Our fitting service
In Belgium, it is our own employees who install the Tomsgates pet doors. In the Netherlands, Norway and Great Britain we organize the installation for you with our local partners. So we guarantee the service and quality.
We install our dog and cat doors in walls and doors. An installation in a door takes about 2 hours, an installation in a wall will take about 5 hours.
We are punctual, work with dust extraction, take the demolition waste materials with us and leave everything neat and tidy. The price is determined in advance, no settlement afterwards. If you have a VAT benefit (see below), we will refund the excess VAT paid within 14 days of installation.

Tips & Tricks

The installation template
Each pet door has an installation template made of sturdy cardboard with a protective border. Follow the dashed line for cutting out the hole in the door or making the opening in the wall. The extra cardboard protective border will help you to keep the door or wall free of machine scratches.
The exact position of the pet door
Once you have measured where you want to place the pet flap, first drill a hole through the door or wall. Then you can measure in detail whether the pet flap ends up exactly where you want on the inside as well as on the outside. Measure twice, then saw or cut.
Wind & Waterproof
If the pet door is installed, seal on the outside with silicone between the frame and the door or wall. You will see that the outside frame is already equipped with a swell band to ensure a good connection but that is the second protection. The first one is your kit joint. Then you can be sure that no wind or water can penetrate through the mounting opening. For wall pet doors, it is advisable to seal the edge of the inner wall with PU foam so that no wind can get in from the cavity.
Paint first, then install
If you have bought a natural finished pet door that you wish to paint, paint it in before installing it. After all, painting is easier at a worktable than on your knees in front of the door or wall.
