Vertical Sliding Window Replacement Medway
Traditional-looking vertical sliding windows with the benefits of modern glazing, improved security and better energy efficiency – professionally installed across Medway and surrounding Kent areas.
Traditional Style With Modern Window Performance
Hi, I'm Tim from TS Glazing. Vertical sliding windows are a great option for homeowners who want to keep the traditional character of their property while benefiting from modern glazing technology.
They replicate the appearance of traditional sash windows, with vertically proportioned frames and glazing bars, but modern versions offer significantly improved thermal performance, security and ease of maintenance.
At TS Glazing, we provide professional vertical sliding window replacement across Medway for homeowners replacing ageing timber sash windows or older window installations.
With more than 25 years of hands-on glazing experience, I personally carry out our window installations and make sure every replacement is fitted, aligned, insulated and sealed correctly.
What Are Vertical Sliding Windows?
Vertical sliding windows are designed to recreate the classic appearance associated with traditional sash windows.
Their tall proportions, horizontal meeting rail and optional Georgian-style glazing bars make them particularly suited to Victorian, Edwardian and other character properties.
Modern vertical sliding windows can provide the appearance of a traditional sash window while incorporating contemporary double-glazed units, modern locking systems and improved seals.
This makes them a popular choice where homeowners want to retain the style of an older property without continuing to live with draughty, difficult-to-maintain or inefficient old windows.
Replacing Two Older Vertical Sliding Windows
This recent project involved replacing two ageing vertical sliding windows positioned one above the other on the front of the property.
The existing windows suited the character of the brick building, so the aim wasn't to dramatically change the style of the house. Instead, the customer wanted new windows that kept those traditional proportions while improving the overall condition and performance of the glazing.
We replaced both units with clean white PVC vertical sliding windows featuring glazing bars that retained the traditional look of the originals.


“The important thing on this job was keeping the character of the property. Putting a completely different style of window into these openings wouldn't have looked right. The new vertical sliders give the customer the traditional appearance they wanted, but with the benefits of a modern installation.”
Tim – TS GlazingBenefits Of Replacing Older Sash-Style Windows
Better Insulation
Modern glazing and improved seals can help reduce unwanted heat loss and cold draughts.
Improved Security
Modern locking systems offer greater security than many ageing window installations.
Traditional Appearance
Vertical proportions and glazing bars help preserve the character of older properties.
Lower Maintenance
Modern PVC frames require far less maintenance than ageing painted timber windows.
How We Replace Vertical Sliding Windows
A replacement window needs to look right, but the work hidden around the frame is just as important as the finished appearance.
Measure
The existing opening is carefully measured so the new window can be manufactured to the correct dimensions.
Remove
The old window is carefully removed while protecting the surrounding brickwork and internal finishes.
Install
The replacement window is levelled, secured and adjusted so it operates correctly.
Insulate & Seal
The surrounding gaps are properly insulated and the installation is professionally sealed inside and out.
Why The Installation Matters As Much As The Window
Even a high-quality replacement window won't perform properly if the installation around it hasn't been completed correctly.
When replacing older windows, I regularly come across issues such as poorly insulated openings, deteriorated sealant or frames that weren't installed square in the first place.
That's why I inspect the opening once the original window has been removed rather than simply dropping the new frame into the same space and assuming everything underneath is fine.
- Frame checked for level and alignment
- Opening inspected after old window removal
- Correct insulation applied around the frame
- Window operation and locks tested
- Internal and external edges professionally sealed
The same approach applies throughout our double glazing installations in Medway .

What is a vertical sliding window?
A vertical sliding window is a sash-style window designed with vertically proportioned sections and a horizontal meeting rail. Modern versions recreate the appearance of traditional sash windows using modern glazing and frame systems.
Can old timber sash windows be replaced with PVC versions?
In many properties, yes. Modern PVC vertical sliding windows can provide a similar traditional appearance while reducing maintenance and improving thermal performance.
Do vertical sliding windows have double glazing?
Modern vertical sliding windows can be supplied with energy-efficient double-glazed units, giving them a significant performance advantage over many older single-glazed sash windows.
Are vertical sliding windows suitable for older properties?
They are particularly popular for traditional and period-style properties because their proportions and glazing-bar options can complement older architecture.

Yes. TS Glazing provides window replacement and repair services throughout Hempstead, Gillingham, Rainham, Chatham, Rochester, Strood and surrounding Medway areas.

Yes. If a repair is appropriate rather than full replacement, we'll tell you. Our approach is always to recommend the work the window actually needs rather than automatically replacing it.
