About Absolute Window Co
A Manchester manufacturer and installer with over 25 years of experience and thousands of satisfied customers.
Built on Quality, Driven by Manchester
Absolute Window Co was founded in 2005 with a simple belief: that Manchester homeowners and businesses deserve better — better products, better installation and better aftercare — than the national chains could offer.
Starting with a small team and a workshop in the heart of Greater Manchester, we've grown into one of the region's most trusted window and door companies, completing over 15,000 installations without ever losing sight of the values that set us apart.
Unlike many of our competitors, we manufacture our own products in-house. We've invested over £500,000 in state-of-the-art fabrication machinery at our Worsley facility — giving us tighter quality control at every stage, faster turnaround times, and the ability to offer truly bespoke solutions that factory-standard installers simply cannot match.
Our Values
Quality Without Compromise
We use only the highest-grade materials and will never cut corners. Every product leaves our factory meeting or exceeding industry standards.
Honest & Transparent
No hidden costs, no pressure selling, no false discounts. We give you a fair price for quality work and stand behind every quote we provide.
People First
Whether it's a customer waiting for a callback or an employee seeking support, we treat everyone with respect. Our team have some of the longest service records in the industry.
Proud to be CERTASS Registered
CERTASS is the leading Competent Person Scheme for the fenestration industry in the UK. As a CERTASS registered installer, every window, door and conservatory we fit is:
- Installed to current Building Regulations standards
- Issued with an official compliance certificate
- Covered by consumer protection
- Inspected and audited by independent assessors
This means you can buy with complete confidence and use the certificate when selling your property.
Alongside CERTASS we're also Checkatrade approved, TrustMark certified and members of the Federation of Master Builders — independent assurance on every installation.
