Skylights are not very expensive to purchase; the installation forms the bulk of the purchase. It may be recommended that a licensed contractor fit the skylight, though it can even be done yourself if you are good with your hands and have done such mechanical jobs before.
If you choose to get it done through a contractor, it's best to always research a few companies to find the best rates and service. Recommendations from friends are a smart way to make a decision. If you are looking for skylights contractors browse www.calidad.net.au.
Most installations involve just three easy steps. First, you need to determine the location and cut an opening into the roof and the ceiling. Then, the skylight unit has to be attached to the roof, making sure all joints are sealed. And lastly, the light shaft from the roof to the ceiling has to be made with drywall or paneling.
Complex skylight shafts, however, can take a lot of time to construct. Structural work may have to be done or roof-framing members may need to be altered to create the light tunnel. This cannot be attempted at home even if you consider yourself very skilled. It's best in such cases to get help from a professional installation agency. Most manufacturers offer installation service.
