Cast In Place Process -  The Supaflu System - STEP BY STEP

1. The Clean Sweep reline team arrives to the work site at the scheduled time.


2. The fireplace opening is sealed off and drop cloths are in place to prevent any debris from entering the room.


3. The existing clay flue tiles are removed from the chimney to make room for the new system.


4. All openings and or weak areas in the chimney structure are braced and reinforced before the former in installed.


5. The Supaformer, an inflatable rubber former, is lowered and guided into the clean chimney flue.


6. All necessary equipment and materials are strategically placed where needed to prepare for the pumping process.


7. The Supaformer is then inflated and centered within the flue with the use of spacers. The chimney in this picture will have three new flues.


8. The area around the damper plate is also sealed off to prevent mix from falling into the firebox.


9. The Supaflu mix is prepared on site and is pumped between the Supaformer and inside of the chimney wall.


10. After the mix has set, the former is deflated and pulled out, leaving a smooth, round highly efficient and safe flue passage.


11. A new crown is poured at the top of the chimney to seal out water.

(This step varies depending on your estimate and agreement of work to be completed)


12. A new chimney cap may be installed to prevent water or animals from entering the system.

(This step varies depending on your estimate and agreement of work to be completed)


13. Depending on the condition of the back wall one or all three walls will be rebuilt.

(This step varies depending on your estimate and agreement of work to be completed)



Stainless Steel Flexible Liner - STEP BY STEP


1. The Clean Sweep crew places drop cloths around the area where the work will be performed. 


2. The necessary tools and equipment are set up and ready to go. 


3. We begin by pressure washing the chimney to prep it for waterproofing at the end of the process. 


4. The entire chimney is pressure washed. 


5. The new stainless steel liner brought up to the roof for placement.  


6. The crew carefully lowers the new liner down into the chimney. 


7. Here you can see where the liner stops at the smoke chamber towards the bottom of the chimney. 


8. A member of the team places insulation around the pipe to hold the insulation mix in place. 


9. Here you can see the insulation in place and two chimney brushes with rods holding everything in place. 


10. From the top of the chimney a crew member pours Supaflu Mix down to the other end of the pipe to "set" the pipe in place.  


11. Here you can see another picture of the technician now pouring insulation around the stainless steel liner. 


12. A crew member climbs into the firebox and begins the process of using high heat resistant refractory cement to parge the smoke chamber. 


13. More parging. 


14. A view of the finished parged smoke chamber. 


14. Next the crown wash at the top of the chimney is skillfully crafted to keep future moisture / rain from entering the system.  


15. Here is an image of the final crown wash pour. 


16. Any dust or debris is washed off the roof. 


17. The chimney is then waterproofed using a brick sealant to keep out moisture. 


18. Finally, the work area is washed clean.
