FAQ
What is the structural advantage of a sliding patio door over a bifold door?
Sliding patio doors feature significantly larger panes of glass and much narrower vertical frames than bifold doors. This means that when the doors are closed, you get an almost entirely uninterrupted view of your garden with far less structural profile blocking your sightline. Additionally, because sliding doors glide parallel to each other on an inline track, they do not require any internal or external "stacking" space, making them ideal for properties with compact patio or balcony layouts.
Do I need planning permission to replace patio doors in Eynsford?
Replacing existing patio doors or upgrading standard rear windows to a sliding door typically falls under Permitted Development rules and does not require formal planning permission. However, because large swathes of Eynsford sit within a highly protected conservation area and the Green Belt overseen by the Sevenoaks District Council, special rules apply to listed buildings or front-facing alterations. Our local team can help advise you on local guidelines.
Are modern sliding patio doors easy to break into?
Absolutely not. Older sliding doors had historical vulnerabilities, but our modern systems are built to meet strict security standards. They are engineered with advanced anti-lift blocks that stop the doors from being pried out of their tracks, coupled with high-security multi-point locking mechanisms and impact-resistant safety glass as standard.
Can I get a flush threshold for my sliding doors?
Yes. If you are building a new extension or undertaking a major open-plan renovation, we can install a low-threshold track that sits nearly flush with your flooring. This creates a completely seamless, trip-free transition between your interior living space and your outdoor garden patio.

"We had our old, heavy patio doors replaced by Future Double Glazing and we couldn't be happier with the result. The new sliding doors move so effortlessly and the room feels instantly warmer and completely draft-free. The installation team was fantastic—very polite, tidy, and finished the work right on schedule. Highly recommend this local company to anyone in Eynsford!"
