Hydraulic door closers have a similar design in that they all have a spring which causes the door to close and they all have a piston with a hydraulic seal which moves along the cylinder.

At the top of the cylinder is located a valve which can be opened and closed. This valve allows the hydraulic fluid to escape into the hydraulic reservoir as the spring pushes the piston along the cylinder.

If the valve is closed off the hydraulic fluid is pushed slowly into the reservoir, and so the door closes slowly.

As the valve is opened the fluid is pushed into the reservoir faster and more easily, and so the door closes quickly.

By adjusting these valves on the door closer, we can adjust the rate at which the door closes to our satisfaction.

Door closer valve adjustments

However, in practice, most door closers have two or more valve adjustments.

One valve is so that the closing speed of the door can be adjusted while the other valve adjustment is so that the latching speed can be adjusted.

The closing speed of the door closer is generally between 100 degrees and 20 degrees while the latching speed is between 20 degrees and 0 degrees.

In addition to these valve adjustments, door closers have other similar operational adjustments which are often mistaken for valve adjustments and when used by inexperienced technicians often result in dire consequences for your door.

In short, it is always better to use a trained technician when adjusting a door closer.

Various types of door closers

There are different types of door closers.

Some door closers are visible on the door or the door frame, and some are not easily seen since they are located on the floor or the door frame.

As to those that are visible on the door or frame they are referred to as, Surface Mounted Door Closers.

While those which are not visible and are located in the door frame above the door are referred to as Transom Door Closers.

Those which are located on the floor are referred to as, Floor Springs.

Surface mounted door closers

Surface mounted door closers, if installed on the inside of an inward opening door, have their arms projecting out at right angles to the face of the door.

Surface mounted ones installed on the inside of an outward opening door have their arms running parallel to the face of the door.

Improper installation can lead to problems you want to avoid

This difference in installation is very important for the correct operation of the door closer.

Also, the door closer must be positioned at the stipulated height relative to the door frame, and it must be within the specified distance from the door jamb.

The positioning of the door closer on the door compared to the door jamb is determined by the manufacturer such that the door closer is most efficient in operation and delivers maximum life.

Note that with hidden door closers there are no hinges on the door and door jamb.

In the case of a floor spring, we have a pivot at the top of the door going into the transom door jamb, while with a Transom Door Closer we have a pivot bearing on the floor.

Identifying transom door closers

You can identify a transom closer quite quickly by looking at the top inside of the door. Look for a little plate about 40mm x 15mm, which held onto the door with two small screws.

Usually a Philips head, or if the plate is absent, you will see two or three Alan screws. If the small plate is present for this door closer, it may display a brand name.

The floor spring door closer can be identified by another plate, which is found on the step underneath the door.

And the size of that plate can vary, from being 75-100mm wide and 200-300 mm long, and it is usually shiny stainless steel possibly with a brand name of the door closer showing. This metal plate is screwed to the floor spring with about four countersunk screws.

Don’t waste your time and money

Different brands and different models of door closers deliver very different performance. Also, some door closers have stay open features.

It is always best to choose the door closer which is best suited for the job at hand because, the installation of the incorrect one nearly always, results in a waste of time and money.

From the first enquiry phone call to my waving the Adsafe team off after completion of the job I felt confident and happy that I’d chosen the right company to fix my ageing door. Stephen and Jess did a wonderful job, and I’m happy I can use the door with just one finger. Thank you!!

From the first over phone discussion to the job completion Steve and Jess did a fantastic job. Our 50 year old difficult to open sliding door operates now better than a new door. I would recommended Adsafe Doors to repair your sliding doors.

Stephen and Jessie performed a miracle here. A heavy sliding glass door which had dropped so low it scraped along the floor causing an ear-piercing screech. Now it glides silently along its track at the touch of one finger! Professional duo with a lovely friendly rapport, I can't recommend these two highly enough. Thank you both so much, I feel extremely lucky to have found you.

Contacted this company originally via their online site - they did not respond. I called them a week or so later - spoke to Stephen. He gave me a quote over the phone - no issues and we discussed what may or may not need to be done. He called me on a Sunday - confirmed possible works - gave him an address - we booked job in. Job was planned for tomorrow ( Nov 2023). Stephen called me just now - " sorry - my guys dont want to travel that far to your suburb" - we cannot do the job now for that reason. I'm an hour from North Parramatta - their company address. So this comany - good or bad - cannot respond to their own website traffic without a prompt - then after confirming the job - cancel the day before - because an hour is too far to travel. We live in Sydney - everywhere is an hour. I'll let you draw your own conclusion. I wish I could give no stars. 2/2 - I can get to Parramatta most times in an hour - its a pain - but its do able. Google maps says to your address to mine 1hr 8min. My review is accurate and you called me & accepted the work. Dont accept the work if you cannot do it or dont want to travel to do it. Its no prob anyway - I replaced the rollers myself for less than $50 - and the doors work fine again.

Had sliding door runners that had self destructed due to sandy backyard. Door was extremely difficult to move. Contacted Stephen to describe the problem out at Kingsford. Quote and convenient date and time organised. Stephen rang that morning, was running a little early, no problem. Had enough time to secure my 2 dogs. Requested him when accessing our property to semi secure the side gate so our dogs couldn't escape. Stephen explained the process, replaced the original poor quality minimal door runners, with what looked like heavy duty multiple runners. Door is now opening and closing with minimal effort. Cleaned up worksite, including vacuuming the aluminium shards off the ground, from adapting and correcting the door running guide. Really happy with Stephen's and helper pleasant demeanour. Very happy to recommend. Allan

We had a very hard to close sliding door that had been in situ for 12 years. It took a huge heave to open the door and we thought would have to replace the entire door and track. We called Steve and within a few days he came out to fix our door. Once Steve had finished we could open the sliding door with our little finger - the result was truly remarkable! We couldn't recommend the Adsafe Doors service highly enough.Thanks Steve !

Steven and partner came today and fixed a glass sliding door that had become difficult to open. Explained what they would need to do, and put in double rollers as opposed to the single rollers already in the door. Laid a new track - door opens without effort now - perfect. And Steven kindly fixed the noise issue with the crimsafe door as well.

Needed both hands to open & close our 30 year old doors, the glass & flyscreen sliding doors we very hard to operate. After comparing costs for replacing doors and frame or calling in the repair experts decided to go with the experts in Steve. Called and told him the problem, Steve gave a quote over the phone and arranged to attended site in a few days. Steve and his apprentice worked their magic in under 2 hours, I fair dinkum cannot believe the difference they have done. Boths doors can be slid the whole lenght of opening by one finger, it's even better than when the door was brand new. You will not be disappointed with this company and would highly recommend.

Contacted Adsafe Doors to repair sliding glass door. Was quoted $800 over the phone. I asked a few questions about the price, how long does it take and cost of parts. He refused stated that it was a phone quote and he does not supply that information. He then was very rude when I questioned why he could not supply an invoice stating the labour and parts cost. I said any repair work, you are usually given a cost for labour and parts. He denied that this ever happens, continued to be rude. He could not guarantee that the door would be fixed, he would not come out and look at the door for a service fee. Something I was willing to pay. He continued to be rude. I have since had my door repaired including everything that Adsafe were going to do for $500. New rollers (not made in China) which is what Adsafe said was all I could get if I employed someone else or went to Bunnings. Track machined and new one installed. All that Adsafe said they would do for $300 less. As a customer I expect that if spending $800 I am entitled to know my door will work properly, that I am given an invoice with parts and labour costs and that my questions are answered in a polite manner. Very poor customer service and not honest with their quotes. Update on Adsafe Doors. Received a further reply today after so many weeks. Just to be clear, Adsafe will only quote you prices over the phone. They do not come out to even look at your doors. They have a one price $800 that fits all jobs. I can only comment on my experience with this company. My sliding doors were repaired for $500 compared to the $800 Adsafe were going to charge. If you need sliding doors fixed save yourself money and ring the Sliding Door Doctor. Excellent service, prompt, friendly and very professional. My doors slide beautifully. I would not ring anyone else but the Sliding Door Doctor. Save yourself $300.

Fabulous customer service and arrived on time. Our sliding door was noisy and hard to open. The rollers at the bottom of the door were no longer working. They were quite tricky to remove and replace but for Stephen and Jess it was all in a days work. Extremely professional and would highly recommend this company. Thank you Mark and Jo - Kellyville

Wanting to thank Steve and team for the excellent service I received for my heavy, broken sliding door. The communication was great, they arrived on time and replaced the door frame tracks, realigned the door itself and fixed the locking mechanism in 1.5hrs. Amazing! Highly recommend this business and would definitely be calling on them again if we had any other problems. Thankyou.

Bit more expensive than what I was expecting. But the door is now better than what it was new. So silent and smooth. Feels like a much more expensive door than what it is. So very happy with the outcome. Would recommend to anyone. Job was done very quickly and professionally.

Should be 10 stars. Brilliant service from Stephen and Jessie. Our stacker door was not rolling very well. Stephen and Jessie fixed it so well that it is like a brand new door. Their customer service is fantastic. It is great to see an honest and reliable company. When you have sliding door concerns Adsafe is the company to call.

Our 25 year old glass sliding door had collapsed in its tracks and required urgent surgery. A phone call to Stephen at Adsafe Doors soon had help on its way. Over the phone Stephen gave an accurate estimate and set up an appointment. Stephen and Jessie arrived right on time and got to work straight away. Quickly and expertly the door was removed, a new track was laid and new rollers installed. The door was then replaced on the tracks, fine adjustments carefully performed and the locking mechanism aligned. Then to complete the job Jessie conducted a complete clean up and no mess was left . Now the old door slides like a new one and the lock works perfectly. We have no hesitation in recommending this experienced team of workers.

I have this old aluminium sliding glass door. After years of repairs and never lasted long. Today I called around 4 companies, no-one was helpful. One company stated minimum $4,200 + per job or above if I accept they would send a person to come and measure. I finally got to Stephen on my 5th call, he took the time to understand my situation and given me options to considered. He suggested instead of replacing the whole door and glass unit, let's see if he could fix it instead. Stephen came as he promised and he fixed my door beautifully with absolute pride in his work. The best of it - the cost only a fraction of what others company have quoted me. THANK YOU Stephen and Jessie.

Our sliding door at home had been broken for months and got so bad, it worked better completely off of it's sliding tracks. But after getting in contact with Adsafe Doors, Stephen and Jessie were to the rescue by the following afternoon. They were both incredibly friendly, efficient and had the door back on and working very quickly. I would highly recommend them to anyone in need of sliding door repairs :)

I had a sliding door that refused to slide and a sliding security door that constantly came off its track. Stephen from Adsafe came out, fixed both doors and charged less than the original quote! I now have two doors that slide easily and a security door that provides security! Not only was the work completed quickly and professionally, but Stephen also rang to advise me that he was going to be a little later than the agreed time, due to traffic. Thanks for the excellent job and professional service.

We are so pleased with the repair done by Stephen to our sliding door. It would barely move before (and wouldn't lock) and was hanging lopsided, to now sliding perfectly. So pleased with this service. It is better than ever. The whole service from the first phone call where Stephen recommended ways to secure our place until he could repair the door to cleaning up properly before leaving was exceptional. We highly recommend Adsafe.
