The Complete Window Replacement Service

Are your current windows letting you down? Over time, even the best window installations begin to fail. You might notice condensation forming between the glass panes, annoying draughts whistling through the frames, or a steady increase in your winter heating bills. Replacing your old, tired frames is one of the most transformative investments you can make — instantly modernising your home's exterior while making the interior dramatically warmer, quieter, and more secure.

At Homestyle Windows, based in Martlesham, we specialise in seamless, stress-free whole-house window replacements. We manage the entire process for properties across Kesgrave, Ipswich, Woodbridge, Felixstowe, and throughout Suffolk and Essex. We carefully remove your existing frames, causing minimal disruption to your decor, install your stunning new custom-made units, and complete all the essential 'making good' (internal trims and exterior sealants) so everything looks impeccable.

We only install industry-leading profiles from premium British fabricators, including Emplas (for UPVC & Flush styles), Victorian Sliders (for Vertical Sliding Sashes), and ALuK/Arkay (for slimline Aluminium). Every single replacement window is FENSA-certified and backed by our rock-solid 10-year installation guarantee.

Replacement Styles We Offer

Replacing your windows doesn't mean you have to stick with what you currently have. This is the perfect opportunity to upgrade your home’s character. Choose from the premium options below.

Cost-Effective & Versatile

UPVC Casement Replacements

The perfect, low-maintenance upgrade. Manufactured using the robust Emplas Profile 22 Optima system, our UPVC casement windows supply exceptional thermal efficiency (A-Rated glass as standard) and multi-point security. Available in crisp white or a huge variety of modern foils like Anthracite Grey to completely refresh your property facade.

Best for: Straightforward replacements offering maximum value, security, and an instant thermal upgrade.
Heritage Appeal

Flush Casement Replacements

A massive upgrade for period properties and modern homes alike. Flush casements sit perfectly level within their frames, mimicking traditional 19th-century timber craftsmanship. Our Emplas flush windows eliminate the bulky 'lip' of older UPVC, delivering sleek, clean lines alongside cutting-edge weatherproofing.

Best for: Homeowners wanting to inject traditional cottage character without the maintenance of real wood.
Modern & Architectural

Aluminium Replacements

The ultimate contemporary aesthetic. We supply premium ALuK windows fabricated by Arkay, featuring incredibly slim frames and expansive glass areas. With a robust polyamide thermal break, you get the chic, minimalist steel-look design without sacrificing any of the warmth you expect from modern double glazing.

Best for: Modernising a tired exterior, creating an architectural feel, or replacing 1980s aluminium frames.
Classic Elegance

Vertical Sliding Sash Replacements

Ideal for Victorian or Georgian homes plagued by rattling, draughty timber box sashes. We exclusively install the industry-leading ECOSlide system by Victorian Sliders. Get the authentic period look—complete with sash horns and astragal bars—with the benefit of smooth UPVC runners and an inward-tilting cleaning facility.

Best for: Period townhouses and conservation areas where preserving authentic timber styling is paramount.

Lead Times

Survey to Installation: 8–10 Weeks

Because every replacement window is completely made-to-measure for your specific apertures, our standard timeline from your final survey to installation averages 8 to 10 weeks.

Once manufactured, a typical whole-house window replacement is completed cleanly and efficiently within just 2 to 4 days by our expert fitters. Please note: Intricate Heritage Sash windows from Victorian Sliders can occasionally run to 10–12 weeks; we will always provide a firm, honest timeline at the quotation stage.

Frequently Asked Questions

How do I know it is time to replace my windows?
The most common signs that your windows need replacing include feeling draughts around the frames, noticing condensation or misting forming between the panes of double glazing (which indicates a failed seal), difficulty opening or closing the windows, or simply a noticeable increase in your heating bills as older frames lose their thermal efficiency.
Will there be much mess during the replacement installation?
No. Our fitting teams pride themselves on treating your home with the utmost respect. We use dust sheets to protect your floors and furniture, and we carefully remove the old frames to minimise any disruption to your surrounding plaster or brickwork. Once the new windows are fitted, we handle all the 'making good' (applying trims and sealants) and vacuum the area before we leave.
How long does the replacement process take?
From survey to installation, our average lead time is 8 to 10 weeks. Once the windows are manufactured and ready, the actual installation at your property typically takes between 2 to 4 days for a full house replacement, depending on the size of your property and the complexity of the job.
Can I change the style of my windows when replacing them?
Yes, absolutely! Window replacement is the perfect time to upgrade your home's aesthetic. You can swap standard casements for elegant Flush Casements, upgrade to modern Aluminium frames for slimmer sightlines, or switch to practical Tilt & Turn windows. We will discuss all your styling and configuration options during your free home survey.
Do I get a FENSA certificate for replacement windows?
Yes. We are a fully registered FENSA installer. When you have your windows replaced by us, we register the installation to certify that it fully complies with all current UK Building Regulations. You will receive your FENSA certificate in the post shortly after the job is completed.
What areas do you cover for window replacements?
We are based in Martlesham and provide complete window replacement services across all surrounding areas, including Kesgrave, Ipswich, Woodbridge, Felixstowe, Martlesham Heath, and throughout the whole of Suffolk and Essex.
Are your replacement windows guaranteed?
Yes. Every replacement window we supply and install comes with our comprehensive 10-year installation guarantee, covering both the frames and the sealed glass units.

What Our Replacement Customers Say

Reviews related to our window replacement service

Mark & Julie B. • Bury St Edmunds★★★★★

We had the whole house fitted with new replacement windows. The team removed the old rotten timber ones with barely any mess at all. The difference in warmth is unbelievable.

Colin R. • Colchester★★★★★

Homestyle replaced all of our 1980s aluminium windows with modern, thermally efficient profiles. The 'making good' inside was flawless. Superb service.

Helen T. • Ipswich★★★★★

Absolutely brilliant from start to finish. I was worried about the mess of replacing 12 windows, but they used dust sheets everywhere and vacuumed up each day.

Diane W. • Woodbridge★★★★★

Cannot recommend Homestyle enough. We replaced our standard UPVC with flush casements. The fitters were polite, tidy, and their attention to detail on the finishing trims is exceptional.
