About Us

Our Story:
Where Soot Meets Science

The Chimney Scientists is a full-service chimney and fireplace company based in Southeastern Pennsylvania, just outside of Philadelphia, which provides general services including chimney and fireplace repairs, inspections and cleanings. We also sell and install high-quality fireplace enhancements, such as gas inserts, wood stoves, and even firewood in bulk. 

What began as a passion project for our founder, Joe, has grown into a large team of kind-hearted professionals working together to bring customers the best quality service possible, as well as a truly thorough scientific education of their chimney and fireplace.

Since our founding in 2014, the Chimney Scientists have now supported thousands of homes and families across the region, and we are continuing to apply the foremost advances that technology offers to chimneys and fireplaces. We deliver eco-friendly services to keep you and your family safe, and we’ll ensure you understand the science behind it. 

Our Founder:
Joe Ochal, a Microbiologist Turned Chimney Specialist

While working for his Uncle Bob’s fireplace showroom during his undergraduate studies, our founder gained multiple hearth & chimney industry certifications while installing and maintaining fireplace products. Upon entering his graduate education in Microbiology at Thomas Jefferson University’s College of Biomedical Sciences, Joe started the Chimney Scientists, a full-service chimney & fireplace company. With a strong set of core values the Chimney Scientists have grown to a large team of kind hearted professionals working together to bring customers the best quality service possible as well as a truly thorough scientific education of their chimney and fireplace.

Preferring a chimney brush to a lab bench, Joe still gets his scientific fix creating and funding Afrilab medical diagnostics, Valley Forge Watershed Association’s water quality testing program, and working internationally with chimney industry leaders on wood burning and moisture content testing to significantly reduce particulate emissions in a practical way. 

Core Values

Our team is strongly aligned around our core values. In fact, over the past 6 years, every employee within the Chimney Scientists has been hand-picked because they demonstrate the following characteristics:

H – Honesty & Integrity
O – Operate at the highest level
N - Never say never
O - On the spot
R - Respect the customer, respect the company, respect yourself

The Chimney Scientists always maintain a positive attitude, and we are committed to self-improvement, so that we can better support our team and our clients.

Our Investments
Beyond Chimneys

Always in Pursuit of Scientific Advancements:

While Joe pursued the Chimney Scientists as his full-time career, he and his team still strive to stay involved in the scientific community and drive advancements, where possible. In turn, under Joe’s leadership, the Chimney Scientists is a top funder and supporter of several efforts:

Afrilab Medical Diagnostics:

We created and funded Afrilab Medical Diagnostics facilities, which are modernizing the West African Health Care System. We are partnering with 47 local hospitals and 23 pharmacists to offer x-rays, ultrasounds, HIV tests and more to provide critical care. Our facilities also offer the opportunity for local educational centers to provide trainings to students, thus creating an essential training pipeline to further local health care in West Africa.

Valley Forge Watershed Association (VFWA) Project:

We work in a direct partnership with VFWA around its water quality testing program. We both recruit professors to lead the research and help purchase the equipment for the testings, which are making our watershed ecosystems safer for both people and wildlife alike.

The Firewood Project:

We are working internationally with chimney industry leaders on wood burning and moisture content testing, with the objective to significantly reduce particulate emissions in a practical way. A reduction in emissions is translating into lower costs for repairs and cleanings for home owners, as well as benefits to the planet and your personal health.

Recognizing Local Charities who are Positively Impacting Our Community

We are proud Pennsylvanians, and we have a few charities especially close to our hearts. We recognize the incredible work that they do each day, and we hope you will too.

We remain committed to donating to the following incredible charities annually:

The Susan G. Komen Breast Cancer Foundation:

Since 1982, Susan G. Komen is the largest nonprofit source funding the fight against cancer. It continues to drive research, community health, public policy initiatives and more.

Brandywine Valley SPCA:

The Brandywine Veterinary Clinic has been benefiting the area since 1929, working to end animal suffering and to ensure humane treatment. It operates as both as pet rescue and clinic to animals in needs.

Dawn’s Place:

Dawn’s Place is a non-profit proactively supporting women affected by commercial sexual exploitation. It provides direct services, raises awareness through education, and pushes for public policy reform.

Natural Lands:

Natural Lands is a nonprofit that “saves open space, cares for nature, and connects people to the outdoors” across eastern Pennsylvania. Several sites to visit include the Bryn Coed Preserve, the Willisbrook Preserve, and the Bear Creek Preserve.

We didn't know what was wrong with our chimney, but could see moisture was damaging the plaster in the ceiling around it. We consulted a roofer who said the issue was the flashing (on the roof just above the room where damage was visible). New flashing had absolutely no effect. Talked to another roofer who admitted he was stumped and recommended a company called "Chimney Scientists". Best recommendation EVER. The Chimney Scientist inspector recognized the problem immediately: unfortunate repairs in the 1980s to this chimney built in 1900 used a modern type of mortar (Portand cement) that trapped moisture inside our chimney, forcing water out through brick (and then into surrounding ceiling plaster). This past week Chimney Scientists rebuilt our chimney in the top floor of our house and up through the roof using historic lime-based mortar. They found reclaimed brick that closely matches our original brick for the exposed chimney inside the house. Above the roof, they used new brick that will resist the elements for a long, long time. End result: a gorgeous, healthy chimney inside and out. During the job, they provided thorough protection around their work area. At the end of the job, they cleaned up to perfection. All along the way, they cheerfully provided crystal clear and detailed explanations. Maybe best of all: they LISTEN. Whenever we had any concerns or questions, we were heard and any needed adjustments were made right away. The name Chimney Scientists isn't just great branding: these guys really DO understand the science behind chimneys and they take great pride in skillfully solving chimney problems. 10 stars out of 5.
