What Onyx handles
Experienced help for the work already on your schedule.
We have written estimates for contractors since 2017. Call us when a project has unusual details, your workload grows, or office tasks are taking time away from the job.
WHAT YOU SEND
Start with the information you already have
Measurements, photos, plans, notes, and project records are organized into one clear scope.
WHAT ONYX DOES
More estimating capacity without another desk hire
We turn field documentation into detailed estimates and stay available for questions and revisions.
BACK-OFFICE SUPPORT
More than an estimate
Need help with invoices or keeping jobs organized? We can take those back-office tasks off your plate, too.
Clearer estimates. Less deskwork. More room to focus on the job in front of you.

Practical answers
A clearer way to get estimating help.
We start with a conversation, learn how your team works, and agree on the scope before preparing a project estimate.
What kinds of estimates do you write in Xactimate?
We prepare contractor-requested estimates for roofing, siding, mitigation, rebuild, and related property work based on the project information you provide.
What should I send to get started?
Send the measurements, photos, notes, and project details you have. We will discuss what else is needed before quoting the work.
Who is responsible for the estimate?
The contractor who hires us must review and approve each estimate before using or submitting it. Check the scope, quantities, and pricing against actual site conditions and request corrections. Your company decides what to do with the estimate and is responsible for its bid, work, and submissions. Onyx does not control those decisions or guarantee their outcomes.
