How To Mend A Manufactured Home’S Marital Line?

This article provides steps to repair the marriage line in a manufactured home, focusing on identifying the problem and determining the extent of the repair needed. The first step is to inspect the marriage line for signs of damage, such as water stains, mold, or gaps. If the marriage lines in the ceilings cracked badly when the furnace first came on in fall 2005, it is essential to seal the gap with gasket material or spray foam.

In a mobile home, air seal the marriage joints between sections of a modular or manufactured home with gasket material or spray foam. Install a gasket along the marriage line. If replacing the subfloor and eliminating the marriage line may lead to future problems, it is recommended to use a quality floating laminate floor.

The marriage line is the seam where two sections of a manufactured home meet. Common remedies include re-constructing tilted and fallen-down piers, installing additional piers as needed, replacing single-stack piers with double-stack piers along the marriage line(s), replacing rotted wood pads with prefabricated (plastic) or concrete pads, and adding and removing shims to achieve level.

In a 2016 manufactured home in Northern CA, cracking in the ceiling at the marriage line is common, and a 2-3″ gap at the marriage line is not uncommon. The piers should be secured/sealed. If you are unsure about filling in the marriage line gap in the floor, you can cut the line back several inches on each side, put in a new drywall board, and then mud/tape, plus texture.
