ABOUT US
Prime Door Company is a locally owned door manufacturer based in Marlborough, dedicated to supplying high-quality, made-to-order prehung doors . As a newly established business, we combine fresh energy and innovation with an unwavering commitment to craftsmanship, giving trade professionals a reliable partner for every project.
Our factory is equipped with a state-of-the-art CNC machine, giving us the precision and efficiency to manufacture doors to exact specifications. From handle boring to hinge placement, every prehung door is engineered for a flawless fit and finish, reducing errors and rework on site. We source door leaves from trusted suppliers including Hume, Superior Doors, and Hallmark Doors, giving you an extensive range of styles, materials, and finishes to suit any design brief.
Being based locally means we can offer free delivery to your depot or job site, quick turnaround times even on custom orders, and hands-on support if any issues arise on site.
Save time. Reduce waste. Get a better result.
A pre-hung door arrives already fitted into its frame, hinged, and ready to install — no cutting, packing, or on-site adjustments required. For builders, joiners, and homeowners alike, that means a faster, more reliable installation from day one.
Faster Installation
Traditional site-hung doors require measuring, cutting, hanging, and adjusting on site — all of which takes time and skill to get right. Pre-hung doors remove most of that work. The door and frame arrive as one unit, so installation is largely a matter of positioning, fixing, and finishing. This can cut installation time significantly compared to hanging a door from scratch
Consistent, Reliable Quality
Because our doors are built and checked in a controlled workshop environment, you get a level of consistency that's difficult to achieve on site. Every door is squared, aligned, and quality-checked before it leaves our workshop — so what you receive is ready to perform, not just ready to look at.
Better Long-Term Performance
A door that's properly aligned in its frame from the outset is less likely to develop issues over time — such as sticking, gaps, or uneven wear. Pre-hung doors are built to sit correctly in the frame from day one, helping reduce callbacks and maintenance down the track.
Ideal for a Range of Projects
Whether it's a new build, renovation, or commercial fit-out, pre-hung doors offer a practical solution for projects where time, consistency, and quality matter. They're particularly valuable for builders managing tight schedules or multiple units where efficiency on site makes a real difference.
Less Waste, Less Mess
Site-hung doors often involve on-site trimming and adjustment, which creates waste and mess that has to be managed and cleaned up. Pre-hung doors arrive ready to fit, reducing offcuts, dust, and the extra time spent tidying up after installation.
