Mounting a television on the wall seems straightforward enough, but after helping dozens of mates with their botched attempts over the years, I can tell you it’s anything but simple. The number of times I’ve seen wonky tellies, cables dangling everywhere, or worse — holes in the wall where someone’s pride and joy came crashing down — well, let’s just say it’s made me a bit of an expert on what NOT to do.
Professional installers have shared their hard-earned wisdom with me, and I’ve picked up quite a few tricks myself. These aren’t just theoretical tips either; they’re battle-tested solutions that’ll save you from the headaches, arguments with your partner, and potential disasters that come with DIY TV mounting gone wrong.
Finding the Perfect Spot Isn’t Just About Aesthetics
Most people think mounting location is purely about what looks good, but professionals know better. The ideal viewing height puts the centre of your screen at eye level when you’re seated — typically between 107-122cm from the floor for most living rooms. I learnt this the hard way when I mounted my first TV so high up the wall that watching anything longer than 30 minutes gave me a proper crick in the neck.
Lighting considerations matter enormously too. Windows, lamps, and overhead lighting can create glare that makes viewing impossible during certain times of day. Professional installers always check the room at different times to identify potential reflection issues. They’ll often recommend positions that might not be your first choice but will give you the best viewing experience year-round.
Room acoustics play a role as well. Mounting your TV too close to a corner can muffle sound, whilst positioning it opposite hard surfaces might create echo. These subtleties separate amateur installations from professional ones.
Wall Types Determine Everything
Here’s where things get properly technical, and frankly, where most DIY attempts go sideways. Professionals use a stud finder religiously, but they also know that not all stud finders are created equal. The cheap ones from the hardware store? They’re notoriously unreliable, especially on textured walls or older homes with irregular framing.
Plasterboard walls require mounting into wooden studs for anything heavier than a small picture frame. The studs are typically spaced 40cm or 60cm apart in the UK, but older homes can be completely irregular. Professional installers often use a small finishing nail to probe suspected stud locations rather than trusting their equipment entirely.
Brick or concrete walls need masonry anchors, and this is where amateur installations often fail spectacularly. The wrong drill bit, inadequate anchor size, or poor drilling technique can leave you with a useless hole and a very expensive repair job. I’ve seen people use standard wall plugs for a 40kg television — it’s like using sellotape to hang a painting.
Choosing the Right Mount Makes All the Difference
Mount selection isn’t just about weight capacity, though that’s obviously crucial. Professional installers consider the specific use case: will you need to adjust the viewing angle regularly? Do you want to occasionally pull the TV away from the wall for cable access? Are you mounting in a corner where you’ll need to angle the screen?
Fixed mounts are the strongest and most affordable, but they offer zero flexibility once installed. Tilting mounts allow up and down adjustment — essential if you’re mounting higher than ideal viewing height. Full-motion mounts provide maximum flexibility but they’re also the most complex to install properly and require the most robust wall attachment.
Weight ratings on mounts should be taken seriously, but professionals also consider the lever effect. A 32″ TV on a full-motion mount extended from the wall creates significantly more stress on the mounting points than the same TV on a fixed mount. It’s basic physics, but it catches people out constantly.
VESA compatibility is another crucial factor. Most modern TVs follow VESA standards, but the mounting hole pattern varies significantly between sizes and manufacturers. Double-check your TV’s specifications before purchasing any mount — I’ve seen too many frustrated homeowners discover their new mount doesn’t fit their telly.
Cable Management Separates Amateurs From Professionals
Nothing screams “DIY disaster” quite like a beautifully mounted TV with cables snaking down the wall like electronic spaghetti. Professional installations always include proper cable management, and it’s not just about aesthetics — it’s about functionality and safety too.
In-wall cable routing is the gold standard, but it requires careful planning and often professional electrical work. You can’t just shove any old cable inside the wall cavity; power cables need to be run through proper conduit, and there are building regulations to consider. Many DIY enthusiasts don’t realise that running extension leads through walls violates electrical codes.
External cable management systems — plastic channels, cord covers, and cable raceways — offer a compromise solution. They’re not as elegant as in-wall routing, but when done properly, they can look quite professional. The key is planning the route carefully and using appropriately sized channels.
Professionals always leave service loops behind the TV. These extra lengths of cable allow for future adjustments without having to rewire everything. It’s a small detail that makes a huge difference if you ever need to move or service your installation.
Getting Everything Level and Secure
A wonky TV mount is like a crooked picture frame — once you notice it, you can’t unsee it. Professional installers use multiple methods to ensure perfect alignment, starting with a quality spirit level (not the dodgy app on your phone).
The mounting bracket attachment to the wall needs to be perfectly level, but here’s what catches people out: the TV attachment points also need to be perfectly aligned. Many mounting systems have adjustment screws that allow fine-tuning, but these need to be set correctly during installation.
Torque specifications matter more than most people realise. Under-tightened bolts can work loose over time, whilst over-tightening can strip threads or crack mounting points. Professional installers often use torque wrenches for critical connections, especially on expensive displays.
Security features like safety locks or anti-theft bolts might seem unnecessary for home installations, but they prevent accidental dislodging. I’ve seen curious children or pets accidentally knock TVs off their mounts because there was no secondary security mechanism.
Power and Signal Considerations
Modern TVs need more than just a power connection. HDMI cables, ethernet connections, antenna leads — the list goes on. Professional installers plan for current needs whilst anticipating future requirements. Nothing’s more frustrating than completing a beautiful installation only to discover you need additional connections that require tearing everything apart.
HDMI cable quality matters, especially for longer runs or high-resolution content. Cheap cables from the pound shop might work for short distances, but they often fail with 4K content or longer cable runs. Professional-grade cables cost more upfront but save headaches later.
Power outlet placement is crucial but often overlooked. The outlet needs to be positioned where it won’t interfere with the mount whilst remaining easily accessible for occasional unplugging. Many people discover too late that their existing outlet is in completely the wrong place.
Testing and Final Adjustments
Professional TV installers never consider a job complete until they’ve thoroughly tested the installation. This means checking that the mount is secure, all connections work properly, and the viewing experience meets expectations from various seating positions.
Adjustment mechanisms should be tested even if you don’t plan to use them immediately. Tilt and swivel functions can seize up over time if never used, and it’s better to discover problems whilst the installer is still present.
Picture quality testing involves checking for signal issues, colour accuracy, and any interference from nearby electronics. Sometimes the mounting process can affect antenna reception or create interference with other devices.
Safety First, Always
Professional installers take safety seriously because they’ve seen what happens when things go wrong. Proper protective equipment, correct lifting techniques, and appropriate tools aren’t optional extras — they’re essential for preventing injuries and property damage.
Electrical safety is paramount, especially when running new cables or installing additional outlets. Turn off circuit breakers before doing any electrical work, and don’t hesitate to call a qualified electrician if you’re unsure about anything.
Structural considerations matter too. Load-bearing walls, hidden utilities, and building regulations all play a role in safe installations. Professional installers know when to stop and seek expert advice rather than pushing ahead with questionable mounting solutions.
Final Thoughts
After witnessing countless DIY mounting disasters and seeing the difference professional installation makes, I’ve become a bit of a stickler for doing things properly. Yes, it costs more upfront to hire professionals or invest in quality tools and materials, but the peace of mind is worth every penny.
The most important lesson I’ve learnt is knowing your limitations. There’s no shame in calling professionals for complex installations or when you encounter unexpected problems. A botched DIY job often costs more to fix than hiring experts from the start.
Take your time, plan thoroughly, and don’t cut corners on safety or quality. Your TV mounting project should enhance your viewing experience, not create ongoing headaches or safety hazards.
