Importance of Proper Use of Caulk!
While we have previously discussed the choices and manner of caulking, recent projects make me think it is important to stress the issue!
In recent weeks, I have had to do projects that were not our standard fare, which is typically entire bathroom remodeling, changing tubs to showers and replacing leaky shower pans and rebuilding the shower. One such project is a very nice home on the Island of Palm Beach. The owner contacted our offices with a recaulking job. I suggested he contact a handy man, as it seemed unlikely to justify a Certified Residential Contractor, but he explained a handy man had triggered his need to contact us. The handy man, as a favor, while doing some minor work elsewhere, decided to recaulk a black spot in the master shower. he used white caulk, and slathered it on, over the blackened grout. The original grout was a sandy colored grout, so now the homeowner had a jarring splotch of white, edged with black, in the middle of his otherwise cream colored shower!
While I was there, he also had me look at a plaster wall in a hallway that backed up to the shower. The plaster was swollen and mishapened. We agreed to clean and recaulk the shower with an appropriate shade of sanded caulk. (you can find some shades of grout matching color caulk, both sanded and unsanded at Home Improvement stores, but you will find a more complete selection at fine tile stores like D&B Tile). We also agreed to open the hall wall, and diagnose the problem, both the homeowner and I thought there might be a plumbing leak or that a nearby niche might be allowing for water penetration, or both.
When we opened the wall, we found that the people who had rebuilt the shower a few years ago had used a very poor construction method of building the niche in the shower wall. you could literally stick a finger through the gaps at the corner of the wall board! The tilesetter had covered the gaps with tile, and grouted the joints, so from the shower side, the niche looked solid and sealed. Water had been leaking through the grout, which had cracked as it was supported only by thin air! This leak had been an ongoing, many year leak, and had rotted away part of the framing for the niche.
As the homeowner wanted to do a good repair, but was not yet ready to do a complete shower rebuild, we replaced the rotten wood, and sealed the back side of the niche with fiberglass tape and lots of caulk. Then the closed up the wall and cleaned and recaulked the inside of the shower. This should keep his shower water in the shower for the next several years, though we will return annually to check and maintain the caulking, as needed. The moral to this story is that, if the niche had been built and sealed properly to begin with, it would have likely never leaked. if the leak had never occured, the black spot would quite possibly have never developed, and the homeowner would not have spent in excess of $1000.00 to save his shower and the adjoining walls and framing!
Today, I visited with a homeowner in North Palm Beach who was having an “outside the shower” leak. He had tested it himself, and made a pretty good diagnosis. Five years ago, when his home was built, the tilesetter had not bothered to caulk the shower prior to the shower enclosure people putting up the enclosure. The shower curb was caulked, but only after the shower enclosure had been installed.
Whenever the homeowner takes a shower, the water splashes onto the door, runs down, and drains out the end of the metal framing and goes thru the unsealed grout at the joint between the wall and the shower curb cap. He is now going to have to pay to remove a shower enclosure, so we can caulk that one inch strip of wall and curb behind the metal framing. Again, this time only a few hundred dollars, but still a lot of money for a problem that would never have happened if the caulking had been done properly. Whoever you end up selecting to do your bathroom remodeling project, always make sure they are licensed, have real references and very importantly, make sure they understand the critical need to properly seal all joints and corners of wet areas. A $3-$4 dollar tube of caulk, applied properly and at the right time, can save you hundreds, or ever thousands of dollars down the road.
