At Crowne Doors & Upgrades, we have been supplying and installing premium composite, French, sliding patio, and aluminium bifold doors for homeowners across Hampshire and the surrounding counties since the 1990s.
What started as a small, local endeavor has grown into one of the region's most trusted independent door specialists. Our reputation has not been built on aggressive sales tactics or gimmicky advertising, but on a simple, honest philosophy: delivering exceptional results and treating every customer's home as if it were our own.
We understand that upgrading your home's doors is a significant investment. That's why we focus on absolute transparency, expert workmanship, and a truly personal service. When you choose Crowne, you are dealing directly with a small team that cares about the details.
We believe in doing business the right way. Here are the core pillars that have earned us recommendations from hundreds of local homeowners.
You deal with the exact same people from your first inquiry to the final sign-off. No call centres, no sales representatives, and no disconnect.
We offer free, honest home surveys and transparent, written quotes with absolutely no obligation. We let the quality of our work do the selling.
Competitive and completely transparent pricing with no hidden fees or surprise extras. What we quote is precisely what you pay.
We source only from leading, trusted UK manufacturers — including Rehau, Veka, Liniar, Doorstop, Smart, and Korniche.
Our doors are designed to exceed modern thermal efficiency requirements, helping lower heat loss and reduce your energy bills.
All our door profiles and installations come with a full 10-year company-backed warranty, giving you absolute peace of mind.
We hold ourselves to the highest standards of safety, quality, and consumer protection. Our official registrations ensure that your home improvements comply with building laws.
All our door fittings comply fully with building regulation standards. Through our Certass registration (Member No. 17-1015), we verify the quality and compliance of our workmanship, self-certify the installation, and notify the local authority on your behalf.
As a proud PWF member (Registration No. CR 4234), we offer robust consumer protections. Our customers benefit from industry-leading deposit protection schemes and insurance-backed warranties that safeguard your investment.
Unlike large national firms that subcontract installation work to third-party builders, Crowne Doors relies on our own dedicated, experienced fitters. We believe the quality of the installation is just as important as the quality of the door itself.
Our lead installers have decades of experience fitting premium residential doors. They take immense pride in their craftsmanship, ensuring that every door frame is sealed tightly, aligns flawlessly, and operates smoothly.
From preparing the threshold and aligning multi-point lock systems to finishing trims and cleaning up, this meticulous workmanship is what sets Crowne apart. It is this attention to detail that has earned us an outstanding reputation and ongoing word-of-mouth recommendations throughout Hampshire.
Based in Hampshire, we cover a wide local radius. Our team regularly travels to fit entrance doors, bifold, and patio systems in towns and villages across the southern counties.
