Hello,
I am in the process of purchasing a house. Our inspector found high moisture readings behind the ensuite shower tiles, the sellers brought in their own inspector. I am just wondering if any professionals can give me some insights here on whether there looks to be an issue here or not. I have copied and pasted both inspectors findings related to this specific issue.
Thanks for your help.
OUR INSPECTORS REPORT
Ceramic tile. High moisture readings were observed behind the tiles at the lower 3 sets of tiles at the left and right walls and the side of the door and about 4-6 ft high at the rear wall at the time of the inspection. This is an indication of water penetration behind the tiles and damage to the wallboard. These readings were approx. 20 to 90%. Recommend review by a licensed professional for repair or replacement as necessary.
THEIR INSPECTORS REPORT
2.2 (1) The shower in the master ensuite showed no visible signs of leaking, in addition, none of the grout was cracked or missing. The humidity levels that I received on the thermal camera (reference only) were in the low 20’s. Showers in general will always have fluctuating levels of humidity, especially ones like the enclosed shower in the master ensuite. Grout will typically hold moisture for 48-72 hours and if used on average twice a day everyday, the grout never really has the time to fully dry. Although there are no concerns for leaks at this time, re-sealing the grout is good practice for home maintenance (let the grout dry for 48-72 hours prior to sealing). Be sure to read the sealant specifications before using the shower again as they could require 24-72 hours depending on the brand used.
