Plastic skylight installation
The specialist installs your plastic skylight in a number of steps. In the step-by-step plan below you can read how the specialist works to install a roof window in your home.
Step 1: Determine the position of the roof window
First, the specialist examines the roof. He will check whether the roof structure is solid enough for the plastic roof window. If it is not, the specialist reinforces the roof with additional beams. He also determines the exact position so that the roof will be in the right place.
Stage 2: Preparing for installation
In preparation for installation, the specialist opens the roof. He removes the wooden structure and insulation, then lastly he removes the roof tiles. The specialist removes an extra layer of tiles around the skylight, so that he can properly damp-proof the roof at a later date.
Stage 3: Installation of the skylight
The installation of the plastic skylight involves a number of steps. First, the specialist installs the plastic window frames. Then he finishes the roof on the outside and puts back the roof tiles. Finally, he installs the glass. Then he checks whether the skylight is firmly fixed.
Stage 4: Finishing the roof
To finish the skylight completely, the specialist uses sealant and putty or to remove the last irregularities. He also finishes the inside of the roof again, by replacing some plasterboard, for example. Then your skylight is completely finished and you will enjoy the final result.
Handy tips for plastic skylights
You have read a lot about a plastic skylight. Are you planning to buy a skylight? Then read these handy tips so that you can get even better value.
Choose a burglar-proof skylight
Although a skylight sits high above the ground, burglars always see an opportunity to get to it. By choosing the right roof window, you will make it much harder for burglars to enter your home. Skylights with the Politie Keurmerk Veilig Wonen and the SKG quality mark are much more difficult for burglars to open and therefore the best choice.
Compare several quotes
Always choose to compare several specialists. When you compare quotes from several roof window specialists side by side, you choose the best price as well as the best quality. By comparing several quotes, you can also immediately see the differences between all cost items, such as material and labour.
Get a volume discount
Are you planning to install several roof windows? Then have this done at the same time. The specialist will then charge less call-out charges and you also have the chance of a nice discount. Also ask your neighbours if they are interested in a roof window. The more skylights you have installed at the same time, the bigger the volume discount.
