Damp Walls

Damp Walls In Your Home

gutters

I posted on my blog, in November last year, about damp walls that arise as a result not having gutters on your home to control the flow of rainwater off your roof.

On Saturday I inspected a four-year-old property that had a one tile overhang on the roof, no gutters but had paving surrounding the house.

However, the external walls of the house were in a desperate state because of the three most destructive mistakes architects, developers, builders and homeowners make!

As a result, I’m going to repeat part of the issues mentioned in my blog again!

Damp walls caused by no gutters

Gutters collect the rainwater runoff from the roof, discharging it into downpipes which conveys the rainwater away from the house in a controlled manner. In addition, they also protect the timber roof structure at the eaves of the house. Furthermore, gutters protect the exterior walls, windows and doors of the house and its foundation from damp and potential damage.

The splashing up against the walls was the most serious cause of the penetrating damp on the walls of the house. Moreover, the crazing cracking (spiderweb-like fine cracking) in the plasterwork was the main indicator of the penetrating damp caused splashing up of rainwater. No cracking was observed higher up on the walls.

Even if your house has a reduced overhang at the eaves, gutters will still provide the required protection against heavy rain and wind storms your house may be subjected to.

Insufficient roof overhang at the eaves

Roofs with no gutters which have a two-tile overhang (600mm in the case of a metal roof) or less will allow water to pour from the roof close to the walls, windows and doors and the foundation.

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.

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.

High Water Bills

MY WATER BILL WENT WAY UP! HOW DO I FIND A LEAK?

leak

Your high water bill could be due to either a temporary increase in water usage or a leak. To find out if it’s a leak, first shut off all your water-using fixtures in the house.

Take the cover off your water meter box and flip open the protective cover plate on the meter dial. Normally, your metre box will be somewhere along the front property line, often near a corner. You may have to dig down a little in the dirt to find it.

The meter may be a newer one that has a small round or diamond-shaped low-flow indicator near the centre. The low flow indicator may be red or black like in the photo above. It should not be turning. But if it is, there’s a leak somewhere in your plumbing system. At a meter without a low-flow indicator, note the meter reading or take a picture with your cellphone. Check back in an hour or so and see if it has changed.

There are a number of places to check if the meter says you have water flow indicating a leak:

  • Leaking Taps

Not just the at the sinks. Also check the taps at the washing machine hookup, water heater, tub/shower, and the outside hose taps.

  • Leaking Toilet Cisterns (tanks)

A flapper valve that doesn’t seat properly at the bottom of the cistern will cause a leak. Check the ballcock arm and overflow tube as well, it may also be defective. Drop a dye tablet (available in most hardware stores specifically for toilet testing) in the tank. Do not flush, and wait for 15-minutes. If the colour shows up in the bowl, the toilet needs repair.

  • TPR Valve at the Geyser

The small valve with a flip-up handle at the top or side of the geyser called a Temperature and Pressure Release valve. This important valve is designed to open if the water gets too hot, to keep the tank from exploding. These valves sometimes fail by opening slightly and letting loose a slow trickle of hot water. The water normally runs in a steel or copper pipe to a location at the exterior wall. Find the termination of the TPR valve and check for a drip. NEVER work on these valves yourself! Only a suitably trained and experienced plumber should! Continue reading “High Water Bills”

Efflorescence

WHAT ARE THOSE POWDERY WHITE AREAS ON MY BRICK WALLS?

 

efflorescence

Efflorescence is one sign that is often dismissed as just being an eyesore and is given surface treatment only.  This is the presence of the white powder that forms on the face or surface of concrete, plasterwork and brickwork.

It is a cause for concern!

 

Efflorescence is a build-up of minerals and salts on the surface of the concrete, brick and plasterwork due to repeated bouts of excess water in the material. The minerals and salts that naturally occur in the material are dissolved when the brickwork, plasterwork or concrete is waterlogged with water.

Concrete, pavers, brickwork and plasterwork are porous and can absorb or wick water and draw salts to it like a tree transports water from its roots to its leaves. This is capillary action. When efflorescence happens, it can indicate a moisture issue that could potentially damage the structure.

When water reaches a building material’s surface, evaporation will occur. Water absorption and wicking will continue after the water evaporates and the salt is left behind. This eventually creates a high salt concentration, leading to osmosis.

What is Osmosis

 

Simply put, osmosis in building materials is the movement of water from a region of low salt concentration to a region of high salt concentration in the material.

During osmosis, when water moves toward salts and minerals to reduce its concentration, it can cause large hydrostatic pressures within the porous building material. As a result, these pressures can damage or destroy the material.

Osmosis can cause pressure that ranges up to 200 bar, exceeding the structural strength of concrete. Therefore, osmosis may result in porous building material cracking, flaking or falling apart. Continue reading “Efflorescence”
