Brand New Personnel Door, made opening in brick work, repaired existing damaged bricks and fitted new door. Great work by Scott, Seb and Charlotte. A job well done and thank you very much, highly recommend. Second time I have used SDM over the past 10 years.


Scott was a pleasure to deal with and did a fantastic job on our new front door. Charlotte kept us updated at all times. I would highly recommend this company.


Excellent service. Pleasant and efficient. Tidied everything on completion. Did a couple of extra jobs at no charge. Very impressed!


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!


SDM Doors did a fantastic job in replacing my garage door and I can wholeheartedly recommend them. Scott was friendly, polite and knowledgeable, and his workmanship was of the highest standard. After some early indecision on my part Scott was happy to submit a revised quote and, wisely as it turned out! Come back for a second survey. The price for the door replacement was very competitive and the work was carried out promptly and with great attention to detail.
