A top-rated chimney sweep in Longmont, CO, holds CSIA certification, carries full insurance, provides clear pricing, and offers free estimates. Look for transparent inspections, local reviews, and warranties on work. Daniel Thompson Chimney Inc. meets all these standards and serves Boulder, Longmont, and nearby areas.
1. Is the chimney sweep CSIA-certified and insured?
A CSIA-certified chimney sweep in Longmont, CO, has completed rigorous training on chimney systems, fire codes, and safety standards set by the Chimney Safety Institute of America CSIA. This certification ensures your sweep knows how to spot hazards like creosote buildup, cracked flues, or improper clearances—especially important in older Boulder-area homes near the Flatirons where chimneys often endure heavy snow loads and temperature swings. Always ask for proof of certification and insurance. A reputable pro will show you their card and provide a copy of their liability and workers’ compensation coverage. Without insurance, you risk being liable if an accident happens on your property. Daniel Thompson Chimney Inc. posts our CSIA credentials and insurance certificates on our about page for easy verification.
2. Does the sweep offer free estimates and transparent pricing?
A trustworthy chimney sweep in Longmont, CO, will walk you through the inspection process and give you a written estimate before starting work. At Daniel Thompson Chimney Inc., we provide free, no-obligation estimates for all services, including chimney sweeping, inspections, and repairs. We explain what we’ll check—from flue condition to chimney cap function—and why. Hidden fees or vague quotes are red flags. If a pro pressures you to sign on the spot or won’t itemize costs, walk away. Transparency matters, especially in competitive markets like Longmont, where homeowners near Ken Pratt Boulevard or in the historic district need clarity before hiring. Our pricing guide is available on the pricing page so you can compare before you call.
3. Can they perform a Level 2 inspection during the sweep?
A chimney inspection is a thorough visual examination of your flue, liner, smoke chamber, and exterior. The Chimney Safety Institute of America CSIA defines three levels of inspection. A Level 2 inspection includes a video scan of the flue and is recommended after any chimney fire, when you change fuel types, or before buying a home. In Longmont, where many homes were built in the 1970s and ’80s, hidden damage from past earthquakes or shifting foundations is common. A top-rated sweep will offer Level 2 inspections and explain why it’s worth the small extra cost. Daniel Thompson Chimney Inc. includes Level 2 video inspections with every sweep appointment—just ask when you book.
4. Do they clean and inspect chimneys year-round in Longmont?
A reliable chimney sweep in Longmont, CO, doesn’t just show up in fall. We service homes in Longmont, Niwot, and Erie all year, including after heavy snow seasons when ice dams or roof loads can stress chimneys. Waiting until October to book a sweep risks long wait times and rushed service. Boulder County’s dry climate and altitude mean creosote builds up faster than in lower elevations. We recommend scheduling your first sweep within 30 days of moving into a Longmont home—even if the previous owners said it was clean. Our team keeps a flexible schedule and offers emergency inspections after windstorms or chimney fires. Book online or call our team to check availability.
5. Do they explain local building codes and chimney caps?
Longmont follows the International Residential Code (IRC) and local amendments, which require chimney caps, proper clearances, and spark arrestors. A knowledgeable sweep will point out code violations like missing caps, rusted dampers, or unlined flues—especially in older neighborhoods like the Longmont Historic District or near Main Street. We also install and repair chimney caps to keep out rain, birds, and embers. A missing cap can lead to water damage, which is costly to repair in Boulder’s freeze-thaw climate. Daniel Thompson Chimney Inc. offers free cap consultations and installs durable stainless steel caps backed by a 5-year warranty.

6. Will they provide a warranty on labor and parts?
A top-rated chimney sweep stands behind their work. At Daniel Thompson Chimney Inc., we offer a 1-year labor warranty on all chimney sweeping and repair services. If we install a new liner or repair a crown, we back it with a manufacturer’s warranty. Always ask for a written warranty before work begins—verbal promises aren’t enough. This is especially important in Longmont, where older masonry chimneys often need crown repairs after decades of exposure. We also recommend scheduling a follow-up inspection before the warranty expires to catch any new issues early. Our services page lists all warranties and guarantees.
7. Do they have strong local reviews and service history?
Look for a chimney sweep in Longmont, CO, with consistent 5-star reviews on Google and Angi, and ask for references from neighbors. Daniel Thompson Chimney Inc. has served Boulder County since 1998, with hundreds of local reviews praising our punctuality, cleanliness, and clear communication. We’ve worked on homes from the Victorian houses on 4th Avenue to modern builds in Prospect New Town. A sweep with deep local roots understands Longmont’s unique challenges—like the impact of altitude on creosote formation or the need for extra clearance near power lines on South Main Street.

Frequently Asked Questions
My new Longmont home has a brick chimney that’s never been swept. Where do I even start?
Start with a Level 2 inspection and sweep. Even if the previous owners said it was clean, Colorado’s dry air and altitude speed up creosote buildup. A CSIA-certified sweep will check for cracks, blockages, and proper drafting. Book a free estimate with us today here.
Why does my Boulder-area fireplace glass stay so dirty after just one burn?
Dirty glass is usually caused by burning wet wood, poor airflow, or a dirty flue. In Boulder’s high-altitude climate, wood doesn’t burn as hot, leading to more soot. A professional sweep can clean the flue and recommend a glass cleaner safe for your stove. Try our guide How to Clean Fireplace Glass Doors Without Scratching Them (Boulder Homeowners’ Guide).
Is it safe to use my Longmont fireplace after a chimney fire scare last winter?
No. After any chimney fire, you must have a Level 2 inspection before using the fireplace again. Even a small fire can weaken the flue liner or crack the chimney crown. Schedule an inspection with a CSIA-certified sweep immediately. Learn more in our guide Boulder Chimney Inspections: Types, Costs, and Why They’re Critical for Your Home.
How much should a chimney sweep cost in Longmont, CO, and what’s included?
