Part one covered the mistakes that happen before a single board goes down. This second part covers the errors that show up once fitting actually starts, the details that separate a floor that looks genuinely professional from one that clearly wasn't.
1. Not staggering the boards properly
Laying boards with their end joints lined up in a regular, repeating pattern is one of the clearest giveaways of an inexperienced fit. Proper staggering offsets each row's joints by a meaningful distance, generally at least a third of a board's length, so the joints fall in a genuinely random-looking pattern rather than a repeating one. Watch out specifically for an H-pattern, where staggered joints accidentally line up every second or third row anyway, creating an unintentional repeating rhythm that's just as noticeable as no staggering at all.
2. Confusing the perimeter expansion gap with gaps between individual boards
These are two genuinely different things, and mixing them up is a common source of confusion. The expansion gap around the room's perimeter, between the flooring and the walls, is intentional and necessary, it gives the floor room to move with humidity changes, and it gets covered by skirting or beading once fitting is done. Gaps appearing between individual boards, by contrast, are a fitting error, usually caused by not tapping boards together firmly enough, or insufficient glue where it's required. If these do show up despite careful fitting, professional gap filling can correct them afterwards, but it's far better to get the tapping right the first time than to rely on a fix later.
3. Rushing or poorly executing cuts
Badly cut boards are one of the more avoidable mistakes on this list, and also one of the most visible once the floor is finished. Taking the time to measure precisely and cut cleanly, rather than rushing to keep up momentum, pays off directly in how tight and professional the finished joints look.
4. Skipping subfloor preparation and ending up with a noisy floor
An uneven or improperly prepared subfloor is one of the most common causes of a floor that creaks or squeaks once it's finished, an issue that's genuinely difficult to fix retroactively without lifting sections of the floor. Making sure the subfloor is level, secure, and free of loose spots before fitting begins avoids a problem that's far easier to prevent than to correct afterward.
5. Butting boards up against skirting instead of running underneath it
Stopping the flooring at the edge of existing skirting boards, rather than removing the skirting and running the floor underneath it, is a shortcut that's usually obvious to anyone who looks closely. Taking the time to lift the skirting, and trim door or window architraves where needed so boards can slide beneath them, makes a genuinely significant difference to how finished and professional the final result looks.
6. Not blending boards from multiple packs as you go
Even within the same product line, natural wood shows some colour and grain variation between different packs or batches. Working through one full pack before opening the next, rather than mixing boards from several packs as you fit them, risks creating visible blocks of slightly different tone across the room. Opening two or three packs at once and blending boards from each as you go gives a far more even, natural-looking spread of colour across the whole floor.
DIY Wood Flooring Fitting: Common Questions
What's the difference between an expansion gap and a gap between boards?
The expansion gap sits around the room's perimeter, between the flooring and the walls, and is intentional - it's later covered by skirting or beading. A gap between individual boards is a fitting error, usually from not tapping boards together firmly enough during installation.
How much should board joints be staggered by?
Generally at least a third of a board's length between adjoining rows, watching out specifically for an accidental repeating pattern (an H-pattern) where staggered joints still end up lining up every second or third row.
Why does a new wood floor sometimes creak after DIY installation?
This usually traces back to an uneven or improperly secured subfloor beneath the flooring. It's a genuinely difficult issue to fix once the floor is fully fitted, which is why proper subfloor preparation before fitting matters so much.
Is it really necessary to remove skirting boards rather than butt flooring against them?
It's not strictly necessary, but running the floor underneath skirting and trimmed architraves gives a noticeably more professional, finished look than stopping the boards at the skirting's edge.
