A professional chimney inspection is a multi-step evaluation of your heating system that checks structural integrity, creosote buildup, and venting safety. In Andover, MN, technicians use specialized cameras and tools to examine every inch from the firebox to the rooftop, ensuring your home complies with local safety standards.
Level 1 Chimney Inspection: What a Standard Andover Chimney Sweep Checks First
A chimney inspection is a routine visual check of all readily accessible portions of your interior, exterior, and appliance connections. When you schedule a standard Andover chimney sweep, your technician starts right at the fireplace. We examine the firebox, damper assembly, smoke chamber, and the visible connector pipe if you have a wood stove or gas insert. We look for cracked refractory panels, warped dampers, and early signs of creosote glaze that ordinary sweeping brushes might not clear out on their own. Next, we step outside to look at the masonry exterior. We check the siding clearance, the base of the chimney, and the cleanout door in the basement or yard. According to guidelines set by the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)), any chimney that has not changed its fuel type or operating system requires at least this baseline check every single year. For homeowners in Andover, MN, heavy snow accumulation and ice dams can impact the lower exterior walls of a chimney chase. Catching small hairline cracks here before the freeze thaw cycle begins saves you from massive masonry repairs later.

Level 2 Chimney Inspection: Inside the Flue with Specialized Cameras
A chimney inspection is a detailed, camera-assisted diagnostic procedure required when buying or selling a home, after a suspected chimney fire, or following severe weather events. During a Level 2 assessment in Andover, our technician accesses the roof to examine the crown, flashing, cap, and brickwork up close. We then run a specialized high resolution camera down the entire length of the flue liner. This is where many hidden hazards come to light. Clay tile liners can crack from thermal shock during sub-zero Minnesota nights, allowing heat and carbon monoxide to leak into your wall framing. the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) outlines strict codes regarding clearance to combustibles, and our camera sweep ensures your flue meets every single requirement. We check for missing mortar joints, spalling bricks, and blockages from bird nests or debris. If you are preparing your fireplace for the heating season, review our how to prepare for your chimney appointment guide to ensure our technicians have clear access to both the roofline and the hearth. We also service neighboring communities, so if you have friends in the area, they can read about our work on our Ham Lake chimney services page. We cover this in our full list of services.
Level 3 Chimney Inspection: Destructive Checks for Hidden Damage
A chimney inspection is an invasive investigative procedure used only when serious hazards are suspected behind walls, ceilings, or masonry structures. While Level 1 and Level 2 checks cover almost all routine maintenance and real estate transactions, a Level 3 evaluation becomes necessary if a previous inspection reveals deep-seated structural flaws. This might involve removing sections of drywall, dismantling interior chase walls, or taking apart exterior brickwork to inspect the internal framing and chimney support system. In Andover homes, older masonry chimneys built decades ago sometimes suffer from shifting foundations due to heavy frost heave in the clay soil. If a chimney starts leaning or pulling away from the house frame, a basic visual sweep from the roof will not suffice. We have to look at the structural ties and footings underneath. For local homeowners who want to understand the warning signs before things reach this stage, our masonry repairs and repointing guide breaks down what to watch for. Whenever you notice unusual settling, cracks near the ceiling line where the chimney meets the drywall, or persistent smoke drafting issues, do not wait. Reach out to our crew through our contact page to schedule a thorough evaluation.
The Roof and Exterior Assessment: Crowns, Caps, and Flashing
A chimney inspection is a rigorous rooftop review of the crown, flashing, and cap designed to keep Minnesota rain, snow, and wildlife out of your flue. When our crew climbs up on an Andover roof, we check the metal flashing where the chimney pierces the roofline. Rusted or lifted flashing is the number one cause of water stains on upstairs ceilings after a heavy spring downpour or winter thaw. We also inspect the concrete or mortar chimney crown. A cracked crown acts like a sponge, soaking up water that freezes, expands, and shatters the masonry from the top down. Installing a sturdy stainless steel chimney cap prevents squirrels, raccoons, and leaves from turning your flue into a nesting ground. For more details on protecting your chimney top, check out our resource on chimney cap installation or learn about preventive waterproofing methods in our chimney crown waterproofing guide. If you operate a wood burning stove rather than a traditional open hearth, you can also browse our fireplace and stove cleaning guide for specific maintenance intervals that keep your unit burning clean and efficient all season long.
