How long does a commercial roof replacement take?

The timeline depends on the square footage and material choice. Because we use our own employees rather than subcontractors, we provide predictable schedules.

Which commercial roof is best for fire resistance?

Torch Down and Metal roofing offer excellent fire protection. Slate and S-Tiles are also naturally fire-resistant.

Do you offer any guarantees on your commercial work?

Yes, we provide a 5-year labor guarantee on our installations in addition to manufacturer warranties.

Why should I avoid companies that use subcontractors?

Subcontractors lack the accountability of in-house staff. Using our own employees ensures consistent craftsmanship and safety.

Can you repair a commercial roof instead of replacing it?

Yes, we are experts in both repair and replacement and will assess if repairs can extend the life of your current system.

Expert Chimney Repair for a Safer and More Efficient Home

Your chimney is more than just a brick stack on your roof; it is a complex ventilation system designed to keep
fire, smoke, and toxic gases away from your family. Over time, exposure to the elements and high internal
temperatures can cause the structure to fail. If you have noticed falling debris in your fireplace or visible
cracks on the exterior, it is time to seek professional chimney repair. Lorens Chimney Sweep provides expert
restoration services to ensure your home stays protected and your fireplace remains a source of comfort
rather than a hazard.

Is your deteriorating chimney causing stress and safety concerns?

A damaged chimney is a silent threat. Many homeowners ignore the subtle signs of decay, only to face catastrophic results later. Have you noticed white, powdery stains on your brickwork? This is efflorescence, a sign that moisture is trapped inside the masonry. Are there small chunks of brick lying on your lawn or roof? This process, known as spalling, occurs when the freeze-thaw cycle causes water inside the bricks to expand and pop the faces off. Perhaps the most dangerous issue is a cracked flue liner. Even a hairline fracture in the flue can allow carbon monoxide to seep into your bedrooms or permit extreme heat to ignite the wooden framing of your house. These problems do not fix themselves; they only grow more dangerous and expensive with every passing season. You deserve the peace of mind that comes with knowing your chimney is structurally sound and fire-ready.

Our Proven Chimney Repair Process

We believe in transparency and precision. Every job we perform follows a strict protocol to guarantee the best
results and a spotless home.

Step 1: Thorough Diagnostic Inspection

We begin every project with a high-definition camera inspection. This allows us to see deep inside the flue and identify hidden hazards that a visual check from the ground would miss.
Step 2: Transparent Estimate and Planning

We provide a detailed report of our findings, including photos of the damage. We offer a clear, fixed-price estimate so you know exactly what the project entails before we ever strike a hammer.
Step 3: Site Preparation and Protection

We treat your home with respect. Our technicians set up drop cloths, dust containment systems, and professional scaffolding to ensure the workspace is safe and your interior remains spotless.
Step 4: Precision Execution

Our experienced masonry team performs the repairs using industry-leading materials. We follow all local building codes and National Fire Protection Association (NFPA) standards to ensure a lasting repair.
Step 5: Final Safety Verification

Once the repair is complete, we perform a smoke test to ensure the system is venting correctly and conduct a final walkthrough with you to answer any questions.

Our Comprehensive Chimney Repair Solution

At Lorens Chimney Sweep, we offer a full suite of chimney repair services designed to address every inch of your system, from the hearth to the high-point.

Professional Masonry and Tuckpointing

Mortar is the glue that holds your chimney together, but it is softer than brick and designed to wear out first. Our tuckpointing process involves carefully grinding out old, sandy mortar and injecting fresh, high-strength mortar into the joints. This restores the structural integrity of the stack and prevents water from entering the interior walls. We use specialized color-matching techniques to ensure the new mortar blends perfectly with your original architecture.

Chimney Crown Restoration and Waterproofing

The chimney crown is the concrete slab at the top of the stack. Its job is to shed water away from the masonry. If the crown is cracked, water flows straight down into the brickwork, causing rapid decay. We perform crown resurfacing using elastomeric sealants that expand and contract with the weather, or we can pour a completely new concrete crown for chimneys that are beyond simple repair.

Flue Liner Repair and Relining

The flue is the most critical safety component of your chimney. We specialize in installing UL-listed stainless steel liners that are resistant to corrosion and high heat. If your existing clay liner has minor cracks, we may use specialized ceramic coatings to seal the gaps without the need for a full replacement. A proper liner ensures a strong draft and prevents toxic fumes from lingering in your living space.

Smoke Chamber Parging

The smoke chamber is the area above the firebox where smoke gathers before entering the flue. If this area is jagged or has missing mortar, it creates turbulence and allows creosote to build up rapidly. We use refractory mortar to ‘parge’ the smoke chamber smooth, which improves airflow and reduces the risk of chimney fires.

Flashings and Leak Prevention

Water leaks often occur where the chimney meets the roof line. We install and repair custom metal flashing and counter-flashing. This creates a watertight seal that protects your attic and ceilings from water damage during heavy rainstorms.

Real Benefits of Professional Chimney Repair

Unmatched Fire Safety:

Eliminating structural gaps prevents sparks and heat from reaching the combustible parts of your home’s framing.

Moisture Protection:

Proper masonry repair stops water from destroying your walls, insulation, and the chimney itself.

Increased Energy Efficiency:

A well-repaired chimney provides a better draft, allowing your wood to burn more completely and generate more heat.

Prevent Costly Rebuilds:

Catching small masonry issues now prevents the need for a full chimney teardown and rebuild in the future.

Enhanced Property Value:

A beautiful, functional chimney is a major asset that increases the curb appeal and resale value of your property.

FAQs about Chimney Repair

How often should a chimney be inspected for repairs?

The NFPA recommends an annual inspection for all chimneys. Even if you do not use your fireplace frequently, animals, weather, and settling can cause damage that needs to be addressed before your next fire.

What are the most common signs that my chimney needs repair?

Keep an eye out for falling mortar bits in the firebox, a rusted damper, white staining on the bricks, or water dripping into the fireplace. If you smell a campfire scent when the fireplace is not in use, it often indicates a crack in the flue.

Can I just patch the cracks myself?

While DIY kits exist, they often fail to address the underlying structural cause of the crack. Professional repair ensures that the materials used can withstand thermal expansion and that the repair is airtight, which is vital for fire safety.

How long does a chimney repair project take?

Most repairs, such as tuckpointing or crown sealing, take one full day. Larger projects like chimney relining or partial rebuilds may take two to three days, depending on the height and complexity of the structure.

Is chimney repair covered by my homeowner's insurance?

Insurance typically covers damage caused by sudden events like chimney fires, lightning strikes, or severe storm damage. It generally does not cover maintenance issues caused by age or neglect, which is why regular upkeep is so important.
