Most Common Chimney Problems


Chimney SmokeThe effect that pulls up the smoke, gases, and debris is called the draft. If the byproducts of the combustion do not exit the home, it could swell back into the room, making it dangerous. The causes of draft problems could range from construction problems and chimney physics issues such as negative pressure and stack effect.
Draft problems are very common but also difficult to diagnose. Our chimney experts have the experience as we can fix any draft problem, offer smart solutions and will never suggest redundant repairs.


Chimney CapsA chimney without a cap is not going to last without problems. Caps keep chimneys in working condition throughout the year preventing not just the destructive effects of rain but also debris or critter problems from damaging your chimney. Our lifetime warranty Stainless steel will protect your chimney and add visual appeal to your house, and the price will not burn your pockets.


Chase CoversA chase covers is a metal cover that is placed over chimney chase to avoid water from entering the chimney. Chase cover problems happened because chances are the builder used the install the cheapest quality chase covers which allow water to be accumulated leading to rust formation, debris and nests and allowing a free way for smoke and gas. The stainless steel chase covers are the best way to protect your chimney. We provide cost-effective and long-lasting stainless steel chase covers.


A chimney takes severe beating due to weather conditions throughout the year. Water entering into the chimney is the most common reason for deterioration and damage. Chimney waterproofing is a simple way to extend the lifespan of the chimney. Regular Sealers can trap the moisture, thus damaging the bricks. Instead, we use water repellent that does not trap the moisture and allows the surface to breathe, thus keeping the water at bay might not kill you, but lead to several health problems.


A damper seals off the flue from the top, thereby not allowing heat and air loss. But, when the hearth is functional, the damper needs to be open. As a result, the air can easily get in and result in heat loss. We use Lock-top-damper system that eliminates downdrafts, seals water from entering and prevents entry of pests. We can repair or replace chimney dampers at the bottom of the chimney and top sealing.


Notice a leaked ceiling around your chimney? Then you need to get your flashing checked. Chimney flashing is a metal plate situated where the chimney and roof meets. This metal plate prevents water from entering the house. Over a period of time, the metal plating, due to exposure to various elements, can get damaged, thus leading to mold formation, wall damage and rotting of wood. In case you notice water leaking from your chimney, we use ice and water shield onto the shingle underpayment and use step and counter flashing to seal the leakage.


Damaged chimney crowns are one of the major common problems. If your chimney crown is cracked, not constructed properly, or bricks are falling apart — letting water penetrate —we’ll repair or rebuild a concrete crown. Our chimney crew will seal it with a flexible sealant as it will protect the interior of the chimney from water, rain and snow. The price depends on the size of the crown and degree of repair and rebuilding.


A liner keeps the heat of the flue gases within the chimney so that the chimney does not overheat the combustible material, like the walls of the house. A secure lining system will ensure proper draft by not allowing the flue gases from expanding and cooling more than required.

Reasons for lining or relining your chimney include:

1. Properly sizing (by reducing) the chimney flue. Proper sizing assures better draft, other edges along with less creosote

2. Cracks or defects. Having a lining within your chimney assures the fire will remain in a tightly sealed tube – and additionally transfer less heat through the wall of the chimney to nearby framing and combustible material.

3. Some older chimneys were constructed free of liner of brick – and some newer chimneys have broken and deteriorated clay liners. Both of these pose safety risks.

Why does a chimney need cleaning and inspection?

Before you spend money, we think you should also know: Can a chimney really catch fire?

When you use your chimney, you are burning a fire inside of your house. So, your chimney needs to be in safe working conditions to prevent fire dangers.

Why does a chimney catch fire?

When you burn wood in the fire-place it creates deposits of soot and creosote inside the chimney flue. Over time this flammable build up will eventually ignite and cause a chimney fire.

Chimney Sweeping MarylandWhat happens when a chimney catches fire?

A Chimney in perfect conditions can handle a flue fire. So, what is the danger then? Well, a chimney is prone to have construction defects and easily develop cracks and other damages over time. A chimney that has not yet been inspected may have problems which may allow an eventual fire to escape into the house

Dryer Vent Problem List Will Help You Understand Dryer Vent Problems

Do you have a dryer vent problem? The list will help will understand your dryer vent problems.

Longer drying times are an indication that airflow in your dryer vent is constricted. Inadequate airflow can be the result of a clog or obstruction in your dryer vent system. Excess dryer lint is a major fire hazard, it can cause your dryer to become damaged and reduces the efficiency of your dryer.

Lint behind dryer

It’s usually the vent not your dryer. An accumulation of excess lint behind your dryer can be the result of a clogged dryer vent. Since a clogged vent restricts airflow so that the air cannot move the lint to the outside of your home, it forces the lint into the area behind your dryer.

Dryer repeatedly stops, turns off during a cycle.

If your dryer stops repeatedly during a normal drying cycle, it is typically due to the dryer overheating. A dryer vent clogged with lint or other obstructions will force the dryer to work harder, causing the unit to overheat. The overheat shutoff is the dryer’s last attempt to prevent a fire.

There is excess lint left on your clothing.

Excess lint on clothing after a dry cycle is a sign of accumulation of lint in your dryer vent. A dryer vent clogged with lint is a fire hazard and an energy hog.

Clothes are very hot after a dry cycle.

The cause for this problem could be poor ventilation caused by a dryer vent clogged with lint, a bad vent connection, or a dryer vent joint that is not secure. These problems are not only a fire hazard, but also the overheating can damage the clothing as well as the dryer.

Clothes have a moldy smell after dry cycle.

When a dryer vent is clogged, the humidity removed from your wet clothes cannot exhaust through the vent so it back is out in the and collects in the duct creating the perfect growing conditions for mold and mildew. If you notice a moldy smell in your laundry room, have your dryer vent inspected immediately.

Water stains in the wall near the dryer appliance.

If the dryer duct runs behind the wall where you see water marks, it could be a clogged duct and condensation is leaking through the duct connections.

How do I know when it is time to clean my dryer? And how often do I need my dryer vent cleaned?

You can ask that question to Robert DeNiro!

Robert De Niro’s Central Park West apartment went up in flames when lint in a clothes dryer caught fire a few years ago.
“Right above my head these 12-foot-tall flames exploded out of the 5th floor window,” said Nathan Bear, 23, who was outside moving his car.
The fire started around 2 p.m. in a pricey high rise near West 68th Street and took firefighters an hour to get under control, officials said.
“The dryer in 5W caused the fire that spread through the entire 5th floor,” said Battalion Chief Mike Meyers.
Meyers, a firefighter at the scene said, “Some of the lint [in the dryer] caught fire.”
The 5th floor had extensive damaged from the fire, smoke and water, fire department officials said. The 4th and 6th floor apartments were also damaged in the all hands fire, Meyers said.

Did you know that dryers cause more fires than chimneys?

There is no way to know when a fire can sneak up on you, that’s why the manufacturers and fire departments recommend early cleaning and inspection as the only prevention.

“I clean out the lint screen every time I dry clothes. Why isn’t that enough?” It’s not enough, most of lint gets past the lint screen and accumulates in the air ducts.

Dryer vents require regular service for safety assurance. But your dryer is at a greater risk if:

• Clothes are hot but still damp after one cycle.
• your dryer takes more than one cycle to dry¬
• Dryer is hot to the touch
• Lint accumulates around/behind dryer. ¬¬
• Laundry room is humid or warm when dryer is in use
• Musty smell coming from dryer

In average there are about 12,700 clothes dryer fires a year resulting damages, 330 injuries, and 20 lives lost.
