Customer Reviews

Scott and his team arrived on time and were clean and tidy throughout their works on our house. They did a wonderful job and their attention to detail was flawless. I would highly recommend

Lovely new front doorHertfordshire

Truly delighted with the service. Scott promised me the moon when he gave us a quotation and delivered more! Everyone who visits us comments on how beautiful the door looks! Charlotte kept us posted on the manufacturing lead-time and estimated delivery date. On the scheduled day, Scott and his assistant Sebastian arrived on time, worked tirelessly and finished the job ahead of the estimated time. They even fixed the outdoor lights for me. The job was done with utmost cleanliness and perfection. No room to find any fault. Thank you SDM Doors! May your business flourish!

Replacement Front DoorNorth London

I found this company via Check a trade. From when I rang to arrange a measurement and being given a quote with a visual mock up of the door I had chosen was within a couple of days. All correspondence was via email, Charlotte was quick to answer my emails and any queries I had. On the actual door fitting day itself, the knocker I had chosen had not arrived, I think there may have been a mix up with Charlotte being on holiday that week. However, on return Charlotte quickly resolved and even give me a £50 discount as a kind gesture of the mix up. Excellent company would highly recommend
