Buying windows online: a checklist before you order

Buying windows online without nasty surprises: what to check on the seller, the quote, delivery and fitting before you pay.

Buying windows online is safe if you check three things before paying: who the seller is and who gives the guarantee, whether the quote describes every window point by point, and what exactly the price includes. Made-to-measure windows can't be returned within 14 days, so everything needs to be clear before you order, not after delivery. Here is a list you can work through with the quote in hand, whether you order from us or anyone else.

Buying windows online: check the seller

  • Are the full company name and address on the website? Ours: PPHU GALI, ul. Księdza Drozdka 31, 42-660 Kalety, Poland.
  • Do you know who makes the windows and from which profiles? Ours come from the All Windows Group (AWG) factory, where we are an official dealer, on VEKA, Kömmerling, Salamander, Gealan and Aluprof profiles.
  • Who gives the guarantee, for how long and on what? The GALI guarantee lasts 2 years and covers profiles, hardware, sealed glass units, roller shutters and motors. It doesn't cover damage from incorrect fitting.
  • Will you get a declaration of performance and CE documents with the delivery?
  • Can you talk to a person before you pay? Contact details should be easy to find.

Check the quote line by line

  • Profile system by name, for example Kömmerling 76 MD, not just "uPVC window 76 mm".
  • Uw of the whole window, not only of the glass (Ug). What the Uw value means is explained here.
  • Glazing: double or triple, spacer, and the type of glass where you need it.
  • Colour: white, colour outside with white inside, or the same colour on both sides. One colour per order.
  • Frame sizes of every window, not the size of the opening.
  • Opening side of every sash, seen from inside.
  • Extras: roller shutter, fly screen, sill, each on its own line.

We check sizes, opening sides and descriptions on every quote before anything goes into production. We have worked with windows since 1997, and after more than 5000 orders we know that two things cause most of the trouble: the opening size given instead of the frame size, and an opening side described from outside. That's why you get a drawing and specification to approve before production. How to compare two quotes using the paperwork is covered in our article on the declaration of performance.

Check what the price includes

  • Is transport in the quote as a specific amount? We charge it per place on the rack by delivery country and state it before you order.
  • Is the price gross, and which VAT applies? For delivery to another EU country we charge the VAT of the delivery country and account for it through the OSS scheme. You see the rate and amount in the quote. This is general information, not tax advice.
  • There are no customs duties between EU countries, so you don't pay any on a delivery from Poland within the EU.
  • When do you pay, and how much? With us, the order is placed with a 100% payment before production, because every window is made to your sizes.
  • Do you know there is no 14-day right of withdrawal for made-to-measure windows? This follows from Article 16(c) of Directive 2011/83/EU and applies across the EU.

Check the delivery

  • Production time: with us 3–8 weeks from receipt of payment, with the exact date in the order confirmation.
  • Will you see the finished windows before dispatch? We send photos before loading.
  • Who unloads? The windows arrive on racks and unloading is up to you: a forklift or 2–3 people.
  • Can a lorry reach the site?
  • Where will the windows stand until fitting? Upright, under cover, away from sun and damp. Remove the protective film no later than 4 weeks after delivery.
  • Check everything in front of the driver, write any damage on the delivery note and take photos.

Sort out fitting before you order

We don't offer installation, so plan the fitting early. Book a fitter for the delivery date or plan to do it yourself. Order the fitting materials at the same time: foam, tapes, fixings and packers. The configurator suggests them in the summary. A window is fixed mechanically with frame fixings or anchors, and the foam only insulates. Details depend on the system and the wall, so follow the manufacturer's instructions.

When everything is ticked off

The easiest way is to run through the list with your own project. In the window configurator you see the price straight away, after every change, and we prepare the quote with transport within 3 working days. We recommend at least 2 windows or 1 lift and slide door. How buying direct from Poland works is explained in windows from Poland without middlemen, and all systems are listed under uPVC windows.
