Boardroom Screen Sharing Setup in Houston, TX 77019
Very little of 77019 was built to hold a display. The conference rooms here tend to be beautiful rooms that were something else first — a 1920s dining room now used by a family office, a panelled library in a converted bungalow off Dunlavy, a high-floor condominium amenity room on Allen Parkway. The technology has to arrive without announcing itself, and that constraint, not the equipment list, is what the job is really about.
Plaster, lath and load-bearing brick: the cable route is the whole job
In a new building the wiring is a line item. In a pre-war house off Kirby or Inwood it is the project, and everything else follows from where the cable can honestly go.
Walls from the twenties and thirties in this part of Houston are typically plaster over wood lath. The plaster is pushed through the gaps between lath strips and forms hardened keys on the back face, spaced every inch or so all the way up the cavity. A fish tape dropped from above does not glide past those — it catches, and the person pulling it applies more force, and the result is a hairline crack that runs eighteen inches across a hundred-year-old wall. It is also brittle to drill: a standard hole saw will chip the face unless the lath behind it is located first and the cut is scored.
Three more things regularly close off the easy route:
- Real dimensional lumber and horizontal fire-blocking. Old framing often carries a solid blocker mid-height in the cavity, which stops a vertical drop dead. It can be drilled, but only from a small opening that then has to be patched and matched.
- Masonry that is structural, not veneer. Where a wall is multi-wythe brick there is no cavity at all. The path has to go around, through an interior partition, or into surface moulding fabricated to match the existing millwork.
- A finished second floor. Once there is a room above, the attic route disappears and the run has to come from below or from a closet backing the wall.
The one advantage this area hands you: a great many Neartown and River Oaks houses sit on pier-and-beam foundations with real crawl space. A run underneath the floor to a discreet grommet or a floor plate under the conference table is often cleaner, faster and far less invasive than anything attempted inside a plaster wall. The first thing we check on a 77019 survey is whether we can get under the building.
Four ways to get a working room when nothing is allowed to show
Clients here are usually not asking for the largest screen. They are asking for a room that still looks like the room when the meeting ends. These are the approaches that survive that test.
| Approach | Best suited to | What it asks of the building |
|---|---|---|
| Millwork credenza with the display above | Converted dining and board rooms | A short wall chase behind the cabinet; ventilation cut into the cabinet back |
| Art-mode or framed panel | Rooms with a strong decorative scheme | Flush or recessed box behind the panel so it sits close to the wall |
| Lift cabinet or recessed screen | Panelled libraries where a black rectangle is unacceptable | Depth behind or below the joinery, and power inside it |
| Floor feed from the crawl space | Pier-and-beam houses with a central table | Access underneath and a small, neat floor penetration |
Two details decide whether these age well. The first is heat. Switchers, extenders and receivers put out real warmth, and sealed cabinetry cooks them; equipment installed in a closed credenza needs either passive venting cut where it will not be seen or a thermostatically controlled fan. Failures from heat do not look like heat failures — they look like a room that drops signal on hot afternoons.
The second is proportion. A panel chosen purely on the four-image-heights rule can overwhelm a twelve-foot room with a ten-foot ceiling and picture rail. Where that conflict shows up we will say so, and usually the answer is a smaller primary display plus a second surface, or a screen that disappears when it is not in use, rather than a wall dominated by a black rectangle.
Hard rooms sound wrong on the far end long before they look wrong
Screen sharing in 2026 almost always means somebody is joining remotely, and in these buildings the audio fails before the video does. Plaster walls, hardwood floors, tall windows with glass, and a heavy wooden table are all acoustically reflective. Sound bounces for a long time before it decays, and the room develops a noticeable tail.
The people in the room barely register it, because human hearing is very good at ignoring reflections it can also see the source of. A microphone cannot do that. It captures the direct voice and the tail together, and the far end hears what people describe as a barrel, a tunnel or an echo. Turning the microphone up makes it worse, because the reflected energy rises with it.
The echo cancellation built into meeting software is designed to remove the sound of your own speakers re-entering your microphone. It is not a reverberation remover. So the fixes are physical and they are ordinary:
- Get the microphone closer to the talkers — a table microphone in a hard room routinely outperforms a ceiling array that was specified on a drawing.
- Add soft mass that nobody has to notice: a large rug, lined drapery, upholstered seating, fabric-wrapped panels behind artwork, books on open shelving.
- Avoid seating the far-end microphone directly between a glass wall and a plaster wall, which is the most reflective axis in most of these rooms.
- Deal with the air handler. An old system serving a converted house is often the loudest thing in the room and sets the floor everything else has to rise above.
We test this rather than guess at it: a recorded call from the seats people actually use, played back, is more persuasive than any specification sheet.
Sharing a screen in a room where the content is privileged
A large share of the boardrooms we work in around West Gray, Kirby and Allen Parkway belong to law firms, wealth managers, single-family offices and private investors. What goes on the screen is not marketing material, and that changes several design decisions.
- A wired path is the conservative default. A cable carries the image between two devices and nowhere else. Every wireless system, however well built, introduces a radio link and a discovery mechanism that announces the room’s existence to devices nearby.
- Keep visitors off the business network. If guests present wirelessly, the receiver belongs on a segment that can reach nothing else — not the file server, not the printers, not the security system. A transmitter-button system that never touches the network at all is often the cleanest answer in a small firm.
- Turn off what you are not using. Many presentation receivers ship with casting protocols, remote-view features and cloud connectivity enabled. In a confidential room those get disabled deliberately and documented, not left on because they came that way.
- Hardware indication beats software indication. A camera with a physical shutter and a microphone with a mute that lights up tells everyone in the room the truth. A greyed-out icon on a screen nobody is looking at does not.
- Decide about recording before the first meeting, not during one. Rooms used for privileged conversations should have recording turned off at the device level, so the decision is not left to whoever is running the call.
We are a low-voltage contractor, not your compliance advisor. What we can do is build the room so the safe option is also the easy one, and hand over a written list of exactly what is enabled.
How the estimate runs in a 77019 building
The survey looks different here than it does in a leased suite, and takes longer, because more of the answer is hidden.
- Establish what the walls are. Plaster over lath, gypsum board from a later renovation, or solid masonry — each dictates a different route and a different mount.
- Look underneath and above. Crawl space access, closet backs, chases left behind by earlier renovations, and whether anything above the room is finished.
- Find the electrical reality. Older panels and older circuits; we confirm there is a place to put a receptacle behind the display that does not require a new home run across the house.
- Sit in every seat. Sightlines in irregular rooms with fireplaces, bay windows and beams are not something you can judge standing in the doorway.
- Listen to the room. Clap once, listen to the tail, note the air handler.
- Ask who else has to approve this. A building manager, a designer, an architect on a renovation, or an owners’ association with rules about anything visible from outside.
- Leave an itemized written quote that separates the display, the connection path, the audio and the patching, so nothing is a lump sum you cannot interrogate.
Finish protection is part of the work here, not an afterthought — drop cloths, dust control at every cut, and patching returned to a paintable state. EVOTECH IT LLC is licensed and insured, has been doing low-voltage work in Houston since 2004, and can provide a certificate of insurance to a building or an owners’ association on request.
What drives the price in this part of town, and what goes wrong
Two rooms of identical size in 77019 can differ enormously in scope, and it is rarely the equipment that separates them. We never quote a figure without seeing the room; these are what the figure responds to:
- Whether a usable route exists, or whether one has to be created through plaster, masonry or finished joinery.
- Crawl space access, and whether it is clear enough to work in.
- How much patching, matching and finish restoration the route generates.
- Whether the display is exposed, framed, recessed or hidden in a lift — each is a different install entirely.
- Custom millwork coordination, when a cabinetmaker has to build around the equipment.
- Whether remote participants are in scope, and whether the room needs acoustic help to serve them.
- Access and scheduling: occupied buildings, restricted hours, limited parking and no loading area.
The mistakes that generate a second visit
Equipment sealed into an unventilated cabinet, which fails in the summer rather than on install day. A television left in its retail picture mode, so the image is over-sharpened, motion-smoothed and slightly cropped. A microphone specified from a floor plan rather than chosen after listening to the actual room. A discovery protocol left switched on in a room where the owners assumed it was not. And the most common of all: a panel hung for the drawing, which makes the fireplace mantle the reference point and puts the image too high for anyone seated to watch comfortably for an hour.

Frequently asked questions
Can you install a boardroom display without cutting up our plaster walls?
Usually yes, though not always through the wall you expected. On a pier-and-beam house we often route beneath the floor and come up behind a credenza or at a floor plate, which avoids the plaster entirely. Where a wall route is unavoidable we open at as few points as possible, work around the lath rather than through it, and return the surface ready for paint. We will tell you honestly on the survey how many openings a given route needs before you agree to it.
Our conference room is a converted dining room with a fireplace. Does the screen go over it?
Sometimes, but it is worth resisting the reflex. Mounting over a mantle typically puts the image well above comfortable seated eye level, and for an hour-long meeting that becomes uncomfortable. It also places electronics above a heat source. Where the room allows, we prefer a different wall, a display over a lower credenza, or a screen that lowers into view. If the fireplace wall is genuinely the only option we measure sightlines from every chair first and set the lowest mounting position the hearth will allow.
Will a wireless presentation system work in a 1930s house?
It can, but expect the building to fight it. Plaster over wood lath, multi-wythe brick, old mesh or metal reinforcement in the plaster and cast-iron plumbing all attenuate Wi-Fi far more than modern construction. A receiver that tests fine in an empty room can struggle once the doors are closed and the room is full. We survey signal at the table rather than trusting a coverage map, and in these buildings we almost always put a wired connection in as well.
We are in a high-rise on Allen Parkway. Is it the same job?
No — a residential tower changes nearly everything about the logistics. The structural floor slabs are typically post-tensioned concrete and coring is generally not permitted, wall cavities are shallower, and the building will have its own rules on work hours, elevator use, insurance certificates and access. The technical design is similar; the approval and scheduling work around it is not, and we build that into the estimate rather than discovering it on install day.
Can guests present without joining our firm’s network?
Yes, and in a firm handling privileged material that is the design we would suggest. A transmitter-button system pairs a visitor’s laptop directly with the room receiver with no network involvement at all. If you prefer a software-based system, the receiver is placed on an isolated segment that can reach nothing else on your network, with unused casting and cloud features switched off and documented.
How long does a room like this take?
Far more of the schedule goes into route-finding and finish work than into equipment, so it varies more than it would in a modern building. A straightforward credenza-based room with crawl space access underneath is typically a single day. A panelled room with a lift cabinet, custom millwork coordination and plaster patching is a multi-visit project with a painter involved at the end. We give you the sequence in writing with the quote.
