Decking installation in Prague typically costs between 1 800 and 5 500 Kč per square metre including materials and labour, depending on the type of decking, subframe requirements, and the size of your outdoor space. Whether you're building a garden terrace at a family house in Černošice or adding a small deck to a Prague 5 courtyard, this guide breaks down everything you need to know about costs, materials, and hiring the right installer in 2026.
Decking Installation Cost in Prague: 2026 Price Ranges
Prices for decking in Prague vary significantly based on the material you choose, the condition of the ground underneath, and how complex the design is. Here are the typical ranges you can expect in 2026:
- Pressure-treated softwood (pine/spruce): 1 800–2 800 Kč/m² installed
- Thermowood (thermally modified timber): 2 500–3 800 Kč/m²installed
- Exotic hardwood (bangkirai, ipe, massaranduba): 3 500–5 500 Kč/m² installed
- WPC composite decking: 2 800–4 500 Kč/m² installed
These figures include the decking boards, subframe (typically aluminium or treated timber joists), fasteners, and labour. They do not include groundwork such as laying a concrete slab or gravel base, which can add 500–1 500 Kč/m² if you're starting from bare soil.
What drives the price up or down?
Several factors push your final bill above or below those averages:
- Ground preparation: If your garden already has a flat, stable patio or concrete pad, the installer can build the subframe directly on it. If the ground is sloped or soft, you'll need levelling work, drainage, and possibly a concrete footing — adding 30–50 % to the base cost.
- Deck size: Larger decks (30 m²+) often come with a lower per-square-metre rate because the setup and transport costs are spread across more area.
- Shape and features: Straight rectangular decks are cheapest. L-shapes, curves, built-in planters, stairs, or integrated lighting all add complexity and labour time.
- Height and railings: A raised deck more than 60 cm off the ground needs railings (zábradlí), which typically cost 1 500–3 500 Kč per running metre depending on material.
- Access: If materials have to be carried through a narrow Prague apartment hallway or down steep garden steps, expect a surcharge for the extra labour.
Wood vs. Composite Decking: Which Is Better for Prague?
This is the first big decision, and Prague's continental climate — hot summers, freezing winters, and plenty of rain — makes it an important one.
Treated softwood (smrk, borovice)
The most affordable option. Czech-sourced pressure-treated pine or spruce is widely available and works well for budget builds. The downside: it needs re-oiling or staining every 1–2 years to resist the Prague weather, and even with treatment, softwood typically lasts 10–15 years before boards need replacing. It can also become slippery when wet unless you choose profiled (ribbed) boards.
Thermowood
Thermally modified timber (often Finnish pine or ash processed at high temperatures) is popular in Czech Republic for good reason. It resists moisture and rot far better than standard softwood, lasts 20–25 years, and has a warm natural appearance. It still benefits from annual oiling but is more forgiving if you skip a year. It's the sweet spot between cost and durability for most Prague homeowners.
Exotic hardwood
Bangkirai and ipe are incredibly dense and durable — expect 25–30+ years of life. They handle freeze-thaw cycles well. However, they're expensive, heavy (which can affect subframe requirements), and harder to work with, meaning higher labour costs. They also grey over time without regular oiling, which is purely cosmetic but bothers some people.
WPC composite
Wood-plastic composite (WPC) boards are increasingly popular in Prague suburbs. They're essentially maintenance-free — no oiling, no staining, no sanding. Modern composites look remarkably like real wood and handle Czech winters without cracking. The trade-off is a higher upfront cost and the fact that some people simply prefer the feel of real timber underfoot. Also note that composite decks can get very hot in direct summer sun.
What Does Decking Installation Actually Involve?
Understanding the process helps you evaluate quotes and spot installers who are cutting corners. A proper decking installation in Prague follows these steps:
- Site assessment: The installer visits to measure the area, check ground conditions, drainage, and access. Any reputable tradesperson will insist on this before quoting.
- Ground preparation: Depending on the site, this might mean laying a weed membrane and gravel bed, pouring concrete pads, or levelling existing paving.
- Subframe construction: Aluminium or treated timber joists are laid on adjustable pedestals or concrete supports, levelled precisely. This is the skeleton of your deck — skimping here leads to bouncy, creaky boards within a year.
- Board installation: Decking boards are fixed to the subframe with hidden clips (for a clean look) or screwed from the top. Expansion gaps are left between boards and at edges to account for seasonal movement.
- Finishing: Edge trims, fascia boards, stairs, and railings are installed. If using timber, the first coat of oil or stain is applied.
A typical 20 m² deck takes 2–4 working days to complete, assuming the ground is already prepared. Add 1–3 days for groundwork if needed.
Do You Need a Permit for Decking in Prague?
For most garden-level decks — meaning a simple platform sitting on the ground or raised up to about 30–40 cm — you typically don't need a building permit (stavební povolení) in Czech Republic. However, the rules change if:
- The deck is raised significantly above ground level (creating a usable space underneath)
- It's attached to the building structure and changes the building's footprint
- Your property is in a heritage zone (památková zóna), which covers large parts of central Prague
- You live in a housing development with an SVJ (společenství vlastníků jednotek) — the owners' association may need to approve external modifications
For anything beyond a straightforward ground-level garden deck, it's worth checking with your local stavební úřad (building authority) or asking your installer. Many experienced deck builders in Prague know the local rules well and can advise during the site assessment.
How to Find a Good Deck Installer in Prague
Finding a skilled decking installer — especially one who speaks English — can be challenging for expats. Here's a practical approach:
What to look for
- Experience with your chosen material: Composite and hardwood installation techniques differ significantly from softwood. Ask specifically about the material you want.
- A valid IČO: Every legitimate Czech tradesperson or company has a company registration number (IČO). You can verify it on ares.gov.cz, the official Czech business register. This confirms they're a registered business.
- Portfolio of past work: Ask for photos of completed decks, ideally in the Prague area. Even better if you can visit a finished project in person.
- Written quote with itemised costs: Materials, labour, groundwork, and VAT (DPH, currently 21 %) should all be broken out separately. If someone gives you a single lump number with no breakdown, keep looking.
- Willingness to sign a smlouva o dílo: This is the standard Czech work contract. It protects both you and the tradesperson by specifying scope, timeline, price, and warranty terms.
Questions to ask before hiring
- What subframe system do you recommend for my site, and why?
- How do you handle drainage under the deck?
- What guarantee do you offer on the installation (not just the materials)?
- Can you provide references from recent clients?
- What's the timeline, and will you be on-site personally or send a crew?
Get multiple quotes
Always get at least three quotes. Prices for the same 20 m² deck in Prague can vary by 30–50 % between installers, and the cheapest option isn't always the worst — nor is the most expensive always the best. Comparing itemised quotes side by side reveals who's using quality materials and who's cutting costs on the subframe.
Best Time to Install Decking in Prague
The ideal window is April to October, with spring (April–June) being the sweet spot. Here's why:
- Ground conditions: Frozen or waterlogged ground in winter makes groundwork difficult and more expensive.
- Wood behaviour: Timber installed in moderate temperatures acclimatises better and is less prone to warping.
- Installer availability: Deck builders in Prague are busiest from June to August. Book in spring and you'll have more choice and potentially better prices.
- Enjoyment: A deck finished in May gives you the entire summer to use it.
If you're planning a deck for summer 2026, start getting quotes in February or March. Good installers in Prague book up quickly once the weather turns.
Maintenance: What to Expect After Installation
Your ongoing costs and effort depend entirely on your material choice:
- Softwood: Annual cleaning plus re-oiling or staining every 1–2 years. Budget around 200–400 Kč/m² per treatment if you hire someone, or buy oil for roughly 150–250 Kč per litre and do it yourself.
- Thermowood: Annual cleaning and oiling every 1–2 years. Slightly less demanding than softwood.
- Hardwood: Annual cleaning. Oiling is optional — hardwood weathers to a silver-grey naturally. Oil only if you want to maintain the original colour.
- Composite: Annual cleaning with soapy water. No oiling, staining, or sanding needed. This is the main selling point.
Regardless of material, keep leaves and debris off the deck in autumn and ensure drainage channels stay clear. Standing water is the enemy of all decking.
