What we promise

Three things that don’t change
from one job to the next.

01

90-minute response.
Twenty-four seven.

When your basement floods at 2 a.m., you don’t get a callback in the morning. We’re there in ninety minutes or less. Trucks pre-staged with extraction and drying equipment. Real ETA texts, not “between one and five.”

  • Live phone, not voicemail
  • Pre-staged extraction + drying trucks
  • Crew dispatched the moment you hang up

02

We test before
we tear out.

Unless the damage is visible and obvious, we test first. Air-quality readings. Surface samples. Moisture mapping. Then a written scope built from that data, not from a hunch. The honest version: sometimes the test tells us less needs to come out than you feared. That’s the test doing its job.

  • Air-quality + surface testing in-house
  • Written scope before any demo begins
  • We tell you what you don’t need to remediate

03

Insurance that
goes through
the first time.

We write the file your carrier wants, Xactimate-aligned scope, photos, line items, drying logs, moisture readings, equipment counts. No back-and-forth. No kicked-back claims. Stressful enough already; the insurance side shouldn’t add to it.

  • Xactimate-aligned scope and pricing
  • Photo + drying-log documentation built in
  • Direct adjuster communication when you authorize it

The Gateway team

How a job runs

Four steps.
Same every job.

  1. 01

    You call. We answer.

    Live phone, twenty-four seven, not voicemail. We confirm the situation, dispatch a crew, and tell you what to do (and not do) until we get there.

  2. 02

    On-site in 90 minutes.

    Uniformed crew, clean truck, equipment ready. Drop cloths down before we touch anything. Photo documentation starts the moment we arrive.

  3. 03

    We test, then plan.

    Moisture readings. Air-quality + surface samples where appropriate. Written scope-of-work that explains what we’re doing, why, and what we’re not doing.

  4. 04

    Clean handoff to your insurance.

    Xactimate-aligned scope. Drying logs. Photo documentation. Adjuster communication when you authorize it. Your claim goes through the first time.

  • Xactimate-aligned scope and pricing
  • Photo + drying-log documentation built into every job
  • Direct adjuster communication when you authorize it
