Hi Renovating your bathroom is a great way to add value to your home - both for your family's daily living and for future resale.
Before you decide to go ahead with a renovation, it's critical to have a good idea of any underlying problems that could cause unwelcome and costly surprises. Taking time to find problems before you start your renovation will save you money, protect the indoor air quality and preserve the durability and structure of your home. Renovating Your Bathroom Common Situations A bathroom renovation is one of the most common home improvement projects. Bathroom renovations come in all types and sizes-from a simple update of the flooring, to enlarging the room and replacing all fixtures and finishes. Your project is unique, but your reasons for renovating will probably fall into these common categories. . Size and design - The room may be small or poorly designed. . Fixtures - The fixtures may be outdated, small, hard-to-clean, leaky, cracked or inefficient. . Structural - There may be problems that require structural changes or repairs. . Moisture - Excessive bathroom moisture may have deteriorated the bathroom surfaces, affected the indoor air quality or jeopardized the structure of your house. . Plumbing and electrical - If your house is 30-40 years old, the plumbing and electrical services may be outdated and need upgrading. Houses built prior to 1950 often have lead piping that may pose a health hazard. . Heating and ventilation - Bathrooms are often cold because of poor insulation or poor heat delivery. Ventilation is often inadequate, non-existent or causing secondary problems that need to be fixed. Healthy Housing Renovating is an ideal time to make your house healthier for you, the community and the environment. When assessing your renovation project, be sure to consider the five essentials of Healthy Housing. House as a System A house is much more than just four walls and a roof-it's an interactive system made up of many components including the basic structure, heating, ventilating and air conditioning (HVAC) equipment, the external environment; and the occupants. Each component influences the performance of the entire system. A renovation provides an opportunity to improve how your house performs. Bathroom renovations often include changes to HVAC equipment that can improve moisture management in the house. Structural changes may improve air sealing and insulation, resulting in increased occupant comfort and house durability. Avoid Surprises Before you start renovating, you'll want to think about your bathroom, your needs and your budget. Look carefully for signs of deterioration and the possible causes. This will save you money and also help you to be better informed if you're dealing with contractors. Reflecting on your project will also help you to decide whether you need the services of a professional. Being unsure of what needs to be done, recognizing that the job is very complicated, or that you don't have the time or energy to do the work, are good reasons to hire a professional renovator.

Does the bathroom meet the needs of everyone in the household, including anyone with special needs, extended family and guests? Consider your options... .

Compact fluorescent light fixtures are four times more efficient than standard incandescent bulbs. . Cold toilet tanks are prone to condensation that leads to moisture problems. list end Structural Ask yourself ... . Which walls are load bearing? Will they need to be cut or removed as part of the renovation? . Are there any cracks, slopes or bulges that might mean that the floors or supporting members are deteriorating or inadequate? . Are the walls deep and strong enough to allow installation of grab bars, new windows, plumbing or ducts? . Are exterior walls, floors or ceilings cold or drafty?

The proposed renovation must either fit the existing structure or the required structural changes must be possible. Expert help may be needed. . Repair or upgrade structural elements so that they are able to meet expected loads. . Install structural blocking or backing as needed for grab bar installations. Build out walls to accommodate new windows, plumbing or ducts. . Insulate and air seal the exterior wall, ceiling or floor assemblies to provide warm surfaces and a draft-free space. ... and if you don't . Improper structural changes, new loads or proceeding with changes that stress the structure may cause wall settling or collapse. . Ignoring the underlying cause of bulges, slopes or cracks can result in recurring problems. . Installing structural blocking for grab bars after renovations are complete will cause expense and disruption. Insufficient wall cavities may limit or prevent installation of windows, plumbing or proper ducts. . Poorly insulated exterior surfaces, poor quality windows or poor air sealing will result in cold surfaces that cause discomfort and are prone to condensation, which can lead to mold growth. Moisture Ask yourself ... . Are any finishes moisture damaged? . Are there water stains or visible mold growth on any surfaces? . Is there any blistering or peeling paint? . Are any surfaces buckled, swollen or rotten? . Is there any chipped or cracked grout or caulking? Consider your options... .

Repair or replace all water damaged or deteriorating elements. . Clean up visible mold growth following CMHC guidelines. . Ventilate to control excess humidity. . Maintain grout and caulking to prevent water access to cavities. . Choose low-odour, low-toxicity materials and finishes to minimize the effects on indoor air quality (IAQ). ... and if you don't . Unresolved water problems will cause renovations to deteriorate quickly, whether the water comes from building leaks, plumbing leaks or the high humidity generated by bathroom activities. Leaks may contribute to mold growth and result in serious IAQ problems. . Hiding moisture damage behind new finishes can cause deterioration and mold growth to continue. table end Plumbing and electrical Ask yourself ... .

Have an electrician inspect the electric service and wiring. Repair and upgrade electrical service and wiring if needed. Equip outlets with ground fault circuit interrupters for safety. . Update lighting so that it is adequate and energy efficient. ... and if you don't . If plumbing problems aren't repaired, deterioration will continue and mold will grow. . Poor water pressure and water hammer problems will continue. . Plumbing problems such as slow drains or smells from poor venting will still be annoying, may get worse and be a source of poor IAQ. . Lead piping and corroded metals can contaminate water and leak. . Electrical service, wiring and outlets may be inadequate or unsafe for increased loads (e.g., whirlpool tubs or space heating). New lights or outlets may overload existing wiring. . Lighting may be poor and use energy inefficiently. Heating and ventilation Ask yourself ... . Is the bathroom cold? . Does condensation form on windows, mirrors or other surfaces? . Is there a stale, musty smell? . Is there an exhaust fan that doesn't work? Does the fan vent directly to the outside? Is the duct insulated where it passes through unheated spaces? Consider your options... . Provide an adequate heat source. . Ideally, install a whole house ventilation system, including a heat recovery ventilator. . If the whole house system is not an option, install a quiet exhaust fan with adequate airflow capacity to handle excess humidity. The fan should have a sound rating of two sones or lower and must vent properly to the outside. ... and if you don't . Problems can arise if heating, ventilating or air conditioning (HVAC) needs cannot be met by the capacity of the services available. The heating supply must be enough for comfort.
