About Us

Who We Are

We are a family-run double glazing & aluminium company based in the heart of Lincoln, with more than 40 years combined experience.

We were sick of the bad reputation the double glazing industry had - ripping people off, pushy sales and cowboy builder-type firms. We set up DS Windows & Doors to change that, and judging from our 100+ 5-star customer reviews, we are doing just that..

Our Services Include...

We supply and fit windows, doors, bifolds, shopfronts and commercial doors, and we're the home improvement company you can trust.​

Darren Stiff, Owner:

I've been fitting windows & doors in and around Lincoln since I was just 18 years old - some 20 years ago now! 

After working for a number of different companies in Lincoln I saw there was an opportunity to provide a different service.

Pushy salesmen and shoddy cowboy builder type firms give home improvement companies a bad name - which is what I set out to change when I set up DS Windows & Doors almost 8 years ago.

My experienced installers take pride in every job - no matter how big or small - and love nothing more than seeing the look on my customer's face when they're delighted with their new windows and doors. 


My promise to my customers is this:

  1. I will never pressure you into making a decision - I understand that replacing your windows & doors is a big decision, so I'll never be that pushy salesman
  2. I'll give you open & honest advice - I won't encourage you towards the most expensive option, I'll advise you based on what I think will suit your property & your budget
  3. My team and I will take care of your home as if it were our own - that means spending time laying down dustsheets, hoovering up after the job is done and spending time cleaning your new windows for you so you get the real 'wow' factor

If you're ready to discuss your new windows & doors my team and I would love to hear from you - please call us on 01522 305383 or email info@dsaluminium.co.uk
