Why you should choose KJM in a crowded market-place?

When you’re investing in new double or triple glazing, you don’t need national hype—you need a proven local installer that will still be here in 10 years.

In a marketplace crowded with aggressive national chains and “here today, gone tomorrow” fitters, KJM Windows & Conservatories stands apart. Having traded continuously since the early 1980s, our reputation is built on simple principles: do the job right, treat people fairly, and stand behind every installation.

1. 40+ Years of Continuous Trading

Stability matters when buying products designed to last decades. Many window companies offer “10-year guarantees” but close down and restart under a new name long before that decade is up.

KJM has delivered thousands of installations across Andover and Hampshire since 1983. We remain proudly independent, locally accountable, and financially stable.

2. Local Trust vs. National Hype

How does KJM compare to the typical national installer? We believe in transparency. One of our biggest differences is how our team is paid.

As one customer notes in the video below: “Their salesmen are salary based… no one tried to push me into anything.”

3. Hear it from our Customers

We don’t just claim to be good; independent platforms and our own customers verify it. Watch this recent testimonial from a customer who trusted us with their Windows, Doors, and Conservatory Roof:

4. Employed Installers, Not Sub-Contractors

We use trained, directly employed fitters—some with decades of service at KJM. This is crucial for two reasons:

• Consistency: You get the same high standard of workmanship every time.
• Respect: As mentioned in the video above (“Cleanliness beyond clean”), our teams respect your home, using dust sheets and cleaning up after themselves.

5. Verified Standards, Not Just Claims

Anyone can build a website and claim to be the best. We back it up with verified accreditations:

• Which? Trusted Trader verified.
• GGF (Glass & Glazing Federation) member adhering to strict codes of practice.
• Trading Standards Approved (Buy With Confidence).
• Trustmark Registered.

6. Local Service, National Choice

From high-performance windows and doors to complex conservatories and roof replacements, we are not tied to a single manufacturer.

This means we pair the right product to your property—not the other way around. Whether you need the heritage look of Timber, the slim lines of Aluminium, or the efficiency of uPVC, we have the solution.
