Window and door replacement
Window and door replacement with SDS-INVEST
We plan removal and installation of windows and doors, including sealing and finishing openings. Replacement can be coordinated with facade or interior renovation work.
Measurements and preparation
Before ordering, we check opening dimensions, reveal condition and installation conditions. We agree opening directions, floor levels and connections to the building insulation.
Installation and sealing
Fixings and sealing suit the wall structure and joinery manufacturer’s recommendations. We discuss layered installation, thresholds and sill connections.
Associated work
The scope may include removal, disposal of old windows or doors, sills and reveal finishing — each item is confirmed in the quote. Send quantities, dimensions and photos.
Poradniki: Window and door replacement
How should a flat be prepared for window replacement?
Provide clear access to windows and a route for carrying frames. Remove curtains, blinds and items from sills. Agree floor and furniture protection and temporary storage with the team.
Before installation day, confirm quantities, opening directions, colours and fittings. Order dimensions should be confirmed by the person responsible for measuring.
What should the installation scope include?
Compare quotations with the same scope: removal, opening preparation, installation, sealing, sills and reveal finishing. Disposal of old windows and doors should also be specified.
For doors, agree the finished floor and threshold levels. At handover, check leaves, handles and locks, and discuss adjustment and care.

FAQ — frequently asked questions
Is foam alone sufficient for installation?
Fixing and sealing methods must suit the windows or doors, wall and manufacturer's instructions. The offer should describe the complete joint solution, not just the gap-filling material.
When should windows be replaced during house insulation?
Agree the sequence before facade work starts. This allows planning of reveals, sills and the junction between insulation and frames.
Does the quotation include repairs around windows?
Reveal finishing is agreed separately. Specify whether you need only substrate repairs or also skim coating and painting.
Can I stay at home during replacement work?
Work can often be phased, but arrangements depend on the number of windows, access and scope. Agree with the team which rooms will remain available.
What is included in the price?
Installing new windows and doors and a full replacement including removal are different scopes. The quotation specifies dimensions, quantities, sealing and opening finishes.
