New concerns have surfaced about Winnipeg houses built by Kensington Homes, with some homeowners now raising concerns about their windows and doors.

The CBC News I-Team reported last week that several Kensington homes — which were built in recent years and came with a builder's warranty — had shingles coming off the roofs.

Miranda Wajda, who bought a Kensington-built house in Winnipeg four years ago, says she has had to get the front door fixed or replaced four times.

"There [were] some large cracks and the door would not seal properly and built up with ice, so they've tried to rectify the problem by replacing the door or the weather stripping," she told CBC News.

"I'm tired of complaining, so we just live with the ice buildup," she added. "I think it's the quality of the door. Something is lacking, for sure."

April McKnight, whose house in Winnipeg's Arrowwood development had shingles coming off the roof, said her door was patched by Kensington Homes but it keeps cracking.

Expert notes rushed job

McKnight's next-door neighbour, whose house was also built by Kensington, told CBC News he has had water coming through his door.

The neighbour also had concerns about his windows, after spotting a sticker on one window that indicated it had an Energy Star energy efficiency rating for climates in southern Ontario and the lower mainland of British Columbia, not Manitoba.

Brian Sheridan, a Winnipeg window and door expert, inspected the windows and doors at Wajda's house and said the finishings seem to indicate a rushed job.

"I'm still feeling some air coming in and around here. That means the insulation coming into the wall, possibly foam, wasn't sealed perfectly on the inside," he said.

"Whoever did it was either in a terrible hurry or just isn't proud of his work."

Sheridan also found problems with Wajda's back door, namely the absence of an interlock, which means he could move the door backwards and forwards.

Company responds

In an email sent late Thursday, Kensington Homes says it does not rely on the Energy Star rating program for windows in its houses.

"The 'Energy Star' rating system for windows is not used by us and we are not aware of any other Manitoba home builders that use or promote 'Energy Star' when marketing homes," Tony Balaz, Kensington's Winnipeg manager, stated in the email.

"In its place regional programs such as Power Smart and R2000 as offered thru [sic] Manitoba Hydro have been promoted by us and other Manitoba home builders with good success."

Balaz said the sticker that McKnight's neighbour found on his window indicates that it's a triple-pane window, meaning it exceeds the minimum building code requirements and is acceptable under Manitoba Hydro's Power Smart Program.

"This tri-pane window will also meet or exceed the new energy code requirements when they are added to the national building code in the future," he said.

However, Manitoba Hydro's own website encourages people who want to upgrade their windows, doors or skylights to choose Energy Star-qualified products "that are appropriate for your climate zone as defined by Natural Resources Canada."
