Inspectors are noticing an increasing trend and many are starting to question the workmanship done on some condo developments and homes in Alberta.

The problem is condo rot which occurs when moisture gets into openings and behind finishes, like stucco, and rots the wood and insulation underneath.

"It will get in and if it doesn't have a chance to drain properly that's when you can end up with moisture creating rot and mold and mildew," says Senior Inspector, Darcy McGregor from Home-Alyze.

McGregor stresses the importance of checking your own home and says routine maintenance will help.

"If it's watched closely and looked after properly the chance of having ongoing problems is reduced, it still doesn't mean you won't have them," said McGregor.

The Canadian Condominium Institute says they are aware of the issue and believe poor workmanship may be to blame.

"I think it's really come to light over the last few years because all of the sudden we have a lot of condominiums that are reaching the age where were seeing that there has been problems created by these deficiencies," said Marc Bateman, President of the Canadian Condominium Institute, South Alberta Chapter.

Bateman says the government, builders and associations are working together to provide more protection for those left with massive repair bills and that there needs to be stricter regulations for building standards.

The Canadian Condominium Institute has recommended several legislation changes which include altering the home warranty program to allow more protection for the homeowner.
