Most media wall builds take between 2 and 5 days on site, depending on the size, complexity and finish involved. This guide walks through each stage of the build, explains what adds time, and tells you what to expect on each day of the process.
Quick answer
- Standard TV media wall (no fireplace): typically 2–3 days on site.
- Media wall with integrated fireplace: typically 3–5 days on site.
- Larger or more complex builds (full alcove units, custom joinery, ceiling detail) can extend this further — we’ll confirm the expected duration when we quote.
- Drying time adds lead time beyond the on-site build — plaster and certain finishes need time to cure before decoration can be completed.
- Planning is the longest part — most of the work happens before the build starts, not during it.
Why timelines vary so much
When people ask how long a media wall takes, they often expect a simple answer. The honest answer is: it depends on the scope of the job. A basic stud wall with hidden wiring and a flush-mounted TV is a very different project to a floor-to-ceiling media wall with an integrated fireplace, LED lighting, alcove storage and a bespoke painted finish.
That said, most builds in South Yorkshire homes fall within a predictable range, and understanding what affects the timeline helps you plan your project and manage expectations.
The media wall build timeline: stage by stage
Here’s how a typical build breaks down across the days on site.
Day 1: Stud work and framework
The first day is almost always about the frame. We build out the stud wall structure — typically using metal stud and track — and create the recess for the TV. This stage also involves planning the internal wiring runs and any boxing-in for cables.
If the build includes a fireplace, the recess for the fire unit is also formed on day one. The fireplace framework is usually the most complex structural part of the build, particularly if there are specific clearance requirements or if the fire unit is being inset into a deeper recess.
Day 2: Boarding and first fix electrics
Once the frame is up, we board the structure. This is usually plasterboard or a combination of moisture-resistant board and plasterboard depending on the finish required. All wiring for sockets, TV connections, LED lighting and fireplace supply runs during this stage before the board goes on.
First fix electrics — getting cables in the right positions within the wall before it’s closed up — is one of the stages where experience really matters. Getting the socket and cable positions right before the board goes on avoids chasing and patching later.
Day 3: Plastering or skim coat
Most media walls receive a plaster skim coat to achieve a smooth, professional finish. Plastering itself is relatively quick — usually a day — but the plaster needs adequate drying time before decoration can begin. In typical South Yorkshire conditions, this is usually 3–7 days depending on ventilation and temperature.
Alternatively, some builds use a dry-lining finish (taped and filled joints) rather than a full skim coat. This can reduce drying time but requires a very high standard of filling work to look right once painted.
Day 4 onwards: Finishing, joinery and second fix
Once the surface is cured, finishing work continues. This includes:
- Fitting socket plates and media plates
- Fitting LED lighting channels and profiles
- Installing shelving, alcove units or joinery elements
- Commissioning and testing the fireplace (where applicable)
- TV mounting, connection routing and cable management
Decoration
Decoration — painting, panelling or cladding — is usually the final stage. Depending on the specification, this may be carried out by the same team or coordinated with a decorator. Either way, it follows on from the plaster cure time.
What makes a build take longer?
Understanding what adds time helps you make informed decisions during the planning stage — and avoids surprises on site.
Integrated fireplaces
A media wall with an integrated fireplace adds at least a day to the build in most cases. The fire recess, the electrical supply, the clearance requirements and the final commissioning of the unit all take time. If the fireplace involves any gas work (for a gas or flueless model), this needs to be coordinated with a Gas Safe engineer — which adds planning time rather than necessarily on-site time.
Storage and alcove units
If the build includes floor-to-ceiling alcove units, bespoke joinery or built-in storage, expect additional days. Custom joinery elements are often pre-fabricated off-site and then fitted on-site — the fitting itself can add a day or more depending on the complexity of the design.
LED lighting
Integrated LED lighting — particularly if it includes multiple zones, colour-changing strips or downlights in the ceiling above the wall — adds time at the wiring and commissioning stage. It’s worth finalising your lighting specification before the first fix stage to avoid revisiting the framework.
Larger wall widths
A media wall that spans the full width of a room (5–6 metres) takes proportionally longer than a standard 3–4 metre feature wall. More framework, more boarding, more finishing — all of which adds time.
| Build type | Typical on-site time |
|---|---|
| TV media wall (no fire, standard width) | 2–3 days |
| TV media wall with integrated fireplace | 3–5 days |
| Full-width wall with alcove units and lighting | 4–6 days |
| Bespoke floor-to-ceiling joinery build | 5–7+ days |
Timelines are indicative. We confirm exact duration at the quoting stage based on your specific design and finish.
Planning your project: total timeline from enquiry to completion
The on-site build is just one part of the overall project. Here’s a typical timeline from first contact to completed media wall.
Week 1–2: Enquiry, photos and quote
The quickest way to get a quote is to send a photo of your wall and tell us your TV size and whether you want a fire. We’ll come back with realistic pricing and a clear idea of what’s involved. If you’d like a home visit to finalise the design, we can usually schedule this within a week or two.
Week 2–4: Design finalisation and materials ordering
Once you’re happy with the quote and design, we agree on the specification — socket positions, lighting layout, fireplace model (if applicable), finish and colours. Materials are ordered and the install date is confirmed. Lead time for certain fireplace models can affect this stage.
Build week: On-site install
The on-site build follows the stage-by-stage process described above. We work cleanly and tidily — the room will be unavailable during the build, but we contain the disruption as much as possible.
Post-build: Drying and decoration
After plastering, the wall needs time to dry fully before painting. In good conditions, this is 3–5 days. We recommend keeping the room well ventilated and avoiding heating it artificially — slow drying is better than fast drying for a good final result.
Common questions about media wall timelines
Here are a few things customers regularly ask when planning their project.
Can we use the room during the build?
During active building work, the room will need to be clear. Dust and debris are part of the process, and we protect flooring and furniture as standard — but access to the room during working hours won’t be possible. For most builds, this is a 2–5 day disruption.
Can the TV be mounted on the day of the build?
The TV mount can be fitted during the build. The TV itself should be connected and positioned after the full build is complete — ideally after decoration, once all the finishes are in place. Mounting a TV before painting risks marks and damage to the screen.
What if unexpected issues come up?
Occasionally builds encounter surprises — particularly in older homes where the existing wall structure isn’t as straightforward as expected. We always flag this as early as possible and discuss options before proceeding. In most cases, delays from unforeseen issues are a matter of hours, not days.
FAQs
Do I need to do anything to prepare the room before the build?
We recommend clearing the room as much as possible before we arrive. Remove furniture, pictures and anything on the wall that will be built against. If the existing wall has wallpaper, let us know — we may need to prepare the surface before building out from it.
How long after plastering can I decorate?
Allow at least 3–5 days in warm, well-ventilated conditions. In cooler or less ventilated rooms, 7–10 days is safer. New plaster should feel completely dry to the touch — not just surface-dry — before you apply a mist coat. Rushing this stage leads to peeling paint.
Does a fireplace installation add to the build time?
Yes — typically an extra 1–2 days. The recess, electrical supply, commissioning and testing of the fire unit all take time. If there’s any gas work involved, this is coordinated separately with a Gas Safe engineer and scheduled around the main build.
Can you work on weekends or evenings to minimise disruption?
Occasionally this can be accommodated, particularly for elements of the build that don’t involve significant noise or dust. Get in touch and we can discuss what’s possible for your specific job.
Will I need to arrange for an electrician separately?
For most media wall builds, the electrical work is first-fix only — routing cables, positioning sockets and connections. The second-fix (fitting plates, commissioning) is part of our process. For more complex electrical work, we can advise on the appropriate trades to coordinate.
