Why a site visit matters on mixed glazing projects
Lanterns measured properly
Overhead glazing needs accurate opening checks so the blind can span it cleanly.
UPVC compatibility checked
Frame details are assessed before we recommend a Perfect Fit system for the window.
Recesses and slats considered
Venetian blinds are measured around depth, handles and day-to-day use of the opening.
Different windows need different measuring methods
Different windows need different measuring methods, and that becomes obvious quickly on projects in Bromley. A roof lantern blind has to span elevated glazing cleanly, a Perfect Fit blind depends on the UPVC frame being compatible, and a venetian blind needs room for the slats, controls and recess. That is why we work through home visits rather than a showroom guess. When we visit a property in Bromley, we can see the glazing in context, judge how the light behaves and check the practical details that decide which system will actually work well day to day.


The visit settles the details you cannot judge from photos
That survey stage helps us settle the things you cannot confirm from a brochure photo. We measure the lantern opening, assess bead depth and handle clearance on UPVC frames, and check recess depth and opening movement on more conventional windows. We also talk through privacy, glare and how often each blind will be adjusted. Once the right route is clear, we return to Bromley to fit the chosen product so the operation matches the window instead of fighting it.
Frequently asked questions
Why do roof lantern blinds in Bromley need an on-site measure?
Because the blind has to work across elevated glazing, not just cover a flat opening. At your Bromley property, we measure the lantern carefully, assess reach and look at how the light behaves in the room. That gives us the detail needed for a practical blind, not a hopeful estimate.
How do you know if Perfect Fit blinds will suit my Bromley windows?
We check the actual UPVC frames during the survey. Bead depth, handle clearance and the frame layout all matter. Those details tell us whether Perfect Fit is suitable or whether another made-to-measure blind will work more cleanly on that particular Bromley window.
Can I compare venetian blinds with other options during the visit?
Yes. The survey is the right time to compare how venetian blinds would sit in the recess against other routes for the room. We can talk through slat control, light levels, privacy and how the window opens so you choose a system that fits the way the space is actually used.
