About Us

Knebworth, Hertfordshire covering Herts, Beds and Bucks

MDM Blinds are an independent, family business with over 15 years’ hands-on experience. We’ve seen it all – and get around 99% of all known problems. We commit to advising you of any potential feasibility issues rather than just “taking the sale”; we always let you decide what’s best for you.

We have a showroom based in Knebworth, Hertfordshire and cover Herts, Beds and Bucks geographical area.

If you’ve found us, you’ll no doubt have looked for blinds in and around the Hertfordshire area and will have seen there are several companies looking for your valued business. Not surprising; these are hard times. The consumer has benefitted from cheaper pricing but possibly this has been brought about through lower-quality products being offered.

Before you buy, it’s a good idea to stick with a reliable, established company. Find one with a showroom, where you can see and feel the products offered and know that they’re happy for you to find them.

The company you choose should offer you no- obligation quotes. This way, you can compare a couple of companies. It’s a good idea to make your choice not only based on price– often there won’t be much in the price – but there will be a difference to be found in the service. We would always recommend choosing a company long-established in the area. If they can show examples of work they’ve done in the area, so much the better. It’s also a good idea to choose an independent company not tied to any one supplier – this means they can offer a more extensive choice of blinds, awnings and shutters than companies that offer only their own product range.


We cover both the domestic and commercial sectors. Our commercial portfolio includes: MBDA, Glaxo, Vauxhall, Conamar, County Councils and various high street restaurants, shops, local GP surgeries, schools, churches, shops, and estate/lettings agencies.


Pricing is fully inclusive of professional measuring, fitting and VAT (at prevailing rate).


We will bring our comprehensive range of sample books and measure your windows all free of charge, with no obligation to place an order.

PROMPT ORDER and DELIVERY LEAD TIMES (excluding bank and public holidays)

If you place an order with us, we will place your order with our network of suppliers the same day. We aim to supply and install within 10 working days of placing your order. Shutters are subject to a longer, 10/12 week lead time.

Looking For Shutters?

We understand that not every window can be dressed with a blind. Our shutter range is available via our associate company: The Hertfordshire Shutter Company
