"De klus is naar tevredenheid vandaag afgerond. De eerste factuur heb ik zojuist betaald. Zodra ik de aanvullende factuur voor het afwerken van de ramen ontvangen heb, zal ik deze voldoen. Harm is een vakkundige en harde werker. Bij deze klus had hij enige vertraging i.v.m. een te repareren bedrijfswagen. Als hij met mij hierover meer duidelijk had gecommuniceerd, had dit irritaties over het afronden van de klus kunnen voorkomen. "

Frequently asked questions

Replacing a Velux GGL 4 usually costs between โ‚ฌ450 and โ‚ฌ1,100, depending on the condition of the roof, accessibility and which new Velux roof window is installed as a replacement. A same-size replacement is often cheaper than a situation where roof tiles, flashing, insulation or interior finishing need adjustment. Material costs for the new roof window, flashing kit, insulation, sealant or finishing may be charged separately.

On average, replacing a Velux GGL 4 takes about 3 to 6 hours. If the new roof window fits well and the roof is in good condition, the job can often be completed within one day. Leakage, damaged roof tiles or extra interior finishing may take longer.

The professional first checks the existing Velux GGL 4 roof window, the roof surface, roof tiles and the connection around the window. The old roof window is then removed and a suitable new Velux roof window is installed with the correct flashing kit. Finally, the connection is finished watertight and the window is tested to make sure it opens, closes and ventilates properly.

Zoofy carefully selects professionals based on skill and reliability. You can view reviews from previous customers and see who will carry out the job. This helps you arrange a professional who suits the task and gives you confidence before the work starts.

After the job, the professional remains legally responsible for the work carried out. If you have chosen Zoofyโ€™s optional paid warranty package, this gives extra certainty on top of that legal responsibility. For questions about the roof window, finish or aftercare, you can contact Zoofy after the job.

Zoofy does its best to find a suitable professional to replace your Velux GGL 4. Availability depends on your location, timing and the condition of your roof and roof window. If no professional can be found, this will be clearly communicated to you.

You pay only through Zoofy and never directly to the professional in cash or by card. After the job is finished, you can pay easily using a QR code. Payment by email invoice is also possible.
