Terrace fence: the homeowner's complete build and buying guide

Every well-planned and properly built terrace is like a living-room extension in the fresh air. But however beautiful your decking may be, there is one element that ties the whole space together, providing both safety and visual appeal — it is the terrace fence.

Many homeowners leave fence planning to the last minute, which often leads to wobbly posts, unsuitable materials or a dull design. In reality, building a terrace fence is one of the most critical stages in creating an outdoor space. Whether you choose traditional wood, modern glass or a clever adjustable louvered system that acts as both a safety barrier and a windbreak and privacy screen?

Why is a terrace fence essential? (Safety and design)

A terrace fence serves two main functions: it saves lives (especially where small children and pets are concerned) and frames your garden aesthetically. Before you reach for the saw, you need to understand both the physical requirements and the design rules.

Safety requirements and building standards in Estonia

As a homeowner you should know that, from a certain height upwards, terrace fence is no longer a matter of taste but a safety element required by law. General building practice and standards in Estonia provide that, where the terrace surface is more than 50 cmabove ground level, a fence is mandatory.

• Handrail height: A safe terrace handrail should have a standard height, measured from the ground (or decking), of 90–100 cm. For balconies and very high terraces, this requirement is often 90–110 cm.
• Gaps in the fencing: If there are children in the household, you need to watch the spacing between vertical or horizontal battens. A safe gap is a maximum of 10 cm, to prevent a child's head from becoming stuck between the rails. You should also avoid the ladder effect (horizontal boards that a child can climb over the fence on) where high, dangerous falls are possible.

Visual boundary and the look of the home

In addition to safety, a fence defines the space. A terrace without a fence can feel bleak and unfinished, blending too much into the lawn. A well-chosen fence creates a clear "room outdoors" feel. If the aim is not only safety but also to create a wind shelter or screen yourself from neighbours' eyes, consider combining or replacing a low fence with a proper terrace wall.

Different materials: How to choose the best terrace fence?

Today's market offers homeowners an endless choice of materials. The right decision depends on the architecture of the house, the budget, and your willingness to maintain the fence.

Wooden terrace fences – Timeless classic

The most common and most affordable option is undoubtedly wooden terrace fences. They are easy to build, the material (impregnated pine or spruce, thermowood, Siberian larch) is readily available, and the design options are limitless (traditional cross-boarding, dense verticals or a stylish diagonal). Pros: Natural, warm, DIY-friendly, easy to repair and repaint. Cons: Wood needs maintenance every couple of years (washing, oiling or painting). If neglected, the fence rots or loses its visual appeal.

Glass railings – Openness and luxury

Glass railings for the terrace are a favourite in modern new-builds. They are used where you do not want to block a wonderful view of nature (for example toward the sea or the forest). Pros: Maximum transparency, protection from the wind, a very exclusive look. No oiling or painting required. Cons: A very expensive solution. Requires constant cleaning, because every fingerprint, raindrop and speck of dust is immediately visible. A closed glass enclosure may create an unpleasant greenhouse effect on the terrace in summer (air does not move).

Building a terrace fence yourself (DIY guide)

Ready to get hands-on? A terrace fence must be rock-solid. The most common mistake DIYers make is that the fence becomes "wobbly" over time.

Fixing the posts and building the frame

Golden rule: A terrace fence's strength does not come from the handrail or the boarding, but from how the vertical fence posts are fixed!

1. Fix to the frame, not to the board: Never screw a fence post (e.g. a 90×90 mm timber) simply onto a floor board. The post must extend through the floor and be fixed with strong through-bolts (not ordinary screws) to the terrace's load-bearing frame (the joists).
2. Support brackets: Bolt the post to the frame at at least two points. Where possible, use internal metal angle brackets to prevent the post from "rocking" sideways.
3. Spacing: Leave a maximum of 1.2 to 1.5 metres between posts, especially if you are installing heavy glass or louvered-screen brackets.

Fence maintenance and longevity

To make sure your terrace fence is not rotten or faded in 5 years, you need to invest in it after the build is finished, too.

Spring maintenance and oiling of wood

If you built wooden terrace fences, spring maintenance is unavoidable.

1. Wash the fence with a special wood-wash brush and a terrace-cleaning product. Do not use a pressure washer that is too strong, which would damage the structure of the wood.
2. Let the wood dry completely for a couple of days.
3. Apply wood oil or stain with UV protection (pigmented). Pay special attention to the top and bottom ends of the vertical boards, where moisture seeps into the wood most easily!

Maintenance-free solutions: Wash and forget!

If you chose the innovative solution and used as slat profiles for example aluminium, or covered the terrace with glass, your life is significantly easier. Glass railings need only ordinary window cleaner. For adjustable slats (and their plastic brackets) an autumn and spring clean with water is enough. To keep the moving parts smooth, apply a little silicone oil between the brackets once a year.

Quick summaries

• Safety first: If the terrace is more than 50 cm above ground level, a 90–100 cm high terrace fence is mandatory.
• Strength starts from the bottom: Fence posts must always be bolted to the terrace's load-bearing frame (the joists), not to loose floor boards.
• A wider handrail is functional: A wide "drink rail"-style terrace handrail binds the posts rigidly together and provides a comfortable resting surface for drink glasses.
• Dynamic design: A movable Louvered screen offers a huge advantage over glass and rigid wood, giving flexible control over both wind and privacy.
• Prefer a maintenance-free option: If you use adjustable systems, invest in aluminium slat profiles, which do not swell with moisture and never need oiling.
