Replacing decking with paving?

Hi - we have been offered a decent discount on paving over my existing 20 year old decking as my neighbours have used the same builder. The decking is rotting a bit but it looks ok. I just wanted to canvas opinions on whether its worth paving it?

I haven't replaced mine (had it 15 years now) but would love to have paving done instead of decking. Decking is dangerous in the miserable rainy weather. Would be so much safer having paving slabs done. Good luck if you decide to go for it 😊 hoping one day to do the same when finances allow.

Sounds like a no-brainer. 20 year old decking will be rotting and need replacing in the near future - presumably it only looks ok now because you spend time and money every year on its upkeep. Paving is much more resilient, just jet wash and resand, if required, every spring and occasionally squirt some weedkiller in the joints.

I prefer paving but look out for a common error.

The damp course on your house needs to be at least six inches above tbe finished ground level outside, including paving. It is typically two or three bricks above the ground.

Good paving on a compressed MoT1 and/or mortar bed will be around six inches thick. Some numbskulls lay it on top of the ground, so it is too high and bridges the dpc or heavy rain splashes up from it to wet the bricks.

You will also have gullies, drain covers and manholes around the house, and probably a lid to access the outside stopcock. Numbskullspave over these, or bodge some kind of pit.

For a proper job, you need to excavate first so the finished level will be at least six inches below the DPC. If your house is more than 50 years old, it probably has clay gullies or connectors for the sink drain and rainwater downpipes. These are very liable to crack and leak, especially in houses built before 1944. Thus is usually displayed by damp, or cracked and patched concrete around them, or sunken ground, or paving that sounds hollow when knocked. They will need to be dug up and replaced - a surprisingly simple building job that is a hundred times harder and more expensive if you have to break up nice new paving that has been laid on top. So have them inspected and if necessary repaired first.

The paving should be laid with a slight slope so rainwater runs away from the house. If you hope to park cars on it, you need an extra-deep foundation.

You will find examples and specifications on a website called "Paving Expert"

This photo is not of mine, but I copied the style. The slope to run off rain and dirt prevents it holding damp that encourages moss and black mould.

@PigletJohn thank you for all that, so this is the patio, no cars. I don’t know much about excavating though, how can I approach this?

100% plus decking is a rats paradise!

The decking and and supporting joists needs removing. You cannot pave over decking! Yes, paving is a much better finish. We do have Millboard around our pool on one side but paving on other three sides. Millboard costs though but it’s a good product.

I'd choose paving every time. Was not aware of the possible rat issue with decking and think it looks awful.

The builder will know, if not a numbskull. Look at your house walls for a (typically) horizontal black line in the mortar joint near the ground. Once you find it, it will be at the same height all round the house, unless perhaps you are on a steep hill. You might be able to see it beside a doorway or under a doorstep or above an airbrick. How high above the ground is it?

Has your neighbour been done yet? Did the builder excavate?

If not started yet, identify the DPC and ask the builder how deep he expects to dig out, and if he will be laying MoT1 and levelling it. If he says no, frown and ask what he plans to lay the paving on. Make a note of it and say you have not made up your mind yet.

He might be taken aback that you know something about paving, preferably however he will be pleased and regale you with stories of jobs he has done before. Try to find out where they are and if you can go and admire them.

We did, and I definitely recommend it.

Oldish decking, 12 years or more.

The wood was rotting - both the boards you could see, but also the supporting struts after awhile, so there was an increasing danger of a bit of decking giving way.

We had mice living under it, and a wssp's nest one year.

We coated it regularly with that grit stuff, but even so, in the cold winters it was an ice rink.

Paving = minimal maintenance.

Snoozingnotlosing · 02/09/2026 22:27

Thanks all, I did some digging and found actually that some neighbours weren't happy so I am going to shop around now. The hefty discount drew me in but the bad reviews have pushed me back!!!!

Cruise around you neighbourhood looking for a really nice job, so you can tell the difference, and try to engage the homeowners in conversation.

@Snoozingnotlosing My dm had her short drive done a while ago by a builder who was doing a neighbours drive. It was really good and reasonable. We didn’t shop around but the materials used were good and when dm had to sell it was still perfect. Saved us a job of getting quotes and dh is a civil engineer and he was happy as he wasn’t involved. Not all people who get work done like this get poor work.

Snoozingnotlosing · 04/09/2026 04:43

Hi @MeetMeOnTheCorner , these builders did one neighbour well but the other certainly wasnt. I think had they both been happy, id have jumped at it

@Snoozingnotlosing Best avoided then. But my DM and her neighbour were happy. No one wants poor workmanship though.

IMO decking is out of fashion and attracts rats.

It also will not last as long as stone.
