Residential security doors
An increasing number of homeowners are recognising the invaluable benefit of securing their living spaces. Our residential security doors, like their commercial counterparts, are exceptionally strong and reliable, built with various combinations of reinforced steel and timber, optional multi-lock systems and officially accredited fire sealing properties.
At Costello Security Installers we are aware that the appearance of your home, garage or out-house is also an important consideration. We offer a considerable range of styles, designs and colour finishes, including varnished wood finishes, a large number of window panel positioning combinations and many more features.
Important considerations when choosing security doors and steel security doors
When you are considering purchasing steel or reinforced timber security doors, it is extremely helpful to obtain the advice and expertise of time-served professionals.
In order to match any business image you may be wishing to emphasize, our security doors come in a range of styles, designs and colours. In terms of practical security protection, our friendly team will be more than happy to advise you of the best specifications for your working environment. Many residential and commercial security doors are fitted with tempered, break-proof glass, which is extremely effective at keeping out both the elements and unwanted intruders.
All of our residential security doors come with a CE certificate of conformity for burglary prevention, insulation and rigidity.
