Window installation services in Bristol

What Types of Windows Do You Offer?

At BS15doors, we offer a range of windows, including uPVC casement windows, flush casement windows, and sliding sash windows. All of our windows are made from modern materials and are energy-efficient.

Do You Offer Window Installation Services?

Can You Provide Custom Made Windows?

Yes, we can provide custom-made windows to fit your specific requirements. Simply let us know your preferences, and we will create windows that are tailored to your needs.

What Makes uPVC Windows a Great Choice?

uPVC windows are made from durable, weather-resistant polymer materials, ensuring that the frames will not fade, rot, or decompose over time. They provide excellent thermal insulation and can help reduce energy costs in your home. They are also available in a variety of styles and finishes to suit your aesthetic preferences.

These low-maintenance windows retain their high-quality finish and only require a simple wipe-down with a damp cloth to keep them looking pristine. With a typical lifespan of up to 30 years, uPVC windows provide long-lasting beauty and functionality for your home.

Are Your Windows Double-Glazed?

We offer double-glazing options for our windows, providing enhanced thermal insulation and noise reduction. Double glazing consists of two glass panes with a gap filled with an insulating gas, which helps to minimise heat transfer and improve energy efficiency in your home.

Do You Offer Triple Glazing?

Yes, we also provide triple-glazing options for customers who require even higher levels of energy efficiency and noise reduction. Triple glazing consists of three glass panes with multiple layers of insulating gas, which offers superior thermal performance. 

Our triple-glazing options can help you create a more energy-efficient and peaceful home environment.

Can I Customise the Delivery and Installation Time for Your Windows?

At BS15doors, we understand that customers have different requirements and timelines for their window projects. 

Whether you need off-the-shelf windows or bespoke made-to-measure products, we will work with you to provide accurate estimates for delivery, manufacturing, and installation times.

What Types of Doors Do You Offer?

We offer a wide range of external doors, including composite doors, aluminium bi-fold doors, uPVC French opening doors, uPVC patio sliding doors, and uPVC panel doors. These doors are available in various styles, colours, and finishes.

Are Composite Doors More Secure Than Other Types of Doors?

Yes, composite doors are known for their security features. They are made from a combination of materials, including wood, uPVC, and insulating foam, which provide sturdy construction and enhanced security.

What Are the Benefits of Composite Doors?

Composite doors offer the best of both worlds by combining multiple materials to create a stronger and more durable product. These doors are thicker, stronger, and longer-lasting than single-component doors. Composite doors not only enhance the security of your home but also add a touch of elegance.

Well what can I say about BS15doors.

Well, what can I say about BS15doors? Absolutely 100% would recommend these guys. From ringing them up I had someone come out to my house the next day to measure up who was very friendly and made me feel confident in my decision to go ahead with getting my doors supplied and fitted with this company.

Kelly Palmer

Really really happy with my new front door.

Really really happy with my new front door. Communication with Ruth along the way was very easy and she always replied promptly, and the fitters did a perfect job! The price was the cheapest I got too. Definitely recommend them.

Susie Howells

Smooth communication from initial consultation to final installation.

Smooth communication from initial consultation to final installation. Professional service, reasonable price, definitely recommend. We had our front door, three windows replaced by BS15doors, definitely coming back for the rest of windows, thank you!

Han Lynn

Would definitely recommend BS15doors.

Would definitely recommend BS15doors. The service was great, the product is great and the price was very competitive.

Mike Norman

Top service from start to finish.

Top service from start to finish. From measuring up to supply speed and fitting. Ruth and John both excellent throughout. Cheapest quote by a long way in my local area and quickest turnaround to get them fit too. Will definitely use again on my next renovation project.


Definitely worth getting a quote from them.

The guys who fitted did an excellent job, showing me issues that had been identified earlier and how they have dealt with them. Windows have now been in place for quite a few months now and we have had no issues with them through any of the storms we have recently had.

Colin Gimblett

Fantastic service from start to finish.

They listened to what I needed, made suggestions and generally supported and kept me informed throughout. They turned up when they said the would with a quick efficient team who were in and out in less than 3 hours. New front door, overhead canopy and two windows! Great price too. We had quotes from other firms. But they lacked the customer service and personal touch that BS15doors gave.

A Peters

Great experience from initial enquiry to installation!

Ruth and John delivered a personal and instructive service and the door looks great. The chaps who installed it were friendly, professional and neat and tidy also and to top it all they offer competitive prices and good customer service too. Would recommend.
