Cleaning The Ducts

Smoke Damage And You

Make sure when dealing with smoke damage you do not use, under any possible circumstances, water-based cleaner on any plaster walls in the location where the smoke or fire damage occured. It would cause your walls to bleed and create more damage than you needed. It will bleed into the wall and ruin it further than it is. Use the correct type of cleaner so what you are doing will actually help in the process.

When a fire occurs, smoke can go into the walls and other types of surfaces and will drift through the ducts in your house, and it will get trapped. If you don't remove it properly, you will smell those smoke odors from time to time in the future, whenever the vents are at the wrong spot or have the air going through it. This will especially happen during warm or dampish times.
