What affects the price
- complexity of the roof structure
- region / voivodeship (province) (differences in installation prices between companies)
- whether the installation requires a sealing collar and additional accessories
- window make and model (Velux, Fakro, Roto have similar installation rates)
- additional work: moving rafters, plaster finishing, disposal of the old window
Usually included in the price
- installation of a new window in an existing roof opening
- basic sealing collar (in some offers)
Usually charged separately
- the price of the window alone
- blackout or thermal-insulating blinds
- strengthening or repositioning the roof structure for a non-standard installation
- plaster finishing around the window
Labour prices vary significantly between regions and companies (from about PLN 250 to over PLN 1500 per unit); offers combining the price of the window with installation and the price from renova24.pl (a 2024 article) were excluded.
Prices from customers and companies
Two types of entries: customers state how much they paid for the entire job and rate the contractor; service providers enter their price lists. Customer entries have three reliability levels: ✓ verified: invoice or receipt (the editorial team has seen a document matching the entry), ✓ verified: declaration (the author confirmed the entry using a link sent by e-mail) and unverified (how we verify entries); we do not verify company price lists. Price lists entered by companies are not included in the median at the top of the page; customer amounts are included only for services priced as a complete service.
