We oversee the seamless coordination between clients, suppliers, and installers. Our goal is to make the process of ordering windows and doors as efficient, transparent, and hassle-free as possible. Whether you're a homeowner, contractor, or developer, our system is designed to provide you with premium products, clear communication, and reliable delivery. Here’s how our ordering process works in 5 simple steps:
The process begins with understanding your needs. Whether you have architectural drawings, rough measurements, or simply a vision, our team is here to help. Clients can submit their project details through our online form, via email, or by speaking with one of our product advisors.
We assist in identifying the right product type – uPVC, aluminium, timber, or composite.
Our experts help choose styles, glazing options, finishes, and hardware that meet performance and aesthetic requirements.
Within 24–48 hours, we provide a detailed quotation including product specifications, lead times, and pricing.
Once the quote is approved, the order is formally confirmed and entered into our system. We work directly with a trusted network of UK and European manufacturers to source your windows and doors at competitive prices.
Our team reviews the order to ensure technical accuracy and compliance with UK building regulations.
Detailed order confirmations and drawings (if applicable) are sent to the client for final approval.
After sign-off, the manufacturing order is placed with the supplier, and production timelines are shared.
Our suppliers begin production based on your approved specifications. Throughout this phase, we maintain close contact with the factories to monitor progress and perform quality assurance.
Each product goes through a strict quality control process before dispatch.
If your order includes custom or large-scale items, we provide regular updates and coordinate site readiness checks if needed.
We ensure all products meet British Standards and CE/UKCA certification.
Once the products are manufactured, we arrange delivery directly to your site or preferred address. Logistics are managed by our in-house coordination team to guarantee a smooth handover.
Delivery dates are confirmed in advance and aligned with your project schedule.
We offer kerbside delivery, offloading assistance, or direct-to-installer options.
All deliveries are tracked, and any damage or discrepancies are handled swiftly.
If required, we can connect you with one of our approved installers in your region. We also provide post-delivery support for all clients, ensuring satisfaction beyond delivery.
Our installers are vetted, experienced, and trained on our products.
We offer installation guidance, technical support, and warranty registration assistance.
Any post-installation issues or warranty claims are handled by our dedicated aftersales team.
At Critalu, we don’t just supply windows and doors – we manage the entire process from consultation to completion with professionalism and precision. Whether it's a single home renovation or a large commercial project, our goal is to deliver the right product, on time, every time.
