A tip I wanted to give you is to have a humidifier.

The second cause is high indoor humidity, thats why if you have a whole house humidifier the recommended humidity setting is lower the lower your expected outdoor air temperature is, to prevent condensation.

It could come from running a humidifier in the property.

I had a serious water repair completed about 1.5 yes ago and they too the walls of where there was damage and had humidifiers placed in the unit for several days to dry out the support beams.

Got to see inside the sump and it seems kinda - what we used to call - groty.Now, it's not an effluent sump, it only serves the floor drain next to the furnace for AC condensate and humidifier waste water.

I’ve installed Central Air, Boilers, Humidifiers, Air Cleaners, Ductwork, Mini Split System’s.

Not laminate -- we've seen (cheap) floating plank laminate flooring fail multiple times with fluid spills, humidifier leaks, pet accidents, planks coming apart.

And if she's that mold-sensitive (allegedly), maybe it would be better for it to not be there.As a middle road, you could advise her to open the door to let it dry between cycles and run a de-humidifier.

i agree that it adds up. however, if you do some of the work yourself, it's still 5 time cheaper (exaggerating a little) than having someone else do it. i'd not buy locks from WM. the quickset exterior locks at HD are $50 each and come with a deadbolt. i love those (used to love them, now i just like them) since i can re-key in under 4 seconds. quality is really important when tenants are involved. i want things to last. i dont want to replace it again in 4 months.i buy some things online. like condensate pumps, humidifiers. but you can't beat HD prices. $20 for a bath faucet that looks pretty good is a great price.food for thought - imagine how much things would be if 90% of the items were NOT made in china. mind blowing, huh?

My newest property has a "damp basement" no obvious leaks or puddles but after the last heavy rain in Dayton the basement was quite damp. my thoughts are fill in cracks DE humidify clean and seal and paint. some black mold forming. upstairs completely dry no sign of mold etc.What should my next step be?
