Smoke detectors are very crucial pieces of safety equipment in your home and it is now also mandatory in NSW that residential properties have at least one smoke alarm on every storey. Not many people are aware of this, but a large percentage of fires in homes cause massive destruction because the smoke detectors didn’t function the way they should have.

The unfortunate fact is that we almost always take these fixtures for granted; we get them installed and rarely even notice they are there on the ceiling until they get set off accidently or when their batteries go dead. Improperly installed smoke detectors or even poorly-maintained ones will only end up letting you down exactly when you need them.

It’s important that you make smoke detector maintenance a part and parcel of your regular home maintenance routine. There two main types of smoke alarms used on residential properties:

These have minuscule quantities of radioactive material that reacts to the particles that are emitted when a fire breaks out, and that sets-off the alarm. These alarms are extremely effective in the detection of fast-flaming fires in which there isn’t too much of visible smoke.

These have photocells with a light beam that shines away from the cell. If smoke enters its test chamber, the smoke particles scatter some of the light; this hits the cell and triggers the alarm. These types of smoke detectors are ideal for detecting smouldering/smoky fires, which is how residential fires typically are.

Regardless of the types of alarms installed on your property, it doesn’t take more than a few minutes annually to ensure that these devices are in a working order at all times. The few steps you should take are:

Aside from the regular maintenance, it’s also very important that you consider how many smoke detectors you have and how they are powered. The best way to increase the effectiveness and safety of these devices is to upgrade your home’s smoke detection setup. The things to focus on are:

For large projects, a simple notepad and pen are not sufficient to provide accurate and timely cost estimates to clients. The good news is that there are some pretty good estimating software programs now available that do the job. Both residential and commercial contractors can save time, money, and win more bids by providing professional job estimates. These programs also offer the ability to manage projects, bill clients, and keep track of change orders. They feature a wide range of options for any size of contractor.

TurboBid is one of the most well received and fully featured estimating programs on the market. It contains a user-friendly graphical interface and offers training courses through their website. The software can connect to national and local material supplier databases to keep pricing updated throughout the bidding process.

Change orders and revisions are simple. The software will generate automatic reports and professional presentations for clients. It also allows fine adjustment of man-hour estimations in different locations of the building. This includes ceilings. The program can account for different worker skill levels and upcoming wage increases for longer projects.

The built-in database includes tens of thousands of parts and full assemblies to allow for quick and easy estimation. The program incorporates national and local electrical code requirements to ensure bids are code compliant. In addition, it has a value engineering feature that suggests code-compliant changes to the customer’s blueprints. This can ultimately save money by adding, removing, or relocating devices.
