Common Pitfalls

Some common mistakes to be wary of:

Quality of the types of materials used

For instance, if you are building an unplastered wall, bricks need to be of higher quality seeing that they are exposed to the elements. Should you opt for a steel palisade or any other metal type fence, it is good practice to have it galvanized, especially if you live close to the seaside. Timber fences should preferably be a harder wood. This list can be never ending, bottom line is; Don’t skimp on materials and spend a little extra to ensure your wall or fence is a longer lasting construction.

Builder to be employed to construct the wall

Make sure they know what they are doing. Get references from previous clients and ask your friends to refer brick layers or contractors they have used. Keep an eye on how often the owner or foreman is on site and, if need be, address any issues before payment date. Some builders will require up front payments. Make sure you do not overpay them and never pay the full contract amount before all construction and finishing is completed.

Local municipal regulations

As mentioned under the first heading of this article, different Municipalities have different policies. Get your plans approved before you construct your boundary wall to prevent penalties and extra costs.

Heritage sites

There are particular regulations for any site with heritage or ecological value. Ensure you are in keeping with these.

Added features

The need for security and privacy has led to higher boundary walls. Just keep in mind, high solid wall surfaces may result in a mundane and hostile street view and may also conceal criminals from the public’s view. Wall lights and any other decorative work must firstly be of exterior quality and secondly should not be overly expensive and be positioned so it does not entice vandalism or theft.

These are a few examples as this list can become inexhaustible.
