See the light brown water marks on the ceiling? This is right below the upstairs bathroom. Yup, it's leaking probably due to the holes in the floor grout.
Fortunately, I called Maricel of Rabacon (contractor who installed everything in said bathroom), and she sent a couple of workers over to seal the gaps. Though, I was also thinking that maybe the holes are due to the bathroom tiles or the toilet not being installed properly? This assumption is based on the backyard roof which also had leaks while a similar, but older, roof made by Avida over the front door never had a problem. And speaking of front doors, the red front door they installed warped and cracked after a couple of years.
So, I was a little wary of calling them to fix things since they didn't do a good job to begin with. But Maricel mentioned that I should have called her to repair the roof and the door which they would have done for free. Considering all of our expenses thus far, I was thinking, maybe it’s worth a shot.
Also, the previous village manager, Engr. Froilan, once mentioned that things inside a house will start cracking due to the heat especially if the house is closed and hot air has nowhere to escape. So that might be another possible explanation, though not even the workers who came over know for sure. Well, let’s see if this will work.
