What We Offer for Furnace Repair in Dover
- Two-family and converted houses are common, so one boiler and one waste stack often serve more than one apartment — that changes how a repair gets staged and priced.
- Original cast iron waste lines and older sewer laterals mean slow drains and repeat backups are frequent, and a camera inspection usually settles whether it is a clog or a broken section.
- Basements here are tight with narrow stairs, so getting an old boiler out and a new one in is part of the job plan, not an afterthought.
- Older galvanized supply piping still turns up in the oldest blocks, and it scales shut from the inside long before it ever leaks.
