A Clean Chimney Is A Safe Chimney!  
Stay Safe With A Chimney Clean By DNA's!

No homeowner should assume his or her chimney is safe for use without a thorough examination, both exterior and interior. Rain, flue gases, and freezing moisture cause erosion and deterioration in chimneys. Breaks in the chimney liner - even small ones - can be an unsafe condition by allowing combustion gases and condensation into the home.

In the past, the examination of the chimney interior involved either a flashlight and mirror or the expensive disassembly of part of the chimney to see problem areas. Now with our video inspection service, we can obtain an accurate evaluation of your chimney's interior. As your chimney inspector, we will be able to show you these unsafe chimney conditions, if they exist: · Improper new construction · Chimney fire damage · Improper prefab chimney connections · Deterioration from gas appliance connections · Cracks, even hairline cracks, in flue liners · Broken or missing tile liners and mortar joints · Deterioration from smoke shelf or damper · "Quick-fixed" thimble holes · Hidden breechings · Nest, limbs and other blockages
