Section Title Schemes

Responsibilities of Owners and Body Corporates

Body corporates

I do a fair amount of inspections in sectional title schemes. Often, owners ask me if body corporates will pay for repairs inside their units. Obviously, their concern is about damage caused by external factors such as rainstorms, burst geysers and so on.

Each case is usually based on its merits. Usually, the body corporate’s trustees use their discretion when deciding to whom they allocate the cost of repairs and replacement. However, there are many grey areas and the differences between the owner’s and body corporate’s liability and responsibility.

The Body Corporate’s obligations

Body corporates are responsible for the repairs and maintenance and upkeep of the common properties.

Furthermore, the body corporate maintains all pipes, ducts, wiring etc. for the common property and services to more than one unit.

Your obligations as an owner of a section

You must maintain and keep in good state your section. Moreover, you must also keep any part of the common property to which you have the right neat and tidy. These are exclusive use areas such as gardens, patios, balconies, parking areas, garages etc.

Boundary Walls

Preventing and Repairing Cracks in Boundary Walls

Damaged boundary walls around your property can spoil the whole look and feel of your property. Furthermore, cracked and leaning walls can also pose a danger to passers-by should the wall fall over.

boundary wall
This was a wall that was butt jointed against the neighbour’s wall. The danger here is that when the wall falls over portions of the wall will be spread over the pavement and possibly into the road. If a pedestrian is close by serious injury could result!

This article explains the correct way to repair boundary walls and install expansion joints!

Firstly, if your walls have ugly cracks and broken plasterwork and brickwork at the expansion joints do not plaster them up as shown in the photos below!

This expansion joint was chopped open and plastered up. The joint will crack at the joint again. This is a waste of time and money and will cause more problems than before!

Furthermore, the work done on these boundary walls will result in more cracking in the walls!

Many boundary walls and retaining walls may fail prematurely due to the lack of provision for movement. However, this is usually not a fault in the materials used, but usually a lack of proper design. Even when the design is correct, the construction of the boundary wall and expansion joints are often faulty.

What is an expansion joint?

It is a separation between two portions of the same structure. A butt joint in a boundary wall is not an expansion joint!

Expansion joints in boundary walls

When building a boundary wall, an expansion joint is a separation designed to relieve stress on building materials caused by movement induced by thermal expansion and contraction. They are therefore specifically provided in boundary walls to avoid cracks occurring in the wall.

Temperature changes and seasonal changes mostly cause the movement in the boundary walls. However, expansion joints also permit movement due to ground settlement, seismic events and expansive soils.

Weekend Projects

Weekend Projects to Increase Resale Value

by Kay Pascale

resale-value

If you’re trying to increase the resale value of your home, there are probably more than a few side projects you want to finish before putting the house on the market for all to see. While some of these, like any kind of roof maintenance, are true renovations that likely require the help and vision of an expert, there remain some weekend projects that you can complete in a single weekend. Here are a few tips to help increase the resale value of your house.

Fix Outdoor Landscaping to Improve Curb Appeal

The first thing potential buyers will see when they walk up to your home is the landscaping. Do trees and bushes look overgrown? Is the lawn too long, or are there unsightly stumps and plants littering the yard? A little prevention in the form of weeding, gardening, watering, and trimming will have the front of your house looking immaculate and inviting to potential buyers. According to Home-Dzine, your lawn is probably one of the first things someone will notice about your house. Therefore, keep your grass trimmed, remove dead branches, and plant some flowers for a pop of colour.

Clean Your Gutters

Power washing the walls and the driveway is a great way to make your home look well cared for. This allows your house to stand out in a positive way from the rest of the houses on your street. Moreover, Gutters are often overlooked when cleaning up the outside of a home because you can’t see them from ground level. But rest assured it will make a big difference.

Make Any Necessary Repairs

Repairs can easily be completed in the span of a weekend. In addition, to ensure that there are no visible red flags, have a walkthrough or seller’s inspection. This will pinpoint any areas that need to be worked on prior to selling the home. Things that may be simply annoying to you might be deal-breakers for a buyer. In particular, leaky taps, mould damage, or a faulty light switch could be the difference between that SOLD sign and spending weeks or even months languishing on the market.

Plants Growing against Your House.

The Danger of Creeper Plants Growing Against Your House

Creeper Plants

A while back, I inspected a house in an older part of Johannesburg. From the road, the house was very pretty with an ivy creeper growing on the walls. However, having plants winding their way up your outside walls can cause actual damage to your house. Therefore, you should think twice before allowing creepers to grow on any wall in the first place.

In fact, the best advice is not to have any gardens within 1 metre of your home! Watering gardens against your home can cause uneven settlement of the foundation and cracks in your house.

The worst plants to plant against your house are destructive plants known as “self clingers”.

Self-clinging creepers

Self clinger creeper’s rootlets go into existing fine cracks and fissures, using them to enhance adhesion and occasionally penetrating the interiors of buildings through them. The mortar between bricks can be loosened through this activity and is often torn away from the wall when a creeper is removed. The same strong adhesion can result in chunks of plasterwork being pulled away, attached to the creeper vines.

In addition, on roof structures, creeper tendrils and rootlets can work their way under roof tiles and other roofing materials. Unless you remove the creeper maintenance, like painting and roof repairs, is impossible.

Moreover, any plants and shrubs with their foliage against your home may even dislodge gutters and roof tiles and can hold damaging moisture against wall surfaces causing moisture to penetrate into the wall and roof structure of your home.

Some articles and posts claim not all climbing plants bad for your house and some can provide “genuinely benefits”. However, the detrimental effect of having these climbers on your walls far outweigh any benefits they may have. Moreover, some climbing plants are very aggressive in the way they attach themselves to your walls and, if left unchecked, can cause serious structural problems.

Which creepers to avoid?

Ivy is a prime example. The sort of plants to avoid having grown up your wall are often the ones that have “suckers” or little mini branches like spikes, that burrow under the paint into the plastered walls and into the mortar joints of the face brick walls for a foothold.

Damp In Freestanding Walls

Do Your Boundary Walls Look Like This?

damp in boundary and garden walls

This photo I took during a client’s comprehensive buyers inspection had rising damp, falling damp and penetrating damp in the boundary and garden walls. In addition, the white marks on the wall were caused by efflorescence.

Often the maintenance of the walls that are attached to or which do not form part of our houses is neglected. These are our boundary, garden and courtyard walls.

These walls are very important in that they protect our privacy and security and are our first line of defence against intruders. Unfortunately, we sometimes do not make enough effort to protect them!

The greatest enemy of these walls is damp which penetrates into the wall from below, above and from the sides of the walls.

Rising Damp

Rising damp occurs as a result of capillary action at and below ground level into porous building materials. These materials are mainly concrete, bricks and mortar. The moisture rises up the wall in this way. It usually occurs where there is no damp proof course (DPC). Freestanding walls such as boundary and garden walls do not normally have DPC built into the walls because it would make the wall unstable. A layer of DPC would break the bond between the wall and its foundation.

The height to which the moisture will rise is determined by the evaporation rate and the nature of the wall. However, the normal limit for rising damp is generally about one metre above ground level.

Rising damp may show as a stain on the plastered and painted wall, the blistering of paint and loss of plaster. A damp area may be evident at the base of walls and in extreme situations, may cause the structure of the wall to wear away and crumble.

Falling Damp

Falling damp is caused by downward water penetration from the top of porous masonry walls. This is as a result of the top of a boundary wall not being adequately waterproofed, if at all.

Walls should be:

  • properly sealed at vertical expansion joints;
  • repaired at copings that have cracked or deteriorating mortar joints;
  • cleaned to prevent the build-up of dirt and moss on upper surfaces of stone or brickwork.
  • Leaves, bird manure, moss and dirt on top of the walls contain weak acids and salts which can promote decay of the masonry and paint if absorbed.

Penetrating Damp

Penetrating damp is a common form of damp. It occurs as a result of the horizontal ingress of water through gaps, cracks and joints in the wall’s structure. Penetrating or horizontal damp can be due to your or your neighbour’s irrigation system spraying against the boundary wall. Moreover, foliage growing against the wall (bushes and trees)can also be the cause. Other causes are deteriorating paint finishes and inadequately ruled joints which allows moisture intrusion into faced brick or stone walls.

Penetrating damp tends to produce localised patches of dampness and decay, whereas rising damp may affect the base of the wall.

Efflorescence

Efflorescence occurs where an appreciable quantity of soluble salts and moisture is present in the masonry. It routinely occurs in masonry construction, particularly in brick and concrete. It typically occurs during the initial curing of the cementitious product. Moisture carries these salts to the face of the masonry or concrete where the moisture evaporates.

As the water evaporates, it leaves the salts behind as a white fluffy deposit. Therefore, to remove it, brush the deposit off when the wall is dry. It usually disappears with time after rains or washing with water.

Efflorescence is generally an aesthetic concern and not a structural one. However, where there is excessive efflorescence, the crystallizing salts within the pores of the masonry can disrupt even the strongest material. As a result, this can lead to the breaking up and crumbling of the structure.

How to prevent damp damage in your freestanding walls

Rising Damp

Rising damp is not easy to resolve in any freestanding, boundary or garden walls because of the lack of DPC.  However, you can do the following:

  1. Make sure that there is no pooling of water against the wall. Good drainage away from the walls is essential. If you have a low point in your garden against your boundary walls you will need to create a hole in the wall at the lowest point for the stormwater to drain away. Your neighbours have to accept a certain amount of your stormwater by law.
  2. Try not to overwater your gardens against boundary and garden walls. overwatering will result in sodden earth around the walls and, as a result, rising damp in the wall.
  3. Keep leaves and other debris on the ground which may retain water away from the walls.

Falling Damp

  1. You should waterproof the tops of all freestanding walls with a layer of an acrylic waterproofing system or any other system to prevent moisture intrusion into the top of your boundary and yard walls.
  2. If there is a concrete or brick coping on top of the wall you must ensure that the joints form a water-resistant seal. You should seal all deteriorated joints or porous joints between the bricks and copings.
  3. Seal the top of expansion joints to prevent water from entering the joint with a silicone sealer.

Penetrating Damp

  1. If your freestanding walls are plastered, check the paint finish regularly. It may be time to repaint if the finish is chalky.
  2. If you have a sprinkler system make sure that you are not watering your boundary walls. Sprinklers heads are normally adjustable. If yours are not, change them.
  3. Trim bushes and shrubs so that there is a gap between the foliage, branches and the walls.
  4. If it appears that the moisture is from your neighbours’ sides, you will need to talk to them about the problem.
  5. Clean out and seal vertical expansion joints with a good silicone sealer. Any cracks should be sealed as well. Furthermore, if your plastered walls are covered in crazing cracking wash the wall down. Thereafter, when the wall is dry, seal the wall with a sealer and repaint the wall.

Efflorescence is a sign of damp

Efflorescence is caused by moisture absorbed in the wall evaporating and leaving behind salts as a white powder. Therefore, if you repair and maintain your walls as suggested above, very little efflorescence should appear on your walls.

I am not specifically promoting Prominent Paints as all the well-known paint manufacturers produce the same required paints and sealers. You can use most of them to repair and maintain your freestanding walls.

However, Prominent’s video provides very good advice on how to repair moisture damage to boundary and garden walls!
