When choosing a window company, many homeowners focus on the product itself. While high-quality windows are essential, the way they are installed is just as important. Even the best windows will underperform if they are poorly fitted.
At Isis Windows, we have taken a different approach since 1997. All of our installations across Oxford and Oxfordshire are carried out by our own experienced in-house fitters, not subcontractors. This commitment plays a major role in the quality, consistency and reliability of our work.
What does “in-house fitters” actually mean?
In-house fitters are directly employed by the company you choose, rather than being hired on a job-by-job basis. At Isis Windows, our fitters are part of our team and work exclusively on our installations.
This means:
- They are trained to our standards
- They are familiar with our products and processes
- They represent our company on every job
For homeowners, this provides reassurance and accountability from start to finish.
Consistent workmanship on every installation
One of the biggest risks of using subcontracted installers is inconsistency. Different teams may work to different standards, leading to varying results.
With in-house fitters:
- Installation quality is consistent across all projects
- Workmanship reflects our long-standing reputation
- Attention to detail remains high on every job
This consistency is especially important in Oxfordshire, where properties vary widely in age and construction.
Greater accountability and responsibility
When fitters are directly employed, responsibility for the installation stays with one company.
At Isis Windows:
- We take full responsibility for the installation process
- Any issues are handled directly, without passing blame
- Communication is clearer and more efficient
Homeowners know exactly who to contact and can trust that concerns will be addressed promptly.
Better knowledge of products and materials
Our in-house fitters work with Isis Windows products every day. This familiarity ensures windows are installed correctly and perform as intended.
Product knowledge leads to:
- Correct fitting of modern glazing systems
- Proper sealing and insulation
- Accurate alignment for smooth operation
This level of expertise helps maximise energy efficiency, security and longevity.
Improved care and respect for your home
Because our fitters are long-term members of our team, they take pride in their work and the way they treat customers’ homes.
Homeowners often notice:
- Tidy working practices
- Respect for furnishings and flooring
- Clear communication during installation
This approach helps minimise disruption and stress during the installation process.
Better aftercare and long-term support
In-house fitters also play a key role in aftercare. If a customer needs adjustments or advice after installation, the same team is often involved.
This provides:
- Continuity of service
- Faster resolution of issues
- Greater confidence in long-term support
As a local Oxford company, we are invested in maintaining our reputation and relationships with customers.
Why this matters for Oxfordshire properties
Oxfordshire homes range from period terraces and cottages to modern developments. Each property type presents different installation challenges.
Our in-house fitters:
- Understand local property styles
- Adapt installations to suit older buildings
- Ensure modern performance without compromising appearance
This local experience is invaluable when working on varied housing stock.
