How long does uPVC window installation usually take?

Most installations take between one and three days, depending on the number of frames and the condition of your existing windows. Our installers work efficiently while maintaining a clean, safe environment.

What's the difference between double-glazed and triple-glazed windows?

Double glazing includes two panes of glass with a sealed air gap, while triple glazing adds a third pane for increased insulation and noise control. Both options are energy efficient, but triple glazing offers enhanced performance for colder or high-traffic areas.

Can I get made-to-measure uPVC windows for older or heritage properties?

Yes. Our made-to-measure uPVC windows can be customised to suit heritage homes, including flush casement styles, woodgrain finishes and traditional glazing bars.

Do new windows help reduce energy bills?

High-quality modern windows use insulated sealed units and advanced glazing technologies that help reduce heat loss. This can lower heating demand and reduce household energy costs over time.

What colour options and woodgrain finishes can I choose from?

We offer a wide palette including white, anthracite, black, cream and a range of realistic woodgrain finishes. Bespoke colour matching is available for certain products.

Are your windows low-maintenance and weather-resistant?

Yes. Our uPVC and aluminium frames require minimal upkeep and are designed to withstand UK weather conditions without warping, fading or peeling.

Do you replace sealed units without changing the whole frame?

If your frames are still in good condition, we can replace the sealed units only — an affordable alternative to full replacement windows.

What security features do your windows come with?

All windows include reinforced locking systems, high-security hinges and durable frames tested for impact resistance.

What guarantees come with the installation?

Every installation includes a manufacturer warranty on frames and glazing, along with our workmanship guarantee for added peace of mind.

Do you offer both supply-only and supply-and-installation services?

Yes. We supply windows nationwide and also provide a complete supply and fit service for full home improvement projects.

We've used Secure Trade previously for our windows and were very happy with the price and quality of work. We recently had quotes for a new front door and porch doors, Jason talked us through the options for replacing both sets of doors and in the end we went with Jason's recommendation to remove the porch doors completely and replace just the front door. The fitters were professional and have done a great job, we're well pleased with the result.

Really good experience from start to finish. Survey and quotation completed quickly. Great communication on design and advice around what style, fittings and doors would work for us.

Everyone we met was punctual, polite and took time to explain the process and answer questions.

The fitters were top notch. They worked with us to get things done properly, allowing us time to think and plan around other tasks.

They took a lot of pride in getting things just so and the banter was genuine and funny especially whem they were cleaning up.
Which they did each day and made sure we were always left secure and safe.

When there were issues they took responsibility for getting it sorted. No need for us to chase or complain. A unit damaged in transit was replaced within 4 days.

Great from start to finish - thankyou Jason, Rob and Eric.

Jason was very helpful and made the entire process very easy. The fitters were very friendly and professional. I would certainly recommend.

We recently had new windows fitted by Secure Trade Frames. I couldn’t be happier with the results. From start to finish, the service was professional, reliable, and stress-free. Jason and Denise’s responded promptly to all my queries, Rob was punctual, tidy, and clearly takes great pride in his work.

The windows are of excellent quality and the installation was completed to a very high standard. Everything was left clean and tidy afterwards, and Rob took the time to make sure we were completely satisfied before leaving.

I would highly recommend Leicester Secure Trade Frames to anyone looking for new windows – fantastic workmanship and great value for money. Thank you again!

We had a new front door fitted and super happy with it. We’d been debating a new door for a while as the original one on our new build (10 years ago) has always been drafty. So Jason came over, measured up, got a quote, wasn’t pushy. WE LOVE IT. Chap that fitted it was great, so conscientious and did a fab job. Would def have these over to fit windows too. Thanks 🙂

We recently had all of our old box sash single-glazed windows removed and replaced with uPVC double glazing, along with having our back door replaced. From start to finish, the whole process was smooth and well organised.
The fitters arrived on time, were polite and professional throughout, and clearly took pride in their work. They worked efficiently and made sure everything was fitted properly, and they also kept disruption to a minimum. Once the job was finished, they left the house clean and tidy, which we really appreciated.
We’re extremely pleased with the quality of the windows and door and have already noticed the difference they’ve made. Overall, it was a great experience and we wouldn’t hesitate to recommend Secure Trade Frames to anyone considering new windows or doors.

I recently had patio doors fitted by Secure Trade Windows and the service was excellent from start to finish. Communication was clear and helpful throughout, the team arrived on time, and the installation was carried out to a very high standard. The fitters were professional, polite, and left everything clean and tidy. The doors look amazing and are great quality. I’m extremely pleased with the result and wouldn’t hesitate to recommend Secure Trade Windows to anyone.

We had STF to replace most of windows and doors. It was a very professional service and the quality of the products were excellent. The workmanship was great and they took away the windows they took out. They cleaned up after themselves and were respectful and polite. Out of 3 quotes they came in the most competitive for a premium product.
We will definitely use them again for our bifolds when we renovate our kitchen.

Jackie Beattie

We had new windows to the front of the house and modern black framed french doors, leading out to the conservatory, all made and fitted by Secure Trade frames.
The quality was exceptional and the fitters were professional, clean and fit everything to a high standard.
We would definitely recommend them!

We had a fantastic experience with Secure Trade Frames from start to finish. By far the cheapest of the four quotes we had and by far the best attention to detail, personal attention and service. We had a replacement front door and window, replacement back door and replacement French doors. The finish is excellent and we couldn’t be more pleased.

I can't rate Secure Trade Frames highly enough, we had an awkward job that needed doing in a tight timeframe and Jason and his team came through to get the job done with no issues whatsoever! I would highly recommend these guys.

Steve Plant

I required urgent attention to the locking mechanism on my front door and contacted Secure Trade Frames online. They were very quick to get back in touch and an appointment was made with a clear estimate of what the costs would likely to be, based on a couple of options regarding potential faults. I had to change the agreed time at short notice but they re jigged their arrival to fit in with my availability. On arrival the work was completed efficiently and in a cheerful manner. Payment went just as well via card across the phone. In short from the initial contact to final payment the process was smooth and trouble free - would certainly use again and recommend - Steve Plant

From the quote to the installation I can not fault the team. Jason is a great contact in terms of need, Lewis and partner arrived, carried out the work, on time, polite, clean and work was on point. Denise was overseeing everything. Would highly recommend this team

Most uPVC window installations are completed within one to three days, depending on the size of the project and the condition of the existing frames. Smaller jobs, such as replacing a few windows, can often be completed in a single day, while full-house installations may take slightly longer. At Secure Trade Frames, every installation starts with a detailed survey to ensure all windows are manufactured to precise measurements before fitting begins. This helps reduce delays and keeps disruption to a minimum. The installation team also removes old frames carefully, fits the new windows securely, seals everything properly, and leaves the property clean and tidy once the work is complete.

Double-glazed windows use two panes of glass separated by an insulated gap, while triple glazing adds a third pane for even greater thermal efficiency and sound insulation. Both options are designed to reduce heat loss, improve comfort, and increase energy efficiency throughout the home. Double glazing is often the most popular choice for UK homes because it provides excellent insulation and value. Triple glazing is ideal for homeowners looking for enhanced thermal performance, quieter indoor spaces, or improved efficiency in colder areas of the property. Secure Trade Frames supplies A-rated energy-efficient glazing systems designed to help reduce draughts, improve indoor temperatures, and lower heating costs over time.

Yes. Made-to-measure uPVC windows are an excellent solution for older homes, cottages, Victorian terraces, and heritage-style properties. Modern uPVC systems can be customised to replicate the appearance of traditional timber windows while providing all the benefits of modern glazing technology. Options such as flush casement windows, sash horn designs, traditional glazing bars, and realistic woodgrain finishes allow homeowners to maintain the original character of the property without the maintenance issues associated with timber frames. Secure Trade Frames offers bespoke window styles specifically designed to complement both period and contemporary homes while improving insulation, comfort, and security.

Yes. Older or poorly insulated windows can allow a significant amount of heat to escape from the home, making heating systems work harder throughout the year. Modern A-rated windows are designed with insulated sealed units, advanced glazing technology, and energy-efficient frames to help retain warmth more effectively. Replacing outdated windows with modern double or triple glazing can improve thermal performance, reduce draughts, and create a more comfortable indoor environment. Many homeowners also notice lower heating costs over time due to improved energy efficiency. Secure Trade Frames supplies energy-saving windows designed to reduce heat loss while improving long-term comfort and performance.

Modern uPVC windows are available in a wide range of colours and finishes to suit both traditional and contemporary homes. Alongside classic white frames, homeowners can choose from popular shades such as anthracite grey, black, cream, Chartwell Green, and woodgrain finishes including Golden Oak, Rosewood, Walnut, and Irish Oak. Woodgrain foils are designed to recreate the appearance of real timber while remaining low-maintenance and weather-resistant. Many finishes are available internally and externally, allowing homeowners to create a bespoke look that complements the character of their property. Secure Trade Frames offers more than 40 colour options, including bespoke RAL colour matching for selected products.

Yes. Modern uPVC and aluminium windows are specifically designed to handle changing UK weather conditions while requiring very little upkeep. Unlike traditional timber frames, they do not rot, warp, peel, or require regular repainting. Routine maintenance is usually limited to occasional cleaning with warm soapy water and checking hinges or locks periodically. The durable finishes are designed to remain colour stable and resistant to fading, even after years of exposure to wind, rain, and sunlight. Secure Trade Frames supplies high-quality window systems built for long-term performance, durability, and everyday reliability.

Yes. If the existing frames are still structurally sound, it is often possible to replace only the sealed glass units instead of installing completely new windows. This can be a cost-effective solution for homeowners experiencing condensation between panes, misted glass, or reduced insulation performance. Replacing sealed units can restore clarity, improve energy efficiency, and extend the lifespan of your existing windows without the expense of a full frame replacement. A professional survey can determine whether the frames are suitable for this option.

Modern uPVC and aluminium windows are built with security in mind and include a range of protective features designed to improve home safety. These commonly include multi-point locking systems, reinforced frames, secure hinges, toughened glazing options, and impact-resistant hardware. Many modern systems are also internally beaded, making it far more difficult for glass panels to be removed from outside the property. Combined with professional installation, these features help improve both security and peace of mind for homeowners. Secure Trade Frames installs windows designed to meet modern security standards while maintaining a clean and stylish appearance.

Secure Trade Frames provides comprehensive guarantees on both products and installation work for added peace of mind. Supply and fit installations include a 10-year warranty covering parts and labour, alongside additional insurance-backed protection. For supply-only products, guarantees are available on sealed units, mechanical components, and profile durability, subject to installation requirements being met. These warranties are designed to give homeowners confidence in the long-term quality and performance of their new windows and doors.

Yes. Secure Trade Frames offers both supply-only products and a full supply-and-fit installation service. This gives homeowners, builders, and trade customers the flexibility to choose the option that best suits their project. Supply-only windows are ideal for builders, developers, or customers arranging their own installation, while the full installation service includes surveying, manufacturing, fitting, and aftercare support from experienced specialists. All products are made to measure and designed to deliver long-lasting energy efficiency, security, and performance.
