Storm Gray Chimney Corp provides licensed, insured chimney sweep services in Andover, MN, specializing in pre-winter cleanings, inspections, and repairs for homes built in the 1970s–2000s along Andover’s tree-lined streets like Bunker Hills Golf Course neighborhoods and the newer developments off Rum River Drive. We’re your local experts ready to keep your chimney safe before the first Anoka County freeze hits.
Why Andover homeowners should schedule a chimney sweep before October
In Andover, the first hard frost often arrives by mid-October, and that’s when homeowners start firing up fireplaces and wood stoves for the season. A neglected chimney can trap creosote—a tar-like byproduct of burning wood—up to ¼ inch thick by spring, which the ((National Fire Protection Association (NFPA)|https://www.nfpa.org/)) warns is a leading cause of chimney fires. Storm Gray Chimney Corp recommends scheduling your Andover chimney sweep between late August and early October, before the Rum River area’s humidity spikes and before the Anoka County winter maintenance rush. We’ve serviced homes on Bunker Hills Parkway and the newer subdivisions off U.S. Highway 10, where many fireplaces see their first use of the season around Halloween. Waiting until November risks longer wait times and higher call volumes as neighbors realize their chimneys need attention. Learn more about Storm Gray Chimney Corp home page.
Creosote buildup in Andover chimneys: what it is and why it’s dangerous
Creosote is a black, tarry residue that coats the inside of your chimney every time you burn wood. In Andover’s older homes—especially those built in the 1980s with masonry chimneys—creosote can accumulate faster due to the area’s higher humidity from nearby lakes like George Watch Lake. The ((Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) classifies creosote into three stages, with Stage 3 being a glaze-like coating that ignites at just 451°F. Even a thin layer can reduce chimney draft, sending smoke and carbon monoxide back into your Andover home. Our team uses rotary brushes and HEPA vacuums to remove every trace, ensuring your chimney meets NFPA 211 standards before the first Anoka County freeze. See our full list of services.
How Andover’s weather affects chimney performance and safety
Andover’s climate swings from humid summers to subzero winters, with wind gusts up to 30 mph along the Rum River corridor. These conditions stress chimney masonry, especially in homes built before 2000 when mortar joints weren’t always reinforced with modern additives. Ice dams in winter can also push water into cracks, accelerating deterioration. Storm Gray Chimney Corp checks for freeze-thaw damage during every Andover chimney inspection, focusing on chimneys venting fireplaces in the Bunker Hills neighborhood where many homes have two-story masonry stacks. We seal cracks with high-temperature mortar and recommend chimney caps to block wind-driven rain—critical for homes near the Rum River’s floodplain. Explore request a free estimate / contact us.
What to expect during your Andover chimney sweep appointment
When our team arrives at your Andover home—whether it’s a 1970s rambler on Bunker Hills Parkway or a newer build off U.S. Highway 10—we start with a Level 1 inspection per CSIA guidelines. We’ll check the flue, smoke chamber, and damper, then use rotary brushes sized for your chimney’s dimensions (many Andover homes have 8-inch flues). Expect the process to take 60–90 minutes, depending on creosote thickness and chimney height. We’ll also test for draft issues, which are common in Andover’s older homes where chimneys may have settled over time. After cleaning, we provide a free estimate for any repairs needed to meet local building codes. For details, see about our team and credentials.
How often should Andover homeowners schedule chimney maintenance?
The ((Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends sweeping your chimney when creosote reaches ⅛ inch or more, but Andover’s climate and wood-burning habits often require more frequent attention. Homes with wood stoves or older masonry chimneys should schedule a sweep every 1–2 years, especially if you burn softwoods like pine, which produce more creosote. Newer homes in Andover’s subdivisions off U.S. Highway 10 may only need a sweep every 3 years if using seasoned hardwoods. We tailor our recommendations based on your chimney’s usage and the type of wood burned—critical for homes near the Rum River where humidity can accelerate residue buildup.
Cost of chimney sweeping in Andover, MN: what to budget
In Andover, chimney sweeping costs typically range from $120 to $250, depending on chimney height, flue type, and creosote level. A standard single-flue masonry chimney (common in homes built in the 1980s–1990s) averages $150–$180, while taller chimneys or those with heavy creosote buildup may cost up to $250. Storm Gray Chimney Corp offers free estimates, and we’ll provide a detailed breakdown before work begins. For Andover homeowners bundling services—like a pre-winter inspection with a cap repair—we offer discounts. Ask about our loyalty program for repeat customers in neighborhoods like Bunker Hills or the newer developments off U.S. Highway 10.
Can you use your fireplace immediately after a chimney sweep in Andover?
Yes, you can safely use your fireplace the same day after a professional chimney sweep in Andover. Our team ensures all creosote and debris are removed, and we’ll test the draft to confirm proper ventilation. However, if we identify cracks in the flue liner or other issues during the inspection, we’ll recommend repairs before use. For homes in Andover’s older neighborhoods—like those near Bunker Hills Golf Course—we often find minor masonry repairs needed after years of neglect. We’ll provide a free estimate for any work required to get your chimney up to code before the first Anoka County freeze.
How Andover’s housing stock impacts chimney needs
Andover’s homes span from 1970s split-levels on Bunker Hills Parkway to newer luxury builds off U.S. Highway 10, and each presents unique chimney challenges. Older masonry chimneys in the 1970s–1990s homes often lack modern liners, making them prone to cracks and creosote buildup. Newer homes may have stainless steel liners but can suffer from poor draft due to nearby trees or wind patterns along the Rum River. Storm Gray Chimney Corp specializes in diagnosing these issues, whether it’s a chimney cap needed for a Rum River-area home or a liner replacement for a Bunker Hills fireplace. We tailor our solutions to Andover’s diverse housing stock, ensuring safety and efficiency year-round.

Frequently Asked Questions
How much does a chimney sweep cost in Andover compared to Ramsey or Coon Rapids?
In Andover, a standard chimney sweep averages $150–$180, slightly higher than Ramsey ($130–$160) due to Andover’s older housing stock and longer travel times from our Anoka base. Coon Rapids tends to be more competitive ($120–$150) because of higher service density. Storm Gray Chimney Corp offers free estimates and discounts for bundling services, such as inspections with minor repairs.
When is the best time to schedule a chimney inspection in Andover before winter?
Schedule your Andover chimney inspection between late August and early October, before the first hard frost and the Anoka County winter rush. Homes near Bunker Hills Golf Course or off U.S. Highway 10 often see their first fireplace use around Halloween, so getting ahead of the curve ensures you’re not waiting weeks for an appointment.
Do Andover homes with wood stoves need more frequent chimney maintenance?
Yes. Wood stoves in Andover homes—especially those in newer subdivisions off U.S. Highway 10—produce more creosote than fireplaces and should be swept annually. The EPA's Burn Wise program recommends using seasoned hardwoods and scheduling a sweep every 1–2 years for wood stoves, even if you don’t use them daily.
What’s the difference between a Level 1 and Level 2 chimney inspection for Andover homeowners?
A Level 1 inspection is the standard for routine maintenance in Andover, covering the flue, smoke chamber, and accessible portions of the chimney. A Level 2 inspection is required if you’ve had a chimney fire, purchased a new home, or made structural changes—common for older homes in Bunker Hills or Rum River-area properties. Storm Gray Chimney Corp performs Level 1 inspections during every sweep and recommends Level 2 if we find significant damage.
