Double-nailed drywall was used in well-built homes during the mid-century era. As a result, instead of one nail for each stud, two nails were used about an inch apart to hold the drywall against them.

The likelihood of nail popping is extremely low if you follow this procedure. However, the contractor who only used one nail may have been trying to save money. It doesn’t matter what the age of the house is, and if there haven’t been any recent nails popping, you shouldn’t be concerned. This won’t be an issue.

Final Words

Nail pops are caused because of the shrinking of wood around nails that have been in place for a long time. They are typically easier to fix if they are not too big. The nails can be removed, wood put back to its original shape, and the nail re-tightened.
