Professional Chimney Repair in Rockville, MD
A chimney does more than provide a place for smoke to escape. It is an important part of your home’s heating and ventilation system, while the exterior masonry protects the structure from weather, moisture, and long-term deterioration.
In Rockville, MD, seasonal temperature changes, rain, snow, ice, humidity, and freeze-thaw cycles can contribute to chimney damage over time. Older masonry chimneys may develop cracked mortar joints, spalling bricks, deteriorating crowns, damaged flashing, or water intrusion. Even newer chimneys can develop problems when components are improperly installed or exposed to repeated weather conditions.
Our Rockville chimney repair services are designed to identify the source of the problem instead of simply treating the visible symptom. We inspect the chimney, explain what we find, and help you determine which repairs make sense for your home.
Whether you need chimney masonry repair, chimney leak repair, chimney crown repair, chimney flashing repair, tuck-pointing, chimney cap replacement, or chimney liner repair, Giross Chimney & Duct Services is ready to help.
We Are Open! WEEKEND APPOINTMENTS AVAILABLE.

Chimney Crown Repair in Rockville, MD
The chimney crown sits at the top of a masonry chimney and helps direct water away from the structure. When the crown cracks, deteriorates, or is improperly constructed, water can enter the masonry and contribute to extensive damage.
A cracked chimney crown in Rockville should not be ignored.
Our chimney crown repair service can include inspection of existing cracks and deterioration, repair of damaged areas, replacement when necessary, and recommendations for protecting the crown from future moisture exposure.
If you notice cracks around the top of your chimney or water-related damage inside your home, ask about a chimney crown inspection and repair.
The objective is simple: stop water from reaching the masonry and help prevent the same deterioration from continuing.

Chimney Masonry Repair in Rockville
Masonry deterioration is one of the most common reasons homeowners need chimney repair in Rockville, MD.
Over time, mortar joints can deteriorate and bricks can crack, absorb water, or begin to spall. When damaged masonry is left untreated, moisture can penetrate deeper into the chimney structure and accelerate deterioration.
Our chimney masonry repair services focus on restoring damaged brick and mortar while addressing the underlying source of the problem whenever possible.
Depending on the condition of your chimney, repairs may include replacing damaged bricks, repairing mortar joints, tuckpointing, rebuilding sections of masonry, repairing the chimney crown, or applying appropriate waterproofing.
The goal is not simply to make a chimney look better. Proper masonry repair helps protect the structure and extend the useful life of your chimney.
Chimney Tuck-pointing & Mortar Joint Repair
Deteriorating mortar joints can allow water to enter the chimney and surrounding masonry. In some cases, the bricks remain in reasonable condition while the mortar holding them together has begun to fail.
Chimney tuckpointing and repointing in Rockville can restore deteriorated mortar joints and help prevent further water intrusion.
During a chimney masonry inspection, we look for open joints, cracking, crumbling mortar, loose bricks, and areas where previous repairs may have failed. When appropriate, deteriorated mortar can be removed and replaced with compatible new mortar.
This type of chimney repair in Rockville, MD can be an important preventative measure for homeowners who want to address masonry deterioration before a larger rebuild becomes necessary.
The goal isn’t to rebuild what doesn’t need rebuilding. It’s to repair the damaged masonry and protect the sound structure that remains.
Don’t let your chimney get worse! Emergency calls welcome.
Chase Cover Installation & Replacement
A damaged or poorly fitted chase cover can allow water to enter your chimney system and lead to costly damage. The chase cover sits on top of a factory-built chimney enclosure and is designed to direct rain and snow away from the chimney. Over time, exposure to moisture can cause rust, corrosion, cracks, failed seams, or separation that allows water to penetrate.
At Giross Chimney & Duct Services, we inspect the chase cover and surrounding areas to identify signs of deterioration and potential moisture entry. If the existing cover can be repaired, we recommend the appropriate repair. When replacement is necessary, we install a properly fitted chase cover designed for reliable drainage, weather resistance, and long-term protection.
Warning signs may include rust, water stains, ceiling leaks, moisture around the fireplace, damaged flashing, or visible deterioration around the chimney top. Addressing these issues early can help prevent water from spreading into the chimney, walls, ceilings, insulation, or surrounding structure.
We provide chase cover installation and replacement throughout Maryland, Washington, DC, Northern Virginia, Montgomery County, and surrounding communities.
Don’t let a damaged chase cover become a bigger chimney problem.
Protect your chimney and your home with professional chase cover installation and replacement.

Chimney Flashing Repair
The flashing where your chimney meets the roof plays an important role in keeping water outside your home.
Damaged, loose, improperly installed, or deteriorated chimney flashing can create leaks that are difficult to identify from inside the house.
Our chimney flashing repair in Rockville focuses on identifying potential points of water entry and repairing or replacing damaged flashing when necessary.
Because chimney leaks can originate from multiple areas, we look at the chimney and roof intersection as part of the overall evaluation rather than assuming every leak comes from the chimney crown.
A chimney leak should be repaired at the point where the water is entering — not where the water happens to appear inside your home.
Act now for a free consultation!
Chimney Liner Inspection & Repair
The chimney liner is an important component of a properly functioning chimney system. Damage, deterioration, gaps, or other liner problems can affect the safe operation of your fireplace or heating appliance.
If you are experiencing smoke-drafting issues, have an older chimney, are changing heating appliances, or have been advised that your chimney liner needs attention, a professional chimney liner inspection in Rockville can help determine the condition of the flue.
Depending on what the inspection reveals, solutions may include flue tile repair, chimney relining, or other appropriate repairs.
Our approach is to evaluate the existing system and recommend the repair that fits the actual condition of the chimney.
Chimney Leak Repair in Rockville, MD
A leaking chimney can cause damage far beyond the chimney itself.
Water may enter through damaged flashing, cracked masonry, an aging chimney crown, deteriorated mortar joints, missing or damaged chimney caps, or other areas around the roofline. The resulting moisture can eventually affect ceilings, walls, insulation, framing, and interior finishes.
Our chimney leak repair in Rockville, MD starts by looking for the source of the water rather than simply sealing the most obvious area.
We can inspect the chimney exterior, masonry, crown, cap, flashing, and surrounding roof area to help determine where moisture may be entering.
If you have noticed a water stain near your fireplace, dampness around the chimney, peeling paint, musty odors, or visible exterior masonry damage, schedule a chimney inspection before the problem becomes more serious.
Appointment in the next 24 hours. Call us now.
Chimney Restoration
Sometimes a chimney doesn’t have just one problem. Years of rain, snow, freezing temperatures, and moisture exposure can damage multiple components, including the bricks, mortar, crown, cap, flashing, and chase cover. What may look like a small repair can sometimes indicate a larger water-intrusion or deterioration issue.
That’s why comprehensive chimney restoration is often the better approach. Instead of addressing only the most visible damage, we evaluate the chimney as a whole to identify areas that have deteriorated and determine how the different issues may be connected.
Restoration may include masonry repair, repointing, brick replacement, crown repair or replacement, cap replacement, chase cover replacement, flashing repair, waterproofing, and rebuilding of severely damaged sections.
When deterioration has progressed beyond a simple repair, rebuilding may be necessary to restore the affected portion properly and provide long-term stability and protection.
The goal of restoration is not simply to make an aging chimney look new. It is to repair damaged areas, address potential sources of moisture intrusion, strengthen vulnerable components, and improve the chimney’s protection against the elements.
Every chimney is different, so the right restoration plan depends on its existing condition. A thorough evaluation helps determine which repairs, replacements, or rebuilding are necessary to restore the chimney properly and extend its service life.
Get help now! Same-day service available.
Chimney Rebuild & Structural Repair
There are times when deterioration has progressed beyond a simple repair.
Loose masonry, extensive brick deterioration, major structural damage, or a chimney that has begun to lean may indicate that a section needs to be rebuilt.
Before recommending a major reconstruction, we evaluate the condition of the chimney and determine how extensive the damage actually is.
If only part of the structure is affected, a partial rebuild may be possible. If the deterioration is more extensive, a larger reconstruction may be necessary.
The important thing is to determine the condition of the chimney before deciding how much work it needs.
Our approach is to repair what can be properly repaired and rebuild only what requires rebuilding.

Signs You May Need Chimney Repair
How do you know when it is time to call a chimney contractor?
Some chimney problems are obvious, while others develop slowly. Contact a professional if you notice:
Cracked chimney bricks: Cracks can allow water to penetrate the masonry and may indicate deterioration.
Crumbling mortar: Deteriorating mortar joints can allow moisture into the chimney structure.
White staining on bricks: White or chalky deposits can be a sign of moisture moving through masonry.
Water around the fireplace: Interior moisture may indicate a chimney leak.
Damaged chimney crown: Cracks or deterioration at the chimney top can expose the masonry to water.
Loose or missing chimney cap: An unprotected chimney opening can allow rain, debris, and animals into the system.
Smoke entering the room: Drafting problems can have multiple causes and should be professionally evaluated.
Damaged flashing: Problems where the chimney meets the roof can lead to persistent leaks.
Deteriorating chimney liner: Flue problems can affect the safe operation of the chimney.
If you have noticed any of these warning signs, scheduling a Rockville chimney inspection can help determine what needs to be repaired.

Frequently Asked Questions About Chimney Repair in Rockville, MD
How much does chimney repair cost in Rockville, MD?
The cost of chimney repair varies considerably depending on the type and extent of damage. A small mortar repair, chimney cap replacement, or minor crown repair will typically involve a very different scope of work than a chimney rebuild or extensive masonry restoration.
The best way to determine the cost of your chimney repair in Rockville is to have the chimney evaluated and receive a project-specific estimate.
What is the most common chimney repair?
Common chimney repairs include masonry and mortar repair, tuckpointing, chimney crown repair, flashing repair, chimney cap replacement, leak repair, and chimney liner work.
The appropriate repair depends on the condition and construction of your individual chimney.
How do I know if my chimney is leaking?
Signs of a chimney leak can include water stains around the fireplace, dampness near the chimney, deteriorating masonry, damaged flashing, staining on the ceiling or walls, or moisture-related odors.
Because water can travel from the original entry point, identifying the source may require a detailed chimney and roofline inspection.
Can cracked chimney bricks be repaired?
In some situations, damaged bricks can be removed and replaced while surrounding masonry is preserved. The appropriate repair depends on the severity and location of the damage.
A professional chimney masonry inspection in Rockville can determine whether localized brick repair, mortar repair, or a larger masonry restoration is appropriate.
Does chimney flashing need to be replaced?
Not always. If flashing is damaged, improperly installed, deteriorated, or allowing water into the home, repair or replacement may be necessary.
An inspection can help determine whether the problem is actually the flashing or another component such as the chimney crown or masonry.
Should I repair or rebuild my chimney?
That depends on the condition of the chimney. Some chimneys can be restored with localized masonry repairs, tuckpointing, crown work, flashing repair, or waterproofing. Severely deteriorated structures may require partial or more extensive rebuilding.
A professional evaluation is the best way to determine which option makes sense.
How often should a chimney be inspected?
Inspection needs vary depending on how the fireplace and chimney are used, the type of appliance, the chimney’s condition, and other circumstances. Homeowners should follow applicable safety recommendations and have their chimney professionally evaluated when problems are suspected or when changes are made to the system.
