What Is Chimney Certification?

A chimney certification is a formal document issued by a licensed chimney inspector stating that the chimney or venting system is safe, structurally sound, and properly venting combustion gases. This certification is especially important in homes with gas or oil appliances.

Home sales or purchases

Home owner’s insurance documentation

Cracked flue liners

Improper venting or drafting

Blockages and buildup

Appliance upgrades or fuel conversions

Flue sizing compliance

Damage from prior chimney fires

Why It’s Required in New Jersey

 Why It’s Required in New Jersey

The New Jersey Uniform Construction Code (NJUCC) requires chimney certification any time fuel-fired appliances are replaced or modified, including:

Oil-to-gas conversions

Replacing furnaces or boilers

Water heater upgrades

Adding a new fuel-burning appliance

Before a new unit is activated, a certified professional must inspect the existing chimney and submit the Chimney Verification Form (UCC F-370) to confirm it meets safety and performance standards. Download NJUCC Form F-370 (PDF)

Who Needs Chimney Certification and Why

Many property owners and buyers assume a home inspection is enough. However, general inspectors do not have the tools or training to evaluate chimneys thoroughly. That’s where we come in.

You should request chimney certification if:

You’re selling a home and want to avoid closing delays

You’re buying a home with an active or in active fireplace or wood stove

Your insurance provider requires proof of chimney integrity

You’re installing a new fireplace insert or converting from wood to gas

You’ve recently experienced a chimney fire or water intrusion

1 Hour Chimney delivers professional certifications accepted by realtors, lenders, insurers, and code officials.

These guys are pros.The people in the office pick up the phone (unlike many other contractors) and are straightforward and friendly. The crew explained my options and were very clear about everything they were doing. The boss (over the phone) cleared up any issues I had and did everything to have me as a happy customer. The chimney cap looks perfect and the upgraded water heater and boiler lines look great.Great quotes, great price, great work, friendly people.I wonder if they do other work besides chimneys?

How we work:

Step#1
Contact us
You're not sure if you need chimney services, or what to expect if you do. It's normal to have a lot of questions about chimney services- after all, it's not a service that most people need on a regular basis. That's why we offer free estimates and consultations so that you can get all your questions answered before moving forward with any work. We understand that your satisfaction is our number one priority, which is why we work hard to provide quality chimney services that meet your needs and expectations. We want to make the process as easy as possible for you, from start to finish!
Step#2
Proposal
You have a problem that needs to be fixed but you're not sure how or where to start. It can be tough to know where to start when it comes to fixing a problem, especially if you're not familiar with the topic. We're here to help. We'll do a full evaluation of what needs done and how it can be accomplished. We'll give you our proposal including plans, timelines for completion as well as the guarantee that if any issues arise during this process we have an answer or solution at hand!
Step#3
Construction
It's stressful to have people in and out of your house all the time. And it's even more stressful when you're not sure what they're doing or when they're going to be done.  It's hard enough keeping your sanity with construction going on day and night, but then to have to worry about the clean-up crew coming? Ugh. We take care of everything for you so that you can relax and enjoy your new space without any stress. You don't have to lift a finger except to tell us what you want. We'll work around your schedule, do all the dirty work, and leave your home just as clean (or cleaner) than when we found it.
