Audio-Video Installation in Houston, TX

Start with the building: a Houston AV matrix

Before we talk about screens and speakers, we want to know what the walls, floors and ceilings are made of and who else has a say in changing them. In Houston that answer varies more from block to block than almost anywhere else in Texas.

Condo towers: building rules come before the wiring plan

Most Houston high-rises want a written scope of work and a certificate of insurance from the contractor, naming the association or management company, before anyone is allowed upstairs. On top of that come a freight elevator reservation, a loading-dock or garage arrangement for our vehicle, and permitted work hours. We ask you for the building’s contractor packet early, because a missing document can cost a scheduled day.

The structure itself sets hard limits. Many towers are built with post-tensioned concrete slabs, which contain steel tendons under enormous tension. Drilling or coring into a slab without the building’s approval and a scan of what is inside it risks damaging a tendon, so many associations simply prohibit it. That means no new in-ceiling speakers under a bare concrete ceiling and no cable dropped through the floor. Instead we use existing soffits and furred walls, and where those do not reach we fit slim raceway painted to match the wall.

Walls vary too. Interior partitions are often light-gauge steel studs, which need the right hollow-wall hardware or added backing for a heavy TV, while columns and exterior walls are concrete and take masonry anchors. Low frequencies travel through a concrete frame into the units around you, so subwoofers go on isolation pads, away from shared walls, and get set to sensible levels. In a tower surrounded by dozens of neighboring wireless networks, we also cable every streaming box and console that we can reach instead of leaving it on congested Wi-Fi.

Townhomes: tall, narrow and wired from the garage up

The typical inner-city townhome puts the garage and a small bedroom on the ground floor, the kitchen and living room on the second, bedrooms on the third, and sometimes a roof deck on top. The builder’s media panel usually sits on the ground floor, which means every run to the living room TV or the deck climbs one to three stories through walls with fire blocking at each floor line.

• The shared wall. The wall between you and the next unit is normally a fire-rated separation. We do not recess boxes into it or pierce it; the TV goes on an interior wall where possible, and any required penetration is sealed with a listed firestop.
• The roof deck. Outdoor-rated TVs and speakers only, mounts sized for wind load, and cable brought up through existing sleeves. Sealing roof penetrations belongs to your roofer or builder, and we coordinate rather than improvise.
• The ground-floor panel. In lower-lying parts of the city, we avoid putting amplifiers, network gear or a rack at floor level in the garage. Mounting it higher on the wall costs little and protects it from the water that some neighborhoods see in heavy storms.

Bungalows and cottages inside the Loop

Pier-and-beam houses are some of the easiest places in Houston to hide cable, provided there is crawling room underneath. We can often drill up through the floor inside a wall cavity, run beneath the house and come up exactly where the equipment lives, leaving no visible trace in the rooms. We check clearance, moisture and anything living down there before we commit to that route.

The walls themselves take more care. Many older homes have horizontal shiplap boards nailed across the studs behind the drywall, or original plaster on lath. Shiplap lets a cable drop vertically within one stud bay but blocks sideways travel, and plaster cracks if it is cut carelessly, so we score it and cut small openings. If we find ungrounded outlets or old knob-and-tube wiring at a planned TV location, we stop and recommend a licensed electrician before any new display is powered from it. Houses in a designated historic district may also need city review for changes visible from the street, so exterior speakers or antennas are worth checking first.

Offices, restaurants and venues across the city

Conference and training rooms

Whether the office is in the Energy Corridor, Westchase, Greenway Plaza or downtown, a meeting room works when the display is sized for the farthest chair, the camera sits near eye level at the screen, the microphones cover the whole table and a guest can connect a laptop with one cable. We plan those four things first, then pick hardware that matches your video-conferencing platform.

Restaurants and bars

Showing different games on different screens takes a matrix switch or an AV-over-IP system rather than splitters, and a patio should be its own audio zone with its own volume. Commercial displays built for long daily run times are worth it over consumer TVs in a busy room. Background music in a business generally requires a service licensed for commercial use, which is the owner’s decision; we wire the zones for it.

Ceilings and paperwork

Where the space above a drop ceiling is used as a return-air plenum, cable must be plenum rated. Landlords and building engineers often want drawings and a work window, and we schedule around business hours so the dining room or office keeps running.

Designing for Houston heat, storms and water

• Keep electronics out of the attic. Summer attic temperatures here run far past what amplifiers and streamers are designed for. Equipment lives in conditioned space, and closed cabinets get ventilation.
• Protect every conductor that comes from outside. Thunderstorms are frequent, so surge protection covers power, antenna or satellite coax and any Ethernet line that enters from another building, and outdoor masts and dishes are grounded.
• Use hardware that tolerates humidity. Outdoor speakers, stainless fasteners and drip loops on every exterior cable. Closer to Galveston Bay, in areas like Clear Lake, salt air makes corrosion resistance matter even more.
• Plan for water. In flood-prone neighborhoods, racks and subwoofers do not sit on ground-floor carpet, and cable enters equipment from above where practical.

Scheduling and pricing a job in a city this size

EVOTECH works out of Katy, so west Houston, including the Energy Corridor, Memorial, Spring Branch and Westchase, is close to home. Inside the Loop, the north side and the southeast take longer drives, and we group appointments by part of town to keep travel reasonable. Give us a call and we will confirm a date that works for your address. It helps to have ready any building rules or insurance requirements, photos of the walls involved, and the model numbers of equipment you already own.

What drives the cost

• Construction type: concrete, steel stud, plaster, shiplap or ordinary drywall over wood.
• Vertical distance and the number of floors a cable must climb.
• How much of the run can be concealed versus finished in raceway.
• Count of displays, sources and audio zones, and whether a control system ties them together.
• Commercial requirements such as plenum cable, after-hours labor and building-engineer coordination.
• Access time in towers, from freight elevators to parking.

Our on-site estimate turns these into an itemized quote, so nothing about the price is guesswork.
