- Temporary shoring while the house is open
- Full or partial floors over the existing house

Key Facts for a Second Story in Billerica
Old homesteads may hide aging wiring, original framing, or past repairs that only come to light once walls open. Whatever the lot, a second story keeps the existing footprint, so the work happens up top, with temporary shoring in place and dust barriers for the rooms below.
The starting point for a new floor:
- The footings below the walls
- Posts and beams the engineer may call for
- A place for a new staircase
- Shoring during roof removal
- Drains and supply lines for an upstairs bath
Building up may make sense if:
- The house is a ranch or a cape
- You need a primary suite on its own floor
- Building out would crowd the lot
- Bedrooms are full
- A garage could carry a suite above it
At the free estimate, we review the existing roof, where the new staircase can go, and the electrical panel, water heater, and HVAC, since each of them affect how the new level is laid out and what it costs.
Our process
Our Second Story Process in Billerica
Shoring holds your Billerica house steady while parts of the roof come off, and posts, beams, or larger footings are added where the engineer calls for them. After that the new floor, walls, and roof are framed and closed, the wiring, plumbing, and HVAC are run to the new level, and the finishes come last.

FAQ
Second Story Additions in Billerica: Common Questions
Adding a floor raises several common questions for Billerica homeowners. The answers below cover permits and the height review, whether the structure can carry a new floor, what happens to the roof, and the first step. If something is missing, call us, and we will explain the options.
Does building up in Billerica require a permit?
Yes, it does. Adding a floor calls for a building permit with structural drawings, and many towns review the building height and zoning. Our team works with the engineer, prepares the applications with the town, and books the structural, framing, systems, insulation, and final inspections.
Can my Billerica house carry a second floor?
It depends on what the engineer finds. Many houses were built to carry a roof, not another floor, so the engineer checks the foundation, the walls, and the floor framing before anything is drawn. When more strength is needed, we install beams, posts, larger footings, or new framing so the load reaches the foundation along a safe path.
Does the roof have to come off?
Most of the time, yes. Temporary shoring holds the house stable while the roof is removed in planned sections. For a partial addition, only one section may be opened. Materials are staged in advance, so the new floor is framed and closed quickly, with the open sections covered at the end of each day.
What happens first when I want to build up in Billerica?
It starts with a no-cost in-home consultation: book it on this page or call (978) 917-9072. We check the structure and the roof of your Billerica house, go over your plans for the new floor, and outline the structural evaluation before the design work. There is no obligation.
