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

Fantastic Service from Start to Finish! We received emailed confirmations and updates throughout. The quote was set out very professionally as was all the paperwork. All the team were friendly and professional. The installer Rob was great. He turned up exactly on time both days, he was friendly, respectful, professional and he kept everything clean and tidy. Great Job by all of you. We will be having them back to do more work in a few months 🙂

So nice to have some old school style customer service from start to finish. From getting a quote to lots of emails back and forth the service was 10/10.
Regular updates and options given making the whole experience so easy and professional.

Come installation day, emails few days before highlighting the order of the day. Matt arrived on time and is such a lovely and hard working individual. Regular check ins from Matt throughout the day to make sure I was happy.

Once All complete, all cleaned down, rubbish taken away and porch brushed down followed by an explanation about the locks, key box the cleaning of the door. Even down to a little pot of touch up paint should I incur any scratches over time.

Finished job so good it makes the windows look tired so already booked in for a quote to replace 😂.

I would highly recommend DS Windows and Doors, they are a small local business, very competitive on price but customer service is first class.
Thank you all.

From start to finish this was a great company to work with. We got a quote for a new composite door very quickly and the ordering process was easy. Our door was fitted today and it’s just what we wanted. All staff have been really friendly and helpful. Highly recommend.

Matt fitted a new door for my mother and she couldn’t recommend him highly enough. The door looks fantastic and she was extremely happy with the customer service and care she received
