Chimney Inspection (Level 1 & Level 2)

A full chimney inspection is essential for ensuring safe operation, preventing hidden hazards, and identifying structural issues before they become expensive repairs.
Our certified inspection includes a complete evaluation of the chimney’s interior and exterior, flue system, smoke chamber, crown, cap, and all accessible components.

Level 1 Inspection (Standard Annual Inspection)

Ideal for homes using the same appliance with no major changes. We check:

• Structural integrity of the chimney

• Creosote buildup or blockages

• Condition of the flue liner

• Damper operation

• Visible leaks, cracks, or deterioration

• Firebox and smoke chamber condition

Level 2 Inspection (Real Estate / Major Changes / Damage Check)

Required for home purchases, installation changes, chimney fires, or storm damage. Includes everything from Level 1 plus:

• Video camera inspection inside the flue

• Full scan for hidden cracks or liner damage

• Inspection of attic, crawl space, or basement areas near the chimney

• Verification of code compliance

• Safety evaluation for insurance or real-estate documentation

Our detailed inspection report helps homeowners understand the exact condition of their chimney and what repairs or maintenance are needed to keep the system safe.

Chimney Sweep / Cleaning – Deep Professional Cleaning

A clean chimney means a safe home.
Our chimney sweeping service removes creosote, soot, blockages, ash buildup, animal nests, and dangerous debris that can cause fires, smoke backup, and poor fireplace performance.

We use professional rotating brushes, vacuums, inspection lights, and dust-control systems to clean the entire flue from top to bottom — with no mess left behind.

Perfect for wood-burning fireplaces, gas fireplaces with residue issues, or chimneys that haven’t been serviced recently.

Results:
✔ Safer operation
✔ Reduced fire risk
✔ Better airflow
✔ Cleaner, more efficient fireplace performance

Premium service, spotless results

Air Duct Cleaning (Full HVAC System Cleaning)

Breathe Cleaner, Healthier Air With a Professional Deep-Clean of Your Entire Duct System

Over time, your home’s air ducts collect dust, pet hair, allergens, mold spores, bacteria, and debris that circulate back into the air your family breathes. A dirty duct system also forces your HVAC unit to work harder, raising energy bills and shortening the lifespan of your system.

Our Professional Air Duct Cleaning removes all buildup inside the ductwork and boosts indoor air quality immediately. We use high-power negative pressure vacuums and rotary brush systems to deep-clean every vent, return line, and trunk line.

Includes:
✔ Full inspection of supply & return ducts
✔ High-suction negative air machine for maximum debris removal
✔ Rotary brush agitation to break down heavy dust buildup
✔ Cleaning of vent covers, grills, and registers
✔ Sanitizing treatment available (kills bacteria & mold spores)
✔ Airflow improvement throughout the home
✔ Safe for kids, pets, and allergy-sensitive individuals

A complete duct cleaning leaves your home smelling fresher, improves HVAC efficiency, and helps prevent respiratory irritation caused by contaminated air.

Professional Dryer Vent Cleaning (Fire-Safety Service)

Lint buildup inside a dryer vent is one of the leading causes of house fires in the U.S. Over time, dust, lint, and debris restrict airflow, force the dryer to work harder, and create dangerous heat inside the vent line.

Our professional dryer vent cleaning service removes all lint and obstructions from the entire vent run — from the back of the dryer to the outside termination. We use commercial-grade rotary brushes and high-powered vacuums to clean the vent thoroughly without making a mess in your home.

What you get:

• Reduced risk of dryer-vent fires

• Shorter drying times and lower energy bills

• Less wear and tear on your dryer

• Improved airflow and performance

• A clean, code-compliant vent system

Recommended every 12 months, or any time you notice long drying cycles, excess heat, or burning smells around the dryer.

Premium Stainless-Steel Chimney Cap Installation

A properly installed chimney cap is one of the most important components for protecting your entire chimney system.
Our team installs high-quality stainless-steel caps that provide long-term defense against rain, snow, animals, debris, and downdrafts.
Moisture entering an unprotected chimney can lead to rusted dampers, damaged flue tiles, mold, odors, and structural deterioration.
We custom-measure every chimney, secure the cap professionally, and ensure it is built to withstand Missouri weather year-round.
A premium cap increases safety, extends chimney life, and prevents expensive water-related repairs.

Chimney Leak Repair – Stop Water Damage Fast

Water intrusion is one of the most serious threats to any chimney system.
Our team pinpoints the exact source of the leak—whether it comes from cracked bricks, deteriorated mortar, a damaged crown, faulty flashing, or missing waterproof protection.

We provide a full, professional repair that includes sealing, rebuilding weak areas, and applying long-lasting waterproofing designed to protect your home from structural damage, mold, stains, and future leaks.

Reliable, expert repair that keeps your chimney strong, dry, and safe.

Chimney Crown Repair & Waterproofing

Protect Your Chimney From Water Damage, Cracks, and Structural Failure

Your chimney crown is the first line of defense against rain, snow, and moisture.

When it cracks —even a little —water begins to seep inside the structure, causing expensive interior damage, brick deterioration, mold, and leaks inside the house.

We provide premium chimney crown repair and full waterproof sealing using high-grade, commercial materials designed to last for years in Missouri weather.

Our work includes:

• Repairing cracks and structural weak points

• Applying a professional waterproof barrier

• Smoothing and sealing the entire surface for long-term protection

• Preventing future leaks, brick damage, and costly repairs

• Ensuring your chimney stays safe, solid, and weatherproof

This is one of the most important maintenance services for any chimney — protecting your home from the #1 cause of chimney damage: water infiltration.

Chase Cover Replacement (Premium Stainless Steel)

Protect Your Home With a Fully Upgraded, Leak-Proof Stainless Steel Chase Cover

A damaged or rusted chase cover is one of the biggest causes of chimney leaks.
Once water enters through the top of the chase, it can destroy the framing, rot the wood structure, cause mold growth, stain ceilings, damage drywall, and lead to major interior repairs.

Our Premium Stainless Steel Chase Cover Replacement gives your chimney full top-side protection with commercial-grade materials that will never rust, warp, or corrode — even in the harsh St. Louis weather.

We custom-size and install the cover to perfectly fit your chase, ensuring a clean, modern look and long-lasting durability.

Includes:
✔ Removal of old, rusted, or damaged chase cover
✔ Precision measurement for a perfect custom fit
✔ Installation of a premium 24-gauge stainless steel cover
✔ Reinforced drip edges to keep water away from the chase
✔ Optional pest-proof screened cap
✔ Full waterproof sealing for maximum protection
✔ Clean, high-end finish that upgrades the home’s exterior

A new stainless steel chase cover not only stops leaks — it protects your home for decades and instantly improves curb appeal.
