With an excellent reputation for service and quality, SDM Doors are your number one choice for bi-fold doors in Harpenden. Based in the local area, we offer a wide range of  products throughout Harpenden, with a strong focus on repair and installation services. We pride ourselves on always putting our customers first, and our team strives to maintain a close relationship with each and every one of our clients.

Recently, more and more homes are adding bi-fold doors as a feature due to their security, style and the way they open and close seamlessly.  They can allow for more space and often look as impressive from the inside as they do from the outside. Of course, materials and installation are paramount to getting the most out of any bi-fold door, and that’s where we come in.

As a family business, we place a high value on quality. Your home is an important space and our goal is to help you make the most of it. We employ some of the best fitters in the country who will carry out the perfect installation of your chosen door, and our team will always be there should you encounter any issues in the future.  We don’t believe in hard selling and don’t employ a large sales team; instead, you’ll get to speak to a designated member of a team whenever you contact us so you always know where things stand.
