Insulation for Lake Fork Country
Spray Foam Insulation in Yantis is mostly lake work. Wikipedia describes Yantis as a town of 405 people at the 2020 census, surrounded on three sides by Lake Fork Reservoir, at the junction of State Highway 154 and FM 17 about 12 miles north of Quitman. Around the lake you find full-time homes, retirement places, weekend houses and fishing cabins, and the buildings people keep their boats and gear in.
Houses that sit empty part of the week
A weekend house is closed up for days at a time in the summer heat, often with the AC set high or turned off. When it is opened, the attic has been baking and humidity has built up inside. A sealed, insulated attic and a tight floor help the house cool down faster and hold humidity down while it is empty. For houses on piers near the water, closed-cell foam under the floor works better than batts, which tend to sag and fall in damp air.
Boat barns and storage
Steel buildings for boats and equipment drip when humid air off the lake hits cold metal. A coat of closed-cell foam bonded to the panels stops that, and it keeps mud daubers and mice from nesting behind loose blanket insulation. If the building also has a shop or a bunk room, we spec those areas separately.
A town with a long past
The area was settled as early as 1860, had a gristmill and cotton gin by 1870, and got its own post office in 1885, named for postmaster George R. Yantis. The Yantis Oilfield was discovered in 1947, and the town incorporated in the late 1960s, before the reservoir was built. So the older houses in town predate the lake, and the newer ones grew up around it.

Yantis Questions
Is spray foam a good idea in a lake cabin?
Often, yes. Closed-cell under the floor and foam or deep blown-in in the attic help a cabin cool faster and stay drier when it is closed up.
How do I stop my boat barn from dripping?
Closed-cell foam bonded to the steel panels stops condensation by keeping humid air off the cold metal.
Do you schedule around weekend use?
Yes. Many lake jobs are done midweek while the house is empty, which also gives the foam time to cure.
