A couple say they have been forced out of their home by mould which has grown on their furniture.
Binman Daniel Pedge, 28, has been periodically suffering nose bleeds, which he blames on the state of the property in Locking Close, Doddington Park.
And his teaching assistant wife Hayley, 25, who is currently having IVF, is concerned about exposing herself to possible infection and stress.
Condensation has caused mould to build up inside the drawer of a new bed, on the back of a new wardrobe and bedroom cabinets and in the corner of a ceiling in the main bedroom.
A damp smell fills the house and there is black mould on a section of skirting board in the living room and behind the toilet.
Lettings agent, Lighthouse Property Services, told the couple there was nothing wrong with the building and suggested they open windows and wipe down surfaces after having a bath to get rid of the mould.
But the City of Lincoln Council has ruled the building does have defects which are causing the mould and has informally suggested it fixes the problem by improving the ventilation.
The couple say £1,639 worth of their property has been ruined, including a settee, clothes and Mrs Pedge’s handbags.
Mrs Pedge, who has asthma, said: “We moved out because we don’t think the house is fit to live in.
“It makes no difference how much I cleaned, and then there’s the smell.
“We first told Lighthouse about our concerns last winter and double glazing was installed in January this year.
“We decorated in April and our new bedroom furniture came in July but then the mould started coming back in September.
“We lost our deposit to get out of the property and owe £450 rent for November and a £145 re-letting fee.
“But we couldn’t stay in there any longer – we don’t think it’s liveable.”
Mr Pedge said: “I’ve been off work now and again for the past five months with bad nosebleeds which I think is down to the damp.”
Lighthouse Properties said in a statement: “We strive to provide our tenants with the best service throughout their tenancy and we have worked closely with the landlord and tenant to resolve this issue.
“The property was let to the tenant in an acceptable living condition and the landlord has fulfilled his obligation and duty of care to the tenant.
“Despite no obligation to do so, the landlord has invested in the property including the installation of new windows and doors and recently instructed a pacifier vent to be installed at the property to assist the tenants with the management of the condensation.
“The landlord has also offered the tenants the opportunity to leave their tenancy agreement early, if they wish to no longer live there.”
