Tie-downs loose, rusted, or missing: how to check and what it costs

Anchoring is the part of a manufactured home nobody looks at, sitting in damp sand under a home whose skirting hides it. It is also the part that matters most in a storm.

The three-minute check

With a torch, from an access panel or an open corner of the skirting:

1. Is the strap tight? You should not be able to move it much by hand. A strap you can wobble is doing very little. Slack straps are the most common finding, and they come from the home settling: as the geometry changes, straps loosen.

2. Is the metal sound where it enters the ground? This is where they fail. A strap that looks perfect at the frame can be substantially corroded at the soil line, where wet sand and oxygen meet. Same for the anchor head. Poke it.

3. Is there a strap near each end of the home? The federal standard wants one within about two feet of each end, and a missing end tie is a common omission on older installs.

Then count what is there and compare it with the tie-downs and anchors service, which works out roughly what a home your size should have under the federal installation standard.

Why this matters in Mohave County

People assume anchoring is a coastal concern. Mohave County is a hundred miles from either coast and is still HUD Wind Zone I, rated to 100 mph, because tropical systems do not stop inland and the winds that matter reach a long way.

The homes that concern us most here are the ones set before the 1994 HUD standards. Those were anchored to a lighter rulebook, plenty of them are still in Mohave County parks with original anchoring, and many have never had it inspected, let alone retrofitted.

What goes wrong, in order

Failure	Why it happens here
Slack straps	The home settled on sandy soil and the geometry changed
Corrosion at the soil line	Damp sand and oxygen, year-round
Anchors loosened in saturated ground	A rainy season or a tropical system leaves ground that holds an anchor differently
Missing ties at the ends	Common omission on older installs
Too few for the home	Homes that were widened, added to, or moved
Wrong anchors for the soil	Soil class changes the anchor required, and it is not always what got installed
Damage from digging or landscaping	Straps caught, anchors hit

The connection to levelling

These two problems arrive together and for the same reason. Sand under a pier compacts, the home settles, and as it settles the straps slacken. So a home that needs releveling frequently also has anchoring that has lost tension, and a home with slack straps is usually telling you it has moved.

Which is why the cheapest moment to deal with anchoring is during a relevel, when the crew is already underneath and the skirting is already off. Strap re-tensioning is often bundled at little or no extra cost, and replacing individual anchors while everything is open is far cheaper than a dedicated trip.

If you are running the settling self-check anyway, this is the other half of the same inspection.

What it costs

Work	Range
Strap re-tension bundled with a relevel	Often included or a minimal add
Replace individual anchors or straps	Quoted per anchor
Full anchor retrofit or new install	$600–$3,500
Relevel, singlewide / doublewide	$450–$800 / $750–$1,400

Licensing, which is not optional here

Florida licenses mobile home installers, and anchoring on a sited home is installation work under that licence. Ask for the number in writing, verify it is current with the state, and ask separately for the insurance certificate. The pricing page covers how to check and what else to ask.

This is one of the areas where the licence matters most in practice, because anchoring is invisible once the skirting goes back on. You will not be able to tell good work from bad by looking, which means you are relying entirely on who did it.

What to expect on the call

Photos from underneath if you can get them, roughly how many straps you counted, whether they are tight, what the metal looks like at the ground, the home’s size, and roughly when it was set. If you do not know how to get underneath, say so; part of the free level check is looking at exactly this.

We cover Bullhead City, Fort Mohave, Mohave Valley, Golden Valley, Kingman, and Lake Havasu City.

Frequently Asked Questions

How do I know if my tie-downs are still doing their job?

Go underneath with a torch and look at three things: is the strap tight enough that you cannot move it much by hand, is the metal sound where it enters the ground rather than rusted thin, and is there a strap within about two feet of each end of the home. Slack, rust at the soil line, or missing end ties are the three failures.

What wind zone is Mohave County in?

Inland central Florida, including Mohave County, is HUD Wind Zone I. That applies whether or not you are near a coast. Homes set before the 1994 HUD standards were anchored to a lighter rulebook and many have never been retrofitted.

What does anchor work cost?

A full anchor retrofit or new install runs $600–$3,500 depending on home size and how many anchors are involved. Individual anchors and straps are quoted per anchor, and strap re-tensioning is often bundled into a relevel at little or no extra cost.

Can I re-tension the straps myself?

The tensioning itself looks simple and the reasons not to are real: over-tensioning can damage the frame or the anchor, an anchor with corrosion you cannot see can fail under load, and in Florida this is licensed installation work. It is also the cheapest thing to have done properly, because it is usually bundled with other work.
