What to consider when buying a dated property

Materials, tools and technology are continually innovating – and there’s no exception when it comes to the construction industry. Where some methods are still used today, others have evolved or been completely disregarded. But with some structures still standing on outdated building methods, what should you look out for before buying an older property? Let’s find out.

Damp

Although older buildings are inherently damper than modern structures, this is not necessarily a problem. Older buildings have mostly stood the test of time because they have been built using breathable, damp regulating materials such as lime-based mortars and moisture absorbent brick and stone.

In simple terms, moisture is absorbed and passes through external walls from outside to inside when external humidity is high – and vice versa when internal humidity is higher. With no damp course, it is also important external drainage minimises rising damp from stonework under the ground.

Mould

Persistent and excessive damp leads to mould which can pose a serious threat to your health. The remedy to remove mould will depend on the exact cause, which will typically stem from excessive moisture finding a way into your property but not a way out.

Unless there’s sufficient evaporation in an older property, moisture and condensation on internal walls and window frames will continue to form mould. If you need an expert opinion on the cause, feel free to get in touch.

Poor maintenance

Looking after older buildings calls for an understanding of the building materials used and how they perform. Applying methods used on modern housing can be totally counter-productive and exacerbate a problem rather than solve it.

For example, if an older building is repointed with normal cement rather than a lime-based mortar, damp inside the building will have lost its main escape route and the whole job will have to be re-done.

If you’re looking to buy an older property with recent work completed on its external walls, you should get an expert opinion as to the suitability of the materials used.

Energy inefficiency

Cavity walls not only keep the damp out, they also help insulate a building, particularly if the cavity is also filled with mineral wool insulation.

With its solid walls, an older house is inevitably more expensive to keep warm, even if it has been modernised with double glazed windows and copious amounts of loft insulation. It’s a potential expense to bear in mind should you consider to purchase an older property.

Structural Issues

In most cases, older properties do not have foundations as deep as newer alternatives, which can make them more susceptible to settling and subsidence issues.

You should also check the structural timbers in an older property as they could be more prone to decay from either insect damage or rot caused by long-term damp.

Some of the structural elements may be concealed or difficult to access during a viewing. In these instances, a building survey could save you a lot of trouble later down the line.

Outdated systems and toxic materials

Dated electrical wiring not only sets you back on more expense, but can also be a danger to your health. Old electrics run two big risks:

  1. They may not have the capacity to handle modern needs, leading to overloaded circuits and possible fire hazards.
  2. Cable insulation deteriorates over time and eventually could leak or short circuit, causing possible electrocution or fire.

You should also get a second opinion on dated plumbing systems, especially those made from concealed lead pipework which could present a risk to your long-term health.

Should you buy an older property?

Although older properties project a charm you might find lacking in newer alternatives, they can often come with an expensive list of repairs and adaptations.

As with any property purchase, new or old, be certain about what you’re buying by booking a building survey. Not only will it give you peace of mind, but it could save you a fortune in years to come. If you need further advice, feel free to call our team on 01273 031646.
