How would you solve this threshold?

[snowjim]

Hello,

We had a craftsman here today who installed a door for us. This meant that he had to cut a bit of the concrete.

Fortunately, the door ended up a bit higher than we desired, which resulted in a 5 mm gap at the bottom.

The craftsman's suggestion is to raise the threshold, this is what it looks like:

You can see here that he marked on the frame, probably considering lowering the frame somewhat himself.

Here you can see that the frame goes up a bit into the concrete, and the idea is to place a cover strip here since they are level with each other.

The other side of the door, this is the direction the door opens (if it wasn't clear).

Personally, I don't like thresholds, but in this case, we have chosen a frame with sealing to block out at least some sound (even though it is a glass door). To achieve the best effect, it means it should be sealed even at the threshold. Currently, that isn't possible since the door is mounted too high, and as mentioned, the craftsman's suggestion is to raise the threshold.

The problem with raising the threshold, besides not liking high thresholds, is that we have a robot vacuum cleaner that should be able to get over it. Perhaps this can be solved with rounded strips that make it easier to get over.

Lowering the frame now is probably not possible given that it only involves 5 mm and the holes in the walls are already drilled.

So the question is, would you raise the threshold 5 mm and add sealing, or would you live with the threshold not quite reaching up?

Otherwise, we are very pleased with the work!

Is there a "borstlist" that you can screw under the door and in that way avoid touching the threshold.

 

[snowjim]

Hehe nah, it becomes even more obvious that something isn't quite right. Also, I don't know what the brush would solve? It's not likely to help with the sound.

Do you have any of those in your house?

As you said yourself:

Raise the threshold or remove and saw off the frame will probably look best as the lintel comes down a bit.

nail a strip to the underside of the door. If the strip is slightly thinner than the door leaf, no one but you will know it's there.

If you are missing sealing strips between the door leaf and frame, those five millimeters will not make a difference in terms of sound insulation.

 

[snowjim]

If you lack sealing strips between the door leaf and the frame, those five millimeters won't matter from a soundproofing perspective.

Yes, the rest of the frame has sealing strips as I mentioned above. Otherwise, I probably wouldn't care about this.

As you said yourself:

Raising the threshold or removing and sawing off the frame is probably the most aesthetically pleasing since the top piece will come down a bit.

Yes, it's probably only I who can decide this, was just wondering if there was an obvious choice. If the frame is to be lowered, I suspect that it first needs to be removed, then you would have to fill in the holes from the previous plugs and screws. After this, you can drill new holes that are 5 mm lower and thus make it more "perfect."

Should I perhaps bring this up with the craftsman, or is the job adequate despite this?

 

[thomas33]

Hehe well, it becomes even more obvious that something is not quite right. Besides, I don't know what the brush would solve? It surely won't help with the noise.

Do you have any of those in your house?

I copy and paste;
Brush strip
Brush strip is used for sealing doors and gates. The strip provides protection against soundproofing, protection against insects and pests. Sealing against dust, dirt, water, and smoke. Cleaning of conveyor belts in industry.

The threshold is already too high. I would have cut the frame. Preferably switch to a thinner threshold.

 

[snowjim]

The threshold is already far too high. I would have cut the frame. Preferably replace it with a thinner threshold.

What do you mean by it's already too high? Right now you could say it is just above the parquet level.

 

[Lars48]

How do you mean that it is already too high? Right now you could say that it is just above the parquet level.

I mean the threshold itself is too thick. If you lower the frame then you might as well choose a thinner one.

 

[snowjim]

I mean the threshold itself is too thick. If you lower the frame, you might as well choose a thinner one.

As far as I know, there are 2 different thresholds, the one we bought which has a lip against the door and one that is much thinner and lies flat under the door without a lip. Since the thin one lacks a lip, you also can't put any sealing there, and that's why a threshold with a lip is required. That's why we chose this threshold. We actually don't like thresholds, and if the threshold doesn't serve any purpose (soundproofing), there's no reason to have one as wide as ours. But I suspect if we just buy a small threshold now, it will be too noticeable that the door is hanging in the air.

I still think I need to discuss this with the craftsman and possibly pay for another hour's work if he is willing to lower it.

Otherwise, I agree that the threshold is high as it is; you certainly don't want to raise it further as the craftsman suggested.

As far as I know, there are 2 different types of thresholds, the one we bought that has a rim against the door and one that is much thinner and lies flat under the door without a rim. Since the thin one lacks a rim, you also cannot place any sealing there, and therefore a threshold with a rim is required. That's why we chose this threshold. We don't really like thresholds, and if the threshold isn't serving any purpose (soundproofing), there's no reason to have one as wide as we have. But I suspect that if we just buy a small threshold now, it will be too obvious that the door is hanging in the air.

I think I'll have to discuss this with the craftsman and perhaps pay for an additional hour of work if he is willing to lower it.

Otherwise, I agree that the threshold is high as it is, and you wouldn't want to raise it further as the craftsman suggested.

If the craftsman did this, then it is not approved. He should redo the job for free, I think.

Kanta on the door is the best suggestion in the thread. The edge can be equipped with a saw track strip, and the sealing is done. The edge does not need to be glued but can be painted in advance and screwed on.
