Floor threshold installation in Warsaw — clean transitions between flooring types

A threshold strip is one of those things nobody notices until it is missing. Without it, the joint between laminate and tiles looks rough, edges lift up, and dirt collects in the gap. In new builds around Bialoleka and renovated flats in Bemowo the situation is the same: two different floor materials meet in a doorway and nothing connects them. That is exactly what we fix.

How much does it cost

The price depends on the profile type, the width of the opening and the height difference between surfaces. A flat aluminium strip costs less than a multi-level compensating profile. Current rates for all flooring work are in the table below. Fixings are included in the price; threshold strips are supplied by the client.

How the installation works

1. Inspecting the joint: measuring the opening width and the height difference between the two floor surfaces.
2. Choosing the right profile: flat, T-shaped, multi-level or flexible — depending on the situation.
3. Cutting the strip to size — hacksaw or angle grinder for aluminium, utility knife for PVC.
4. Marking drill points and drilling into the subfloor (for screw-down thresholds). If underfloor heating is present — adhesive or self-stick profiles only.
5. Inserting wall plugs and screwing the strip down. For concealed fixings — the mounting rail goes in first, then the decorative cover snaps on top.
6. Final check: the strip must be firm, and its edges must not catch the door when it swings.

Common mistakes

• Using a flat profile where the height difference is 5 mm or more — it cannot press the material down, edges stick up.
• Drilling into a floor with underfloor heating — damages the heating cable, and the repair costs far more than the threshold.
• Picking the wrong colour — ‘oak-effect’ aluminium next to grey laminate looks odd.
• Cutting the strip too short — gaps appear on each side, collecting dirt and debris.
• Not leaving an expansion gap — the laminate pushes against the strip and buckles.
• Sticking a self-adhesive strip to a dusty floor — it peels off within a week.

What to prepare before the visit

• Buy threshold strips of the correct type and colour — measure the width of every doorway in advance.
• Both floor surfaces must be fully laid before threshold installation.
• Check whether there is underfloor heating in the joint area — this determines how the strip is fixed.
• Clear the doorways of furniture and belongings.
• If a door already scrapes the floor — let us know; the door leaf may need trimming after the threshold is fitted.

A real case from Warsaw

We were called to a two-bedroom flat in Bialoleka. The owners had laid laminate in the bedrooms and living room, tiles in the hallway and kitchen. Four doorways with no thresholds, height differences ranging from 3 to 7 mm. We selected multi-level aluminium profiles colour-matched to the laminate. The kitchen had underfloor heating, so we used adhesive mounting there — no drilling. The other three were fitted with concealed screw fixings. The whole job took about ninety minutes. Doors close freely, joints look neat, nothing catches.

Frequently asked questions

Which threshold works between laminate and tiles?
If both surfaces are level — a flat or T-shaped profile. If there is a height difference — a multi-level strip. Material: aluminium lasts the longest; PVC is cheaper but wears out faster.

Can I skip the threshold altogether?
You can, if both materials are the same thickness and the joint line is straight. In that case a cork expansion strip or silicone sealant works. But a threshold is more reliable — it covers the gap and protects the edges from chipping.

What about underfloor heating?
No drilling. We use a self-adhesive profile or mounting adhesive. Before installation we always confirm where the heating elements run.

The threshold makes the door stick — what now?
We trim the bottom of the door leaf. It is a separate service, but we can do it during the same visit.
