Reviews

I am writing this review for Jim as a tribute to his excellent work he has done to our house. He came to do our front fence only but ended up doing my full house. His work ethics, conduct by him and his assitant Ritso were exemplary. Honestly I am writing that I am missing them in the morning as they come and don't waste time with their work. Very cheerful and welcoming person. He is very accommodative our request and worked with us to fulfil our requirements. Arull and I have a pleasure of recommending Jim for any rendering work for any one looking for a professional high quality work. This is evident from the compliments I am getting from people who passes our house and stop and talk to me. My house status has now become normal house to a best house in the street which competes with all new houses built in my street recently.Again thank you Jim for your excellent work and your caring nature. Before and after photos shows his excellent work
Very Honest and efficient company to deal with. Highly recommend.
Everything you could ask for in a job. Reliable and friendly tradesmen, quality materials and workmanship, and all at a fair price. Couldn't recommend Jims Rendering Sydney enough.
BRILLIANT WORK - Jim and his guys did a marvellous job on my 5 bedroom house in St Ives. Quality, honesty and a great finish to what was a tired old red brick house. Can’t thank you enough Jim. Great work.....
Jim rendered an internal wall we had repaired after a large crack appeared and plaster started falling off the wall. Jim provided us with a very reasonable quote, was punctual in starting the job, kept us informed during the work, and cleaned up afterwards. We are very happy with the work carried out and recommend using Jim's business to anyone needing similar work done to their home.
We would like to say a great big thank you to the Jim and his team, they turned our house into our dream home!

What Causes a Wall Crack?

Broken brick walls and cracked brick walls can indicate many different problems, from simple cosmetic issues to more serious issues that may indicate problems with your home’s foundation. Cracks in walls may occur in any building, whether new or old (you can read here if hairline cracks in a new wall are normal). Some cracks may not cause any problems, while others could lead to a hazardous situation. If you do not address problem cracks in walls, the deterioration of the foundation can rapidly devalue the property. Cracked wall in an arch, wall cracks in an arch after resin injection into the foundation ground.

Can a blue board be used as an external wall material? Why do some builders use blue board/concrete sheets as external walls now – isn’t that supposed to be used as internal material? Is it safe to use the blue board/concrete sheet as the external wall? The blue board from James Hardie is called HardieTex –it’s an exterior wall system made of concrete, painted with a blue primer coat, and specifically designed to be used outside as an exterior wall surface, coated with an acrylic rendering. The cement sheeting product they recommend for use indoors (i.e. in wet areas like bathrooms and laundries) is called Villaboard … and it’s not blue. The CSR version of the blue board is the Cemintel Texture Base Sheet, and it’s pretty similar to the Hardie product – an external wall cladding system that’s designed to be finished with an acrylic render. The cement sheet system they produce which is designed for indoor applications is called CeminSeal Wallboard.

Blue Board Most common as an exterior wall cladding, Blueboard is a solid-based 7mm sheet, which is designed for acrylic rendering, providing a beautifully rendered finish, without the masonry appearance. Available in a range of different sizes, blue board has now become a very popular fencing material and is used frequently in courtyard surroundings.

When do wall cracks indicate structural damage?

Larger cracks that exhibit these characteristics may indicate weaknesses within the structure’s foundation: On one side of the wall is higher than the other Cracks are wide than about 5 mm (or half a centimetre). A problematic wall crack will typically begin at windows, doorways or corners of buildings. Generally, smaller hairline cracks are not caused for concern. These are generally the result of seasonal expansion & contraction of soil beneath the building over time & can be easily patched and repainted. There are different types of cracks it can be, Horizontal cracks, Diagonal cracks, Vertical cracks, and Minor cracks.

What causes large cracks in walls?

Large cracks may appear due to the weakening of the structure caused by water seepage into the soil beneath the foundations. These types of cracks can occur anyplace in the walls. This generally occurs because the water damage in the soil beneath the set portion of the building is either extremely moist or exceptionally dry.

How do fix large cracks in walls?

The best long-term solution for fixing large cracks in foundations is to remove and replace them. This process is called underpinning (also known as trenching). As the building is levelled, the cracks in the walls may start to close or get smaller (preparing plaster or rendering walls for painting). Windows and doors will probably also start to function correctly again. Traditional underpinning or levelling techniques involve digging up parts of the foundations, pouring in cement, waiting for it to dry (which can take days), and then lifting the normal house up onto new supports.

At Jims Rendering, we use different techniques to fill the crack on your property. We can plaster a crack resulting from improper priming and painting. We use a unique plaster compound, a drywall joint compound for crack stitching when we repair older homes.

What is drummy render and how does it occur?

When the cement or plaster pulls away from the concrete wall, leaving a gap behind it. Drummy render occurs when the cement or plaster render coating becomes loose. It produces a weak, hollow sound when tapped with a bar (sounds like a drum, or “drummy”). Many different causes of drummy render have been discussed by many plasterers. Heavy vibrations, water ingress (see below), insufficient cement in the mix, render applied too thickly, or it could be that when the plumbers and electricians chased up the walls, the dust left behind formed a membrane separating the render from the substrate. It could be any, all, or none of these factors, but these are the most frequently mentioned possibilities. It may be some or all or none of these factors, but these are the most commonly quoted possibilities. What is concrete spalling? The majority of slab edges become wet due to rain, garden watering, or contact with the ground. Dampness can permeate from the outside to the inside of a building in some cases (moisture ingress), affecting internal walls and/or finishes. Consistent dampness of the exposed face of the concrete slab, efflorescence, drummy render (as mentioned above), pungent odours in floor coverings, mould growth, watermarks, rusting, and external wall paint peeling/bubbling/blistering are all symptoms of slab edge dampness.
