Ordering online is the best and most effective way to getting the service you want when it most suits you, your time, your day. When you buy a Titan door, not only are you getting the state of the art in burglary prevention, but the door also serves as a fire-door. At ASL we are dedicated to producing the finest, strongest and most beautiful security steel doors available.
MODELS All of our luxury Titan Steel Doors are bespoke therefore we can supply any size, colour and design of your choice. A security door is connected with yards of wire that helps sense weaker spots and also measures the temperature of the fire. Manufactured to meet all the demands of thermal and sound insulation, this can be an ideal high security door to be installed in domestic spaces.

ASL has been absolutely helpful from the moment I urgently contacted them after being accidentally locked out due to the malfunctioning lock. They have immediately arranged a locksmith who arrived within 20 minutes, unlocked in 30 seconds, and repaired it giving detailed explanations. I was amazed by their professionalism and will definitely call them again in case of emergency or in need of replacing the locks or doors.

Had my steel door installed from ASL yesterday, and after much delay due to covid i'm very pleased with it. I’ve just moved into an apartment and wanted a door that was more secure, fire rated and would allow me to retain the existing appearance on the outside of the door whilst matching my new internal doors as part of my refurbishment. ASL came out very quickly to do the survey and were very helpful in getting exactly what i wanted in terms of matching to the existing door on both the outside and my internal doors inside.
This door is expensive! there’s no getting away from that. However

Horrible experience. Will definitely NOT RECOMMEND to anyone. We got in touch with Steel Security Doors 5 weeks ago to Book a Survey thinking they'd be a professional company that is able to deliver the requested service efficiently. We read the reviews and thought they were trustworthy but unfortunately, they kept moving the appointment of the survey (a day before we had booked the survey, meaning we had already requested our days off of work for this) and now 5 weeks have passed and still this survey hasn't taken place. We have had to call them up several times and chased them through emails

Henry was a great carpenter. Came to change my door and locks. Very meticulous and stayed until the job was done. Good quality door.

Very hardworking and trustworthy firm. Ian and his assistant worked tirelessly all day to fit our new door and delivered an excellent result. Ian was clearly very knowledgeable and gave very helpful suggestions on how to improve the security of our building. I tried repeatedly to offer refreshments but they always refused, they were really polite and did their best to cause the least disruption. When they finally finished (it was dark already!) they were going to tidy up but I thought I'd spare them the final task! Very happy and would recommend wholeheartedly.

ASL offer help at all times, they are very communicative and friendly. Very quick at responding to emails and calls. Quick delivery time & easy to order keys through their website. I highly recommend using ASL London Locksmiths as they are reliable in each and every way.
