Many Eagan homeowners assume their chimney is fine until we show them the creosote buildup or rusted components. We’d rather you see it now than after a fire or CO scare.
Our work speaks for itself. After sweeping an Eagan home with heavy creosote, one client told us, ‘We’ve burned wood for 20 years, and this is the first time we’ve felt truly safe.’ That’s why we do this work. Not for awards, but because a clean chimney means a home that’s protected, not just from soot, but from the silent killers like carbon monoxide.
We hold ourselves to the highest standards so you can hire with total confidence.

Hernandez and John Chimney Co. has been keeping Eagan homes safe for decades by focusing on one thing: preventing fires before they start. We don’t just clean chimneys, we inspect them for hidden dangers like cracked flues, blocked drafts, and creosote buildup that most sweeps miss. In a city where winter fires spike after heavy snowfall, our team treats every chimney like it’s our own, because it is. We follow Minnesota’s strict chimney safety codes and use tools that detect carbon monoxide leaks others can’t, giving you peace of mind when you light that first fire of the season.
Give us a call at (612) 425-0268, and we’ll schedule a no-obligation inspection. We’ll ask about your chimney’s age, what you burn, and any issues you’ve noticed, like smoke smell or slow drafts. If you’re in Eagan, we’ll often fit you in same-day for urgent concerns like blocked vents or gas odors.
Our crew brings rotary brushes, vacuum systems, and leak detectors to every job. For Eagan’s older homes, we might use a borescope camera to check flue conditions without tearing into walls. We’ll also bring a ladder rated for your chimney height, no shortcuts, just thorough work.
We sweep your chimney, then inspect for creosote, cracks, or blockages. If we find problems, we’ll point them out and give you options. No upselling, just honest advice. For example, if your Eagan home’s chimney has a rusted damper, we’ll tell you it needs replacing before it fails mid-winter.
After the work, we’ll walk you through what we did and what to watch for. If we repaired anything, we’ll show you the fixes. Then we’ll clean up, no mess left behind. Your chimney will be safer, and you’ll know exactly why. That’s how we roll in Eagan.
"We’ve burned wood for years, but after our first sweep with Hernandez and John, we finally understood why our chimney smelled like gas sometimes. They found a cracked liner and sealed it, now our fireplace works perfectly, and we sleep better knowing there’s no hidden danger. Worth every penny."
"Our chimney had so much creosote, the sweep said it was a ‘ticking time bomb.’ They cleaned it out in one visit and showed us photos of the buildup. Now we sweep twice a year, and our home inspector never flags our chimney anymore. Professional, fast, and they actually care about safety."
"We moved into an older Eagan home and were terrified of using the fireplace. The first thing we did was call Hernandez and John. They found a blocked cap and a rusted damper, both of which could’ve caused a fire. Fixed in one day, and they explained everything so we knew what to do next time."
"After a chimney sweep in another town left soot everywhere, we swore off DIY. Hernandez and John were the opposite, they vacuumed every bit of debris and even cleaned our ceiling fans. Their crew was polite, thorough, and took the time to answer all our questions about Eagan’s chimney codes."
"We had no idea our chimney was leaking until they pointed it out. They waterproofed the crown and said it would save us thousands in future repairs. Now we don’t have to worry about ice dams or water stains in the ceiling. Best investment we’ve made in our Eagan home."
"I’ve had chimneys swept before, but no one ever checked for carbon monoxide like these guys did. They tested our gas lines and said our old venting was a risk. We upgraded, and now we’re protected. That’s the kind of service that makes you want to recommend them to every Eagan neighbor."

Expert local advice for Eagan homeowners.
Yes, that’s a serious red flag for carbon monoxide risk. The smell usually means unburned gas is leaking into your home, often from a blocked flue or cracked liner. We’ve seen this in older Eagan homes with neglected chimneys, especially after heavy snow packs the flue shut. Never ignore it, turn off the fireplace immediately, open windows, and call us for an emergency inspection. We’ll check for blockages, test for CO leaks, and clear the chimney safely before you use it again.
Creosote is the thick, flammable tar left when wood doesn’t burn completely, a major fire risk. In Eagan’s dry winters, it can build up faster than you think. Look for a shiny, glass-like coating inside your chimney (Stage 2 creosote) or hard, brick-like chunks (Stage 3). If you see soot blowing into your living room or a strong smoke smell when lighting the fire, that’s another sign. We use high-powered vacuums and brushes to remove it safely, no scraping tools that could damage your flue.
Absolutely. Minnesota’s water is notoriously hard, and Eagan’s supply is no exception. Over time, minerals in the water can corrode metal components, weaken mortar joints, and even cause rust in the damper. We’ve seen chimneys in older Eagan homes fail prematurely because of this. If your chimney has white crusty deposits or rust stains, it’s time for a full inspection. We’ll check for water damage, seal leaks, and recommend repairs before small issues become big ones.
Yes, especially if you’ve used your fireplace regularly. Creosote buildup accelerates with frequent use, and Eagan’s dry air means it dries out faster, becoming more flammable. Even if it looks clean, hidden layers can form. We recommend sweeps at least once a year for gas fireplaces and twice for wood-burning ones. If you’ve had any repairs or changes to your chimney, we’ll inspect those too, no assumptions, just safety.
Minnesota requires chimneys to meet strict safety codes, and Eagan enforces them. If your chimney fails an inspection, like having a cracked liner or improper clearance from combustible materials, you’ll need repairs before you can use it. We’ve helped homeowners avoid fines by catching issues early, like missing chimney caps or improperly installed stovepipes. We’ll check your setup against local codes and give you a clear plan to stay compliant.
Even brand-new homes need sweeps. Modern chimneys can still develop creosote, especially if the fireplace isn’t venting properly. We’ve inspected high-end Eagan developments where draft issues went unnoticed until it was too late. Plus, if your home has a gas fireplace, the venting system needs checking for corrosion or blockages. Don’t skip it, just because it’s new doesn’t mean it’s safe.
Only if we confirm it’s safe to use afterward. If we find heavy creosote or structural issues, we’ll let you know exactly when it’s safe. Otherwise, a quick burn test confirms everything’s clear. Pro tip: After sweeping, burn only dry, seasoned wood and keep the fire hot to prevent new creosote buildup. We’ll show you how to maintain it properly so your next sweep goes faster.
Draft problems usually come from blockages, cracks, or poor chimney design. In Eagan, snow and ice can pack into the flue, or a damaged liner might be restricting airflow. We’ve fixed draft issues by clearing obstructions, sealing leaks, or even adjusting the damper. If your fire smolders instead of roaring, that’s your chimney telling you something’s wrong. We’ll diagnose the exact problem and fix it so your fireplace works like it should.
