Our surveys

Whether it's a single back door or a whole house of windows, every job gets the same careful approach.

  • Measure for manufacture

    Every opening measured accurately and frame sizes worked out, so windows and doors are made to fit first time.

  • Pre-installation checks

    The lintel above, the cill below and the brickwork around each opening checked, along with access, before anything is ordered.

  • Building Regulations flagged

    Fire escape windows, safety glass, ventilation and energy-efficiency requirements spotted at survey stage.

  • Clear survey reports

    Sizes, notes and photos for every opening, sent to you promptly and easy to order from.

  • Doors, bi-folds and sliders

    Front and back doors, French doors, bi-folds and sliding patio doors surveyed with the same care.

  • Check surveys

    Already measured? We'll check the sizes and details on site before you commit to manufacture.

What you get back

Each opening gets its own reference, size and notes, with photos to match. This is how a three-opening job might be recorded.

Questions

What is a fenestration survey?

Fenestration means the windows and doors in a building. A fenestration survey records the exact size of every opening, along with anything that affects the new installation, such as the cill, lintel, access and Building Regulations requirements. That way, products can be made and fitted correctly.

How much does a survey cost?

It depends on the size of the job and how many windows and doors need surveying. Send us the details and Grant will give you a price before anything is booked.

How soon can you come out?

Tell us your timescale when you get in touch and Grant will offer the earliest slot that works for you.

What do I get after the survey?

A clear record of every opening, with sizes, notes and photos, ready to order from. See the example survey sheet.

Can I send photos first?

Yes, and it helps. Photos of the windows and doors let Grant plan the visit. Send them by WhatsApp or email.

Which areas do you cover?

We're based in Essex and cover the surrounding areas. Send us the job postcode and we'll confirm.

Do you work with trade customers and homeowners?

Yes. We survey for window and door installers, builders and contractors, and for homeowners. Whether you need a one-off survey or regular cover, get in touch.
