Winterization Services

Winterization services for vacant houses, rentals, and buildings that will not be heated.

A winterization drains and protects a property's water system so a freeze does not burst a pipe in a building nobody is watching: supply lines drained, antifreeze in traps and fixtures, the water heater and boiler handled by type, and every system tagged and photographed. Ethreon performs dry, wet/steam, and radiant winterizations on vacant houses, rental property between tenants, REO and servicer-held property, and commercial buildings, then re-winterizes after inspections and de-winterizes when the property reopens.

Scheduled before the required window opens — September 1 in Ohio and Pennsylvania, October 1 in Texas, Louisiana, Alabama, Arkansas, and Oklahoma under the HUD and USDA schedules — and verified at every inspection through the end of it.

Freeze Protection

Three methods, one standard of proof.

Which winterization a property needs depends on its heating system. A dry winterization drains the domestic water supply, blows the lines, and treats the traps; a wet or steam winterization adds the hot-water heating system; a radiant winterization handles in-floor or baseboard hydronic loops. Each is priced separately by every investor program, and each leaves a different set of tags and photos behind.

The Southern states are where winterizations get skipped and freezes get expensive. A property in Texas or Louisiana rarely sees a hard freeze, which is why the one that comes finds an unwinterized house. Ethreon winterizes to the calendar, not the forecast, and documents the work so the servicer's claim or the owner's insurance file has the proof.

Winterization Scenarios

Property we winterize.

A vacant building is a vacant building whether a servicer, a landlord, or a facility manager holds it; the method follows the heating system and the documentation follows the client.

Vacant Houses and Rentals Between Tenants

A rental that will sit empty through a cold snap, an inherited house, a listing that has not sold — winterized before the window opens so the owner is not paying for a burst pipe in a house they are not living in.

REO, Foreclosed, and Servicer-Held Property

Dry, wet, and radiant winterizations to the investor's specification and allowable, with tags, photos, and the completion record the claim requires; re-winterization after each de-wint for inspection or repair.

Commercial and Institutional Buildings

Vacant retail, office, school, church, and municipal buildings that will not be heated: water systems drained and protected, sprinkler systems flagged for the owner's fire-protection contractor, and the work documented for the vacancy permit or the insurer.

Mothballed and Seasonal Property

Buildings closed for a season or an indefinite period, winterized as part of a mothballing plan and de-winterized on reopening with a pressure test before water is restored.

Field Capabilities

Winterization delivered with the rest of the vacant-property routine.

The winterization is verified at every inspection visit and reversed properly when the building comes back into use.

Dry, Wet & Radiant

The method matched to the heating system, priced and documented by type.

Re-Winterization

After a de-wint for inspection, showing, or repair, the system is protected again and re-tagged.

De-Winterization

Water restored with a pressure test, leaks found before they become damage.

Documentation

Tags, meter reading, and a photo of every drained system for the file.

Winterization Process

From shutoff to a tagged, photographed system.

Each step is photographed in order, so the record shows not just that the property was winterized but how.

01

Heating system type and scope confirmed

02

Water shut off and supply drained

03

Lines blown; heating system handled by type

04

Traps and fixtures charged; systems tagged

05

Photos and completion report submitted

To the Calendar

Winterized before the required window opens, and verified at every inspection through the end of it.

Method by System

Dry, wet/steam, or radiant — the right procedure for the heating system, not one procedure for every house.

Proof for the File

Tags, meter readings, and step photos that support the allowable, the claim, or the vacancy permit.

Common Questions

Winterization FAQ

What does winterizing a house include?+

Shutting off the water supply, draining the domestic lines and blowing them clear, draining the water heater, charging toilets, traps, and fixtures with antifreeze, and tagging every system with a winterization notice. Wet/steam and radiant winterizations add the hot-water or hydronic heating system. Every step is photographed.

When should a vacant house be winterized?+

Before the required winterization window opens for the state. Under the HUD and USDA schedules that is September 1 through April 30 in Ohio and Pennsylvania, and October 1 through March 31 in Texas, Louisiana, Alabama, Arkansas, and Oklahoma. For private property the same dates are a sound rule: winterize when the building will not be heated through the first freeze.

How much does it cost to winterize a vacant house?+

Investor programs publish the reimbursable amounts: dry winterization pays $100 under HUD, $120 under Freddie Mac, $150 under Fannie Mae and USDA, and $160 under VA, with wet and radiant methods priced higher. Ethreon prices private work by method and building; our 2026 price list post has every published allowable side by side.

What is the difference between dry, wet, and radiant winterization?+

Dry winterization covers a property with a standard domestic water system and no hot-water heating. Wet or steam winterization adds a boiler-based hot-water or steam heating system that has to be drained and protected. Radiant winterization covers hydronic in-floor or baseboard loops. Each investor program prices the three separately.

Do you re-winterize after an inspection or repair?+

Yes. When a property is de-winterized for an inspection, a showing, or plumbing work, the system is winterized again afterward and re-tagged. Re-winterization is a separate line item under every investor schedule and is documented the same way.

Can you winterize a rental property between tenants?+

Yes. A rental that will sit empty through freezing weather is winterized like any vacant house, and de-winterized with a pressure test before the next tenant moves in, so any leak is found before it becomes damage.

Do you winterize commercial buildings?+

Yes — vacant retail, office, institutional, and municipal buildings that will not be heated. Domestic water systems are drained and protected; wet-pipe fire sprinkler systems are flagged for the owner's fire-protection contractor, since they are not part of a standard winterization and are subject to their own code requirements.

Are there winterization services near me?+

Across Texas, Louisiana, Alabama, Arkansas, Oklahoma, Ohio, and Pennsylvania, yes. Home winterizations and vacant-property winterizations are performed by local Ethreon crews; if you need to winterize a rental or a vacant house in one of those states, send the address and the heating type.

What is de-winterization?+

Restoring water to a winterized property: removing tags, closing drains, refilling the system, and pressure-testing before fixtures are used, so a cracked line or failed joint is caught before water damage occurs. It is ordered when a property is sold, reoccupied, or reopened.

Have a property that will not be heated this winter?

Send the address and the heating system type if you know it. Ethreon confirms the method, schedules the winterization ahead of the window, and sends the tags and photos when it is done.
