How do I know if my chimney needs repairs vs. a full rebuild?

The difference usually comes down to whether the damage is surface-level or structural. During our video inspection, we'll show you exactly what's going on inside and outside the chimney and recommend the most practical solution. Here are the general indicators we look for:

• Targeted repairs are usually sufficient when damage is limited to mortar joints, isolated spalling bricks, a cracked crown, or worn flashing.
• A partial rebuild may be needed when several courses of brick above the roofline have deteriorated but the lower structure is sound.
• A full rebuild is typically required when the internal flue, foundation, or supporting masonry has been compromised by long-term water intrusion or settling.

A Level 2 video inspection (which we include as part of our assessment) allows us to identify hidden damage inside the flue that isn't visible from the outside, so nothing gets missed. Most homeowners are surprised to learn that what looks like a major problem can often be fixed with targeted repairs rather than a complete overhaul - and we'll always recommend the least invasive option.

What type of chimney leak repairs do you offer?

Water is the single biggest threat to the long-term health of your chimney, and leaks can originate from several different areas. We specialize in diagnosing and repairing all types of chimney leaks, including:

• Chimney crown repair: The crown is the cement slab that seals the top of the chimney structure. Cracks allow water to seep directly into the masonry.
• Flashing repair or replacement: Flashing is the metal seal where your chimney meets the roofline. Gaps, rust, or improper installation are among the most common sources of water entry.
• Mortar joint repointing: Over time, mortar between bricks erodes and cracks, creating entry points for water.
• Chimney cap or chase cover replacement: A missing or damaged cap allows rain, snow, and debris to fall directly into the flue.
• Waterproofing treatment: Once leak sources are repaired, we apply a vapor-permeable waterproofing sealant to the exterior masonry to prevent future water absorption without trapping moisture inside.
• Interior damage assessment: If water has already penetrated, we inspect and address any resulting damage to the flue liner, smoke chamber, firebox, or damper.

Why are stainless steel chimney liners recommended?

Stainless steel chimney liners are widely considered the gold standard for chimney lining systems, and for good reason. Whether you're replacing a deteriorated clay tile liner or installing a liner in a previously unlined chimney, stainless steel offers a range of safety, performance, and longevity advantages:

• Superior corrosion resistance: The byproducts of combustion are highly corrosive. Stainless steel is designed to withstand these chemicals over the long term, whereas clay tile liners can crack and deteriorate under the same conditions.
• Improved draft and efficiency: A properly sized stainless liner creates a consistent, well-defined flue path that promotes efficient draft.
• Reduced creosote accumulation: The smooth interior surface of a stainless liner discourages creosote from adhering to the walls, lowering the risk of dangerous chimney fires - and making annual cleaning faster and more effective.
• Versatility across fuel types: Stainless steel liners can be used with wood-burning fireplaces, gas inserts, oil furnaces, pellet stoves, and more. We match the liner grade and diameter to your specific appliance.
• Code compliance: Most local building codes and NFPA 211 standards require a properly installed liner for new appliances and liner replacements. Stainless steel liners meet or exceed these requirements.
• Long service life: A quality stainless steel liner, properly installed and maintained, can last 20 years or more - often outlasting the appliance it serves.

We install flexible and rigid stainless steel liner systems and can advise you on the right option based on the configuration of your chimney and the type of heating appliance you use.

Can I waterproof my chimney myself?

While it may be tempting to treat chimney waterproofing as a straightforward DIY project, we strongly advise against it. Chimneys require a very specific type of waterproofing that differs fundamentally from standard masonry or exterior sealants. Here's why professional application matters:

• Vapor permeability is essential: Brick and mortar naturally contain moisture. A chimney waterproofing product must be vapor-permeable - meaning it allows trapped moisture to escape outward while preventing new water from entering. Standard hardware-store sealants are typically film-forming and non-permeable, which traps moisture inside. This leads to freeze-thaw damage, accelerated spalling, and potentially serious structural deterioration.
• Surface preparation is critical: Before any waterproofing product is applied, the masonry must be clean, dry, and free of existing sealants, efflorescence, and biological growth. Skipping this step renders the treatment far less effective and can cause adhesion problems.
• Underlying issues must be addressed first: Waterproofing is not a substitute for repairing cracked mortar joints, damaged crowns, or faulty flashing. Applying a sealant over existing damage simply delays the inevitable - and often makes future repairs more difficult and expensive.
• Improper application can void warranties: Some chimney manufacturers and liner installers specify approved waterproofing methods. Using an incompatible product can void coverage on recently installed components.

Our waterproofing service includes a full inspection, any necessary repairs, thorough surface preparation, and professional application of a vapor-permeable sealant, giving you long-lasting protection done right the first time.

What are chimney caps and what do they do?

Chimney caps are one of the most cost-effective protective accessories you can add to your chimney system. Installed at the top of the flue opening, they serve multiple important functions that protect both the chimney and your home:

• Water protection: Rain and snow falling directly into an uncapped flue saturate the liner and masonry, leading to rust, mortar deterioration, and freeze-thaw damage over time. A chimney cap deflects precipitation while still allowing exhaust gases to escape freely.
• Animal and pest exclusion: Birds, squirrels, raccoons, and other animals are attracted to the warmth of an open chimney flue. Once inside, they can build nests that block the flue, create fire hazards, and introduce parasites. A properly fitted cap with a mesh screen prevents entry entirely.
• Debris prevention: Leaves, twigs, and other debris can accumulate inside an uncapped flue and restrict airflow, causing smoke to back up into your home. Caps keep the flue clear between uses.
• Spark arrestor function: The mesh screen on most caps catches burning embers before they can escape the flue and land on the roof or surrounding landscape, reducing the risk of roof fires or grass fires during use.
• Draft improvement: Certain cap designs can help stabilize draft by reducing the effect of wind downdrafts that push smoke back into the home.
• Extended chimney lifespan: By keeping water, animals, and debris out of the flue, a chimney cap helps preserve your liner, smoke chamber, and firebox - reducing the frequency and cost of repairs over the long run.

Can I use a chimney that doesn't have a liner?

No. A chimney liner is not optional - it's a critical safety and performance component of any functioning chimney system. Here's a closer look at why liners matter and what to expect:

• It's required by code. Modern building codes and NFPA 211 standards require a properly sized and intact liner for most heating appliances. Operating without a functioning liner may affect your homeowner's insurance coverage.
• It protects your masonry. Without a liner, combustion gases come into direct contact with your chimney's brick and mortar. This causes rapid deterioration from the inside out, eventually compromising the structural integrity of the chimney.
• It helps prevent carbon monoxide intrusion. A cracked or missing liner can allow carbon monoxide and other combustion gases to seep through the chimney walls and into living spaces.
• It reduces creosote buildup. A properly sized liner creates the right draft conditions for complete combustion, which minimizes the production and accumulation of creosote.
• It improves heating efficiency. An appropriately sized liner ensures that your appliance drafts correctly, maximizing heat output and fuel efficiency.

If you're unsure whether your existing liner is intact or properly sized for your appliance, our video inspection will give you a definitive answer. We'll assess the condition of the liner from top to bottom and let you know whether a repair or replacement is the right course of action.
