Assessment & Estimation

The first step in repairing a damaged or wrecked semi-trailer is to assess the extent of the damage and provide an estimate for the cost of repairs. This may involve inspecting the frame, sidewalls, roof, flooring, and other components to identify any damage that needs to be repaired.

Disassembly

Once the assessment is complete and the estimate is approved by the customer, the next step is to disassemble the trailer. This may involve removing damaged components, cutting away damaged sections of the frame or sidewalls, and preparing the trailer for repair.

Repair & Replacement

After disassembly, the damaged components will need to be repaired or replaced. This may involve welding new sections onto the frame or sidewalls, replacing damaged or missing components, or reinforcing weak areas to prevent future damage.

Reassembly

After the repairs and refinishing are complete, the trailer will be reassembled and tested to ensure that all components are working properly.

Quality Control & Delivery

The final step is to perform a quality control check to ensure that the trailer is safe and meets all relevant standards. Once the trailer is deemed safe and ready to go, it can be delivered to the customer.

Our Testimonials

What Our Customers Say

“Very happy with the work by Ryan and his team. Ryan is easy going and easy to communicate with. He did our pool and yard remodel under some fairly strict budget and timing constraints, both of which he met. We just returned from two weeks in Hawaii and we were very happy to come back to our own little resort.”
Cathy J.Orange, CA
“This company is a great find. Ryan is a very knowledgeable guy. We hired him to do our hot tub. He did a great job. Showed up every day and on time! We later hired him to build us an outdoor kitchen and bar. Came out beyond what we expected. Prices are fair. He has the perfect temperament for this line of work. Always calm and ready to solve anything that comes up. Awesome!”
Plate W.Newport Beach, CA
“We have a home built in 1928 and the mortar between the bricks has been deteriorating along with water seeping in under the foundation of the office by the brick wall. Ryan came in and fixed the leakage problem along with bringing our brick work back to beautiful condition.”
Pam S.Orange, CA
“Around The Castle did a renovation project for our front yard. The project was designed by landscape architect Patrick May. The project included hardscape, landscaping, demo, trees, a courtyard reno and fountain. ATC did a fantastic job bringing the design to life. Ryan and his crew stayed in line with their original estimate and met all schedule commitments throughout. We are completely satisfied with the way the project turned out and the overall experience working with ATC. Highly recommend ATC.”
Chris T.CA
“I am a Preschool Director and was looking to create a safer wall environment for our play yards. Ryan came in with great ideas to add onto some of our exsisting walls/gates. Ryan and his crew were so easy to work with. Very professional, walked me through each part of the project. It turned out better than I imagined. If I could give more stars I would.”
Julie G.San Francisco, CA
Ryan and his team at Around the Castle are literally the best contractors we have ever worked with. They gave us our dream backyard. Around the Castle delivered a perfect detailed backyard.

Our very large detailed project (front, back and side yard) was completed within a couple weeks of the target time, which we were very pleased about. The end results of our beautiful landscape are well worth the time and money invested. There was very good communication with the client. Highly skilled Masons, as well as trustworthy employees.

"We recently hired 'Around the Castle' to handle both the front and backyard hardscaping and landscaping, including an addition to our backyard. Of the five contractors we considered, Ryan Moat and his team stood out with their detailed and precise bid. The quality of work delivered by 'Around the Castle' was exceptional, which is evident as all our friends and family keep asking who did the work! We couldn't be more pleased with the outcome and highly recommend Ryan and his team for any landscaping needs."

Frequently Asked Questions

Deciding to move forward on repairing, rebuilding, or replacing your trailer?  Making the right decision is not always an easy decision. It is only right that you have questions before starting a project. Here are some common questions that we receive, if you don’t find your answer here, please give us a call and we can set up a consultation to make sure all your questions and concerns are addressed.

A rebuild, restoration, or overhaul of a transport trailer is a comprehensive process that addresses structural, mechanical, and electrical issues to extend its service life. The complexity and cost of rebuilding versus replacing a trailer depend on the extent of the damage.

A complete rebuild is typically considered when the trailer's frame is still in good condition, but major components are worn out, outdated, or heavily damaged. The following are common reasons to rebuild: 
  • Cost-effectiveness: If repairs exceed 50% of the trailer's current value, replacing it is often the more sensible option. Otherwise, a rebuild can be a more affordable choice to keep a reliable unit in service.
  • Extensive component failure: When major systems like the suspension, axles, and brakes all require significant repairs, a comprehensive rebuild is more efficient than a series of smaller repairs.
  • Structural issues: Rebuilding is the solution for significant structural damage, such as frame cracks, damaged cross-members, or degraded decking.
  • Corrosion and age: For older trailers showing widespread rust and corrosion, a complete overhaul—including sandblasting and repainting—can restore the unit and add many years of service.
  • Modernization: Rebuilding allows for upgrades to modern, more efficient components, such as updating the electrical system, brakes, and hydraulics on a heavy-haul trailer. 
The process will vary depending on the trailer type and condition, but generally follows these steps: 
  1. Damage assessment and teardown: A thorough inspection is performed to identify all damaged components. The trailer is then disassembled to its frame.
  2. Structural repair: The frame is the foundation of the trailer. Cracked welds are repaired, and bent or rusted frame members are fixed or replaced, often through welding.
  3. Rust and corrosion treatment: The frame is sandblasted or stripped to bare metal to remove all rust. A rust-resistant primer and paint are then applied to the metal surfaces.
  4. Component repair and replacement: Key systems are addressed, including:
    • Axles and suspension: Axles are inspected for damage, wheel bearings are repacked or replaced, and the suspension (springs, hangers, bushings) is serviced.
    • Brake system: Brake shoes, drums, air lines, and slack adjusters are inspected and replaced as needed.
    • Electrical system: All wiring, lighting, and ABS connections are replaced or repaired to ensure they meet modern safety standards.
    • Deck and flooring: Damaged or rotted wood decking is replaced to restore a secure hauling surface.
  5. Reassembly and finishing: The repaired components are reassembled. The trailer is then painted and tested to ensure all systems are functioning properly.

The timeline for a rebuild depends on the severity of the damage, the complexity of the trailer, and the availability of parts. While some minor restorations have been completed in a matter of weeks, extensive projects can take months to complete, especially if custom work is require
