Every fire leaves behind soot, ash, and a sticky residue called creosote inside your flue. Over time, those layers restrict airflow and — if thick enough — can catch fire at temperatures that damage your chimney or spread to your home. Our technicians use industry-grade rotary brushes, powerful HEPA-filtered vacuums, and careful drop cloths so your living room stays spotless. We remove all combustion deposits from the firebox, smoke chamber, damper, and full flue liner. First-time homeowners are often surprised to learn how quickly deposits accumulate — even one cord of wood per season builds up. After our cleaning, you'll have better drafts, fewer odors, and genuine peace of mind every time you light a fire in Hopkinton this winter.

Andrew & Sons performs all three NFPA 211 inspection levels. Level 1 is a thorough visual check of accessible components — ideal for routine annual visits. Level 2, our most popular for new homeowners, includes high-definition camera scanning of the entire flue interior so we can spot cracks, blockages, or deteriorated liner sections invisible to the naked eye. Level 3 covers concealed areas when structural concerns arise. Every inspection produces a written summary with photos, so you can make informed decisions — and share clear documentation with your insurance company or real estate attorney if needed.
Request this service →The liner inside your flue is the barrier between extremely hot gases and the wood framing of your home. Clay tile liners in older Hopkinton houses can crack from heat cycling or freeze-thaw damage common to Massachusetts winters. Prefab metal liners in newer homes can corrode or separate at seams. Andrew & Sons installs stainless-steel flexible liners and rigid liners sized precisely for your heating appliance, ensuring correct draft and safe venting. We also repair cracked clay tile systems using high-temperature resurfacing compounds approved for residential use. A properly fitted liner improves combustion efficiency, reduces odor, and can extend the life of your entire chimney system by decades. We provide a written warranty on all liner installations.
Request this service →The chimney crown is the concrete or mortar slab that seals the top of your masonry chimney around the flue tile. When it cracks — and Massachusetts freeze-thaw cycles make cracking almost inevitable over time — water seeps in, accelerating deterioration of the liner, damper, and firebox. A chimney cap sits on top of the crown and covers the flue opening, blocking rain, snow, sparring embers, and nesting animals like squirrels and starlings (both common in Hopkinton's wooded neighborhoods). Andrew & Sons replaces missing or corroded caps with stainless-steel or copper models and resurfaces damaged crowns with elastomeric sealants designed for exterior masonry. These are among the most cost-effective preventive repairs we offer — often a few hundred dollars versus thousands in interior water damage repair later.
Request this service →The firebox — the chamber where your fire actually burns — takes an incredible amount of thermal stress. Repeated heating and cooling causes mortar joints to crack and bricks to spall. When those gaps open up, heat and combustion gases can reach adjacent wood framing, which is a serious fire hazard. New Hopkinton homeowners often notice blackened or crumbling mortar and assume it's just cosmetic wear. It rarely is. Andrew & Sons rebuilds damaged firebox walls using high-temperature refractory mortar and replacement fire brick that match the original dimensions. We also repair or replace the smoke shelf and throat damper, which control draft and prevent backdrafting. All firebox repair work is inspected after completion to confirm the restored area meets current safety standards before you light your first fire.
Request this service →Most homeowners focus entirely on the fireplace and forget about the dryer vent — until the dryer stops working efficiently or, worse, a fire starts. Lint buildup inside dryer vent ducts is one of the leading causes of residential fires in Massachusetts. Signs of trouble include clothes taking two cycles to dry, the dryer running hot to the touch, or a burning smell during operation. Andrew & Sons cleans dryer vents from the exterior termination point back to the machine, removing compacted lint and checking for crushed or improperly routed duct sections that restrict airflow. We also verify the exterior vent cover opens and closes freely to keep pests out. Many Hopkinton homeowners add dryer vent cleaning to their annual chimney appointment for a convenient, cost-effective safety check.
