Permit Filing & Tracking

We handle every step—from initial application to final inspection approval—working directly with city and county building departments.

Engineering Letters

We work closely with licensed Florida engineers to provide fast, accurate engineering letters for a wide range of projects, including:

- Sunroom and patio enclosures
- New window or door openings
- Altered structural openings

And other custom retrofit configurations These letters are tailored to your project and ensure a smooth permitting and inspection process.

- Contractor license documents
- Product approvals (Florida Product Approval Numbers or NOAs)
- Engineering drawings and site-specific structural details
- HOA compliance forms, if applicable

Product Approval Coordination

We ensure all windows and doors used in your project meet the Florida Building Code and, if applicable, HVHZstandards. We’ll verify product specs, model numbers, and installation methods before submittal.

Municipality Communication

We deal directly with the city or county building departments, responding to revision requests, uploading additional documentation, and ensuring your permit doesn’t get stuck in review.
