"Helemaal top. Mohamed heeft mijn vensterbank mooi opgehangen en ook nog een onverwachte complicatie met een verouderd stopcontact opgelost. "

"Roel heeft de vensterbanken netjes geplaatst. "

"Wij zijn ontzettend tevreden over het werk van InchoMar. Hij heeft onze vensterbanken vakkundig gemonteerd en alles tot in de puntjes afgewerkt. Wat wij vooral waarderen, is zijn perfectionisme: toen bleek dat wij zelf de verkeerde overzetprofielen hadden gekocht, kwam hij zonder problemen later terug om de juiste netjes te plaatsen. Dat laat zien dat hij niet alleen oog heeft voor kwaliteit, maar ook echt wil dat het eindresultaat perfect is. Een echte vakman die zijn afspraken nakomt en met wie het prettig samenwerken is. Zeker een aanrader!"

Frequently asked questions

Replacing an exterior window sill usually costs between €175 and €450, depending on the material, length, accessibility and condition of the base. A small window sill or sill brick is usually less expensive than a longer sill that also requires jointing, sealing or façade repair. Any material costs for sill bricks, natural stone, concrete, sealant, mortar or fixing materials may be added separately.

On average, replacing an exterior window sill takes about 3 to 6 hours. With an easily accessible location and a standard size, the professional can often finish more quickly. If old stones need to be removed, joints repaired or the base rebuilt, the job may take longer.

The professional first checks the existing sill, the connection to the window frame and the condition of the masonry or joints. The old sill is then carefully removed and the base is cleaned and prepared. After that, the professional installs the new exterior window sill, finishes the seams and joints neatly and checks whether rainwater drains away properly.

Zoofy works with experienced professionals who are reviewed by customers after the job. This means you get help from someone who regularly carries out façade, masonry and installation work and knows how to fit an exterior window sill securely and watertight. The reviews help you confidently let a professional into your home.

After the job, the professional remains legally responsible for the work carried out. If you have questions later about the installation or notice moisture, leakage or loose jointing, you can contact Zoofy. Zoofy also offers an optional paid warranty package for extra peace of mind.

Zoofy always tries to find a suitable professional to replace your exterior window sill. Availability depends on your location, when you need help and how accessible the window is. If someone cannot be found immediately, you will be informed.

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