Historic Structures

Weatherseal Insulation has had the pleasure of working on a large number of historically significant homes and estates throughout the state of Virginia. Among them:


Monticello is among the most historically significant buildings in the United States. Designed by Thomas Jefferson after inheriting land from his father at the age of 26, the estate served as the third president’s primary plantation for the duration of his life.

Weatherseal Insulation recently conducted an energy audit of Thomas Jefferson’s mansion at Monticello, including an infrared scan of the attic to assess insulation and air leakage rates.

Keswick Hall

Keswick Hall is an historic hotel, club and estate located near the Blue Ridge Mountains and Monticello. A popular destination for tourism, golf, weddings and events, the lavish hotel was designed to resemble a classic Virginia estate rather than a modern hotel. Keswick Hall was awarded Conde Nast’s “#1 Small Resort in Mainland U.S.” award for two consecutive years in 2010 and 2011.

Farmington Country Club

Farmington Country Club is a prestigious country club located in Charlottesville, near the University of Virginia. The octagonal East Wing of the clubhouse was designed by Thomas Jefferson and constructed in 1802 as an addition to the original building.

Originally a plantation mansion, the clubhouse of the Farmington Country Club is now a more energy efficient historic building thanks to the work of Weatherseal Insulation.


Montalto, meaning “high mountain,” is a part of the Monticello estate that was purchased by Thomas Jefferson in the 1770’s. Jefferson was the first to refer to the mountain as Montalto, which is sometimes called Brown’s Mountain.

The 11,000 square foot renovated 1908 Country House that stands atop Montalto is aptly called “Repose.” It is a popular destination for weddings and other events; and, thanks to Weatherseal Insulation, it is now a more comfortable and more energy efficient building than ever.

Former Home of Partick Henry

Jane Fisher and Michael Bowles found a gem when they purchased their 200-acre farm and house where Patrick Henry once resided, one of the most historic dwellings in Louisa County. But with history can come many energy efficiency challenges. Although there had been attic upgrades with the previous owners and the installation of a high efficiency ground source heat pump, they was plenty of room for improvement especially with the building envelope. They enlisted the help of Weatherseal to oversee the insulation and air sealing fixes, and have a more comfortable home now aged — and improved — to perfection.
