It is generally not safe to live in a house with smoke damage, as even minor damage can pose long-term health hazards and structural risks. While it might seem safe temporarily depending on the severity, you should relocate if there is major damage or visible soot. Smoke smells and residue contain dangerous particulates and chemical compounds, including carcinogens, that are hazardous to breathe and can cause respiratory issues. These signs of damage are not always visible but can have dangerous short-term and long-term effects on your health, belongings, and your home's structural materials. You should not stay in the house until a trained professional from a smoke remediation or restoration company has assessed the damage and determined it is safe to return. Your insurance company may cover the cost of alternative housing while the professional work is completed.

Smoke damage will not go away on its own, but with professional remediation and restoration, you can return your home to its original condition after a fire. Trained smoke restoration professionals can eliminate smoke damage, which can affect areas of your home that are hard to see or access, and restore or replace smoke-damaged materials.

Luckily, you can typically eliminate your microwave’s burnt smell within a few hours for most situations. Be sure to let it air out for two to three hours after cleaning to let the odor evacuate your home—if you close your home up too early, the odor will be trapped. For stronger, more stubborn burnt smells, it might take a full day or more to really notice a difference. 

The timeline for fire damage restoration varies significantly, from a day or two to over a year, depending on the extent of the damage. For minor incidents like a small cooking fire, cleaning up soot and removing smoke odors may only take a day or two. Repairing minor damage might take about one to two weeks. However, a major fire requiring structural repairs, full property renovation, and replacement of materials can take anywhere from six to 12 months to over a year. This longer timeline often includes waiting for insurance approvals and contractor scheduling. It's best to consult with your insurance provider and restoration team to get an accurate timeline for your specific situation.
