We have been in the door business for over 14 years now, but CSM Doors Ltd is a relatively new venture started in early 2017.

Do you have any customer reviews that I can read?

Absolutely, yes. We invite our customers to review us on any of their favourite platforms like Facebook, Google and Yell, but we are most easily found on TRUSTPILOT and MyBuilder at the moment.

What payment methods do you accept?

bOn the website we can accept VISA, MasterCard, American Express or Apple Pay, but you can pay by cash, cheque or bank transfer if you buy direct from our showroom.

How can I get in touch with you?

We prefer to do business personally, so ideally you could call us on 01513522092 or visit us here on the Knowsley Business Park if you’re local.

However, if you prefer the digital approach then you can email us at or chat to us on our live service during business hours.

What are your opening times?

We are open from 9am until 5pm on Monday to Friday and from 9am until 2pm on Saturday. We’re only closed on Sundays and Bank Holidays.


What kind of doors do you sell?

We sell a very wide range of internal doors including oak, white, walnut, pine grey and double doors. These can be pre-finished or unfinished and we also carry fire doors. You can see these here.

We also sell oak and hardwood external doors, both pre-finished and unfinished, which are here.

Do you also sell door accessories like handles and locks?

We do indeed, you can find a comprehensive range of handles in brass, chrome, gunmetal, nickel and more. We also carry turn and release locks in the same materials to match. All of these can be found in our Accessories section.

Can you fit doors? How much does it cost?

Fitting doors is our real speciality, because we use proprietary laser technology and a computerised cutting machine to measure, cut and install doors.

You can read more about what makes this so unique here, but the best thing about it is that it’s probably cheaper than your local joiner would be (the average cost per door is £39 + VAT).

Do you offer a door finishing service? How much is it?

Yes, we also offer spray finishes of a superb standard and you can select the colour, shade and lacquer you want. This service typically costs between £25 and £45 +VAT depending on the type of door involved.

Do you have a showroom? Where is it?

Our showroom is at Unit 53, North Mersey Business Centre, Woodward Road, Knowsley Industrial Park, Liverpool, L33 7UY. You can get directions to it here and we’re open 9am-5pm on weekdays and 9am-2pm on Saturdays.

What areas do you cover with your digital door fitting service?

We'll go anywhere in England, Scotland, or Wales if the job's big enough, but we mostly fit doors in Birkenhead, Liverpool, St. Helens, and their surrounding areas.


Do you have a price promise?

You bet we do, we pride ourselves on offering the best prices of all of our competitors.

So, if you find the same door for a cheaper price in stock and available for immediate delivery anywhere else then just let us know on 01513522092, at or on our live chat service and we’ll beat it!

Do you offer free delivery?

Yes, you can get free delivery on all orders over £500.


What’s the difference between a pre-finished and unfinished door?

A pre-finished door is a cost-effective, hassle-free and superior alternative to an unfinished door. While unfinished doors are pre-sanded they are otherwise untreated and it’s left up to you or your joiner to stain, varnish or paint them.

Alternatively, pre-finished doors are sprayed in the factory and come to you ready for fitting and showing off to your friends and family.
