Ashburn by home ageService Area FAQs
Why does the age of my neighborhood matter for duct cleaning?
Ducts age differently than furniture collects dust. In a 1970s or 1980s home, loose joints, worn insulation and older materials matter more than dust. In a home built in the last decade, construction debris is the usual concern. Knowing when your home was built tells a technician what to inspect first.
Are Sterling, Cascades and Ashburn part of Dulles?
No. Sterling, Cascades, Countryside and Ashburn are separate census-designated places in eastern Loudoun County. Dulles is the unincorporated area around the airport, and the Dulles Town Center mall sits in Sterling. This site serves all of these communities but lists each one under its own name.
