Replacement Doors & Bi-Fold Doors

As a highly regarded door company with nearly 20 years of experience, 3SG has replaced hundreds of doors in Olney for domestic and commercial customers. Our industry leading doors guarantee contemporary styling, high quality security features and an unrivalled installation service. No matter what type of exterior door you’d like to replace, whether it be a traditional wooden front entrance door, a set of steel French doors, an aluminium glazed backdoor or uPVC fold and slide doors, we can help you choose a replacement that delivers on safety, security, style and thermal efficiency.

Buckinghamshire is famous for its historic market towns and Olney is a fine example with a mix of period style buildings, classic high street shops, contemporary apartments, new builds and glorious character homes in the countryside. With this town being our home and one of our main locations, we’ve been lucky enough to replace doors for every kind of property.


What are the benefits of Bi-fold doors?

We’ve witnessed the introduction and rise of bi-fold doors, and in that time we have grown to become a specialist supplier. So, why are these doors becoming so popular for properties in Buckinghamshire and the rest of the UK?

One of the big benefits is that they allow you to integrate your outdoor space with your living space. You’ve probably heard of the saying “bringing the outdoors in” and that’s exactly what these doors can do for you, especially in spring and summer. There’s something quite special about unwinding in your home with the doors wide open, as fresh air spreads throughout your home.

These doors can be just as blissful in the winter months too, as you’re able to snuggle up in the warm as you watch a downpour of heavy snow or rain! If you’re considering bi-fold doors for your home in Bucks, it’s important to know that you also get a tremendous amount of light with the full height glazed panels, helping the light flood into your room, even on particularly dull or dreary days.

We can install bespoke bi-fold door systems for your kitchen, living room, dining room, orangery or conservatory to provide a pleasant transition to your garden. These will not only look stunning but they’re incredibly strong and flexible enough for runs of up to 15 metres wide and 3 metres high, and they’re available in a variety of finishes. The majority of our customers choose these doors for their patio because they’re looking for a contemporary door that’s easy on the eye, smooth to operate, energy efficient, solid and secure, all thanks to a multipoint locking system.
