UK homeowner rips up dog-smelling carpet, then finds damp patches and a rotting corner

A U.K. family thought they were doing a routine pre-move upgrade when they pulled up dog-smelling carpet in two ground-floor bedrooms of a house they had bought.

Instead, the new homeowner found damp-looking patches underneath and was already facing a £750 (about $994 at current exchange rates) bill to clear blocked gutters and remove roof moss.

Here's what to know

On Reddit's r/DIYUK subreddit, the homeowner said they'd booked a contractor to unblock the gutters and deal with "extensive moss on the roof" for £750, but the family wasn't sure whether they'd also need a drainage specialist. The post said the property had been empty since June and had already seen several wet days while the gutters were fully clogged.

The floor itself was the main worry. The poster asked if the discovery looked like "a 'thousands of pounds of sealing the floor' job" or something more manageable, while stressing that there did not appear to be any "soaking wet areas."

"I'm spiralling a bit," the homeowner wrote, adding that the family had "almost no money left for repairs" after receiving less than expected from the sale of its previous home.

Replies split between benign and more serious possibilities. One commenter wrote that "the most likely explanation is that the previous owners washed the carpet because it smelled of dog and could see stains when they cleared their belongings." Others said the pattern could still fit a drainage or plumbing issue.

More background

The poster later reported another clue elsewhere in the room: a "damp corner by the electricity meter" had appeared. "The grippers in the corner are rotting, and there's some salt on the concrete," the homeowner added.

That prompted more concern from commenters. One said the "paint above the pipe is blown off the wall" and that "the copper is corroded," while others focused on the exterior and said the render and ground level looked too high against the wall, potentially bridging the damp-proof course.

Before buying the property, the family had commissioned only a level 2 homebuyer report. According to the poster, that survey recorded "mid range damp readings" in a dressing room at the end of the house next to a hill, and the bedroom with the exposed floor sits beside it as the family gets ready to fit new carpet.

What can be done?

Immediate plans centered on water management. The gutter and roof work was already booked, and the homeowner was weighing whether to have someone inspect the drains serving the guttering. Multiple commenters said the new carpet should not go down until it was clear whether the floor was still damp.

Some advice focused on avoiding extra expense. One commenter suggested the family could "empty gutters and down pipe yourself" and "Dig out a trench along the bottom of the walls," adding, "Boom, a weekends work and £0 spent."

Another person made a similar point about cost, saying that for a homeowner short on cash, hiring a ladder might cost "less than 10% of the cost" of paying somebody else.

Elsewhere in the thread, commenters advised pulling up the old carpet and underlay, holding off on the replacement flooring, running a dehumidifier in the center of the room, checking whether the patches dry or reappear, and inspecting the radiator pipework before covering the floor again. The homeowner said the first outside step would be to dig away some of the gravel.

One commenter wrote: "It's right to worry it's a new house and you're still working it out. If it is damp, 9 times out of 10 its very fixable. It's when someone leaves it and ignores it for years it gets expensive."
