TLS Laboratories is available to help homeowners resolve difficult water intrusion problems. We recreate the problem leak using a methodically applied water spray. The methods used by our field experts will allow us to identify the source (or the sources) of the leak. Once we know the source (or the sources) of the water intrusion, we may prescribe a course of action that will stop the leak from continuing.

Our testing experts photodocument our testing and actually photograph the leak as it occurs. This is useful if insurance reimbursement is possible, or for documenting who may be responsible for a leak. If arranged for in advance, video will be taken of the testing process; professionally created DVDs may be produced that demonstrate any leaks discovered.

After the testing is completed, a professionally prepared report is generated that accurately describes the leaks discovered; opinions are given that describe what is necessary to mitigate the problems. Fees for our services vary upon where the home is located. TLS Laboratories has traveled both nationally and internationally to assist homeowners with leak problems. Testing fees are usually based upon a daily rate plus travel expenses and fees.
