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

The team have been great from quote through to install. Great communication, fantastic quality, great work all round – efficient and clean. We couldn't be happier with the new doors and glazing units. Would definitely recommend Darren and his team.

We have just recently had an installation of all new double glazing and a beautiful bi-folding door supplied and fitted by DS Windows of Lincoln. The process was seamless, the customer care exemplary and the fitting was excellent. Special thanks to Donna for excellent and proactive contact, care and advice. DS Windows are a first class operation

We're so pleased with our new windows from DS Windows and Doors. The windows themselves are gorgeous and finished to a really high standard, and the professional installation by Matt and Rob was far smoother than anticipated - efficient, tidy and painless. On top of this, the customer service was fantastic - Donna was so organised, helpful and attentive, making the whole process effortless from start to finish. We’d recommend DS Windows and Doors to anyone and would definitely return to them in the future 😊

Absolutely can’t fault this company. Extremely helpful and accommodating. 8 weeks from first enquiring to fitting. Darren, Donna and Mark were second to none in their customer care and attention to detail. Will definitely use again.

    I am very happy with the overall service DS Windows and Doors provided. Donna was very quick with her responses to my questions and sending over a quote for our new windows. The fitters were very efficient and tidy and did a fantastic job. Highly recommend and would use again.
    Steve H.
    Contacted them via phone to request a quote. Was told by the lady who answered that I would get a rough estimate in a few days. Nothing was sent, so left a voicemail and also sent a message through their website contact form, yet nobody bothered to get back to me and was ultimately ignored.
    Penny S.
    Very good service. The guys were very polite and the price was very competìtive.
    Response from the owner:Thank you for your great review! We’re really pleased you were happy with the service and found the team polite and the pricing competitive. We really appreciate your kind words – thank you for choosing DS Windows & Doors!
