One of the most common problems found with newer homes today is faulty or failing tile enclosures. The probability of finding defects at these locations from an inspection perspective will depend on the location, extent of use, methods of installation and maintenance. Sometimes these defects are not visible following non-invasive inspection techniques.
From experience we know that showers are used multiple times a day. We also know that little or no maintenance is ever conducted by the homeowner, so grouting & sealants deteriorate faster and moisture begins to penetrate behind the tile. Once moisture gets behind the tiles, it is very difficult to correct. The average cost to retile a shower enclosure is well over $1000. Homeowners should check their shower enclosures regularly for loose grout or tiles and have repairs conducted as soon as possible.
Where large windows are present within the enclosure and shower spray, these should be provided with a positively sloped sill and be sealed on a very regular basis. Normally these openings are the cause of most premature failures particularly on wood framed structures.
Shower Enclosure Maintenance
(1) Check grouting regularly and regrout tile as needed;
(2) Recaulk all junctions, enclosed joints & corners as needed;
(3) Check perimeter baseboards and carpet tacks adjacent to the enclosure;
(4) Pay close attention to the areas within the shower spray and splash zone.
Some Builder Faults to Look for:
(1) Wrong wallboard used behind tile (not moisture proof);
(2) Wrong glue used for tile adhesion;
(3) Floor not laid to drain water away;
(4) Wrong caulk/sealant used within enclosure.
(5) Large windows or openings within the enclosure.
