How to Choose a Chimney Sweep: What to Ask and Red Flags to Watch

I’m Tim McGirl, owner of A&T Chimney Sweeps LLC in Northern Virginia. I’ve spent more than a decade cleaning and inspecting chimneys across Fairfax, Loudoun, Prince William, and the greater DC metro area. In that time, I’ve heard every horror story — homeowners scammed by fly-by-night operators, people who paid twice for the same job, and families who didn’t learn about serious hazards until it was almost too late.

In this guide, I’ll give you the exact questions I’d ask if I were hiring a chimney sweep — along with the red flags that should make you hang up the phone.

Why Choosing the Right Chimney Sweep Matters

Your chimney is one of the most critical safety systems in your home. It vents combustion gases — including carbon monoxide — out of your living space and contains intense heat within your walls. When it works, you never think about it. When it fails, the consequences range from smoke damage to house fires to carbon monoxide poisoning.

The NFPA reports that failure to clean chimneys is the leading cause of chimney fires, with over 25,000 occurring annually. A bad chimney sweep doesn’t just waste your money — they give you a false sense of security. You think your chimney is safe. Meanwhile, there’s a cracked flue liner or dangerous creosote buildup that nobody told you about because nobody looked.

10 Questions to Ask Before Hiring a Chimney Sweep

I’m going to give you the questions I think matter most — and I’ll tell you what the right answers sound like. If you’re calling around or filling out contact forms, keep this list handy.

1. How Long Have You Been in Business?

Experience matters. A sweep who’s been at it for a decade or more has seen every chimney configuration, fuel type, and problem you can imagine. They know what a hairline crack in a flue tile looks like versus normal wear. They can spot a problem in 30 seconds that a newer tech might miss entirely.

Longevity is a meaningful signal. A company that’s been serving the same area for 10+ years has had to earn repeat business and build a real reputation. At A&T Chimney Sweeps, we’ve been serving Northern Virginia homeowners for over a decade — that doesn’t happen by accident.

2. What’s Included in Your Service?

A lot of chimney companies get vague here on purpose. They’ll quote you a price for a “chimney sweep” but won’t define what that means until the upsell begins. A clear answer should include:

• Full cleaning of the flue from top to bottom (or bottom to top, depending on method)
• Cleaning of the smoke shelf and smoke chamber
• Removal of all soot, ash, and creosote
• An inspection (more on this in the next question)
• Cleanup of the work area

If the person on the phone can’t give you a straight answer about what’s included, that’s telling you something important about how they run their business.

3. Do You Include a Chimney Inspection?

This question separates professionals from everyone else. A sweep who just runs a brush through your flue and leaves is doing half the job. A proper visit should include an inspection of the structural and functional components of your chimney. There are three levels defined by the NFPA:

• Level 1: A visual examination of readily accessible portions of the chimney. This is the bare minimum.
• Level 2: Includes everything in Level 1 plus examination of accessible areas in attics, crawl spaces, and basements. Often includes video scanning of the flue interior. Recommended whenever you have a cleaning done, and required when buying or selling a home.
• Level 3: Involves removal of certain components (drywall, chimney crown, etc.) to investigate hidden hazards. Only done when serious problems are suspected.

Many companies charge separately for inspections — often $100 to $250 on top of the cleaning fee. That’s a legitimate business model, but it means your actual cost is much higher than the quoted sweep price. Ask specifically whether an inspection is included and what level it is.

4. What Are Your Prices? (No Surprises)

A reputable chimney sweep should give you a clear, firm price before they arrive. Not a “range.” Not an “it depends.” A number. For a standard cleaning and inspection, there should be a published price — ideally right on their website.

If a company won’t tell you what they charge until they’ve sent someone to your home, that’s a red flag. They’re setting the stage for an in-person upsell, and you’ll feel pressured because they’re already there.

Our pricing at A&T Chimney Sweeps is published right on our pricing page: $139 for a chimney cleaning that includes a Level 2 inspection. No hidden fees, no pressure, no surprises.

5. Can I See Your Reviews?

Every company says they do great work. Reviews verify it. Look on Google — not just the company website, where they can cherry-pick. When reading reviews, look for:

• Specific details — “He showed me photos of the creosote buildup” is more meaningful than “great job!”
• Mentions of professionalism — Did the tech show up on time? Were they clean? Did they explain what they found?
• Consistent patterns — A handful of five-star reviews might be from friends and family. Hundreds of consistent reviews tell a real story.
• How the company responds to criticism — Every business gets the occasional bad review. How they handle it matters.

We’re proud of our client reviews, and I encourage you to read them before you decide. But I’d tell you the same thing about any chimney company — always check the reviews.

6. Do You Clean Up After the Job?

Chimney cleaning is messy work. A professional should use drop cloths, a HEPA vacuum, and take every precaution to keep your home clean. When done, there should be zero evidence anyone was there — no soot on your carpet, no ash on your mantle, no boot prints on your floor. If they seem surprised by this question, that tells you something.

7. What Equipment Do You Use?

Professional chimney sweeps use rotary cleaning systems, industrial HEPA vacuums, video camera inspection systems, moisture meters, and proper containment materials. You don’t need to become an expert, but asking this question tells you whether the company invests in doing the job right. A sweep who shows up with a single brush and a shop vac isn’t equipped for thorough work.

8. Will You Explain What You Find?

The homeowner deserves to understand the condition of their chimney. Not a vague “looks fine” or a scary “you need $3,000 in repairs.” A real explanation — ideally with photos or video — of what was found, what it means, and what needs attention.

A good chimney sweep is also an educator. They should explain how creosote forms, why your damper matters, and whether that crack is cosmetic or structural. If a sweep finishes in 20 minutes and can’t tell you anything about your chimney’s condition, they either didn’t look or don’t know what they’re looking at.

9. Do You Offer Other Services? (Combos, Dryer Vents)

A full-service chimney company typically offers dryer vent cleaning, chimney cap installation, crown repair, waterproofing, and masonry work. This matters for convenience — if you can get your chimney and dryer vent cleaned in one visit, you save time and money. We offer a chimney and dryer vent combo for $239.

It’s also a sign of expertise. A company with broader capabilities can spot issues that cross service lines — your chimney problems might relate to your roof, masonry, or ventilation. Our dryer vent cleaning is $119, and we recommend it annually — clogged dryer vents are a leading cause of house fires.

10. Can I Schedule Online?

A chimney sweep with online scheduling has invested in systems and processes. They’re organized and respect your time. It also means you can book at your convenience — 10pm on a Tuesday when you finally remember — instead of trying to catch someone during business hours.

Red Flags When Hiring a Chimney Sweep

After more than a decade in this business, I’ve seen every trick. Here are the warning signs that should make you walk away.

Door-to-Door Solicitation

Legitimate chimney companies build their business through reputation, referrals, and marketing — not by cold-knocking neighborhoods. Door-to-door chimney “inspectors” frequently offer a cheap or free inspection, “discover” a dangerous problem, and pressure you into expensive repairs on the spot.

I’ve had customers call me in a panic because a door-knocker told them their chimney was about to collapse. When I got there, it was fine. Rule of thumb: if you didn’t contact them, don’t let them on your roof or in your home.

No Fixed Pricing

If a company won’t tell you what a standard cleaning costs before they arrive, something is wrong. Companies that avoid quoting prices upfront are often planning to upsell once they’re in your home. You’re less likely to say no when someone is standing in your living room.

Scare Tactics and High-Pressure Sales

A professional will tell you the truth — good or bad — without using fear to pressure you into immediate repairs. If someone says your chimney is “an emergency” and you need to pay right now before getting a second opinion, that’s manipulation. Genuine chimney emergencies are rare, and a trustworthy professional will encourage second opinions on major repairs.

Cash Only, No Receipts

Any legitimate business accepts standard payment methods and provides receipts. If someone insists on cash and doesn’t offer documentation of the work performed, you have no recourse if something goes wrong. You also have no proof of service for insurance purposes or for a home sale.

No Inspection Included

A chimney sweep who cleans without inspecting is like a dentist who polishes your teeth but never checks for cavities. The whole point of having a professional in your home is to identify safety hazards and maintenance needs — not just to remove soot. If the company doesn’t include any form of inspection, you’re paying for a superficial service that could leave real problems undetected.

Unbelievably Low Prices

A chimney cleaning for $49 or $59 should raise immediate questions. Professional chimney sweeping requires expensive equipment, trained technicians, and vehicle costs. A price that low means corners are being cut, or it’s bait-and-switch to get a foot in your door before the upselling starts.

What a Good Chimney Sweep Visit Looks Like

Here’s what a quality chimney sweep appointment should look like from start to finish.

Before the Visit

• You received a clear price quote on the website or over the phone
• You scheduled at a time that works for you
• You got a confirmation with the expected arrival window

When the Technician Arrives

• They arrive on time (or call ahead if running late)
• They put down drop cloths and set up containment around the fireplace
• They wear clean shoe covers or remove their shoes

During the Service

• Thorough flue cleaning with professional-grade equipment and HEPA vacuum
• Visual and/or camera inspection of the flue, smoke chamber, damper, firebox, cap, and crown
• Photos or video of any concerns

After the Service

• Clear walkthrough of findings — with photos or video if applicable
• Fair pricing on any recommended repairs — no pressure
• Complete cleanup: your home should look exactly as it did before
• Receipt provided, total matches the quoted price

That’s the standard we hold ourselves to at A&T Chimney Sweeps, and it’s the standard you should hold every chimney service company to. Anything less, and you’re not getting what you’re paying for.

How Much Should a Chimney Sweep Cost?

Here’s what you should expect to pay in 2026. For a deeper dive, see our Virginia chimney sweep cost guide.

Our $139 chimney cleaning is below the typical fair range — and includes a Level 2 inspection that most companies charge $100–$250 extra for. View our full pricing and service details here.

Why A&T Chimney Sweeps Includes a Level 2 Inspection with Every Cleaning

Most chimney companies charge $100 to $250 for a Level 2 inspection on top of their cleaning fee — meaning a cleaning plus inspection runs $250 to $450. A Level 2 goes beyond the basic visual check: it includes video scanning of the flue interior, examination of accessible areas in attics and basements, and a thorough evaluation of structural integrity. The NFPA recommends this level whenever a chimney is cleaned.

We include the Level 2 inspection with every chimney cleaning — all for $139. Cleaning without inspecting is like changing your oil but never checking your engine. I’d rather find a cracked flue liner during a routine cleaning and give you a fair quote to fix it than have you find out during a chimney fire. That’s not a sales pitch — that’s how I’d want my own chimney taken care of.

Frequently Asked Questions

How do I know if a chimney sweep is legitimate?

Look for established businesses with a real website, years of service in your area, consistent online reviews, and transparent pricing. A legitimate sweep answers questions openly and never pressures you into immediate decisions. Check Google reviews for patterns of detailed, positive feedback.

How often should I have my chimney cleaned?

The NFPA recommends annual inspections, with cleaning as needed. If you burn wood regularly, annual cleaning is almost always necessary. Gas fireplaces need less frequent cleaning but should still be inspected yearly. Learn more in our chimney cleaning guide.

What’s the difference between a Level 1 and Level 2 chimney inspection?

Level 1 is a basic visual check. Level 2 includes video scanning of the flue interior and examination of accessible areas like attics and basements — recommended with every cleaning and required when buying or selling a home. See our chimney inspection guide for details.

Can I clean my chimney myself?

You can attempt it, but I don’t recommend it. Without training, you’ll likely miss creosote in the smoke chamber and smoke shelf — major fire hazards. You also can’t inspect the flue interior or identify structural problems. At $139 with an included Level 2 inspection, professional cleaning is affordable enough that the risk-reward math doesn’t favor DIY.

What time of year is best to schedule a chimney sweep?

Spring and summer are best — lower demand means more flexibility, and you’ll be ready before heating season. October and November are the worst times to call, when everyone remembers their chimney and availability gets tight.

How long does a chimney cleaning take?

Typically 45 minutes to an hour for a standard single-flue chimney. Multiple flues, heavy buildup, or additional services like dryer vent cleaning may take longer. The technician should give you an estimated timeframe before starting.

Should I be home during the chimney cleaning?

Yes. The technician needs access to your fireplace and may need access to your attic or basement for the inspection. Being home also lets you see the before-and-after condition, ask questions, and get a firsthand explanation of findings.

What should I do to prepare for a chimney sweep visit?

Clear the area around your fireplace — move furniture and mantle items at least three feet back. Remove the grate and leftover ash if possible. Ensure a clear path from your front door to the fireplace, and mention any roof access issues in advance.

Is a chimney sweep worth the cost?

Absolutely. A cleaning costs $139–$200, while a chimney fire can cause $10,000–$50,000+ in damage. Annual maintenance is one of the most cost-effective home safety investments you can make — especially when that cleaning includes a Level 2 inspection that costs $100–$250 elsewhere.
