Dense, walkable and packed with two-families, triple-deckers and converted condos, Malden keeps a plumber busy. IS Plumbing serves every corner of the city — Malden Square, Edgeworth, Maplewood, Linden, Bell Rock, Faulkner, Forestdale and Oak Grove — with licensed plumbing, heating, gas fitting and drain service for owners, landlords and condo associations alike. Reach us at +1 (774) 486-0909.
Most of Malden's housing went up before World War II, and it shows in the mechanicals: stacked units sharing a single water service, steam boilers in dirt-floor basements, cast-iron waste stacks running three stories, and condo conversions where nobody is quite sure which pipe belongs to which unit. We untangle exactly that — separating or upgrading water heaters for individual units, replacing corroded stacks, servicing steam and hot-water heat, and clearing the shared drain lines that back up into first-floor units first. Landlord and association work is a specialty, with clear communication for every occupant.
Malden is a full member of the MWRA system on both sides of the meter — Quabbin reservoir water in, wastewater out to Deer Island — so private wells and septic simply aren't part of the picture here. What matters instead is the age of everything between the street and your fixtures: services, meters and drain lines that can predate the Depression.
The City of Malden issues plumbing and gas permits through its inspectional services office, and multi-unit jobs often get an extra look — fair enough, given how many buildings share systems. The defining project in this housing stock is the cast-iron waste stack: when a century-old stack cracks, every unit above it is affected, and replacement takes permits, planning and tenant coordination.
Based in Millbury, MA, we cover all of Malden and the surrounding towns. Don't see your street? Call +1 (774) 486-0909 and ask.
Usually, yes. We install separate water heaters per unit where space and venting allow — a popular upgrade in Edgeworth and Faulkner two-families that ends arguments over the gas bill.
Yes. Steam boilers, radiator valves, banging pipes and uneven heat are familiar territory in Malden's pre-war housing, and when a steam boiler is beyond saving we quote its replacement honestly.
It depends on where the blockage sits — unit piping versus common stack. We locate the problem with a camera first, so the association and owners know exactly whose line it is before anyone pays.
Yes, on every job that requires one. We file the plumbing or gas application with the city, schedule the inspection and stay with it until sign-off.
Yes. Stack replacement is disruptive by nature — it touches every floor — so we plan access with tenants ahead of time, keep water off for the shortest possible window, and leave each unit clean.
