Challenges We See in Older Homes
Plaster walls, irregular stud spacing, and narrow wall cavities are common in older homes. Here is what makes these installations different and how they get done right.
Plaster and Lath Walls
Many homes built before the 1960s have plaster and lath walls instead of modern drywall. Plaster is significantly harder and more brittle than drywall, which affects every aspect of a TV mounting or wiring project. Standard drywall anchors do not work in plaster — the material cracks instead of gripping. Toggle bolts and specialty plaster anchors are required, and even then, the best approach is always to anchor directly into the studs behind the plaster. Finding studs in plaster walls is also more difficult. Standard electronic stud finders struggle with the density and irregular thickness of plaster, often giving false readings. Experienced technicians use a combination of magnetic stud finders (which detect the nails holding the lath to the studs), small exploratory holes, and knowledge of typical stud patterns for the era of construction. Neighborhoods like Congress Park, Wash Park, Baker, and parts of Capitol Hill are full of plaster-walled homes. If your home was built before 1960 and you want a TV mounted or cables run through the walls, expect the process to take a bit longer than a standard drywall installation. The results are just as clean — it just requires different tools and techniques. Learn more about TV mounting services for different wall types.
Irregular Stud Spacing and Fire Blocks
Modern homes follow a consistent 16-inch stud spacing pattern. Older homes do not always follow this rule. Stud spacing in homes from the 1920s through the 1950s can vary from 14 to 24 inches, and the spacing may not be consistent even within the same wall. This matters for TV mounting because most mounting brackets are designed to attach to two studs spaced 16 inches apart. When the studs are at an irregular distance, the installation may require a mounting plate, a plywood backer, or a different bracket altogether to ensure secure attachment. Fire blocks add another layer of complexity. These are horizontal pieces of lumber nailed between studs at mid-height to slow the spread of fire through wall cavities. They serve an important safety function, but they also block the path for fishing cables through walls. When running Ethernet, HDMI, or speaker wire through an older home, your technician may need to drill through fire blocks or route cables around them — adding time and complexity to the job. None of these challenges are deal-breakers. They just require the right approach. A team that works in older homes regularly knows what to expect and carries the tools to handle it.
Narrow Wall Cavities and Limited Access
Older homes often have narrower wall cavities than modern construction. Where a contemporary 2x4 wall provides about 3.5 inches of cavity depth, some older homes used true 2-inch or even thinner framing, leaving very little space for routing cables or installing recessed electrical boxes. This is especially common in homes that have been renovated multiple times, where layers of additional material — furring strips, extra drywall over plaster, or rigid insulation — reduce the usable cavity space even further. Limited attic and crawl space access is another frequent challenge. Many older homes have low-pitch roofs with minimal attic clearance, making it difficult to route cables across the house through the attic. Basements in older homes may have finished ceilings that conceal the floor joists, removing another common cable routing path. When access is limited, creative routing becomes necessary. This might mean using exterior wall penetrations, running cables through closets or utility chases, or using surface-mounted raceways in areas where in-wall routing is not practical. The goal is always the cleanest possible result given the constraints of the home. Book a consultation to have your older home assessed before starting a project.
Getting Great Results in Any Home
The challenges of older homes are real, but they are not reasons to skip a TV mounting or wiring project. Thousands of homes in Park Hill, Highlands, Berkeley, Sunnyside, and other established neighborhoods have been successfully fitted with wall-mounted TVs, surround sound systems, and hardwired networks — it just takes the right expertise. The key is working with a team that has seen these wall types and construction methods before. Showing up to a plaster-walled 1920s bungalow with only drywall tools and standard anchors leads to frustration and poor results. Showing up with masonry bits, magnetic stud finders, plaster-rated hardware, and experience in these exact homes leads to a clean, secure installation that lasts. TV Solutions works in older homes every week. Every installation comes with transparent pricing — you will know the cost before work begins, even if the project involves plaster walls or complex routing — and the Lifetime Service Guarantee covers the workmanship for as long as the installation is in place. home network wiring or get started with a quote .
