Three installer fixes with maker guidance for skirting with laminate

Leave a gap of around 10 mm between the laminate and the wall, then fit skirting over the finished floor to cover it. This approach, recommended in Orac’s own installer guidance, protects the laminate’s natural expansion and contraction while giving a clean, low-maintenance finish. The steps below walk through measuring, cutting, fixing and sealing, along with the fixes we turn to when a floor refuses to sit flat.

TL;DR:

• Skirting should be installed roughly 10 mm above the laminate to allow for floor expansion and contraction, covering the gap for a clean finish.
• Fitting skirting over laminate is quicker and hides the expansion gap, but removal and refitting provide a tighter wall flush on uneven floors.
• Use impact-resistant Duropolymer skirting with flexible sealants for gaps, and scribe or pack boards to follow floor undulations for best results.
• For uneven floors, fitting profiles with a hollow-back cavity can hide cables and accommodate minor slopes or dips.
• Proper fixing and a visible reveal improve long-term stability, preventing cracking or lifting caused by floor movement over time.

Fitting over, removing and refitting, or using a shadow gap

Most homes call for one of three approaches, and the right one depends on your walls, your existing skirting and the finish you want.

Fitting new skirting over the laminate is the quickest route and hides the expansion gap in one move. It suits reasonably flat walls and standard skirting heights, and it is the method Orac’s installation instructions are built around.

Removing and refitting the existing skirting gives the truest flush finish against the wall, but it takes longer and usually means patching plaster where old fixings pulled away. This route earns its extra effort when floors are uneven or when you are changing to a different skirting profile anyway.

A shadow gap or bead offers a minimalist alternative: a shallow reveal runs along the floor line instead of a visible skirting edge to conceal the expansion joint behind a 10 mm shadow gap detail. It works best where a slim reveal fits the room’s style and where floors are genuinely level.

Before deciding, weigh up:

• How level the floor and walls actually are, checked with a spirit level at several points.
• Whether the existing skirting is worth keeping or has already been damaged by damp or knocks.
• The finish you want, from traditional profiles to a minimal shadow line.
• Your budget and timescale, since removal and refitting takes longer than fitting over.

Step-by-step: measuring, cutting and fixing skirting to laminate

Getting the sequence right matters more than working quickly. Here is the order that keeps a room looking consistent even when the floor underneath is not.

1. Lay the laminate fully first, then find the highest point of the finished floor and mark a level reference line around the room from there.
2. Leave an expansion gap of roughly 8 to 10 mm between the laminate and the wall, checking it at several points along each run, as Orac recommends.
3. Measure each wall run and cut skirting to length, using mitres for external corners and a coped cut for internal corners so the profile shape sits flush against its neighbour.
4. Apply adhesive along the back of the skirting first for Duropolymer profiles, positioning the board before adding any supplementary fixings, then allow it to cure before handling further.
5. Where the floor dips or rises, scribe the bottom edge of the skirting to follow it, use packers behind the board, or switch to a hollow-back profile that flexes over minor undulations.

Pro Tip: Run a long batten along your level line before cutting a single piece of skirting: it flags awkward high or low spots early, saving you from cutting boards twice.

For tighter internal corners, coping (cutting the profile to match the face of the adjoining board) gives a neater joint than a mitre, particularly on walls that are not quite square.

Tools and materials that work with laminate

Duropolymer skirting, the material behind Orac Decor’s profiles, suits laminate installations because it is lightweight, resistant to impact and water resistant, according to Orac’s technical documentation. That combination matters near skirting boards, which take knocks from vacuum cleaners and furniture more than any other trim in the room.

For fixing, a DecoFix Power adhesive holds most runs on its own, with mechanical fixings added only where a wall is uneven or particularly absorbent. DecoFiller closes joints and mitres neatly once the adhesive has cured.

Before you start, gather:

• A mitre saw or mitre box for clean angled cuts.
• A scribing tool and spirit level for marking uneven walls and floors.
• Packers to pack out gaps behind the skirting where the wall bows.
• A filler knife and caulk gun for DecoFiller and flexible sealant.

Getting the finish right: painting, filling and hiding cables

Pre-primed Duropolymer skirting can be overpainted once the adhesive and filler have cured, generally after 24 hours according to Orac’s guidance, which also notes that many profiles come pre-finished in RAL9003 for rooms that need no further painting at all.

Use DecoFiller at mitred corners and along butt joints, but never across the expansion gap itself: that joint needs to keep moving with the floor, so a flexible sealant is the right choice there, not rigid filler.

Where a renovation calls for tidier cable runs, some skirting profiles include a hollow-back cavity that hides cables behind the board rather than under the floor, worth specifying before you order if you know cables need routing along that wall.

• Fill mitres and butt joints with DecoFiller once the adhesive has fully cured.
• Seal the expansion gap with a flexible sealant, never a rigid filler.
• Choose a hollow-back profile early if you need to hide cables along that run.
• Check sealant lines each autumn and spring, when seasonal humidity shifts the floor.

Common problems and installer-proven fixes

A visible gap under skirting is the complaint we hear most often, and it usually has a straightforward fix. Depending on the cause, we reach for packers, a bead, a hollow-back profile, or a scribed skirting board, matching the fix to how uneven the floor actually is rather than guessing.

Rocking or squeaking skirting almost always means the board was fixed before the wall or floor had settled, or that fixings missed solid backing. Refitting with adhesive plus a mechanical fixing into a stud or masonry usually cures it for good.

• Pack behind the board with thin shims where the wall dips inward.
• Fit a bead along the floor line to bridge a wider, uneven gap.
• Swap to a hollow-back profile if the gap varies significantly along one wall.
• Scribe the skirting itself when the floor has a consistent slope rather than isolated dips.

Pro Tip: In our experience, most rework comes from fixing skirting straight onto an unsettled wall. We’ve found that letting a freshly plastered wall dry fully before fitting saves a callback within the year. If a wall is significantly out of true or a floor has more than a few millimetres of fall across a run, that is usually a job worth handing to a professional installer rather than fighting with packers alone.

Why a small reveal and proper fixing beats a quick cosmetic fix

Tradespeople lean towards a visible reveal and solid fixing because it respects how laminate behaves over time: it expands, contracts, and occasionally needs access beneath the skirting for repairs. A tight, glued-down join might look sharper on day one, but it tends to crack or lift within a season once the floor moves.

Cutting that corner rarely saves time overall. It just moves the work to next year, when the skirting has to come off again anyway. If your walls or floors are giving you trouble, our skirting range and installer network are there to take that decision off your hands.

FAQ

Should skirting boards touch laminate flooring?

No, skirting should sit just clear of the laminate rather than pressing against it. Leaving roughly 10 mm for expansion lets the floor move with temperature and humidity, and the skirting simply covers that gap from view.

How do you seal laminate flooring to a skirting board?

Use a flexible sealant along the expansion gap rather than a rigid filler, since the joint needs to keep moving with the floor. Rigid fillers such as DecoFiller are fine at skirting joints and mitres, but not across the gap where laminate meets the wall.

Do you need to remove skirting boards to lay laminate flooring?

Not always. Fitting new or existing skirting over the finished laminate is often quicker and still gives a neat result, though removing and refitting gives the truest flush finish, particularly on uneven floors or when swapping to a new profile.

Should laminate flooring be laid under skirting or beading?

Laminate should stop short of the wall, with the skirting or a bead sitting over the top to hide the expansion gap rather than the flooring running underneath it. This is the approach Orac’s own guidance describes, and it keeps the gap accessible if the floor needs adjusting later.
