Sliding doors gap filled with squishy caulk

[Kat3333]

Hi.

We had some new sliding doors put in 11 days ago. Is it normal for a big gap of ~4/5cm (where precious sliding door was) to be filled with caulk that is still squishy to touch? (See photo)

The company are coming round to look at the couple of problems with another window (catching handle, trim has a big chip out of it). Wondering if I need to get them to check this too?

The company are assure-certified (but not FENSA certified) and have really good reviews. But I am starting to worry we picked the wrong company as some of the windows they did 6 months ago have small sections of caulk have come away to create a small gap. Not sure if this is normal?!

Any advice appreciated. Thank you

Well, what would be the alternative for them? Filler will crack.

It's a bit bodgy but replacement windows always are, unless they quoted for replacement joinery in the rest of the room or crafts person level skill it's always going to be a mess underneath the shiny exterior.
Ideally the gap would have been cleaned and packed most of the way, then a layer of caulk beside, as it will be shrinkage which will be the thing that causes it to open up.
It's not something that would be worth getting them back for, just repair yourself when it shrinks back in a few years time.

It will probably be decorators caulk so can be painted to blend in a bit better.

It will probably harden over time.

Depends on the type of caulk used.

Then I guess its an issue of whether you are fond of sliding doors gaps filled with non squishy caulk.

At the end of the day it's a gap. And has got to be filled with something. But should be done in a way that looks professional.

When you say caulk I immediately think of decorators caulk; although this has a bit of give ie it’s slightly elastic, it’s got next to no strength.

In gaps around windows or frames, I think you should be using a frame sealant, similar in appearance and application to caulk, but with much higher strength and bonding ability. It’s more expensive though.
