Having your stairs professionally renovated can cost €800–3,000 depending on the method and the type of staircase. Do it yourself and you only pay for materials: €150–800 for most renovation methods. A stair renovation is one of the most impactful upgrades you can make to your home — it transforms the entire hallway — and is well within reach of a competent DIYer over a weekend. In this article we compare all the options: painting, overlay treads, and full replacement.
What does stair renovation cost? DIY vs. hiring a tradesperson
Cost overview
| Method | Material costs | Labour costs (tradesperson) | Total DIY | Total with tradesperson |
|---|---|---|---|---|
| Painting stairs | €50–120 | €200–400 | €50–120 | €250–520 |
| Overlay treads (wood) | €300–700 | €400–800 | €300–700 | €700–1,500 |
| Overlay treads (composite) | €400–900 | €400–800 | €400–900 | €800–1,700 |
| Completely new staircase | €800–2,500 | €500–1,500 | €800–2,500 | €1,300–4,000 |
| Carpet covering | €100–300 | €150–300 | €100–300 | €250–600 |
Example calculation: staircase with 14 treads, oak overlay treads
- DIY: approx. €450–600
- Tradesperson: approx. €1,100–1,600
- Saving: €650–1,000
When is DIY worth it?
Painting and carpeting are the simplest DIY options. Fitting overlay treads is slightly more technical (cutting to size, gluing and screwing) but very achievable with basic tools. Fitting a completely new staircase requires considerably more skill and is better left to a joiner.
Which renovation method suits you?
| Method | Suitable when… | Advantages | Disadvantages |
|---|---|---|---|
| Painting | Staircase is structurally sound | Cheapest, dramatic colour change | Wears faster, needs repeating |
| Overlay treads | Old treads worn but structure OK | Quick transformation, durable | Staircase becomes slightly higher |
| Full replacement | Structure worn or complete redesign desired | Most comprehensive solution | Most expensive option |
| Carpet covering | Quick result, soft, sound dampening | Cheap, warm | Wears faster, harder to clean |
Overlay treads: what are the options?
| Type | Price per tread | Appearance | Durability |
|---|---|---|---|
| MDF (painted) | €15–25 | Crisp, modern | Moderate (moisture-sensitive) |
| Softwood (pine) | €18–30 | Classic, warm | Good |
| Hardwood (oak, beech) | €35–65 | Premium, timeless | Excellent |
| Bamboo | €30–55 | Modern, sustainable | Excellent |
| Composite | €40–80 | Modern | Excellent |
Materials list (overlay treads, staircase with 14 treads)
| Material | Quantity | Approximate price |
|---|---|---|
| Overlay treads (width to measure) | 14 pieces | €490–910 |
| Risers (optional, MDF or wood) | 14 pieces | €70–150 |
| Construction adhesive (PU or MS-polymer) | 3–4 tubes | €30–50 |
| Wood screws (countersunk) | 1 box | €10 |
| Dowels / pull connectors | 1 pack | €10–15 |
| Sandpaper (P80, P120, P180) | 5 sheets | €8–12 |
| Wood stain or varnish | 1 litre | €20–35 |
| Sealant / trim profile (bottom transition) | 15 m | €20–40 |
Step-by-step guide: renovating stairs with overlay treads
Step 1 — Clean and inspect the old treads
Remove any carpet, stair runner, or old paint from the existing treads. Check that the supporting structure (stringers and balusters) is solid. Fix any loose balusters with wood screws or construction adhesive. Remove any protruding nails and tacks.
Step 2 — Measure up and order treads
Measure each tread individually (width and depth). Treads are rarely exactly the same size. The overlay tread must cover the existing tread completely, including the nosing (the protruding front edge). Order to size from a timber merchant or builders’ merchant. Allow the treads to acclimatise in the room for 48 hours before fitting.
Step 3 — Cut treads to size
Cut the treads to the correct size. Use a mitre saw or circular saw for straight, clean cuts. Sand all cut edges smooth (P80 → P120 → P180).
Step 4 — Glue and screw treads in place
Apply construction adhesive to the existing tread (zigzag pattern, not too thick). Press the overlay tread into position and screw from the front with countersunk screws. Cover the screw heads with wood filler or wooden plugs. Start at the bottom of the staircase and work upwards.
Step 5 — Fit risers (optional)
Fit the new risers (the front face of the step, the vertical section). This completes the renovation and hides the joints. Glue and nail if necessary.
Step 6 — Finishing and varnish / stain
Fill any holes and screw heads with wood filler. Sand smooth again. Apply a primer coat to the treads, then two or three coats of topcoat varnish or stain. Allow each coat to dry completely before applying the next. Use an anti-slip varnish for the top coat for extra safety.
Painting stairs: quick guide
- Sand treads with P80 and P120
- Degrease with acetone or degreaser
- Apply one coat of primer
- Apply two coats of floor paint or specialist stair paint (designed for heavy wear)
- Allow each coat to dry for 24 hours before using the stairs again
Common mistakes
| Mistake | Consequence | Solution |
|---|---|---|
| Not acclimatising treads | Shrinking or swelling after fitting | Leave in the room for 48 hours |
| Only gluing, not screwing | Treads work loose with use | Always glue AND screw |
| Using the wrong paint | Paint wears off quickly | Use specialist stair paint or floor varnish |
| Not measuring each tread | Treads don’t fit | Measure each tread individually |
| Applying varnish too soon | Bubbling and poor adhesion | Wait at least 24 hours per coat |
Conclusion
Stair renovation is a DIY project you can tackle in a single weekend and give your entire home a new lease of life. For most staircases, overlay treads offer the best balance of results, durability, and cost. Painting is the quickest and cheapest option but requires the right paint and thorough surface preparation. With a budget of €300–700 you can achieve a result that looks professionally done.
