Finding reliable window fitters in London can feel like a daunting task. There are countless companies to choose from, and it’s not always easy to tell who you can trust with such an important investment in your home.
At Aim Windows, we’ve built our reputation on honest service, quality products, and skilled installation across East London and beyond. Whether you’re looking to replace windows, upgrade your front door, or add a conservatory, we’re here to help you make the right choices for your property.
Our Range of Windows
Casement windows are the UK’s most popular style. They’re the classic design you see throughout London, practical, secure, and available in over 30 different colours. If you’re after something with a bit more character, our flush sash windows give you that traditional look without sacrificing modern performance. The sashes sit flush with the frame, creating a beautifully flat finish.
For homes in conservation areas or listed buildings, sliding sash windows are often the go-to option. These vertical sliders capture the Georgian and Victorian aesthetic that’s so common across London, and our modern versions come with all the thermal efficiency and security features you’d expect from new window installation.
For a unique architectural feature and improved internal space, we offer bay & bow windows. These windows expand out from your property, creating a mini seating area and expanded views.
Tilt & turn windows are a unique, dual-purpose style that is growing in popularity. They feature the ability to tilt inwards from the top for secure ventilation, and turn open fully from the inside, allowing easy cleaning, perfect for high-rise flats.
uPVC Windows
Our uPVC windows remain one of the most popular choices among London homeowners, and it’s easy to see why. They offer excellent energy efficiency without breaking the bank, making them ideal for families looking to reduce heating bills while improving comfort at home.
We work with two of the industry’s leading manufacturers, Eurocell and Rehau, to bring you windows that perform brilliantly year after year. With proper care, you can expect our windows to improve your home for up to 35 years with minimal maintenance.
Aluminium Windows
If you want slim frames and maximum glass, aluminium windows are a great choice. The material’s natural strength means we can create larger panes with narrower sightlines, flooding your rooms with plenty of natural light.
Our aluminium range comes from Smart Architectural Aluminium, a name that’s respected throughout the UK for quality and innovation. These windows feature advanced thermal break technology that stops cold transfer through the frame, keeping your home warm in winter.
All our aluminium windows can be finished in any RAL colour you like, giving you complete control over your home’s appearance.
Our Doors
Composite Doors
When it comes to front doors, our composite options are hard to beat. They’re built with a solid core that provides strong security and excellent energy efficiency.
We offer door installations from three respected manufacturers: Doorstop, Virtuoso and Endurance. This gives you over 50 designs and countless colour combinations to pick from, no matter if you prefer traditional or modern designs.
uPVC and Aluminium Doors
Our doors aren’t limited to front entrances. We supply and fit back, sliding patio, bifold, and French doors in both uPVC and aluminium. All our doors are supplied by market-leading manufacturers and installed by our expert team.
Our Conservatories
Adding a conservatory remains a popular and effective way to create extra living space without the upheaval of moving house. We offer five classic styles:
- Lean-to conservatories – Simple, affordable, and perfect for smaller properties
- Victorian conservatories – Feature a distinctive curved bay front with decorative detailing
- Edwardian conservatories – Square or rectangular with clean, symmetrical lines
- Gable-end conservatories – Grand triangular roofs that capture the light
- Bespoke conservatories – Designed entirely around your specific needs and vision
All our conservatories use either uPVC or aluminium frames, and we can top them with a modern roof lantern.

Frequently Asked Questions
How long does a typical window installation take?
Most standard window replacements can be completed in just one to two days, depending on the complexity of the job and how many windows you’re having fitted. We’ll give you an accurate timeframe during your consultation so you can plan accordingly.
Can you match the style of my existing windows?
Absolutely. If you’re replacing just some of your windows and need to match existing ones, we can replicate colours, styles and configurations very accurately.
How do I maintain my new windows?
One of the benefits of modern uPVC and aluminium windows is that they need very little maintenance. An occasional wipe down with soapy water is usually sufficient.
