Quick estimate
The estimate multiplies the rates on this page by the quantity entered. It does not include minimum order charges, travel or materials unless they are included in the price.
What affects the price
- windowsill material: PVC is the cheapest to install, while stone (granite, marble, composite) is more expensive
- removal of the old window sill: installation with removal costs more than installation alone
- type of installation: so-called warm installation incurs higher costs
- city: rates can be higher in large cities (e.g. up to PLN 160/linear metre for engineered stone)
Usually included in the price
- labour only for installing the window sill in a prepared opening
Usually charged separately
- material (the window sill itself), charged separately
- removal of the old window sill, unless ordered together with installation
- edge polishing or bevelling (additional PLN 20-40 per linear metre)
- levelling the substrate with mortar if required by the recess (additional labour PLN 40-50 per linear metre)
Prices cover the installation of an internal window sill; external window sills are priced separately.
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.
