Do you know if you are in need of Mercer County chimney repair? You can’t always tell by looking at it that your chimney isn’t safe and in working condition. However, there are some visible signs that indicate Mercer County chimney repair may be needed. Since chimney safety is part of safety from obvious fire hazards, every homeowner with a chimney should become familiar with telltale signs of damage.
Signs that You Need Mercer County Chimney Repair Services
- Damaged Mortar Joints: It may require a rooftop vantage point to spot, but damaged mortar joints between chimney masonry is an issue which should be hastily repaired. Failing mortar joints can mean accelerated damage to the chimney, since the condition exposes the bricks to greater amounts of moisture. When water gets into small cracks in the masonry, they can turn into large cracks, particularly as a result of freezing and thawing. Ultimately, if the problem isn’t addressed, the chimney could collapse.
- Rusted Damper or Firebox: Signs of moisture in a chimney or fireplace are red flags that the chimney isn’t operating the way it should. Rust is one clue that there is too much moisture, and you may see rust in the firebox or on the damper. You’ll know to take a close look at the damper if it becomes difficult to operate or if it isn’t sealing properly. Moisture in the chimney which causes rusting can create numerous problems, including causing flue tiles to crack. A cracked or deteriorated flue lining is highly dangerous, since it could allow too much heat into vulnerable areas and cause a house fire.
- Spalling Bricks: Spalling occurs when water enters brick, natural stone, or concrete and forces the surface of the masonry to pop out, peel off, or flake off. Sometimes salt also pushes outward from the inside and causes spalling. It’s fairly simple to spot spalling, since bits of masonry fall from the chimney. The ultimate outcome of failing to repair spalling masonry is continued crumbling and eventual destruction of the structure.
- Shaling Flue Tiles: Thin slices of chimney tile can begin to pile up at the bottom of the chimney, if the liner is damaged. Cracked and shaling flue tiles are signs of a serious condition which, if not resolved, could result in a house fire. The flue lining of a chimney must be intact in order to safely use a fireplace. Many people today are switching to stainless steel liners, which usually carry lifetime warranties. While shaling flue tiles can become evident, identifying cracked flue liners often requires an inspection by a professional chimney sweep who uses a special camera. The camera can spotlight potential problems in the flue which are difficult if not impossible to see otherwise.
- Cracked Chimney Crown: Another problem that requires a visit to the rooftop to spot is a damaged chimney crown. It’s important for the crown to be in good condition, since it provides a first line of defense against outdoor elements. When the crown is cracked, water gets in and freezes and thaws, causing larger cracks. A damaged chimney crown allows moisture to seep between the chimney and the liner as well as into the chimney, which can cause shaling and spalling. A great preventative measure against this type of damage is to weatherproof the chimney crown.
- Damaged Wallpaper: If you notice that the wallpaper is damaged in areas near the chimney, it could be because of excess moisture in the chimney. Whether the moisture problem is caused by above-named conditions or others that are less obvious, you should look into Mercer County chimney repair sooner rather than later.

Do you know if you need chimney repair in Mercer County? Many homeowners make the mistake of taking their chimney for granted by assuming that the structure is a worry-free part of the house. However, problems can arise and a chimney in need of repair should be tended to as soon as possible. A damaged chimney is a serious fire hazard. Below are some of the more obvious signs that a chimney may be damaged.
Chimney Repair in Mercer County | Efflorescence or White Staining:
White discoloration on a chimney is called efflorescence. While it’s fairly simple to remove the staining, cleaning it doesn’t solve the moisture problem which causes the white residue. Efflorescence is a clear indication of excess moisture in the masonry. If it isn’t dealt with, premature deterioration of the chimney will likely occur, in addition to other potential problems related to moisture.
Chimney Services in Mercer County | Rust:
There shouldn’t be rust on your firebox or damper. If there is, it’s a clear sign that there is excess moisture in your chimney. You may not notice rust on the damper readily but, if it doesn’t seal well or operate properly, it could be because it’s rusting. If there’s enough moisture in your chimney to cause visible signs of rusting, there could also possibly be serious damage, such as cracked flue tiles. It’s important to get the help of a professional chimney sweep, who can use a special camera to inspect the flue lining and ensure there isn’t a breach in the chimney system which could ultimately cause a house fire.
Mercer County Chimney Repair | Deteriorating Mortar Joints:
Damaged mortar joints between chimney masonry should be repaired quickly. When the mortar deteriorates, the masonry is exposed to more moisture, which accelerates the deterioration of the entire chimney. In freezing weather, the added moisture can freeze inside cracks in the masonry. When moisture thaws and freezes in bricks, rocks, and cement, larger cracks can develop. The entire chimney could collapse, if the damaged mortar isn’t repaired.
Central NJ Chimney Repair | Tile Damage:
If you start to see thin slices of chimney tile collecting in the fireplace, it’s a good indication that the flue is damaged. The flue lining is essential to the safe operation of a fireplace and chimney. Because of this fact, an annual chimney inspection is important. Professional chimney sweeps can closely analyze your flue lining and spot problems that would otherwise go undetected. For example, if the tiles are cracked but not crumbling, you probably won’t see visible signs of a breach in the chimney system.
Chimney Repair in Mercer County | Spalling:
Spalling is an issue which occurs to the outside of the chimney and can be detected because you see bits of masonry around the bottom of the structure. When moisture enters masonry, it can force the surface of the brick, concrete, or stone to peel off, pop out, or flake off. It’s essential to replace damaged masonry to prevent continued crumbling and eventual destruction of the chimney.
Chimney Repair in Central NJ | Damaged Wallpaper:
Wallpaper on the walls near your chimney can provide another visible sign of chimney damage. If the wallpaper is damaged, it is usually a result of moisture in the chimney. Repairs to the chimney or flue should be made as needed, before continuing the use of the fireplace.
NJ Chimney Repair | Chimney Crown Damage:
As with damaged mortar joints, it will be necessary to go on your roof to spot damage to the chimney crown. The crown is an important part of the chimney structure, providing a first line of defense against harsh weather conditions. If the crown is cracked, moisture could seep in and create larger cracks. A damaged crown means that water can seep between the chimney and the flue lining, which could cause spalling and tile damage.

Mercer County Chimney Liners is something that many homeowners don’t quite understand, and many times it may not seem too important! Contrary to popular understanding, a chimney liner is a vital part of every chimney. It guides smoke and other combustable materials away from the actual chimney and out into the air above. All chimneys must have an adequate working liner to maintain safety and functionality. If you are unsure whether or not you need a new chimney liner, contact your local Mercer County chimney sweep service company today!

Mercer County Chimney Liners
Today, we will be taking a closer look at the three main types of chimney liners: Clay, cast-in-place and metal liners. All three types of liner provide your chimney with adequate protection, however, depending on your individual circumstance, a certain type may be more beneficial to you.
Clay Chimney Liners – This type of liner is usually installed during the construction of a home. This is an older method of chimney lining and has been used in homes since the early 20th century. Clay tile is a tried and true type of chimney liner that is able to withstand extremely high temperatures without compromise. The clay lining is capable of resisting the harmful materials that travel up through the flue into the air above. Best of all, the clay material is very affordable and the liner can last up to 5 decades without needing to be replaced.
There are also some downsides to clay chimney liners. For starters, The clay is arranged in rectangular tiles and therefore does not create a smooth interior. Air can get stuck in the spaces and can effect the natural draft inside your chimney. If the tiles get too old, they can begin to crack which puts you at risk for a house fire. Contact your local Mercer County Chimney company to come and assess the condition of your chimney and decide whether or not you need to replace it.
Other Types of Mercer County Chimney Liners
Cast-in- liners – These liners are usually used to strengthen an existing liner inside your chimney. If your chimney. It works to reinforce the existing chimney and provides a sturdy and effective liner. Similar to the clay flue becomes misshapen, a cast in liner can create a new shape inside the flue. This type of liner is not affected by the heat or corrosive chemical that are released from combustion making them very durable. Similarly to clay liners, cast in liners can last up to 5 decades.
The installation process of cast-in liners involves a mortar mix being pumped into the chimney. This mixture is pumped around an inflated rubber balloon to create a very smooth surface inside the flue. This is an affordable and durable method and it is highly recommended.
Metal liners – Metal liners can be installed in virtually every chimney. These can be made into any size or shape. Most often, these liners are made of stainless steel. There are two major types of metal chimney liners: rigid and flexible. The shape of your chimney will dictate which type of chimney liner your chimney company will use. Rigid liners are ideal for chimneys that go straight up without any twists or bends while flexible liners can be used in chimneys with curves or bends. Insulation can also be implemented with metal liners to help to keep higher heat in the chimney and remove moisture that can cause rust and damage. It also prevents heat from moving into the pipes within the home structure. These stainless steel liners are best used for existing chimneys that either have no liner or require liner replacement.
Although there are a number of different types of chimney liners, the most importing thing is that every chimney has one. If you are unsure about the status of your chimney liner, contact your Mercer County Chimney liner company today.
