Professional vs DIY uPVC Installation

Tempted to fit uPVC windows yourself? Here's an honest look at professional vs DIY installation.

What our installation includes

Look for this

  • Professional: correct seating true and level
  • Professional: proper sealing against weather
  • Professional: hardware set and tested
  • Professional: accountability if anything's off
  • DIY risks: leaks, drafts, stiff operation, voided assurances

One team, start to finish

uPVC windows are made to fine tolerances, and their performance depends on being seated true and sealed properly — which is hard to get right without the tools and experience. A poorly fitted window undoes the quality of a good one.

Questions

Frequently asked

Should I install uPVC windows myself?

It's not advisable — performance depends on seating true and sealing properly, which is hard without the tools and experience. Poor fitting undoes a good window.

What can go wrong with DIY installation?

Leaks, drafts, stiff operation, and poor sealing — plus you lose the accountability a professional fit provides.

Why use professional fitters?

For correct seating, proper sealing, tested hardware, and accountability if anything needs adjusting.
