Before you list
A 5-point moisture check for Londonderry homes
Londonderry homes sell fast, and these are the spots inspectors check first. Catch them before the buyer’s inspection does.
- 1
The attic
Look for dark staining on the roof boards, especially near bathroom fans and the eaves.
- 2
Bathroom fans
Make sure they vent outside, not into the attic, which is a top cause of attic mold here.
- 3
The basement walls
Brown lines or a musty smell near the floor often mean water is wicking up behind finished walls.
- 4
Sump pump & water heater
Test the sump and look for rust or drips under the water heater before they fail.
- 5
Gutters & grading
Overflowing gutters and soil sloping toward the house send rain straight to the foundation.
Recent work in Londonderry
A flooded basement
Basement floods are one of the most common calls we get from Londonderry. Getting the water out and the space properly dried in the first day or two is what keeps a flood from turning into a mold problem weeks later.
Londonderry homeowner notes
What’s happening in Londonderry, and what it means for your home
Updated October 2026 · Source: Town of Londonderry
Old Nashua Road water main work
The town posted that Pennichuck Water is installing a new water main on Old Nashua Road through November 2026. If your water is shut off or pressure changes during the work, check under sinks, behind the washer and around the water heater for drips once it comes back.
Selling this fall or winter?
Attic mold is one of the most common things inspectors flag in Londonderry colonials and capes. If it comes up, Jeremy can scope it fast and finish before closing, and sellers can pay at closing.
Rebuilding after water damage?
Once cleanup is done, check with Londonderry’s building division about permits before putting walls and floors back, so the work is documented if you ever sell.

Londonderry questions
How fast can you get to Londonderry?
Londonderry borders Windham, so it’s one of our quickest drives. Usually same day, and 24/7 for water emergencies like a flooded basement.
The inspector found attic mold. Will it come back after you remove it?
Not if the cause is fixed. Jeremy finds why the attic is holding moisture, like a bathroom fan venting into the attic or blocked soffit vents, and the 3-year warranty transfers to the buyer.
Our basement flooded. What should we do first?
If it’s safe, stop the water source and move valuables up. Then call or text Jeremy right away. Drying fast in the first day or two is what keeps a flood from turning into mold.
Can sellers pay at closing?
Yes. Sellers can pay at closing, so the work gets done before the closing date without anyone fronting the cost.
