Lobby TV Installation in Katy, TX 77491

Plenty of Katy reception rooms were built long before anyone planned for a screen: a brick storefront near the railroad, a church foyer with a two-story wall, an older house turned into a law or insurance office with the waiting area in what used to be the living room. EVOTECH IT LLC installs lobby TVs in buildings like these so the screen looks as if it was always meant to be there, with no cable across the brick, no cracked plaster and no cord trailing to the baseboard.

A mailing ZIP with some of Katy’s oldest lobbies behind it

77491 is mostly a post-office-box ZIP, so the address on the letterhead does not tell us where the screen will hang. In practice, many of the organizations that use a Katy P.O. box, such as congregations, family businesses, small professional firms and nonprofits, work out of the older part of town around Highway 90 and the railroad, or out of buildings that have been remodeled more than once. That building stock is what this page is written for.

An older building is harder than a new office because there is nowhere obvious to hide anything: no suspended ceiling to carry cable, walls of solid masonry or plaster, and owners who care how the room looks. The engineering problem is concealment and anchoring, not the television.

Four walls we meet in older Katy buildings, and how each is handled

WallHow we identify itWhat actually holds the mountHow cable gets in
Solid brick (older storefronts, some church walls)Visible mortar lines, a dense sound, full depth showing at a window jambSleeve or wedge anchors set into the brick face rather than the mortar joint; adhesive anchors with screen tubes where the brick turns out to be coredA painted surface raceway, or a route from above or below; we avoid cutting channels into brick
Plaster on wood lathHard, slightly wavy surface; lath visible beside an outlet boxLag bolts into the wood studs behind; the plaster itself carries nothingFished down the stud bay after drilling the plaster slowly with hammer action off
Shiplap, beadboard or wood panelingBoard seams and nail headsLags through the boards into studs, with the plate placed so seams stay straight and visible lines stay unbrokenA board can sometimes be lifted and re-nailed to hide a pass-through
Drywall over wood studs (later remodels)Hollow sound; a stud finder reads reliablyLag bolts into stud centersA low-voltage bracket for signal, plus a receptacle behind the screen

Older walls rarely stay one material. A front wall may be brick behind furred-out drywall, with an air gap that swallows short anchors, so we drill a small test hole where the screen will cover it before choosing hardware. A wrong guess on brick leaves holes that never patch invisibly.

Hiding power and signal when there is no ceiling grid

Without a drop ceiling, we look down and up before we look sideways.

Through the crawlspace

Pier-and-beam foundations are common under older houses and small commercial buildings in Katy. With a raised floor, the crawlspace is often the cleanest path: down through the bottom plate behind the screen, under the floor, and back up behind the reception desk or into the closet holding the player and network gear. The cable is supported on the framing, never left in the dirt.

Through the attic

With an accessible attic, cable drops down the stud bay from the top plate. Summer attic heat around Houston punishes people and electronics, so attic work happens in the morning and extenders and players stay out of the attic entirely.

Open stud bays in the oldest framing

Some of the oldest wood buildings were balloon-framed, with stud bays running uninterrupted from floor framing to roof framing. Fishing cable through them is easy, but those open bays also let fire travel. Any hole we make through a plate or blocking is sealed with fire-rated sealant before we close up.

When nothing can go inside the wall

On solid brick with no route above or below, a slim surface raceway is the honest answer. Painted to match and run straight along a line the eye already follows, like a door casing, an inside corner or the edge of a column, it nearly disappears. A cord cover stuck at an angle across brick never does.

When the waiting room used to be a living room

Law, insurance, real-estate, counseling and dental practices around old Katy often occupy remodeled houses. The front room becomes the lobby, and it brings three quirks with it.

  • Short viewing distance. The farthest chair may be ten or twelve feet away, so a 43- to 55-inch screen is plenty. A 75-inch set in a small front room dominates it and makes every line of text feel like shouting.
  • A fireplace on the best wall. Mounting over a mantel puts the screen high and, if the fireplace is still used, in rising heat. When the fireplace is decorative, the chimney breast is often solid masonry that anchors well. We check the screen maker’s heat and placement guidance and measure the neck angle from the chairs before recommending it.
  • Old circuits. Older wiring may offer few receptacles, some of them ungrounded. The screen and player want a grounded receptacle behind the panel. That is licensed electrician’s work, and we coordinate it so the receptacle lands exactly where the mount needs it.

Counseling and medical offices here should keep sound off beside a thin session-room wall and never show appointment names on a screen visible through the front window.

Church foyers and fellowship halls: tall walls, rotating volunteers

Older Katy churches add height and history to the job. Foyer walls are often tall, and the screen has to sit high enough to be read over a crowd at the doors after a service. That usually means a lift or scaffold instead of a stepladder, and a mount chosen for a steep downward tilt.

The harder part is people. Volunteers who update announcements change every few months, so we set up a workflow a newcomer learns in five minutes: a shared folder the signage player watches, or a web dashboard whose login stays with the church office. Service times and event slides in English, Spanish or any other language can be scheduled to appear before services and disappear afterward.

A fellowship hall used for meals and presentations can get an HDMI or wireless presentation plate for a guest speaker’s laptop, returning to the announcement loop when unplugged.

What happens on an EVOTECH lobby TV call in Katy

First visit. We walk the room with whoever will live with the screen: the office manager, the pastor, the facilities volunteer. We identify the wall construction, look for the crawlspace hatch or attic access, find the nearest grounded receptacle and network jack, and sit in the chairs to judge height. The itemized quote lists each part of the route separately, so you can compare a fully concealed path with a painted raceway and decide.

Before install day. If an electrician is needed for a receptacle, that is scheduled first. If the building is owned by a board, a congregation or a landlord, we confirm in writing which walls may be drilled.

Install day. Drop cloths and dust capture go down before the first hole, because plaster and brick dust travel. Cable is pulled, anchors set, the screen hung and every cable dressed out of sight. Patching of access holes is agreed at the estimate, so the finished wall holds no surprises.

Setup and handoff. We configure the source and switch off the features that make a TV behave like a home set, such as sleep timers, store demo mode and automatic input switching. We set on and off hours and confirm the screen recovers by itself from a power cut. The person responsible for content gets a walkthrough and a one-page note.

Why two lobby installs in the same town price differently

  • Masonry versus framed walls, and whether brick is solid or cored
  • The length of the concealed route and whether the crawlspace or attic is accessible
  • Wall height, and whether a lift or scaffold is needed
  • An electrician’s visit for a new grounded receptacle
  • Extra inputs, such as an HDMI or wireless presentation plate for guest laptops
  • Whether you supply the screen or we source one
  • The content platform and who will manage it
  • Working-hour limits around services, office hours or events

No figure on a website can account for a crawlspace hatch that has been nailed shut or a brick wall with a hollow core. Book an on-site estimate and each of those items appears on the quote as its own line.

Mistakes that bring an installer back to an older building

  • Hammer-drilling plaster. The vibration breaks the plaster keys behind the surface and cracks spread well beyond the hole. Plaster is drilled slowly, hammer off, with tape over the spot.
  • Anchoring in the mortar joint. Older, softer mortar crumbles under load. Anchors go into the brick itself, and cored brick gets adhesive anchors rather than expansion anchors that have nothing to grip.
  • Trusting the plaster or lath. A toggle in lath feels solid on the day and loosens over months. Every fastener lands in a stud or masonry.
  • Leaving store demo mode on. Some sets revert to demo brightness and banners after an update unless it is properly disabled.
  • Mounting over a working fireplace without checking. Heat, a steep viewing angle and a screen at the wrong height for the room are all avoidable with ten minutes of measuring.

Frequently asked questions

Can you hang a TV on a brick wall without the cable showing?
Often, yes. If there is a crawlspace, attic or adjacent framed wall, we route power and signal through it and come out directly behind the screen. When the brick is solid with no route in, a slim painted raceway along a corner or casing is the cleanest option, and we will show you where it would run before anything is installed.
Will drilling crack our plaster walls?
Not when it is done carefully. We drill plaster slowly without hammer action, protect the surface first and anchor only into the studs behind it. The damage people remember usually comes from a hammer drill and anchors that rely on the plaster for strength.
Our office is an older house on pier-and-beam. Does that help or hurt?
It usually helps. A raised floor gives a hidden path for cable from the wall behind the screen to a closet or reception desk. We support the cable on the framing rather than leaving it on the ground.
Can church volunteers update the slides from their phones?
Yes. With a cloud signage player the slides are managed from a web dashboard or a shared folder. We set it up so the login belongs to the church office, which keeps things running when volunteers change.
Can the screen go over our fireplace?
Sometimes. If the fireplace is decorative, the chimney breast is often a strong mounting surface. If it is used, heat and viewing angle need checking against the screen maker’s guidance first. We measure both at the estimate.
Do you install the electrical outlet too?
EVOTECH handles the low-voltage side: mounting, signal, network and setup. A new line-voltage receptacle is installed by a licensed electrician, and we coordinate the timing and placement with them or with your own electrician.
