Why Is Window Installation Sometimes Expensive?

How to Know If a Window Company Is Trustworthy?
Look for:
- A valid Business Registration and relevant trade licenses

Why Hire a Professional Window Installation Specialist?
Poorly installed windows can cause leaks, drafts, and even structural issues. DIY or unqualified installs can lead to safety risks, especially in upper-level flats. Certified installers ensure proper alignment, sealing, and long-term durability.
Types of Window Installation — What Are the Differences?
- Aluminium Windows: Lightweight, rust-resistant, common in high-rise buildings.
- Sliding Windows: Space-saving and easy to clean — perfect for kitchens and balconies.
- Casement Windows: Opens wide for airflow; ideal for bedrooms.
- Fixed Windows: For lighting or decorative purposes with no opening function.
- Custom Windows: Tailored to unique shapes, sizes, or soundproofing needs.

Can I install soundproof or double-glazed windows?
Yes! Many Toby pros offer energy-efficient and soundproofing window options. Double-glazed windows offer enhanced energy efficiency and reduced heating bills with two glass panes and a spacer bar installed in between. The two panes are sealed together with air and insulating gas trapped in the gap between two panes. Double-glazed windows also offer noise insulation as sound vibrations are absorbed between the panes of glass.
Can you install new windows without removing the old frame?
In some cases, yes — known as retrofit installation. It depends on frame condition. By changing just the window and not the frame, this maintains the home’s original aesthetics so there is not much change. Retrofit installation, or “in-pocket window installation” is less expensive and less time-consuming as well since the existing frame remains in place.
