FAQ - Frequently asked questions:
How to choose your deck stairs?
Deck stairs can bridge height differences in and around the house.
Start by measuring the height difference that you need to bridge.
Carefully read through the different options of deck stairs and choose the right height and thus the right number of steps for your deck stairs.
Chosse whether you wish wooden stringers or metal stringers, and select the type of treatboards .
Now choose the desired width
In our deck stairs configurator you will find all the possible options so that you can choose quickly and without effort the deck stairs that you need.
Which treatboards for your deck stairs?
Our deck stairs can be deliverd with pressure treated pine wood treatbaords or Bangkirai hardwood treatboards
Hardwood is low-maintenance, hard-wearing and sturdier than impregnated wooden steps.
The size of a treatboard varies between 120/145 mm depth dimension.
2 boards per step for ordinary outdoor stairs, 3 boards per step for XL garden stairs.
Thickness from 28 mm to 32 mm, where the width varies between 60 cm and 160 cm.
How many stringers do you need to build your deck stairs?
The stair beam also known as stair stringer carries the steps.
Several stair stringers are needed depending on the width of the staircase.
For a stair of 60cm to 100cm, you need 2 stair stringers, 120cm to 160cm, 3 stair stringers, and for every 60cm wider, 1 more stair stringer.
How to fix the treatboard on the stringers?
Treadboards are available with or without pre-drilled holes, zo that you can fix the treatboards onto the wooden stringers.
The number of screws in the building kit will correspond with the width of the stairs and the number of steps of your deck stairs.
Our wooden steel stringers are deliverd with stainless steel carriage bolts and a washer and nut in order to fix the treatboards to the stringers.
The height difference in my garden does not match any of the heights of the deck stairs proposed on your website. What should I do now?
This is often the case, but it does not have to be a problem for your deck stairs.
In this case you have four possibilities:
- Choose deck stairs that are slightly lower than the height that you need.
The last few centimeters to bridge will be the last step. - When choosing wooden deck stairs it is possible to order a slightly higher deck stairs then needed, and cut some centimeters at the bottom of the stringer ( don't forget to add the thickness of the treatboard to the step). The first step will thus be slightly lower then the following steps, but most of the time that is not a problem.The top of the deck stairs will now connect nicely to your terrace or door.
- When placing deck stairs on a sandy soil, it is possible to slightly bury the stringer into the ground so that the complete deck stairs will be lower.(When installing on soft ground, we recommend laying a hardwood or impregnated floor board under the stringer so that your deck stairs do not sink into the ground later on. You can buy individual treadboards in the same width as your deck stairs on our site).
- We are working on a solution where you can place a pedestal or mini-platform under your deck stairs so that the whole system fits the height exactly to the centimetre you need.
Prototypes are currently being manufactured, please do not hesitate to contact our customer service team for more information.
How much weight can Vinuovo deck stairs support?
We often get this question from our customers, and so we have made a list with the weight per step that our deck stairs can support, very useful information when your deck stairs will be used for example for public use.
First of all, make sure that the deck stairs are correctly fixed to the wall. When intended for intensive use, the best advice I can give is to add support posts under each stringer.
As standard, every deck stair kit is assembled with 2 stringers per 60cm width.
Do you want a stronger structure? Then simply add extra stair stringers. (Don't forget to order extra screws or bolts for the treatboards. 2 screws per stair stringer per treatboard).
Width of the deck stairs | Number of stair stringers | Maximum distance between the stair stringers | Maximum weight per step |
60cm | 2 (standard) | 52cm | 100kg |

Do you have the intention to transport a piano every day of the week over your deck stairs and are your deck stairs higher then 4 steps?
Best thing to do then is to fix a wooden support post under each stringer. We haven't actually done the test ( we do not have any elephants available ) but we are sure that an elephant with piano on it's back could take the stairs without any risk!

How to fix wooden or metal deck stairs against a wall?
Our deck stairs with metal stair stringers have the advantage that there is a lip at both the bottom and top of the stringer with 2 holes.
As a result, you don't need a mounting bracket or anything, just insert thick TKS stainless steel screws and secure!
Do you want to use a different screw or bolt? Then just remeber that the holes in the lips of the metal stringers have a diameter of Ø10mm, so make sure you use a screw with a large enough head.

How to fix metal deck stairs in concrete?
When you have just a good, solid concrete wall or floor, then fixing the deck stairs with metal stringers is real easy:
- Per stair stringer, buy a package of 4x heavy duty galvanized screw 8x65mm
- Drill holes Ø8mm and 70mm deep in the concrete and on the right spot
- Schrew the screws through the stair stringers into the concrete and the job's done!
(You won't even need plugs
Thanks to the specially developed thread, they have an excellent grip in wood and concrete and everything is literally stuck afterwards!
How to fix metal deck stairs in wood?
Fixing deck stairs in wood is real easy.
Just pay attention that your wooden wall or floor is thick enough for your deck stairs.
Now of course, you need to know how thick the wood needs to be... Well, preferably at least 40mm, or more.
Do you wish to screw the deck stairs against terrace boards ? These are often thinner....
In order to fix metal deck stairs onto the floor this will not be a problem, there the screws only have to avoid that the deck stairs slide away.
However, for the fixing to the wall this is different, since there will be much more pression on the screws. When the wood is too thin, the metal deck stairs will slowly but surely pry loose from the wooden wall.
In case you are able to reach the backside of your wooden wall, it will be wise to add an extra board, or a wooden post so that you will be able to screw the screws in much further and have more grip.You could also do this on the front side of course, but it will be useless, the screws of your extra terrace board or post will not go any further into the wooden wall.
We suggest for you to choose for 4x Hardwood screw stainless stell with wafer head per stair stringer. If your wood is thicker then 40mm, then don't hesitate to choose a longer screw, the longer, the stronger!
How to fix metal deck stairs in a hollow stone wall?
Fixing deck stairs in a hollow stone wall can be a tricky job...
Before reading our tips and tricks, please find here the difference between fixing metal deck stairs and wooden deck stairs:
- The metal stair stringers have a lip at the top and bottom with 2 Ø10mm holes
- Per stair stringer, use 4x Hardwood screw stainless steel with wafer head Ø8x60mm
- Take Fischer Duopower plugs Ø10x50mm (unfortunately not yet available at Vinuovo)

How to fix wooden deck stairs in a wooden wall?
This seems to be the easiest wall....just a couple of screws and fix the stringers of course!
Eeuuh, yeah, right, but still quite a couple of possibilities are possible...
On the picture here you can see a little wooden wall of a customer who asked us for advice.
Please read here below our questions and tips & tricks:
Do you still have an access on the backside of the wooden wall in order to fix the wooden deck stairs?
(totaaly impossible on this picture, Dagmar would have to dismantle the complete terrace which of course is impossible)
Answer: Yes, I still have access on the back side of the wall.
Great, I like that! Whether you wish to install your wooden deck stairs agains a wooden wall like on the picutre, or against a large wooden post, when you have an access on the back side just screw in two Ø8mm hardwood screws stainless steel with wafer head from Reisser , and the job's done!
Sorry, might seem easy, but still....just a few tricks & tips:
- Which screw length do you have to choose?
Make sure that the screw can be screwed into the stair stringer for at least 80mm.
Is your wooden support less then 30mm thick?
Then select the TKS schrew with a length of 120mm.
Drill a hole of Ø6mm through your wall into the stringer ( oviously place the stringer at the right spot ) and drill 70/80% of the door jouw wandje in de trapboom (trapboom uiteraard exact op de juiste hoogte zetten!)and drill 70/80% of the remaining screw length deep into the stringer to prevent it splitting.
I've lost you again I think, just a calculation example:
- your wall is 27mm thick
- your screw is 120mm long
- 120-27 = 93mm
- 93 x 0.7 (=70%) = 65.1mm.
- So you are drilling about 65mm deep into the stringer. Don't worry, that really doesn't come down to the millimetre exactly!
- and then how do you know how deep you are drilling? In this example, take the wall thickness of 27mm + the drilling depth in the stringer of 65mm = a total of 92mm.
Fix your Ø6mm wood drill bit in your drill and measure from the tip 92mm. Draw a line on the drill bit with a marker. Drill through your wall into the stringer (please drill straight ;-)) and stop when the line of the marker touches your wall. Again, doesn't come to the millimetre exactly, don't panic!
Then screw in the TKS screw and secure the stringer. - Sorry, again I am not thinking... I ask you to use 2 screws per stringer and now of course you want to know at what height you should drill those holes now....
Suppose you have a stair tree of 4 treads, 68cm high.
The height of the piece of wood hitting the wall is about 13cm. I recommend you stay 2-3cm from the outer edge or.
The hole for the highest screw: the stringer is 68cm minus 3cm = 65cm high
The hole for the lowest screw: the stringer is 68cm minus the height of the wood 13cm, plus 3cm = 58cm high - Of course, try to drill in the centre of the stringer and as straight as possible, underneath you run the risk of the screws in the external staircase coming out on the side or the wood tearing out.
Ouch, you still think this is way to technical and complicated? Then just place the support posts underneath your deck stairs, and you're good to go.
But... when the deck stairs are freestanding with support posts, they can slide away, right?
Yes, right, they could! If you want to avoid this, fix the support posts back to your wooden wall with small corner brackets, so you don't have to reach at the back, even easier! Then the deck stairs can't slide away and stands firmly on its legs.
It turned out to be a long story after all, and this was the simplest solution for attaching deck stairs to a wooden wall!
You don't have acces to the backside of your wall in order to fix your deck stairs wood?
Not to worry, we also have a solution for this situation!
What is important is that your wooden all or wooden post is thick enough and of good quality, just solid wood, not old and not half rotten.
So what is thick enough?
We will explain here under for each separate solution.
Fastening brackets
Fixing the stair stringers wit galvanized fastening brackets would definietly be the easiest and the cheapest way.
Not the strongest solution, but if the deck stairs are just occasionally used, not a problem. This way of fixing is not strong enough for professional use !
Suitable voor a minimum depth in the wood of 27mm.
When the surface of the wall is irregular, it may be difficult to place the bracket straight.
Mounting bracket
A steel mounting bracket is very solid and thus a perfect solution.
Unfortunately, they stay visible thus less attractive.
For sturdy mounting, you need a minimum wood thickness of 50mm.
The stainless steel screws you need for mounting in wood are included.
How to fix deck stairs in a hollow brick wall?
When you see a stone wall, it gives you a solid impression...
Unfortunately this is not always the case! Especially when it concerns a hollow brick wall, which is often the case with modern stone walls that are build with hollow bricks. We'll show you some examples here below:
PLEASE PAY ATTENTION: never fix deck stairs against a plaster wall, this is really not strong enough!






How can you find out if the wall behind your deck stairs is hollow?
You can tap it (softly) with a hammer, then you will usually hear it.
You'll know for sure when you put the drill in! Does your drill shoot through quickly, crumble the edges of the stone and then your drill floats in all directions?
Then you are in a hollow wall and have a problem fixing your outdoor staircase!
There are solutions to problems, but they are not always easy.
Below, we will give you a few solutions to fix your deck stairs firmly in a hollow wall.
Our approach may differ slightly from the fastener manufacturer's tips, depending on which product you buy. Follow the manufacturer's instructions as much as possible.
What do you need in order to fix deck stairs in a hollow brick wall?
- To start with; our mounting bracket to be screwed against the wall.
To order, click on the image. Order 1 piece per stringer of your deck stairs, or 2 per stringer if you also want to use this mounting bracket for the floor mounting of your deck stairs.
The mounting bracket for deck stairs comes with stainless steel screws Ø4x50mm. Per bracket, 4 of these screws go into the wall, so you need to drill 4 holes per bracket and provide them with plugs. - Hollow wall plugs or chemical anchors so that your deck stairs can be screwed safely and securely into the hollow wall.
The biggest problem now is that you have to drill a lot of holes and need a lot of plugs. This is not so bad with a solid wall, but with a hollow wall it can become very tricky.
Unfortunately, I can't say how tricky, that really varies from wall to wall, and even from brick to brick.




How to attacht the stringers to the wall now?
- Unfortunately, you will first have to choose which type of plugs you want to use.
We will show you below some solutions and how to use them to fix your deck stairs. Unfortunately, we cannot give guaranteed advice without drilling into your wall ourselves.
Sometimes it can be easy. In the next steps, we hope it's easy, if it's not, we'll come back with a possible solution to fix your deck stairs. - First mark the holes for the mounting brackets on the wall.
(The location of the mounting brackets obviously depends on the height of your deck stairs and exactly where you want to place the stringers). - Start with a small Ø6mm concrete drill and drill 50mm deep.
When the edges of the hole look solid, even with a hollow space behind it, you can insert Fischer Duopower plug Ø6x30mm there.
I generally have very good experiences with this plug. If your wall is really bad, this plug will not be sufficient.
When you find that there is a really large hollow space behind the first stone layer, the Fischer DuoTec plug comes highly recommended. This plug tilts behind the first stone layer and thus secures itself to a large area. But this only works if there is enough space to tilt the plug.
(Unfortunately, we cannot yet supply the Fischer Duopower and DuoTec plugs). - Secure the mounting brackets with the screws in the dowels and check that they are really tight!
Crap... Are the mounting brackets for the deck stairs not secure yet?
Bummer! Now it gets trickier...
Have you tried the Fischer Duotec or do you not have enough space for that behind the first brick layer?
If the Duotec doesn't work either, there's nothing left but to go with a chemical anchor or injection mortar.


Wall mounting of deck stairs using a chemical anchor or injection mortar
When an ordinary plug spins out of control or simply does not work in a hole, you have no choice but to use a chemical anchor or injection mortar.
These are products that consist of 2 components. A filler and a hardener, usually based on synthetic resins. They are sold in cartouches that usually fit in a standard caulking gun. The special nozzle on the cartridge mixes the 2 components when you spray it into the hole.
Because of the mixing, the filler hardens quickly (usually within 30 minutes) and your screw or plug is locked in place!
OK, but how can you use those products to fix your deck stairs?
First a question: is the wall hollow or just in really bad condition?
(Poor condition: crumbly stone or a porous brick that cracks out when you put a plug in it)
Use a chemical anchor to fix your garden stairs in a HOLLOW wall:
When the wall is hollow, you need a sieve plug. This is a special plug with holes. When you inject the chemical anchor here, it goes out through the holes and fixes itself behind the various layers that may be in your wall.
Using a chemical anchor to fix your deck stairs in a FULL wall but in poor condition:
Just spray it in, the chemical anchor fills all the small spaces between grains of stone and so on and glues everything together, reinforcing the wall and making your deck stairs wall tight anyway...
Ah, good! A cure-all, then?
Yes, in itself, but just wait a little before cheering out loud;-)
- If the mounting brackets for your deck stairs are not tight with only a few holes, you can try spraying some "stuff" in those holes, insert a new Fischer Duopower plug and let it harden.
Then insert the screw and hope the plug stays in place. (Note, you can't reuse the DuoPower plugs.... If you had to loosen the other screws to remove the mounting bracket from the wall, you will have to put new plugs in the other holes as well! Then spray some chemical anchor in there as well, because the wall may be damaged by the first fastening...) - Chemical anchors are designed to insert studs. You let the anchor harden and then you slide the material you want to attach over it and secure it with a nut.
So that doesn't work with the mounting brackets for our deck stairs! It does work perfectly when you use a metal stair stringer, by the way!
There is no room inside the mounting bracket to screw a nut onto the stud... if you do succeed, there will no longer be enough space to insert and secure the wooden stringer.
But we have a solution for that too;
- place your sieve plug in the case of a hollow wall, or inject the chemical anchor into the crumbling hole.
- Insert a DuoPower plug Ø6x50 and allow to harden, the DuoPower plug is then firmly in place. Then use the screws supplied with the mounting bracket to screw it into the plug.
- Have you chosen metal deck stairs? Then use stainless steel TKS screws Ø8x60mm and Duopower plugs Ø10x50mm
Did you succeed? Bravo! You can now call yourself a real do-it-yourselfer as far as I am concerned!




How do you fix deck stairs in brick, pavers or tiles?
Normally, you can just use plugs and screws to fix your deck stairs to a wall or floor made of brick, paving bricks or tiles.
For wooden deck stairs, use the mounting bracket or fastening brackets, and matching plugs, for more details have a look at: How do you fix deck stairs in a hollow brick wall?

Note: Plugs push to the side when the screw is screwed in, this way the plug fixes itself in the stone. With brick, bricks and tiles, there is a risk that the stone will crack, especially if it is older and porous.
If that is your case, drill holes that are Ø5mm wider than the plug, inject some chemical anchor into the hole and insert the plug. When the chemical anchor has hardened, you can fix the deck stairs in the holes with screws.


How do you fix deck stairs on gravel or a lawn?
Well, that's tricky!
In any case, make sure that your deck stairs are fixed to the wall in an excellent way, fixing them to the ground is of less importance.
But you do want to prevent your garden stairs from sinking into the gravel, sand or grass!
Of course, you can go hard by pouring a concrete base on which your deck stairs will stand. That's certainly a good solution, but also a lot of work.
You can also dig a thick garden board (preferably hardwood) or thick wooden beam into the ground under your garden stairs. The weight of the deck stairs and users is then spread over a large surface area, so there is hardly any chance of sinking. (To be clear, a concrete base can also sink).
Do you still want to fix that beam or plank in the ground? Then you could use a ground anchor, but that seems a bit redundant to me personally.
