Request Service

Independent service-request website. We are not a contractor. Requests may be shared with a third-party provider; the provider confirms scope, pricing, and availability.

A technical signal a qualified provider should be able to speak to on this scope: the federal model-installation reference in 24 CFR § 3285.6 uses no more than a ¼-inch level difference between adjacent pier supports, plus exterior doors and windows that operate without binding, as leveling checks.

What the mating line is

The mating line, often called the marriage line, is where two or more sections of a multi-section home join. Multi-section homes add section connections and mating-line supports that a single-section home does not have in the same way, so the seam is its own area of evaluation with its own possible causes when something changes.

Which decision this page answers

This page is for the multi-section connection and mating-line decision. If the concern is a support component anywhere on the home, that is the pier and support repair page. If the perimeter enclosure is what changed, that is the skirting repair page. For the whole-home elevation decision, start from the main leveling guide.

The honest split

Alignment and mating-line support work is one job. Connection hardware, seam sealing, gasket work, roof-seam work, and finish repair can be separate jobs. The same visible seam change can come from support movement, from the condition of the connections, or from the finish materials themselves, so the provider must distinguish the cause and the written scope must say which of these is included. That is the core of getting a marriage line repair right.

Safety

Do not go under the home. Observe from a safe exterior position.

Observable conditions and what to note

Use these headings to organize what you can see safely. They are for your notes, not for diagnosing the cause yourself; separating the causes is the provider's job on site.

Mating-line conditions an owner can observe safely
What the owner sees	What a qualified provider should distinguish	Why it matters	What to note before calling
A gap or crack near the center seam	Whether the change comes from support movement, connection condition, or finish materials	The same visible change can have different underlying causes	Roughly where along the seam and how long the affected run is
A ridge or lip in the floor at the seam	Whether the two sections have shifted in elevation relative to each other	A floor ridge along the mating line points to alignment or support along that line	Which rooms the ridge runs through and whether it changed recently
Light, air, or pests coming through the seam	Whether the opening is a support gap, a connection gap, or a failed seal	The remedy differs for a support gap versus a finish or gasket gap	Where you notice light or drafts and in what weather
Ceiling seam cracking that keeps returning	Whether movement continues or the crack is only cosmetic recurrence	Returning cracking can indicate an ongoing support or connection condition	When it was last repaired and whether it reopened in the same place
A sudden change at the seam	Whether an event moved a support or a connection let go	Sudden and gradual changes suggest different evaluations	When you first noticed it and whether anything preceded it
A gradual change at the seam	Whether slow support settlement or seasonal movement is at work	Gradual change may tie back to soil or footing conditions along the line	How long you have watched it change and by roughly how much

The federal leveling yardstick

The federal model-installation reference is a level comparison, not a horizontal spacing figure. Under 24 CFR § 3285.6, the checks are no more than a ¼-inch level difference between adjacent pier supports, plus exterior doors and windows that operate without binding. This page does not publish mating-line pier spacing, a lag-bolt interval, or a connector count, and it gives no sealing, gasket, foam, drywall, or connector installation instructions; those belong to the provider working from the manufacturer instructions and the standard.

Scope and exclusions

Under Texas definitions, mating-line supports are part of the support system, while the perimeter enclosure and stabilizing anchors are separate categories. A marriage line scope should name whether it covers alignment and mating-line support, connection hardware, sealing or gasket work, or finish repair, and it should not be read as including skirting, anchors, or roof and finish work unless those words appear in the terms.

Licensing and documentation

Leveling and foundation-component work is installer work in Texas. Ask the provider for the TDHCA license number and check it in the public license-holder search. Where the work is licensed re-leveling, ask for the Notice of Installation, Form T, and the written installation warranty afterward.

Texas fee and inspection notes

Where the work is reportable re-leveling, the state reporting fee is $75 for a single-section home plus $25 for each additional section, submitted with Form T. The state inspection program gives priority to multi-section homes and Wind Zone II counties, which includes many Coastal Bend addresses.

Process and what a written scope should separate

A clear scope keeps the pieces apart: alignment and mating-line support on one line; connection hardware on another; sealing, gasket, or roof-seam work separately; and any finish repair on its own. When each piece is written down, a finish-only price cannot be mistaken for support or connection work.

Cost drivers

This page lists drivers, not a Corpus Christi price. What changes a marriage line scope includes the configuration and number of sections, the length of seam affected, the condition of the supports along the mating line, access and clearance, whether connection or finish work is included, and any related repairs.

Limitations

This site does not diagnose the cause of a seam change or specify hardware, spacing, or sealing methods. It organizes the request and the questions to ask; the provider confirms scope, pricing, and availability on site.

What to have ready

Have the home configuration and number of sections, safe exterior photos and interior photos of the seam that concern you, a note of which rooms the seam runs through, whether the change was sudden or gradual, and any records of prior work along the seam.

How the request and confirmation work

You describe the home and what you are seeing; the request may be shared with a third-party provider; the provider confirms coverage, capability, scheduling, pricing, exclusions, and terms directly with you before any work is arranged.

Frequently asked questions

Why is my double-wide separating at the seam?

A change at the center seam can come from support movement beneath the mating line, from the condition of the section connections, or from the finish materials that cover the seam. The same visible separation can have any of these causes, which is why a qualified provider has to distinguish them on site and the written scope has to say which cause is being addressed. This site cannot tell you which one it is from the outside.

Is marriage line repair the same as leveling?

They overlap but are not the same. Alignment and mating-line support work is one job; connection hardware, seam sealing, gaskets, roof-seam work, and finish repair can be separate jobs. A leveling number should not be read as covering the connection or finish work along the seam unless those words appear in the written terms, so ask for the scope to be split into the pieces that actually apply.

Will fixing the drywall crack solve it?

Finish repair addresses the appearance of the seam, not a support or connection condition beneath it. If the underlying cause is support movement or a connection that has loosened, patching the drywall can leave the crack to return. That is why the provider should distinguish the cause first and the written scope should say whether any support or connection work is included alongside the finish repair.

What changes marriage line repair pricing?

Cost drivers include the configuration and number of sections, the length of seam affected, the condition of the supports along the mating line, access and clearance, whether connection or finish work is included, and any related repairs. Where the work is reportable re-leveling, the state reporting fee is $75 for a single-section home plus $25 for each additional section. This page lists drivers only and does not publish a Corpus Christi price.
