Types of wall cracks to keep an eye on at home

Created: 13/03/2014

Your home is your palace, so it only makes sense that you would want to keep it in the best condition possible. If you aren’t very hands-on around the home, noticing a slight crack could be a cause for concern. However, instances of this happening usually turn out to be half as serious as you would think; here are some types of crack to look for to help you identify the cause before calling out a South London handyman.

The first are shrinking cracks; these are the narrow hairline fissures which are often seen around skirting boards and joins. Shrinkage cracks regularly occur in newly-built homes and are caused by the concrete as it cures – they can vary in size, depending on how it is mixed and poured. Fortunately, these have absolutely no structural impact whatsoever and are simple aesthetic issues which can be resolved quickly by applying some filler.

If the crack is noticeably larger than a fingernail, it’s definitely worth checking. The angle of the crack should be enough to tell you how much of a concern it could be; horizontal cracks in a concrete wall or stair-step cracks in a brick wall are a worry, and in these cases it is advisable to call in an expert as soon as possible. It’s also worth keeping an eye on the size of the split, with any gap wider than 3/16 inch (4.7 millimetres) a real cause for concern.

It might seem odd to check upstairs while identifying foundation damage, but there are some tell-tale signs that you can keep an eye out for by doing this. One of these is a binding door or window, suggesting that the openings of either have been skewed out of position because of structural damage. Another sign of foundation damage is cracks on the wallboard, particularly at the top and corners of door and window openings.

Should you have a long list of structural worries around the home, such as electrical, plumbing or decorating dilemmas, calling one of the Bromley electrical specialists or handymen could help to resolve all of these issues.
