Who is window installation for?
Window installation and replacement is right for you when you want to improve your home's energy efficiency, living comfort, and appearance — while ensuring that the structures and sealing will last well into the future. We install and replace windows in blocks of flats, terraced houses, and detached homes, from individual windows to full-facade window projects.
Old windows past their service life
Your windows date back decades, the seals are leaking, the frames are warped, or the paint is flaking. You want new, airtight, and low-maintenance windows that can withstand Finnish weather conditions.
Draughts and heat loss
You feel draughts indoors, and floors and surfaces near windows are noticeably colder in winter. Heating costs are rising and you want to improve your home's energy efficiency with new, better-insulating windows.
Improving your home's appearance and natural light
You want more natural light or a cleaner, more modern look for the facade and interiors. New windows update the frames and glazing bars to a contemporary style.
Sound insulation and peaceful living
You live near a busy road, railway, or other noise source. You want to improve sound insulation so that the indoor environment is calmer and more pleasant.
Renovation or facade upgrade
You are carrying out a larger renovation or the housing company is updating the facade. It often makes most sense to replace windows at the same time, so the work is coordinated as a single project and structures don't need to be opened up multiple times.
Property value and sale
You are preparing to sell your property and know that new or well-maintained windows are a major selling point for buyers. Upgrading windows reduces the need for future renovations and makes the property more attractive.

Factors affecting the price
- Number and size of windows: The number and size of windows significantly affect the total price. Custom-sized or bespoke windows are more expensive than standard sizes.
- Glazing type and energy efficiency: Triple glazing is more expensive than double glazing but saves on energy costs. Specialist glass such as acoustic or solar control glazing increases the price.
- Age and condition of the building: Older buildings may require additional repairs around the frames. The need for structural modifications or insulation work affects the price.
- Complexity and schedule: High-level windows, difficult installation locations, and tight schedules can increase the labour cost. Interior and exterior finishing adds to the overall expense.
