Duplex and triplex invisible grills covering every level in one visit
Multi-level homes have more openings than a single-floor apartment — balconies on two or three floors, internal staircases, and sometimes a terrace — and it's easy to focus on the main living-room balcony while overlooking a smaller bedroom balcony upstairs.
A typical duplex has balconies on each floor plus at least one internal staircase connecting them; a triplex adds a third level and often a terrace. Each of these is a separate opening with its own bracket and tensioning requirements, so we survey the entire home in one visit rather than quoting floor by floor.
Internal staircases in multi-level homes are a commonly missed fall risk specifically because they're indoors and don't feel like an 'outdoor' safety concern the way a balcony does — but an open stairwell is a genuine risk for a young child moving unsupervised between floors, and we recommend including it in the same project.
Coordinating all levels in a single visit lets us plan consistent cable spacing, grade and finish across the whole home, rather than treating each floor as an unrelated job with potentially different vendors or specifications over time.
Because of the larger total scope, multi-level projects typically get a lower effective per-sq.ft or per-running-foot rate than booking each balcony separately, similar to how a full-building project prices better than individual unit bookings.

Frequently asked questions
Should internal staircases be included in a duplex project?+
Yes, we recommend it for any home with young children, since open internal staircases are a genuine and often overlooked fall risk.
Is it cheaper to do all levels together versus one balcony at a time?+
Usually yes, due to volume pricing across the full project versus booking each opening separately.
How long does a typical duplex project take?+
A duplex with 2-3 balconies plus a staircase usually takes a single extended visit, longer than a standard one-floor apartment but still completed within a day for most homes.
