Renovation to be done

[Dominique81]

We have been doing the maintenance ourselves since 2019, but we also noticed that there was black algae in some areas and that some tiles had little grout.
We first looked to see if we could easily do the maintenance ourselves and black algae became less and less, but today I had the first loose tile. I have attached a photo.

By that time we asked for advice and one company could do a renovation of the swimming pool by using a high-pressure cleaning and re-grouting service (scarping out old grout was not mentioned). This came to 600 euros, which I actually thought was cheap and gave me the idea that this was a temporary solution.
Is it true that re-grouting needs to be done once in a while?
For example, is this every 10 years (according to the neighbours, assuming correct products have been used)?
Also, the problem with the black algae will be solved they said, but it seems to me that this can also be sprayed behind tiles with the high-pressure washer and can still cause problems.

Another solution is to cut everything out and have new tiles installed, which is of course much more expensive. If I use the TFP method from the beginning, what is the expectation that a renovation will need to be done?

Ultimately, everything in life needs maintenance and I am looking for the best long-term solution. Can you help me get started in terms of information, so I can find the right professional in my area?

Many thanks,
Dominique

Any algae at all is caused by lack of chlorination, not tiles or grout, you can remove the old grout or apply new grout, but if the chlorine is still low it’ll just come back.

Do you have a TFP style test kit available there? That’s gonna be required to use the TFP “process”.

Sorry, I wasn't completely clear. We bought our house in 2019 and the swimming pool was already 12 years old. I don't know exactly what maintenance has been done. Can only say that black algae was visible in some places and that the joints were not completely intact.

Since 2019, we have been doing the maintenance ourselves according to the TFP method, the values from last Saturday were:
FC 5.5
CC 0
pH 7.7
TA 60
CH 525
CYA50
CSI -0.07

Test kit see signature, TAYLOR K-2006, same as what you have.

Since we have been doing this ourselves, so the last 4 years, FC has not been below 4 (CYA 40-50).

Once there is black algae, it is difficult to get rid of it, if I understand correctly? Or do you mean to say that the black algae should have completely disappeared by now when using the TFP method? It has decreased, but it is not completely gone yet (brushing, robot).

Can you tell me, on average, after how many years a swimming pool needs to be re-grouted?
How does this normally work, lots of cowboys here, so any information is welcome? Perhaps I am overthinking this?

After the work I carry on with the TFP method, brushing and robot cleaning.

You are in a good spot in that case. If the algae is confined to the grout area, you can scrub the grout lines and SLAM the pool to remove the algae and then regrout.

The grout should last many many years if the prep is good. Do it sooner rather than later as the grout it the waterproofing material and so you don’t want water getting behind the tiles and corroding the thinset, Epoxy grout would be a good choice if available.

Can you explain me what are good preparations?
The budget I received says: High pressure wash with acid and water and grout the entire pool with weber epoxy.

Correct me if I am wrong but I think the old grout needs to be entirely removed before applying the epoxy?
