Glazora Commercial
Better fenestration decisions start before the tender goes out.
Independent product, supplier and commercial expertise for organisations procuring windows and doors at scale.
The problem
Buying windows and doors at scale is not the same as buying one set.
Programmes of this size run into problems that a single domestic quotation never has to solve.
Specifications written by suppliers
Many specifications originate from the manufacturer that stands to win the work, which makes genuine like-for-like comparison difficult from the outset.
Tenders that are hard to compare
Quotations arrive in different formats, referencing different systems and performance figures, making it hard to know if you are comparing equivalent products.
Whole-life cost vs capital cost
The lowest tender price does not always reflect the lowest cost over a building's life once maintenance, servicing and expected lifespan are considered.
Compliance and security standards
Fire, security and accessibility requirements vary by building type and tenure, and need to be checked against the specification rather than assumed.
Resident and occupant disruption
Replacement programmes on occupied buildings need sequencing and communication that a purely commercial supplier relationship rarely accounts for.
How we help
Support at the stages that matter.
Procurement Support
Independent input into how a procurement route and specification are structured before it goes to market.
Product/System Evaluation
Guidance across PVC-U, aluminium, timber and composite systems, matched to your building type and constraints.
Supplier/Fabricator Review
Independent market insight when evaluating potential suppliers or fabricators — with no supply agreement to defend.
Tender Support
Putting competing quotations and tenders on a consistent basis so you can see what is genuinely being offered.
Specification Review
Reviewing a draft or existing specification so it describes the outcome you need rather than a single manufacturer's product.
Value Engineering
Identifying where cost can be taken out of a specification without compromising the requirement it was written to meet.
Market Testing
An independent check on whether pricing and proposals received reflect what the wider market would offer.
Who we work with
Built for the people who specify and procure, not just the people who occupy.
Local Authorities
Housing stock replacement and refurbishment programmes that need defensible, comparable specifications.
Housing Associations
Planned and reactive fenestration works across managed stock, with resident impact to consider.
Developers
New-build and refurbishment specification decisions made early, when they are cheapest to get right.
Main Contractors
A second opinion on fenestration packages before they are built into a wider programme.
Asset Managers
Ongoing stock condition, servicing and replacement planning for windows and doors.
Procurement Teams
Independent input at the stage where the requirement and specification are still being shaped.
Architects/Specifiers
An independent check on product selection where the brief calls for options beyond a single system.

The limits of our advice
What Glazora Commercial does not do.
