Insulation & Drywall

Drywall

Doors are subject to some variations and warping. Seasonal conditions may cause the door to undergo a change in size, wider in summer and rainy seasons, narrower in dry winter conditions. Therefore, do not adjust or cut your interior doors, as it will tend to correct themselves. Variations of six millimeters (1/4 inch) or less out of plumb are considered normal for our climate.Report all adjustments and planning problems to your new home builder on the 12-month Customer Service Report.

Settlement

The wall studs and floor joists may twist slightly through the drying out process. Minor settlement is acceptable in the building industry. Please notify our Head Office in writing where the problem is excessive.

Humidity & Condensation

Excess Humidity

Excessive levels of humidity in the home cause condensation on windows. This encourages mold to form on plaster, cupboards to smell musty, rooms to feel damp, and condensation to form on cold water pipes, causing water to drip onto the floor or collect within a wall or ceiling.

Condensation can develop on windows if curtains or blinds are left closed, or if the furniture is covering heat registers located near the window.

The term ‘tight house syndrome’ refers to homes that are developed to avoid all heat loss. As a result, humidity builds up, particularly in rooms with poor ventilation.

Tips to provide better ventilation:

  • Let in the fresh air on fair days
  • Your furnace may have a humidifier, set it back or turn it off
  • Run exhaust fans in the kitchen and bathrooms
  • Ensure the clothes dryer is vented to the outside
  • Do not hang clothes to dry indoors
  • Your house plants should be kept in a well-ventilated room
  • The amount of humidity a household produces varies according to the number of occupants, amount and kind of cooking done, the number of baths taken, plants, etc., therefore, you cannot compare one house to another.

Ventilation is the only practical way to reduce the humidity unless you want to change your living habits. (A dehumidifier doesn’t get the humidity low enough to do the job in winter.)

To stop the condensation you must restore some of the lost ventilation. Keep at least one exhaust fan running as long as the windows are steaming up. It may be necessary to open one of the windows. We suggest using a basement window close to the furnace; to be sure it is getting all the combustion air it needs. (From The Toronto Star)

Normal Day to Day Condensation Control

Common causes of Water vapor:

  • Cooking
  • Showers
  • Drying clothes indoors
  • Unvented dryers
  • The washing cycle

Solutions to condensation:

  • The kitchen fan or window should be large enough to remove water vapor
  • Close the bathroom door when showing with the fan on or window open
  • When doing laundry, open a window in the laundry room
  • Cover your crawl space in plastic sheeting or other waterproof membrane
  • Keep all rooms, even if unoccupied, heated to a minimum of 10 degrees Celsius (50 degrees Fahrenheit)
  • Open windows for a brief period (10 minutes) to ventilate the house each day
  • Leave the damper open in the fireplace to increase ventilation and assist the rate of air change

Supplemental Fans

Your new home builder has put a fan in each bathroom (main bath fan also switched at thermostat location) for additional ventilation. These fans should be used to control local moisture and odours. Operating the fan for up to 30 minutes should control humidity from a shower or bath.

Range Hood

Check that the exhaust openings outside the house are not broken or blocked. Regularly scrub kitchen grease filters with hot, soapy water. Some exhaust fans need to be oiled and cleaned according to the manufacturer’s instructions.
