More About Us

Who we are

Threefold Windows & Doors is a small team of time served fenestration experts, dedicated to designing, supplying and installing the perfect windows and doors for your project.

Whether you have a period style property or a modern new build, we have a range of windows and doors to suit your home improvement project. We work on projects big and small from residential repairs and replacements to full house renovations and commercial properties.

Why choose us

Breaking the tarnished reputation of the ‘double glazing sales company’ is our focus; we don’t price in your home and refuse to leave until you sign, nor do we offer outrageous and unbelievable short-term discounts to scare you in to buying sooner. Our process is a pressure free home visit or a consultation over email to establish your likes, dislikes and requirements for your new windows and doors before providing a detailed no obligation quotation by email for you to review.

Nothing makes us happier than hearing feedback like the below comments from some of our customers.

I never thought I could be excited about double glazing, but I can’t wait to have my new windows installed.

The new windows have made our house look brighter and even, somehow, bigger.
