What goes wrong in Middlesex County homes
Pre-1960 homes: galvanized pipe and cast iron
55% of homes in Middlesex County's covered ZIP codes were built before 1960, 40% of them before 1940. Houses that old often still have galvanized steel supply lines that rust closed from the inside, and cast iron or clay sewer pipe that cracks and lets roots in. Weak pressure at upstairs fixtures, brown water after a shutoff and slow drains are the usual clues. Typical fixes are whole-house repiping and a sewer camera inspection.
Oil-heated homes
13% of occupied homes here heat with fuel oil, far above the national norm. Many of them make hot water with a tankless coil inside the boiler, which runs the boiler all summer. Plumbers often replace the coil with an indirect tank or a standalone water heater when the boiler is serviced or replaced.
Natural gas in most homes
62% of occupied homes here heat with utility gas, so gas water heaters, ranges and dryers are common. That means gas line extensions for new appliances, flexible connector replacements and venting checks when a water heater is swapped. If you smell gas, leave first and call the gas utility from outside. See gas line repair.
Long, hard winters
74% of homes here were built before 1980, when pipes were more often run through exterior walls and uninsulated crawl spaces. In a long Massachusetts winter those are the lines that freeze and split. See frozen and burst pipe repair.
