Lincoln's top reviewed, family-run double glazing company

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 200+ 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.​

Double Glazing Lincoln

Darren Stiff, Owner:

I’ve been fitting windows & doors in and around Lincoln since I was just 18 years old – some 22 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 10 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

I love my new door!! Professional service throughout and very accommodating when I changed my mind on design. Thank you! ⭐️⭐️⭐️⭐️⭐️
Good product very neat and hassle free fitting had two new windows upstairs bedroom and bay window in front room all done in one day very neat and tidy job would definitely recommend
Excellent job professionally executed. The job was a simple replacement of some blown double glazing units but from the initial measuring to final fitting, the service from DS Windows & Doors was exceptional. No hard sell from the sales rep, and the fitter, Rob was excellent, friendly and very professional. I would not hesitate to recommend DS Windows & Doors and they will be my first call for any future window or door needs.
Brilliant service and great job thank you
Phenomenal service throughout. Jim was very informative about our options and was very helpful. Rob came and put our new front door in and did an excellent job. He was friendly and polite. We are extremely happy and would highly recommend. Will definitely use again in the future!

    An overwhelmingly positive experience. Replaced my door with a better quality composite one. Effortless (from my point of view), quick, accurate measurements and quote, installed it in one morning and it looks fantastic (not to mention being much more secure). The installers were friendly and polite, did a high quality job and cleaned up after themselves- couldn’t ask for more.
    Simple quote process, they came when they said they would and did what they promised and the end result is a big improvement on the old windows. No more condensation on the insides!

    From the moment I made the enquiry to the day I had my new composite door installed, DS Doors were nothing but brilliant. The back office team along with Darren and Matt who fitted my front door were amazing and made sure there was no mess after installation. The door looks amazing and I’m sure and know that others will follow suit in replacing there existing front doors to these new amazing looking front doors. Thank you DS Doors for making our home look even better than before👍🥇

    We had an issue with our bifold doors where they were not sealing shut and catching on the bottom. We contacted DS windows and they quickly arranged someone to come out and have a look. The gentleman who came was very friendly and did an excellent job in sorting the issue. I would definitely recommend DS windows for their quick, professional and friendly service! We would certainly use them again!
