Derick Wiley — owner & lead estimator.
A company that has a solution to every problem — with a vetted bench of crews ready to respond to your needs, backed by a modern estimating automation platform. Every estimate is built and reviewed by the owner, every job is walked, and every call is answered.
Derick has spent 26 years in the restoration and general- contracting industry, with substantial experience writing scope and estimates for residential and commercial property losses. He held general-contractor licenses in Mississippi and Florida earlier in his career, and today holds IICRC Water Damage Restoration Technician certification, ICC certification, the Missouri DHSS Lead Renovator (RRP) license, and Xactimate Level 2. He's the only person who writes Wiley Services estimates — built in Xactimate, the same system most carriers use for internal estimating. He has 22 years operating Xactimate, with working knowledge of other estimating software.
“The automation platform gets the scope right. My job is to verify every line and make sure the homeowner gets what they actually need.”
A family business with one boots-on-the-ground operator.
Derick's wife handles overflow calls when the line is busy and is the family's escalation path — if Derick is in a dead zone, she'll keep the job moving. Their daughter contributes graphic design and IT support.
Day-to-day estimating, dispatch, scope documentation, and site supervision all sit with Derick. When you call Wiley Services, the call goes to the owner or a family member on the team.
