A fireplace should feel easy. It should light fast. It should draft clean. It should not smoke into the room or smell like soot. Our chimney sweep service keeps it that way. Ductech protects your home. We sweep from top to hearth. We keep dust contained. We share photos and plain notes. We offer same-day service when possible. Our work includes a clear service warranty. Parts we install are original-spec and include a parts warranty. Our method is eco-friendly and low-odor.
Soot builds with every burn. Creosote can harden into shiny glaze. That buildup restricts draft. It can ignite. Smoke may spill at start-up. Odors can linger for days. Moisture and acids can harm mortar and metal. A thorough sweep removes the fuel that should not be there. Draft improves. Fires start easier. Glass stays clearer. Your living room stays clean.
We brush the main flue. We clean the smoke chamber. We vacuum the smoke shelf. We tidy the firebox area we open. We free sticky or rusty dampers. We clear the cap screen when accessible. We remove light nesting and debris. We capture everything with HEPA filtration. No dusty clouds. No mess on rugs or sofas. We wipe the hearth and reset screens or doors.
We look for cracked tiles and missing mortar. We note any glaze, not just soft soot. We check prefab liners for warping or corrosion. We review crowns for hairline splits. We look at flashing for leak tracks. We inspect cap and spark screen condition. We test damper travel and seal. We verify draft with a quick live check. You get photos and clear, plain advice.
White Oaks hearths often sit under tight chases. Howard Park and El Sereno layouts can hide elbows near the roofline. San Carlos Hills homes feel wind shifts and use roof caps. Downtown condos may limit workspace around stacked units. We plan for each layout. We bring the right rods and brushes. We protect landscaping and finishes. Kids at home? We stage noisy steps. Pets around? We keep paths secure. We leave the area neat.
Use seasoned hardwood. Keep it split and dry. Warm the flue with kindling at start-up. Open the damper fully. Add larger logs once draft is strong. Never burn trash or treated wood. Store ash in a metal can with a lid. Keep décor and rugs clear of the opening. Test smoke and CO alarms monthly. Small habits prevent big problems.

Pricing you approve first
Chimneys differ. Height, roof pitch, access, and buildup change the job. We explain the scope. We give a clear quote. You approve before we start. If we discover a new issue mid-visit, we pause, show photos, and discuss choices. No surprise add-ons.
We serve the entire City of San Carlos: 94070 (standard delivery) and 94071 (San Carlos P.O. Box/unique).
Dryer vents collect lint quickly. Elbows trap fibers. Exterior flaps stick. Heat builds. Cycles drag. Sensors trip. A clear vent restores airflow and cuts run time. Our dryer vent cleaning clears the lint-trap cavity, the transition connector, the full in-wall run, and the outside hood or roof cap. We set floor protection and contain dust with HEPA equipment. We free stuck dampers and confirm full travel during a live test. If parts are crushed or outdated, we install UL-2158A semi-rigid connectors, proper clamps, and a code-compliant hood. All parts are original-spec and include a parts warranty. Most homes benefit once a year. High-use homes or long roof runs may need every 6–9 months. Many San Carlos clients pair dryer vent service with a chimney sweep for a complete safety reset in one visit. Learn more here.
Your HVAC touches every room. Dust and pollen settle in supply and return runs. Airflow drops. Rooms feel uneven. Cleaning the ducts resets comfort and reduces dust on surfaces. We set negative pressure, brush and vacuum trunks and branches, and wipe grilles. We tidy accessible plenums. We capture debris with HEPA gear. We avoid harsh chemicals by default. On request, we can apply a low-odor, eco-friendly sanitizer. Most homes do well every 2–3 years. With pets or allergies, plan 18–24 months. Booking air duct cleaning with your sweep is common before the cool season. One appointment. Fresh airflow through the house. Full details are here.
How long does a sweep take?
Most visits take 45–90 minutes. Steep roofs, heavy buildup, or tight access can add time. We confirm the window on arrival.
Do you need to go on the roof?
Sometimes. If the cap is safe to reach, we may go up. If not, we work from below. We choose the safest, cleanest method for your home.
Do you clean gas fireplaces and inserts?
Yes. Gas creates soot and haze over time. We clean the flue path where applicable, tidy the firebox area we open, and check draft and damper function.
Will there be a mess?
No. We stage floor protection, seal the opening as needed, and use HEPA capture. We wipe the hearth area and show before/after photos.
Do you use chemicals?
Not by default. We rely on mechanical sweeping and HEPA containment. If odor control is needed, we offer a low-odor, eco-friendly product.
How do I know it’s time again?
If glass blackens fast, smoke spills at start-up, or a soot smell appears with the damper open, it’s time. Frequent burning often needs 6–12 months between sweeps.
