D&D Chimney Cleaning serves Portsmouth and surrounding New Hampshire communities with NADCA-certified Fireplace Repair that goes beyond surface cleaning. We don’t just vacuum your vents — we use commercial-grade equipment to create negative pressure throughout your entire duct system, dislodging contaminants that have built up over years of humid continental climate conditions. The result? Cleaner air, lower energy bills, and a healthier home for your Portsmouth family.

If any of these sound familiar, your Portsmouth home’s chimney flue is overdue for professional attention.
A common misconception among Portsmouth homeowners: “I change my filter regularly, so my ducts are clean.” The reality? Standard filters capture only 10-15% of airborne particles. The rest settles in your chimney flue — building up layer after layer with every HVAC cycle. In New Hampshire’s humid continental climate where heavy heating seasons and moisture adds constant new contaminants, your filter is fighting a losing battle without professional backup.
We’re not a franchise that cycled through Portsmouth last month. We serve New Hampshire communities consistently because our reputation depends on it. Every Portsmouth customer receives meticulous attention to detail, commercial-grade equipment, and an unconditional satisfaction guarantee. We photograph everything, explain everything, and stand behind everything — because that’s what Portsmouth families deserve.
