At Mike Martin Windows, we’ve spent nearly 39 years growing our business, building our award-winning team, and completing over 700 projects every year. We’ve achieved this by focusing on quality, craftsmanship, and customer care—not by rushing lead times to meet unrealistic deadlines.
We know that when you’re planning a home improvement or construction project, you want things to happen as quickly as possible. Whether you’re replacing your windows and doors or working on a new build or renovation, lead times are an important part of the process.
That’s why we want to be completely upfront about how long things can take and why early planning is key.
Why Do Window and Door Lead Times Vary?
Unlike standard retail purchases, windows and doors are custom-made to suit your specific project. Because of this, lead times can fluctuate due to a variety of factors:
✅ Bespoke Manufacturing – Every window and door is tailored to your requirements, meaning production times vary depending on design complexity, materials, and current demand.
✅ Supply Chain & Material Availability – Components such as glass, profiles, and hardware rely on suppliers, and availability can change daily.
✅ Technical Survey & Order Approval – Before production can begin, a technical survey must be carried out to confirm measurements and specifications. Any adjustments at this stage can impact timelines.
✅ Installation Scheduling – Our fitting teams operate on a full schedule, meaning last-minute availability is rare. The sooner we can confirm your order, the sooner we can secure your installation date.
We understand that customers want certainty regarding their order, and we always aim to provide the most accurate estimates. However, lead times are influenced by multiple factors outside our control. That said, it is in our best interest to install your windows and doors as efficiently as possible—once the work is complete and you’re happy, we can finalise your balance, and the project is successfully delivered.
First Fix Lead Times: Plan Ahead for a Smooth Project
If you’re working on a new build or renovation, don’t leave your windows and doors until the last stage of the project—this is a common mistake that can lead to delays.
One of the most frequent requests we receive is:
👉 “Windows and doors needed in 6 weeks.”
While we always do our best to accommodate customers, high-quality, made-to-order windows and doors require careful planning. Builders, developers, and DIYers should allow ample time for design, approval, manufacturing, and installation.
How to Speed Up the Process and Avoid Delays
🚀 Request a Window Schedule from Your Architect – This allows our design team to provide accurate pricing quickly, reducing the need for multiple revisions.
📐 Send Us Your Plans Early – The earlier we review your project, the more time we have to discuss finer details such as trickle vents, cill sizes, and U-values.
🏡 Visit Our Showroom – See, touch, and operate our products in person. Our team can answer your questions and help finalise specifications on the spot, reducing unnecessary back-and-forth.
📅 Don’t Assume Windows and Doors Can Be Ordered Last Minute – Lead times fluctuate daily, so planning ahead is the best way to keep your project on schedule.
What About the Competitor Who Can Deliver Faster?
Every now and then, customers tell us:
👉 “The company down the road said they can install in 6 to 8 weeks.”
We respect all businesses in our industry—delivering high-quality windows and doors is not easy, and if a competitor can genuinely provide a bespoke service within that time-frame while maintaining quality and reliability, we applaud them.
However, we also know that careful planning and attention to detail go into every successful project. We take the time to ensure every installation is right because we stand by our 10-year workmanship guarantee. That commitment to quality is why we’ve been trusted in Cornwall for nearly 39 years and why our customers return to us time and time again.
