This primarily depends upon the length of time it takes and the size of the job. The reason this is so difficult to “estimate” up front is due to it being a task of “discovery”. This means until we have mapped the affected areas out and removed the damaged materials, we cannot guess how much it will cost to mitigate. Remember, if the damaged area is covered under your property insurance policy, this task will be covered as well. Most times you will only be responsible for your deductible.
