From start to finish my dealings with Mark and Jordan at Landmark Windows were smooth and straightforward. I believe they really care about their product and service. I would highly recommend them.

Missing evidence lowers the score because we can't check it. It doesn't mean it doesn't exist. Claiming a profile never changes the score. Evidence context, not a guarantee of workmanship.

Detailed reviews
These are the individual reviews we hold for Landmark Window Systems, including the highlights above. The 110 headline total is the review volume reported across public review sources.
We were impressed with the work which Landmark did for us. Initially we had a new front door. Mark had done all the measurements and gave us a date for the fitting. The guys did a lovely job and were pleasant and polite. We decided to replace an old sliding door on the side of the house with a new door and glass panel. Again it was measured up and fitted on the date agreed. We would recommend Landmark to others. They are a local firm and we found them very helpful and obliging. We would definitely use them again if we need anything done.
From start to finish Landmark were excellent. Mark explained the process clearly and the office were excellent in keeping me informed of timing and payment schedule. The surveyor and the guys who did the installation were all excellent - friendly and efficient. They even took down and put back up some very heavy long curtains for me which was not part of the job. We were extremely happy with the work and the new doors are brilliant. Thanks again Landmark.

Official checkOn the public register
Why this helps you judge trust: this trader is linked to a registered company with named people who are legally accountable for it, on an official register anyone can check, a layer of accountability an unregistered trader doesn't offer. Around 22 years on the register also points to an established business rather than a brand-new one.

What to check before you hire
Worth checking yourself
Always confirm credentials and quotes with the business directly before hiring.
Be wary of high-pressure 'today-only' discounts and a salesperson who won't leave. A reputable window or door firm gives you a written, itemised quote you can take away and compare against others.
Never pay the full price up front; a modest deposit with the balance on completion is normal. Ask what deposit protection or insurance-backed guarantee you get if the firm stops trading before fitting.
Get the specification in writing (frame material, the glazing units and their energy rating, and any trickle vents) so you can check you got what you paid for.
