    LESLIE: Nadine in Iowa has an interesting question. Your countertop has gotten noisy? Tell us what’s going on.

    NADINE: Yes, it does. We had it installed, I would say, between three and five years ago. And right after we had this Corian counter installed, we started getting very sharp, loud bangs occasionally. And I mean like somebody-just-shot-up-the-house bangs. And it has been going on since we had it installed, to varying degrees. Louder sometimes than others.

    But they’ve been out to check and can’t figure it out and I don’t – the only unusual thing that happened when they put it in was that one corner didn’t want to go down, so the guy had to put his full weight on it to push it down and finally make it go down. And my feeling is – or something must be bound in there that every once in a while builds up enough energy to really snap.

    TOM: Well, that’s certainly an unusual situation, because countertops aren’t known for their noise.

    NADINE: OK.

    TOM: We get squeaky-floor questions, we get banging-pipe questions.

    I don’t think we’ve ever gotten any loud-countertop questions, huh, Leslie?

    NADINE: Well, I doubt that it’s the countertop. My feeling is something might be bound in there, having been caused by having the countertop put on.

    TOM: Well, you might be correct and what could be happening is that you could have expansion and contraction going on, either with the walls or even with the plumbing. Especially with the water being right there, when a pipe heats up, it tends to expand. And if it’s attached to the framing very, very tightly, it will rub across that framing and it can make a creaking sound or a banging sound.

    NADINE: OK.

    TOM: And I’ve heard that before in bathrooms and also in kitchens.

    NADINE: OK.

    TOM: The other thought is that if the countertop is bound, as you say, against part of the frame of the house and you’re getting expansion and contraction, that could be the source of the sound. Although, I tend to think that, even though it’s annoying, it probably isn’t really very damaging if it’s one of the other of those things.

    NADINE: No, I don’t think it is damaging at all. It’s just that when you have guests and their eyes get wide and they start to go for the floor, you think maybe – I mean it is quite loud when it does it. So you think it could possibly be plumbing?

    TOM: It could very well be, because plumbing really carries the sound. And especially if you’re running a dishwasher and the hot water comes on, that could cause a noise.

    NADINE: However, we’ve kind of checked that out – what’s on, what’s running and all of that – and that doesn’t seem to come into play. What would your suggestion be as to sleuthing this problem out?

    TOM: Well, I guess I would have to be sitting there staring at it, thinking about it for a long time. But reinstalling the countertop would probably be the best solution, although it’s a boatload of work and you can potentially damage the countertop in the process. If they had to really squeeze it in, I suspect that something is a little bit too tight in its intention and it’s really not designed to be pulled out.

    NADINE: Yeah. Alright. Thanks so much.
