Home Air Sealing in Viola, DE

Older homes are notorious for leaking air.  Air leaks mean loss of energy and increased utility costs of heating and air conditioning. This problem is typically caused by many factors. This home in Viola, DE had leaky basement windows which were replaced with EverLast™ vinyl windows. But perhaps one of the biggest losses was occurring around the fireplace damper. These are hard to seal and result in huge amounts of energy loss. Lawson Home Services installed a Airtight Spring Top Chimney Cap , which is operated by a cable connecting it to the damper control. This certain helped reduce the the air leak in this home.
