Frequently Asked Questions
-
Yes. AHT carries comprehensive general liability coverage, and a certificate of insurance is available on request. Certificates are sent directly to your office or your compliance contact.
-
Certain structural modifications or major rebuilds may require review or approval depending on site requirements or equipment specifications. We communicate with clients to ensure compliance when permit and spec documentation is necessary.
-
Typically. AHT—Mobile Welding & Fabrication is a field-based operation specializing in on-site equipment repair and reinforcement. However, we complete component or part procurement and prep in a private company shop.
-
We service the majority of Northern California. Our service range is coordinated at the time of scheduling to ensure timely mobilization. The About page carries the full service-area map and county list.
-
For larger or scheduled projects, a deposit may be required prior to mobilization and material procurement. Deposit requirements are outlined clearly in the proposal and service agreement to ensure transparency and project readiness.
-
Response time depends on current workload and project complexity. We prioritize critical structural failures and make every effort to mobilize promptly when operational downtime is involved. Priority response scheduling is available.
