Darren Stiff, Owner:

I've been fitting windows & doors in and around Lincoln since I was just 18 years old - some 16 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 Aluminium Windows & Doors almost 5 years ago.

I 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. I'll take care of your home as if it were my 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 I'd love to hear from you - please call me on 01522 305383 or email info@dsaluminium.co.uk
