Call (661) 219-7906

This page is for Santa Clarita homeowners who already own a Mighty Buildings home or ADU and need to expand it. If you’re adding square footage to a Mighty Buildings structure, the integration details matter more than with a traditional stick-built house. Call (661) 219-7906 and Troy Eastman will walk through exactly what that looks like on your property.

How Mighty Buildings Products Fail – and How We Fix Them

Mighty Buildings builds with prefabricated composite panels, which changes how additions tie in. Here’s what we see on real job sites in Santa Clarita:

• Panel joint separation at the roofline. The Mighty House series uses factory-cast panels that meet at engineered seams. In Santa Clarita’s dry heat, thermal expansion and contraction works those seams harder than coastal climates. We see hairline gaps open at the eave line, especially on south-facing elevations. The fix is re-flashing and re-sealing the joint with a flexible sealant rated for our 100°F summers, then re-securing the connection points to the original panel anchors.
• Mismatched foundation interfaces. Mighty Buildings panels sit on a pre-engineered base. When a site-built addition is poured against that base without accounting for the existing panel system’s load path, you get differential settling. We see this on bump-out additions where a concrete stem wall was poured tight against the Mighty foundation. Our crews spec a proper expansion joint and tie the new footing to the existing base per the original structural plans.
• Panel face delamination near moisture sources. On bathroom additions tied into Mighty Homes, we’ve found panel faces softening where plumbing runs behind the wall without proper moisture barriers. The composite material doesn’t fail the way drywall does, but it does delaminate if water sits against it. We open the wall, assess the panel integrity, and install proper waterproofing before closing it back up.
• MEP chases that don’t align. Mighty Buildings runs electrical and plumbing through factory-formed chases in the panels. On garage additions, we regularly find that the original chase locations don’t line up with where the new space needs power and water. Fixing that means routing new runs through pathway spaces that respect the panel engineering without drilling blind through structural members.
• Roof tie-in leaks on additions. Connecting a new roof to the existing Mighty panel roof is the number one leak source we correct. The original roofing system is designed to move as a single unit; adding a section creates a hinge point. We’ve had to re-flash and re-seam more than a few Canyon Country additions where water crept in at the transition line.

Our Mighty Buildings Home Addition Contractor Process

1. 1
   Site walk and measurements. We come out, measure the existing Mighty Buildings structure, document how the panels are set, and map where the addition will tie in. Troy Eastman personally reviews the tie-in points, because this is where Mighty Buildings additions succeed or fail.
2. 2
   Written price before work starts. You get a line-item quote covering design, structural work, materials, labor, and permits. Not a verbal range. A written number. No surprises at the door, no scope creep billed after the fact.
3. 3
   Permit drawings and submittal. We handle the plans and the permit package. Santa Clarita has specific requirements for additions to prefab structures, and we’ve worked with enough of them to know what the plan checker looks for.
4. 4
   Construction and tie-in work. Our background-checked, uniformed crew builds the addition, ties it into the Mighty building envelope correctly, and documents progress with photos so you can see exactly what happened every step of the way.
5. 5
   Inspection and walkthrough. We stay on site through inspections, then walk the finished space with you. You get a digital invoice and a written guarantee before we consider the job done.
6. 6
   365-Day Done Right Promise. If anything on our work fails within a year, we come back and fix it. That’s in writing, stamped on every project. If a covered repair fails again, you get a free second visit.

Why Santa Clarita Homeowners Call Benson ADU Santa Clarita for Mighty Buildings Work

Mighty Buildings is one of the prefab brands we build with, and that’s the honest answer to why people call us. We’re not a general contractor who glanced at a Mighty Buildings brochure once. We work with Abodu, Cover, Dvele, Boxabl, Plant Prefab, and Tuff Shed too, so when you need an addition tied into your Mighty Home, we understand how the panel system actually behaves versus how it looks in marketing photos.

More importantly, you get The Relay Visibility Guarantee on every project. That means a written price before work starts, a 365-Day Done Right Promise, a written guarantee on every project, and a free second visit if any covered repair fails. And when you call us at midnight with a question about your project timeline, a live person answers. Not a voicemail loop. Not an answering service that promises a callback Tuesday. Someone who can actually help.

As Troy Eastman puts it: “Price it in writing, build it right, no surprises – that’s the whole job.”
