Many uPVC window options
Casement Windows: The Practical Choice
For the majority of homes in Romsey—especially the 1970s and 80s properties in Whitenap and Halterworth—our uPVC casement windows are the perfect upgrade. We use the market-leading Profile 22 system, which is designed to be slim, strong, and incredibly thermally efficient.
Unlike older double glazing which can fail and mist up, our casement windows achieve an A+ Energy Rating as standard. They feature multi-chambered frames that trap heat and high-security multipoint locking, making your home warmer and safer instantly.
Flush
Heritage “Flush Sash” (Conservation Friendly)
If you live closer to Romsey Abbey or in a conservation area, standard uPVC frames are often not allowed because they look too “plastic.” Our Flush Sash windows are different. The opening part of the window sits flush within the frame—mimicking the clean lines of 19th-century timber joinery.
When finished in a realistic woodgrain foil (like Agate Grey or Irish Oak) with mechanical joints, they are virtually indistinguishable from real wood. This makes them one of the few uPVC windows often approved by planning officers in the Test Valley.

Vertical Sliding Sash Replacement
Many of the Victorian and Edwardian terraces in Romsey town centre still suffer from draughty, rattling timber sash windows. Our uPVC Vertical Sliders allow you to retain that classic period charm without the constant maintenance of sanding and painting.
They come with authentic details like run-through sash horns, deep bottom rails, and decorative Georgian bars—but with modern engineering. A clever “tilt” function allows you to clean the outside glass safely from the inside, solving a major headache for homeowners.

Frequently Asked Questions
In many cases, yes. While Romsey town centre (especially near the Abbey) has strict planning rules, modern "Flush Sash" uPVC windows are often accepted because they mimic traditional timber joinery so closely.
For Grade II listed buildings, restrictions are tighter. We have extensive experience working with the Test Valley Borough Council planning department and can advise you on whether our Residence 9 or Heritage ranges would be suitable for your property.
Condensation is a common problem in the 1970s and 80s properties found in areas like Whitenap and Woodley. It occurs when warm, moist air hits cold glass.
Our uPVC windows are rated A+ for energy efficiency. They feature "warm edge" spacer bars and Argon gas-filled units, which keep the inner pane of glass much warmer. This significantly reduces the risk of condensation forming and helps eliminate that "chilly draught" feeling near the window.
Modern uPVC windows are vastly more secure. All KJM windows come with multi-point locking systems (securing the window at several points along the frame, not just the handle) and key-locking handles as standard.
Crucially, we use internal glazing beads. This means the glass can only be removed from the inside of the house, preventing intruders from simply removing the glass pane to gain entry.
