Window Handover Documentation: What You Receive at Project Close

t404-38

Window handover documentation is the set of papers that closes out an aluminum window project: the final drawing, the written specification, the installation record and warranty registration, plus a care guide. Keep these together with your building file, since they prove what was supplied and help with any future service or resale.

Why handover documentation matters

When a window project is finished, the physical work is only half the job. The paperwork tells you exactly what was made, where it was installed, and under what conditions it is covered. Without it, questions about glass type, frame colour or fixing method are hard to answer years later.

Good documentation also protects you if a building committee, architect or buyer asks for proof of specification. Ask for everything in writing before the final payment step, and store a digital copy alongside the paper originals.

The documents you should receive

A complete handover pack usually includes the following items. Check each one against what was agreed in your approved specification.

Final as-built drawing showing each window's position and size
Written specification covering profile system, glazing, hardware and finish
Installation record with the date and the fixing method used
Warranty registration form signed by both sides
Care and maintenance guide for the frames, seals and hardware

If any item is missing, request it before the crew leaves the site.

Warranty registration step by step

Warranty registration links your project to the factory's records, so the right people can respond quickly if a problem appears. Fill in the form with accurate addresses, unit numbers and the installation date. Mistakes in these details can slow down a future claim.

Keep a copy of the signed form and note the reference number in your phone or property file. The exact coverage terms are set out in the document itself, so read them rather than relying on memory of the sales conversation.

A simple care guide for aluminum windows

Aluminum windows need very little care, but a short routine keeps them working smoothly for years. Clean frames and tracks with mild soapy water and a soft cloth, then rinse and dry them. Avoid abrasive pads and strong solvents that can dull the finish.

Clean tracks and drainage slots every few months to remove grit
Lubricate moving hardware lightly as the care guide describes
Check seals for cracks or gaps once a year
Report any sticking or water ingress early

What to check at the final walkthrough

Before signing off, walk through each window with the installer. Open and close every sash, test the locks, and look for scratches, dents or uneven gaps around the frame. Compare the frame colour and finish with the approved sample under daylight, since indoor light can be misleading.

Confirm that sealing and cleaning of the surrounding wall are complete. Note any snag on a simple list and agree on who fixes it and when. Sign the handover only once the list is closed or clearly agreed.

Filing and keeping your documents

Create one folder, paper or digital, labelled with the project address and date. Place the drawing, specification, installation record, warranty form and care guide inside. Scan everything and save the copies in a cloud folder you can access from your phone.

If you sell the property or join a building committee later, this folder becomes valuable evidence of what was installed. A few minutes of organising now saves hours of searching later.

Frequently asked questions

Who keeps the original warranty form?

The homeowner or building committee should keep the signed original, and the factory keeps its own copy. Store a scan in your digital property folder as well.

What if I lose the handover pack?

Contact the factory with your project address and installation date, and ask for a copy of the drawing, specification and warranty record. Records are kept on file for reference.

Do I need to register the warranty myself?

Yes, the registration form should be completed and signed at handover so the project is properly recorded. Check that your details are correct before you sign.

How often should I follow the care guide?

Basic cleaning of tracks and frames is best done every few months, with a yearly check of seals and hardware. Following the guide keeps the warranty conditions clear and the windows running well.

Common mistakes to avoid

Signing the handover before reading the specification or checking the walkthrough list is the most common error. Losing the documents in a drawer or email thread also makes later claims much harder.

Our recommendation

Photograph each window and the signed documents on the day of handover and save them to your cloud folder. Ask for the reference number in writing so any future call can be matched to your project immediately.

Summary

Window handover documentation covers the drawing, specification, installation record, warranty registration and care guide. Check each item at the walkthrough, sign only when the snag list is closed, and store everything in one folder.
