Window Survey
Every window and frame on a building, photographed from directly in front of it rather than from the ground at an angle. Useful for replacement schedules, condition reports and access-free counts.

Every window and frame on a building, photographed from directly in front of it rather than from the ground at an angle. Useful for replacement schedules, condition reports and access-free counts.
What it shows
- Every opening on every elevation, counted and photographed
- Frame condition — rot, corrosion, distortion and failed paint
- Blown or failed double-glazed units where visible
- Perished, split or missing seals and mastic
- Cracked, chipped or missing glazing
- Damaged or missing trickle vents and ironmongery
- Cills, lintels and reveals, and their condition
- Escape and access openings
- Openings at high level and to rear elevations that cannot be seen from the street
Save time and money on a window programme — count and specify from square-on imagery.
Get in touchWhy ground-level counts go wrong
A window schedule built from the pavement is built from bad information. Above the first floor you are looking up at an angle, so the reveals foreshorten and the openings distort. The rear elevation may not be visible at all. Anything set back behind a parapet is invisible.
What tends to happen is that a contractor prices from a partial count, then finds more openings, different sizes or worse condition once the scaffold is up — and the variation lands on the client.
Photographing each elevation square-on, from its own level, removes most of that. You see every opening on every face at the same scale and the same angle, which is what makes a count reliable and a specification defensible.

Save Time And Money On A Window Programme
A window schedule built from the pavement is built from bad information. Above the first floor you are looking up at an angle, the reveals foreshorten, and the rear elevation is often not visible at all.
What follows is predictable. A contractor prices from a partial count, then finds more openings, different sizes or worse condition once the scaffold is up — and the variation lands on the client.
Photographing each elevation square-on removes most of that risk. A survey covers:
- Every opening on every elevation, counted
- Frame condition, rot, corrosion and distortion
- Failed seals and blown units where visible
- Cills, lintels and reveals
- Trickle vents, ironmongery and escape openings
- High-level and rear openings the street cannot see




One Specification Across A Whole Estate
The value grows with the number of properties. Twelve addresses photographed by whoever was available produce twelve different standards of information, and a schedule built from that is a schedule built on sand.
We fly a programme as a programme: the same height, the same angle, the same order at every address, delivered together and indexed by address. That means a specification can be priced from one consistent standard across the whole stock.
You can take indicative dimensions from square-on imagery, and it is usually enough to build a schedule and price a job. It is not a measured survey, and final sizes should still be checked before manufacture.

Questions
Can I measure from the photographs?
You can take indicative dimensions from imagery captured square-on, and it is usually enough to build a schedule and price a job. It is not a measured survey and should not be used for manufacture — final sizes should be checked on site.
Can you do a whole street or estate?
Yes. That is the case where this pays for itself, because every property is captured identically and the whole programme is priced from the same standard of information.
Do I need to be there?
No. We need safe access to somewhere to take off and land, and to know about anything on site we should avoid. You are welcome to be there if you would rather point things out in person.
What happens if the weather is wrong on the day?
We move it. Wind and rain make for unsafe flying and soft, unusable pictures, and a survey you cannot rely on is worse than no survey. We watch the forecast and give you as much notice as we can.
Is it legal to fly over my property?
Yes, within the rules. We hold a CAA Operational Authorisation and every flight is planned against the airspace, the surroundings and the people on and around the site before we attend. If a site needs a permission we cannot get, we tell you at enquiry rather than on the day.
Tell us about the site and we will take it from there
A site postcode and a sentence about what you need is enough to get started.
Get in touch
Provide a site postcode or boundary and a short description of the required output. We will confirm the deliverables, level of detail.
- A site postcode is sufficient to price most instructions
- Written quotation, in most cases the same working day
- Deliverables and formats agreed at instruction
