What to Expect After You Contact Us
We've made the process of getting from first contact to job complete as simple as possible. Here's what happens from the moment you reach out.
You Call or Submit the Form
For emergencies, calling is always faster — we pick up immediately and can dispatch a crew while you're still on the phone. For non-emergency estimates and project consultations, the form works perfectly. Include as much detail as you can about the property, the situation, and your timeline — it helps us prepare before we call you back.
We Call You Back Within 15 Minutes
A member of our team — not an answering service, not a scheduler, someone who actually knows the work — calls you back within 15 minutes of receiving your form submission. We ask a few questions, get a clear picture of what you're dealing with, and determine the right next step: immediate dispatch, a site visit for an estimate, or a phone consultation for a larger project.
We Come to the Property
For emergency calls, a crew is dispatched immediately. For estimates and inspections, we schedule a site visit at your convenience — typically available same day or next day for most of our Long Island service area. We arrive on time. We walk the property thoroughly. We don't give you a price from the driveway.
You Receive a Clear Written Estimate
For planned projects and non-emergency work, we provide a written, itemized estimate that spells out exactly what the project includes, what it costs, and what the timeline looks like. No vague line items, no verbal commitments. For insurance claims, we prepare scope-of-work documentation formatted specifically for adjuster review — which is different from a standard contractor estimate and which matters significantly for claim outcomes.
Work Begins — With a Named Point of Contact
Once you're ready to proceed, work is scheduled and a named project manager or superintendent is assigned to your job. You'll have their direct contact information. You won't be chasing someone down through a general office number when you have a question or when something comes up mid-project. That accountability is not an extra — it's how we operate on every job.
