Fewer than half of Woburn’s housing units are single detached homes. The rest is triple deckers, converted two-and three-families, and apartment buildings, the old New England mill-city pattern, and it changes what a wet basement usually means: not one household affected, but sometimes two or three under the same roof, each blaming a different cause.
What a Forever Dry System install runs in Woburn
We price full-perimeter interior drainage with a sump pump and dehumidifier after seeing the actual foundation, not before. Linear footage and how the water is entering both move the number. Book a free inspection and we will hand you a written figure the same visit.
The floor wall joint, and why it matters more in a multi-unit house
Most water enters where the foundation wall meets the basement floor, the floor wall joint, because that seam is where hydrostatic pressure from saturated soil finds the path of least resistance. In a single-family house, that is one owner’s problem to solve on their own timeline. In a multi-unit building, it is a shared foundation with shared consequences, and coordinating a fix across multiple units or owners takes more planning than a standard job.
What actually goes in
- A drain cut along the full perimeter at the floor wall joint, catching water before it reaches the room
- A sump pump, sized to the house and the number of units it serves, pumping that water back outside
- A vapor barrier on the walls, stopping moisture from wicking straight through the block
- A dehumidifier, keeping the air dry enough that mold never gets started
What we hear about most: the basement someone else already “fixed”
A lot of Woburn’s housing changed hands more than once before it got to its current owner, and a common story is a basement that a previous owner or a flipper painted, or sealed with a waterproofing paint from a hardware store, before selling. That paint holds back moisture for a while and then fails all at once, usually after the new owner has already moved things into the space. If your basement was “already waterproofed” by someone who was not us, we will tell you honestly whether that work is doing anything or just hiding the problem behind a coat of paint.
What a shared foundation actually means for cost
In a two- or three-family building, the drainage system usually has to run the full perimeter of the foundation even if only one unit is reporting a problem, because the foundation is one structure regardless of how the units are divided above it. That is the main reason multi-family jobs in Woburn tend to cost more than a comparable single-family job: not a different system, just more linear footage of the same system.
Woburn’s housing stock, and why age matters more than size
Census data puts Woburn’s median home at built-in-1970, and just under half the housing stock is single-family, the rest is two- and three-family and condo conversions. Whatever drainage system came with the original foundation is now more than fifty years old regardless of which category the building falls into. That is the detail that actually predicts a wet basement here, more than street or neighborhood: a system installed in 1970 was never built to last the life of the house, and most of what 603 gets called out for in Woburn is exactly that. Not a new problem. An old system finally done working.
Check these before you call us
Two things cause a wet basement: surface water and groundwater, and they get fixed differently. Before booking an inspection, walk the foundation during or right after a hard rain. Are the downspouts dumping water within a few feet of the wall? Extend them and watch what happens over the next storm. Does the ground still slope away from the foundation for the first six feet, or has decades of settling tipped it back toward the house, which happens on a lot of older Woburn lots? If fixing both of those does not change anything, what you have is groundwater working its way in from below the frost line, and that is the problem the Forever Dry System is built for.
Frequently asked questions
I own a multi-family building. Does the whole basement need work, or just my unit’s section?
Usually the whole foundation, since water does not respect a unit line. We will walk the full space with you and explain what is shared versus what is specific to one section.
My tenants are on different floors. Will this disrupt anyone above ground level?
No. The work stays in the basement. Upper units are not affected.
Do you have to break up the whole floor?
No. The system runs along the perimeter. The middle of the floor stays untouched.
How long is a typical job?
Most run a few days. Larger multi-unit foundations can take longer, we will give you a specific estimate after the inspection.
What a recent customer told us:
We recently hired 603 for a full basement waterproofing with demo. They did a FANTASTIC job! The crew worked hard every day to make sure the project finished on time. From the initial sales visit to the final walk-through, everyone was great to work with.
