Hi Chris:

I was so happy to see your website and was wondering if u can give me any advice.  I have a fixed shower panel where it is secured at the bottom with U Track type of metal. My contractor guys forgot to seal it in the beginning so water got in and leaked outside.  After I informed them of the problem they came back and put clear silicon seal around the bottom.  Everything was good for about 6 months.  And now I’m noticing black stuff (I’m assuming it’s some kind of mold) inside the silicon seal and INSIDE the track!  Is there any way I can clean it out?  and after cleaning it out (hopefully) how do i seal again?  Is silicon caulking enough? or is there any kind of seal strip i should add?

thank you very much for your help!



Hi Charlotte,

Thanks for reading my blog. It looks like the caulking was applied after the water was already in the channel. Once the mold began to grow, it was trapped inside. Since the glass is clear, the mold is highly visible… In order to fix the problem, the glass is going to need to be removed from the channel. I would clean it thoroughly, and use bleach to make sure that the mold is completely eliminated. Only then should the glass be replaced, and the silicone seal reapplied. Make sure that the glass and channel are nice and dry before you do so. There is also a type of silicone that is “mildew resistant.” This is the type you are going to want to use. It has a fungicide in the formula, and will help to prevent the mold growth. Apply the silicone where the metal and glass meet to prevent water from entering the channel.

Best wishes,



Drilling Holes in Tile for Shower Enclosures – Preventing Leaks

Chris, I am so glad I discovered your site!

We live in Birmingham, AL and are in the final phase of a major double bathroom remodel. We went very modern with barrier free entries to the shower enclosures. When the glass installers put the glass panels in place, they drilled and secured clips on the floor to hold the glass. When they installed the clips they penetrated the shower pan and now the showers BOTH leak to the basement. They have agreed to repair this but we have a question for you. There are other issues as well – this was a total redo so everything is new, including the walls and as such one of the baths walls is not plumb so they are on the third glass panel trying to make it work. We are six months into a three month project, but do believe the contractors are trying their best and are willing to see this through with them.

I see on your website and others that people everywhere install glass clips in barrier-less showers and surely they do not have water leaking into the floor beneath. The least of our worries is water coming out from under the glass into the bathroom… in fact we do not want sealant because it is unsightly. What has our contractor overlooked? They are willing to fix this problem… unfortunately I do not know enough whether to require them to take out all of the tile and replace the shower pan or use silicone in the screw holes as they are suggesting. They are slathering silicone everywhere and destroying our “look”.

Thank you for any input or suggestions. – Do you travel for installations? OR consultation?




Hi Rollins,

First of all, I am sorry to hear about the issues you are having with your shower doors. I am glad to hear that your contractor is working with you to solve the problem. Anyone can make a mistake… the key is being willing to stick with it to the end.

Putting silicone in the screw holes is the solution to the leaking problem. We will usually apply the silicone to the screw and then run it into the hole. This is an effective way to seal the screw hole. There is no need to slather silicone all over the place, though.

Be sure to document everything, and have an environmental inspector come in after a few months to make sure that you don’t have any mold issues. I do work as a consultant, and do travel when an out-of-area customer feels that it is worth their while to pay my expenses. Let me know if there is an additional service I can provide.

Installing Customer-Supplied Shower Enclosures

From time to time I am contacted by a potential customer who has purchased a shower door or enclosure elsewhere. They have found a “great deal” on a shower door online, or at a local home improvement center. Now they need to find someone who knows how to install it for them. My policy is never to install a customer-supplied shower door. There are just too many things that can go wrong. Online suppliers and home improvement stores are there to sell shower doors to people who are capable of installing them. It’s just common sense that, if you don’t know how to install a shower door, you probably aren’t qualified to buy the right one in the first place. Chances are that the customer thinks they are going to save a little money by buying the materials from one store, and having it installed by someone else. This is a big mistake. A customer who is looking for the cheapest way to do something is a disaster waiting to happen!


I have been doing business with a number of different suppliers for many years. There are a lot of great products available from local manufacturers. On the other hand, there is a lot of cheap crap that is made in China. Odds are that the guy who has done a Google search for “the cheapest shower door on planet Earth” hasn’t come up with a very high quality enclosure. I learned early on that it was a really bad idea to get involved in partnering with people who want to go this route. There are few things less enjoyable then being in a stranger’s bathroom with a shower door kit from some far-off land… hundreds of little parts that are made of inferior metals (or plastic instead of metal!) Instructions that were written by someone who obviously doesn’t speak English, and having the materials crumble under the smallest amount of pressure. Great! Not only have I wasted my day trying to install this piece of junk, now I look incompetent, and have to buy this guy a new crappy shower door and try to get out of this mess! No thank you!

Recently, I let a customer talk me into installing his shower door (bought online). I told him that “I don’t install customer-supplied shower doors.” But he was such a nice guy, and practically begged me to do it. I have a soft spot for people who are in need, and it’s hard for me to say “no.” It had been years since I had agreed to install one of these things, and had forgotten what a nightmare it was to do this. I explained that it was going to be expensive. I went over the price with him a few times to me absolutely sure he understood how much it would cost. To make a long story short, after installing the shower door, the guy didn’t want to pay me. Go figure! It was just what I needed to remind me that my policy is a good one. Never install a customer-supplied shower enclosure.

Help a desperate Aussie!

Dear Chris,

Thank you for your wonderful blog, as a previous poster has said, it’s made it Down Under?

I have a problem I was wondering if you might be able to answer. A contractor recently messed up the caulking on my newly installed frameless shower screen, smearing silicone all over the glass and spreading it well into the grout lines of the freshly tiled floor. The caulk has seeped right in and stained the grey grout black.

The company has apologized and has offered to send someone to remove the excess caulk from the glass. They will not, however, clean up the grout as the manager says this kind of seepage is inevitable due to the nature of the tiles involved (25mm hexagonal mosaic).

Is there really no way around this? Would it not be possible to, say, fashion some sort of barrier to stop the silicone from running along the grout lines?

Best regards,
Melbourne, Australia


Hi Chloe,

Thanks for writing, and for your nice compliments. I am so sorry to hear that you are having problems with your shower enclosure installation. Silicone can be very messy, and it really takes some experience to apply it effectively and neatly. I have a big advantage over other glass contractors because I install shower enclosures almost exclusively. I get a lot of practice with caulking these frameless shower enclosures, so I am pretty good at it.

Still, I will always try to talk homeowners out of caulking the glass wherever possible. No matter how nicely the silicone is applied, it is still undesirable. A frameless enclosure, when properly utilized, shouldn’t require any caulking. Frameless (also called seamless) enclosures are not meant to be perfectly water tight. The environment should be designed to tolerate a small amount of leakage. The frameless enclosure is really designed more to look great than it is to hold water.

The response that you are getting from the company that did the installation is about what I would expect. It may not be ideal, but about all they can do at this point is clean it up as best they can. Since they don’t do tile work, you really don’t want them trying to re-grout your tiles… I’m sure that wouldn’t turn out very well anyway.

Thanks again,


Frameless Shower Enclosures for Bathtubs

These days there are more and more people requesting frameless heavy glass enclosures for their bathtub showers. Several years ago, people began asking if this was a possibility… today, this is pretty common. There are newer innovations that incorporate sliding glass panels with heavy glass enclosures that are suitable for bathtubs. Among these are the “Skyline” series enclosure by Cardinal, and the “Serenity” series by CRL. The latest sliding frameless enclosure is called the “Essence” series enclosure. Click this link – – to check it out.

The enclosures shown in the photos above were designed, manufactured, and installed by Showcase Shower Door. These enclosures are designed according to customer specifications, and include Diamond Seal treatment as a standard feature. Diamond Seal helps to prevent water spotting, and protects glass from the permanent damage that hard water can cause over time.

I’ve read a lot of your replies and it really seems like you really know what you’re doing. I have to replace my concrete shower basin and was curious if I’d be able to reuse the frameless glass doors I have now. They are in great condition but will need to be removed in order to replace shower basin. Any help would be greatly appreciated. If you need pics I can send.

One other question, do you know any reputable contractors in the Chicago area that you’d recommend using to replace concrete shower basin?

Thank you very much for your help!

My son did a beautiful job cleaning up and re-caulking my shower door. We let it cure four days after completing the job because its cold and damp in winter. The caulk seemed sound for about 2 weeks, then began to expand, and get gooey. Nasty! What happened? It is impossible to put latex caulk in an application formerly “occupied” by silicone?
