Before You Call Helitech Waterproofing & Foundation Repair

1. Do you take moisture readings every day and will you give me the drying log?
2. Are your technicians certified in water damage restoration?
3. How will you deal with smoke odor inside wall cavities and the HVAC ducts?
4. Do you do contents pack out, and will I get an itemized inventory?
5. Is your firm certified under the federal lead renovation rule?

Missouri has no statewide general contractor license, so check with your city or county, and in Illinois ask a roofer for a state roofing license. Also ask for proof of insurance and industry certification for the restoration crew.
