FAQ

Wat kosten nieuwe ramen en deuren?

De prijs hangt af van materiaal, afmetingen en plaatsing. PVC is meestal het goedkoopst, aluminium zit in het middensegment en hout is vaak duurder. Voor een exacte prijs is een offerte nodig.

Wat is het verschil tussen PVC, aluminium en hout?

PVC is het best isolerend en budgetvriendelijk. Aluminium is sterk en geschikt voor grote glaspartijen. Hout heeft een warme uitstraling maar vraagt meer onderhoud.

Bespaar ik energie met nieuwe ramen en deuren?

Nieuwe ramen en deuren beperken warmteverlies. Je verbruikt minder energie en je EPC verbetert. De exacte besparing hangt af van je huidige schrijnwerk en de nieuwe profielen.

Kom ik in aanmerking voor een premie?

Ja, als je ramen en deuren voldoen aan de U-waarden. Voor ramen is dat maximaal 1,0 en voor deuren 2,0. De premie hangt ook af van je situatie en inkomen.

Hoe lang duurt de plaatsing van ramen en/of deur(en)

Meestal enkele dagen. Dat hangt af van het aantal ramen en/of deuren, en de grootte van het project. Grotere projecten duren iets langer.

Moet mijn gevel aangepast worden?

Niet altijd. Maar een correcte aansluiting is belangrijk. Zo vermijd je koudebruggen en verlies je geen isolatie.

Wanneer moet ik mijn ramen en deuren vervangen?

Bij tocht, condens, slechte isolatie of verouderde profielen. Ook bij een renovatie van je woning is het vaak het juiste moment.

Very satisfied with this ‘young’ company. After visiting the site, we received a very clear and accurate quote. Excellent value for money. They respond very quickly to emails. The work was carried out very smoothly. Hats off to the team that came to work for us. The site was also left very tidy afterwards. We definitely recommend Cleys!
Very satisfied with this company, very quick, friendly, and personal contact, our side wall was sprayed with cork in record time.
Cleys exceeded all expectations with the renovation of our terraced house's facade! We appreciated the smooth communication with everyone involved, the manager, site supervisor, and craftsmen, as well as the accurate planning. Diego, our site supervisor, doesn't sell empty promises, but sound advice based on practical experience.
We had our facade insulated and covered with crepi. We are very satisfied with our collaboration with Cleys. A professional team from quotation to delivery. Everything was cleaned up nicely at the end of the work. Good guidance from site manager Diego. And a fantastic end result. Thank you, everyone.
