One of our team comes to you at a time that suits. We measure up, show you options, and answer every question. You are under zero obligation at this point.
A clear, itemised written quote within 24 hours of your visit. Exactly what's included, exactly what it costs. Take as long as you need — we never chase.
Our own fitting team arrives on time, works cleanly, and leaves your home as tidy as they found it. FENSA certificate included as standard.
The big glazing companies employ commission salespeople, use sub-contractors, and move on once the job is done. We don't. Here's what's different about Square Deals.
No hidden charges, no "upgrades" added on installation day. The written quote you receive is the price you pay. We've built our reputation on it for 28 years.
We never use sub-contractors. The people who quote your job are connected to the team who install it. That means real accountability — and someone to call if you ever need us.
Our team aren't on commission. When we recommend a product, it's because it's right for your home — not because it earns someone a bonus. That's how honest advice works.
Every installation comes with a free insurance-backed guarantee. In the unlikely event something ever happens to Square Deals, your installation is still fully protected.
Every installation is FENSA certified. Solicitors require this when you sell — without it, deals fall through. We handle it as standard, not as an optional extra.
A-rated double glazing reduces heat loss by up to 50% through your windows. For a typical York home, that's a meaningful reduction in heating costs — year after year.
