Expert Chimney Installation for Homes & Properties in Westchester County

Most people don’t think about their chimney until it stops working right. But it’s actually one of the hardest-working parts of your home. Every time you use a fireplace or wood stove, the chimney carries smoke, heat, and harmful gases safely out of the house.

A bad installation doesn’t usually show problems right away. Instead, small issues creep in over time. Smoke may blow back inside. Moisture can seep into the brickwork. Or the chimney may just never draft the way it should.

At A&GJ Construction, we build chimneys for homeowners across Westchester County using strong materials and tested building methods. We plan every project around your home, so the finished chimney stays safe for years to come.

Our Chimney Installation Services

New Chimney Installation

A new chimney system installation is easy when it’s planned as part of the project from the beginning. We construct complete chimney systems for newly built homes and properties that need a brand-new setup.

Masonry Chimney Installation

Brick, stone, and concrete blocks have been used to build chimneys for decades. They last a long time, look great on many home styles, and provide long-term durability.

Prefabricated Chimney Installation

Prefab systems are another solid choice and are often quicker to install. We fit these factory-built systems to match the manufacturer’s instructions and local building codes.

Fireplace Chimney Installation

A fireplace needs a chimney that’s matched to the way it operates. We install chimney systems for wood-burning, gas, and outdoor fireplaces, making sure each one vents properly and performs safely.

Wood Stove Chimney Installation

Wood stoves get very hot, so the venting has to be done right. We use the correct flue size and heat-resistant materials to keep things safe all winter.

Chimney Liner Installation

The liner protects the inside of the chimney. Depending on your system, we install stainless steel or clay tile liners to boost safety and help your chimney last longer.

Our Chimney Installation Process

Every job follows the same basic steps, but no two projects are the same. Careful planning
before we start helps avoid problems once the chimney is built.

Initial Consultation

We start by getting to know your property. We check the installation area, look at your heating appliance, and talk about your goals.

Site Planning

Once we’re done with the basic inspection, we move into planning. We go over material choices and chimney design.

Professional Installation

Once everything’s approved, we get to work. From setting the foundation to installing the flue, flashing, and chimney cap, every step is done carefully and follows local building rules.

Final Safety Inspection

Before finishing the job, we inspect the whole chimney. We check the draft, look over the structure, and make sure everything meets the standards.

Why Proper Chimney Installation Matters

A chimney has to safely move smoke and combustion gases out of your home. If it’s built correctly, your fireplace or heating system performs better. Professional chimney installation also helps prevent many of the issues that develop when a system isn’t planned or constructed properly.

Some of the benefits include:

Improved home safety
Efficient smoke ventilation
Better fireplace performance
Reduced fire hazards
Increased property value
Lower maintenance costs

Installing a chimney correctly the first time can save homeowners from unnecessary repairs.

Signs You Need a New Chimney Installation

Not every chimney can be repaired. In some situations, installing a new chimney is the safer and more practical solution.

A new chimney installation may be worth considering if:

You’re building a new home.
You’re adding a new fireplace.
Your existing chimney is beyond repair.
The chimney has structural damage.

If you’re unsure which option makes the most sense, a professional inspection can help you know.

Chimney Installation for Different Heating Systems

Wood-Burning Fireplaces

Wood-burning fireplaces need a chimney built to vent safely while handling high heat and smoke. We build chimneys that support a strong draft and reliable performance.

Gas Fireplaces

Gas fireplaces need a chimney that matches the appliance’s venting needs. We design ours to exhaust safely while keeping performance strong.

Pellet Stoves

Pellet stoves work differently than regular fireplaces and need the right size venting. We install chimney parts that meet the manufacturer’s specifications and local codes.

Wood Stoves

Good venting is key for a wood stove to work well. We build chimneys that safely carry smoke outside using heat-resistant materials.

Outdoor Fireplaces

Outdoor fireplaces also need a well-built chimney to help airflow and safely vent smoke away from your outdoor space while looking great too.

Chimney Safety Tips After Installation

Even a solid chimney needs a little care to perform safely and efficiently. Here’s what helps:

Get it inspected once a year.
Install a chimney cap to keep out rain, debris, and critters.
Clean out soot and creosote before it builds up.
Stick to the fuel type your appliance is made for.

Staying on top of these basics keeps your chimney running safely all year long.
