Deck & Balcony Installation · CSLB #1060736
Commercial Deck & Balcony Installation in California
We install decks and balconies across the Bay Area, Central Valley, and Sacramento — for apartment communities, condominiums, HOAs, and hotels. On a commercial property an installation is rarely one deck. It’s one deck repeated across a building, which means the specification matters more than the craftsmanship on any single element — and so does every mistake in it.

01 Why it matters
On a commercial property you aren’t installing a deck. You’re installing forty of the same one.
A single deck rewards good carpentry. A property full of them rewards something else: a specification that’s right before the first one goes in. Whatever you decide about joist spacing, hardware grade, flashing at the wall, and how the boards meet the threshold gets repeated on every element on the building — and so does whatever you got wrong. A detail that costs a few dollars to correct on one deck costs forty times that after the fact, and by then the access, the staging, and the resident notices have all been paid for once already.
That changes what an installation quote should contain. The specification belongs in it explicitly — not “composite decking” but which line, at what joist spacing, on what hardware, with what detail where the deck meets the building. On a programme those decisions are the product. The carpentry is the easy part.
The second thing that separates commercial installation from residential is that the building stays occupied. Residents keep using their doors, their walkways, and their parking while the work moves along the elevation. A programme that ignores that stalls the first time someone can’t get home, which is why sequencing is priced rather than assumed.
Get the detail wrong on one deck and you’ve made a mistake. Get it wrong on the specification and you’ve made it forty times.

02 The D&B difference
What installation should involve
We install to a written specification, across a whole property, without closing it down.
The specification is agreed before the first element
Joist spacing matched to the surface, hardware grade set for the exposure, flashing detailed at the wall and at the threshold, and all of it written down. On a programme this is what you’re actually buying.
The first one is a prototype, not just the first one
We build one element, walk it with you, and confirm the detail before it’s repeated. Changing something on element one is a conversation. Changing it on element twenty-two is a rework order.
Sequenced around residents
Access, staging, and phasing planned so people keep reaching their doors throughout. On occupied buildings that’s the constraint the schedule is built around rather than an inconvenience absorbed later.

06 Investment
What installation costs
The cost of deck installation is quoted after a survey, and on a commercial property the per-element number depends heavily on how many elements there are.
What drives the number
- Number of elements, since mobilisation, staging, engineering, and permitting are paid once across a programme rather than repeatedly
- Elevation and structure — ground-level decks price very differently from elevated balconies
- Footings, and what the ground turns out to allow
- Decking material and the joist spacing it requires
- Waterproofing where the element sits over occupied space
- Railing length and stair runs, priced by length and count rather than area
- Access, staging, and phasing around residents
- Permits and engineering where the scope requires them
Why programmes price better per element: the fixed costs of getting a crew onto a property and through plan review don’t multiply with the number of decks. Forty elements installed as one programme cost meaningfully less each than forty installed separately — which is worth planning around rather than discovering after the first ten.
Why published per-square-foot figures mislead: a rate for decking installation is boards and labour on an assumed sound frame. It excludes footings, framing, flashing, railings, stairs, and the access provisions an occupied building requires — which together usually exceed the surface. Compare scope rather than rate.
What to compare between bids: the specification, not the total. Ask each contractor to name the joist spacing, the hardware grade, and the detail where the element meets the building. A bid that can answer those three in writing has thought about the programme; one that answers with a material and a size has quoted the boards. On a forty-element property that difference is the whole project.

07 Project example
A recent installation project
An apartment community was installing private patio decks at every ground-floor unit. The specification came to us as a material and a size, which is how most of them arrive. We wrote the rest into it before pricing: joist spacing set for the composite line chosen rather than for timber, hardware grade specified for the irrigation running along that elevation, and a detail at the door threshold so water leaves the deck rather than standing at the sill. Then we built one and walked it with the manager before the other elements started. Two things changed at that walk — the board direction at the threshold and the height of the step down to the path. Both were five-minute conversations on element one. On element twenty they would have been a rework order.
They built one and asked us to walk it before doing the rest. Two things changed. Neither would have been fixable later. Regional Property Manager · California apartment community
09 Client feedback
What property managers say
They wrote the joist spacing into the scope. The last contractor quoted the same boards and laid them on a frame that was too wide for them.
One element built first and walked before the rest. Two things changed, and neither would have been fixable across forty decks.
Residents kept reaching their doors the whole way through. That’s not something the other bids had thought about at all.
10 FAQ
Installation questions
What does deck installation cost?
On a commercial property, it depends heavily on how many elements there are. Mobilisation, staging, engineering, and permitting are paid once across a programme rather than repeatedly, so forty decks installed together cost meaningfully less each than forty installed separately. Beyond that, the cost of deck installation is driven by elevation, footings, material and the joist spacing it needs, railings, stairs, and the access provisions an occupied building requires.
Why do published decking installation costs never match the quote?
Because a published rate is boards and labour on an assumed sound frame. It leaves out footings, framing, flashing at the wall, railings, stairs, and the phasing an occupied building needs — which together usually exceed the cost of the surface everyone compares. Two quotes at the same per-square-foot rate can differ by half on scope alone.
Can you do deck board installation on our existing frames?
If the framing is sound and the spacing suits the boards, yes — and it’s much the cheaper route. What has to be checked first is joist spacing, because composite and Trex need closer support than most older frames were built for, and laying them over a frame that’s too wide produces flexing and cracking with no warranty recourse. We measure before quoting a board-only installation.
What’s involved in adding a balcony to an existing building?
The question is where the load goes, not whether it can be done. Adding a balcony to an existing wall means carrying it on posts to the ground, hanging it from the structure, or cutting into the floor system — three routes with very different costs and permit scopes. We assess the wall and the floor before drawing anything, and the balcony installation cost follows from which of those the building allows.
Why build one element before the rest?
Because a detail is a conversation on element one and a rework order on element twenty. We build the first deck or balcony, walk it with you, and confirm board direction, threshold detail, step heights, and railing terminations before the programme repeats. It adds a day and it’s the single cheapest risk control available on a multi-element programme.
What gets checked at that walk is usually mundane and always specific: which way the boards run where people step out of the door, how far the surface sits below the sill, where the step down to the path lands, and whether the railing terminates cleanly at the wall. None of it appears on a drawing and all of it is what residents notice first.
What should a specification actually contain?
More than a material and a size, which is how most arrive. It should name the decking line, the joist spacing that line requires, the hardware grade for the exposure, the flashing detail where the element meets the building, and how the surface meets the door threshold. On a programme those decisions are the product — and they’re the ones that get repeated on every element.
Can you install while the building stays occupied?
Yes, and it’s most of what we do. Work is sequenced so residents keep reaching their doors, their walkways, and their parking throughout. That planning is priced as part of the job rather than assumed, because a programme that ignores it stalls the first time somebody can’t get home.
Practically it means notices go out with real dates rather than ranges, one element is open at a time on any given stair or walkway, and the site is left safe at the end of each day rather than at the end of the phase. Managers field more complaints about access and noise than about anything structural, and a schedule that anticipates that is worth more than a slightly lower number.
Do you install on new construction as well as existing buildings?
Both. On new construction we work to the architect’s drawings and flag anything in them that won’t perform — a joist spacing that doesn’t suit the specified boards is the one we raise most often. On existing buildings the survey comes first, because what the wall and the floor allow decides the design.
Does new installation trigger SB 721 or SB 326?
It puts the element into the cycle. A wood-framed deck or balcony more than six feet above grade at a property with three or more units carries a repeating inspection obligation from the day it’s built. We hand over as-built documentation at completion so the first inspection starts from a record rather than from scratch.
