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

Perfect! The team at DS Windows were friendly, knowledgeable and efficient from start to finish (and patient). Our renovation has gone a lot more smoothly dealing with this company. They understood what my wife and I wanted and fitted around our plans and we are so pleased with the result. Highly recommend 👌

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.

Very happy with my new front door! The process overall was extremeley good. I had lots of chats back and forth to help me decide on a colour and style, and staff were so knowledgeable and helpful and made me mockups and quotes to help me choose. Installation went very smoothly, Rob super professional and kept everything neat and tidy whilst it was being done and explained lots about after care. Very communicative about dates and prices so everything was dealt with smoothly. Very happy with my beautiful front door Thanks!!

This company was recommended to us. There is no "making good" once the job was completed. It's a all-in job. We are very happy with the way we were dealt with by the office staff and the installers were also very polite and professional. Highly recommended!

We’re really pleased to hear you were happy with both our office team and installers – we’ll be sure to pass your feedback on to them. It’s great to know the whole process met your expectations from start to finish. If you ever need anything in the future, we’re always here to help!

DS Doors and Windows came recommended to us, I cannot say how highly I would recommend this company to anyone looking to replace their existing doors and windows. From beginning to end, the communication, the guys that fitted our doors, all were absolutely amazing, we are thrilled with our new doors, they are all friendly, professional, clean up after themselves and did a fantastic job. It’s difficult these days for some company’s to deliver on what they promise but they did that and more. Thank you to all of you for everything, you are all a credit to the company
Response from the owner:Thank you so much for such a fantastic review! We’re absolutely delighted to hear how happy you are with your new doors and the service you received from start to finish.

    DS Windows and Doors exceeded all expectations. I spent quite a while searching for a company I felt I could trust. Their other reviews were really good so I decided to give them a call. I spoke to a lovely lady called Donna, she answered all my questions and was so bubbly and set my mind at ease to give them a try. Darren came to give a quote. He was very helpful and had lots of good suggestions for windows we may not of thought of. We found the cost resonable and went ahead with the order.
    I was apprehensive, expecting there to be quite a bit of mess, but need not of worried. Two lovely guys Matt and Rob came to do the installation and they were brilliant. Their work was so neat and tidy, no mess apart from a bit of dust. Could not of asked for nicer people, or a better job. Really thrilled with everything. I totally recommend this company.
    Response from the owner:Thank you so much for your lovely review! We’re really pleased you chose us and that Donna, Darren, Matt and Rob all looked after you so well. It’s great to hear you were happy with the advice, the installation, and how tidy everything was left. We really appreciate your recommendation – thanks again for trusting DS Windows & Doors!

    Had a new composite front door installed today by Matt. Matt was very friendly and polite, cleaned up after himself and made sure i was happy before he left. The customer experience from beginning to end has been great. No pushy sales team just years of experience on the job and all questioned answered and explained. You can tell this is a family run business and not a nationwide company that do a job and leave, they are people at the end of the day and interact like people. Its been a pleasure doing business with the team. Thanks everyone!
    Response from the owner:Thank you so much for your fantastic review! We’re really pleased you’re happy with your new composite door and the service from start to finish.
