Walk into any second-floor office above the shops ringing Marietta Square and you’ll notice the exposed brick before you notice anything else. Original 1900s masonry, tin ceilings, heart pine floors that creak in exactly the spot where the router is sitting. It’s the kind of space that makes a business look established. It’s also the kind of space that makes a wireless access point behave like it’s broadcasting through a bunker wall, because in a lot of these buildings, it basically is.
Brick and plaster construction from that era wasn’t designed with anything electronic in mind, let alone a building full of laptops, point-of-sale terminals, security cameras, and cloud-based phone systems all competing for the same signal. A single load-bearing brick wall can cut wifi throughput by half. Add lath-and-plaster interior walls, metal lath in particular, and a signal that reads fine in the front office can drop to nothing in the back storage room forty feet away. Business owners who lease these spaces usually find this out the hard way, after they’ve already signed the lease and moved the file cabinets in.
The conduit problem nobody mentions during the walkthrough
Running new network cabling through a modern build-out is straightforward. Drop ceiling, open studs, done in an afternoon. Running cable through a building on the National Register of Historic Places, or one that’s simply old enough that nobody kept the original blueprints, is a different exercise entirely. Exterior walls often can’t be touched without a preservation review. Interior walls might be solid brick with no cavity to fish a line through. Conduit that does exist was sized for phone lines from decades ago, not the fiber or Cat6 runs a modern point-of-sale system or VoIP setup needs.
This is where a lot of small businesses around the square end up improvising in ways that create problems downstream: a mesh of extension cords, wifi extenders stacked three deep, a hotspot from someone’s personal phone plugged in as a permanent fallback. Those fixes work until they don’t, usually during a busy Saturday when the boutique’s card reader can’t reach the network and there’s a line at the register.
Landlords, leases, and who actually owns the problem
Commercial leases in older Marietta buildings frequently put the tenant on the hook for anything inside the walls while the landlord controls anything structural. That split matters more than most new tenants realize. A tenant can pay to have an electrician run new low-voltage cabling, but if that cabling needs to cross a wall the landlord considers structural or historically protected, the request goes into a queue that can take months. Businesses that don’t plan for this before signing a lease often spend their first year operating on compromises they never intended to live with.
- Signal loss through masonry: Interior brick and plaster walls in pre-1950s construction can reduce wifi signal strength enough that a single access point rarely covers more than one room reliably, which means multi-room offices usually need distributed access points rather than one central router.
- Limited pathways for new cable: Buildings without dropped ceilings or wall cavities often require surface-mounted raceway or conduit, which changes both the cost and the timeline of any network upgrade compared to a newer build-out.
- Power constraints: Older electrical panels weren’t sized for the number of devices, chargers, and networking equipment a modern small business runs, and circuit overloads in these buildings are common enough that electricians who work the square see it repeatedly.
What actually works in these spaces
The businesses that solve this well tend to do a few things differently. They map the building’s actual wifi dead zones before deciding where equipment goes, rather than assuming the router should sit wherever the internet line happens to terminate. They use mesh systems or multiple access points tuned to cover masonry-heavy floor plans instead of relying on one powerful router to push through walls it can’t penetrate. And they get a real assessment of what’s structurally possible before committing to a lease renewal or a build-out plan, so they’re not discovering conduit limitations after the fact.
This is also where local knowledge starts to matter more than it would in a newer commercial corridor. A provider offering managed IT services Marietta businesses actually rely on tends to have already dealt with a dozen buildings just like the one on the square, and knows which landlords are flexible about running new lines and which buildings need a workaround from day one. That familiarity saves the guesswork that otherwise turns into weeks of trial and error with extension cords and range extenders.
The cost of treating it as a minor inconvenience
None of this is dramatic on its own. A slow wifi signal in a back office isn’t a crisis. But it compounds. A card reader that intermittently loses connection costs sales. A security camera system that drops its feed during the exact hours nobody’s watching it defeats the purpose of having cameras. A phone system that cuts out mid-call with a client makes a business look less reliable than it is, regardless of how good the actual work is. Buildings with character carry real infrastructure tradeoffs, and businesses that plan for those tradeoffs upfront spend a lot less time firefighting later.
