Student rentals, heavy occupancy, and one August window
Mold, Water Damage & Painting in Durham, NH
Durham's housing market runs on the UNH calendar. A large share of the town's rental stock is occupied at high density nine months a year, emptied in a few days, and has to be turned before the next group arrives — which puts every repair, repaint, and cleaning into the same narrow window.
What we see in Durham buildings
Occupancy load is what makes Durham different. A house built for a family of four holding six or eight tenants generates several times the moisture — showers, laundry, cooking, and simple respiration — through ventilation that was sized decades ago for far less. That shows up as condensation on windows, damp bathroom ceilings, and growth in closets and on exterior-wall corners in units that have no leak at all. Meanwhile the older homes along Main Street and Madbury Road carry the usual Seacoast issues, and property near the Oyster River and out toward Durham Point deals with high groundwater on top of it. The compressed August turnover means problems that built up all year get discovered and have to be fixed in the same two weeks.

My rental has mold but no leak. What is causing it?
In heavily occupied student housing the moisture source is usually the occupants themselves. Eight people showering, cooking, and doing laundry in a house ventilated for four will push indoor humidity high enough to grow mold on cold exterior-wall surfaces with no water intrusion whatsoever. The fix is ventilation and humidity management alongside the remediation — otherwise it returns the next semester.
Can you turn multiple units in the same August window?
Yes, if we have the dates early. August in Durham is fully booked by mid-summer, so landlords who reach out in spring get scheduled; the ones who call the week of move-out usually cannot be accommodated in time.
A tenant reported mold. What should I do first?
Respond and document. New Hampshire's rental repair timeline under RSA 540:13-d gives a landlord 14 days, or sooner as conditions require, to address a condition a tenant has reported in writing. Practically, that means acting quickly and keeping a written record of what you found and what you did. If you want an independent opinion on the extent of the problem, a certified assessor can sample and interpret it; our role is the remediation and the documentation of it.
