When the Pipes Crack: Tips to Prevent Water Damage
When extreme temperatures strike, homeowners across the U.S. are crippled with millions of dollars in water damage to homes and buildings.
Leaving a home alone can become an expensive implication if things go astray while you are gone. And unfortunately more often than not, things do go wrong. Opportunely, there are certain things homeowners can do to protect their home and the interior possessions.
Water is the homeowners’ biggest enemy. If a pipe were to burst thousands of gallons of water can begin to flood the home. Bixler Corporation responds as an authority on pulling the pieces back together for home and business owners. When water damage results from cracked pipes, Bixler offers these tips for clean-up:
To Prevent Frozen Pipes:
- Wrap electrical heating tape on exterior pipes. Remove garden hoses from faucets.
- Cover pipes with foam rubber or fiberglass insulation and secure it with tape.
- Let cold and hot water faucets drip. Running water helps prevent freezing pipes and reduces pressure build up in them.
- Inside the home, open kitchen and bathroom cabinet doors to promote warm air circulation around plumbing.
- Leave the thermostat at the same temperature both day and night, at least 55°F.
To Thaw Frozen Pipes:
- Locate the problem pipe, if possible, and open a faucet. As the pipe thaws, running water aids the melting process.
- Apply heat to the frozen section using a hand-held hair dryer or portable electric space heater. Do not use a blow torch as it could cause the pipe to explode. Do not use a propane or kerosene heater as these are hazardous for indoor use.
- If you are unable to locate or access the frozen pipe area, call a licensed plumber.
- If all else fails and you experience a burst pipe that results in water damage, shut off the main water valve and contact us for water damage restoration services with trained technicians and extraction, drying and dehumidifying equipment.
If Water Damage Occurs, Tips for Clean-Up:
- Shut off the main water valve, if practical, and call a plumber to fix the leak.
- Call Bixler immediately for mitigation services, as required by your insurance policy. Certified Firms like Bixler have the knowledge, experience and equipment to locate water wherever it goes, remove the excess, and dry your structure to industry standards.
- Mop up standing water on flooring surfaces to prevent slip/fall hazards. If the burst pipe is overhead, drain ceiling cavities by punching “weep” holes.
- Prevent mold growth. Although it takes a few days to appear, mold thrives on wood, paper, particle board or even household soil, when stagnant air, moisture, and temperatures between 68 and 86 degrees are present.
- Wet clothing usually is salvageable. A 10-minute wash cycle in detergent and hot water should sanitize washable clothing and many household fabrics.
- Dry out before you rebuild. We have a variety of instruments to determine when a building is dry, to prevent on-going microbial growth. Drying should not stop until wood or drywall moisture content (MC) falls below 16% MC. Normal MC is around 10% in most areas of the country. [Source]
Storm Damage Restoration Recommendations
The following information is submitted by Bixler Corporation as a public service to those who have suffered water-related losses due to storm damage (e.g., hurricane, tornado). Since there are many variables involved in deciding about appropriate restoration steps, users of this information assume any and all liability for implementing the procedures covered herein.
The following recommendations assume water-related storm damage to residential or light commercial structures. For recommendations regarding restoration of major commercial properties and building assemblies, it is important to consult with professionals who have specific training and experience in this area.
Whether insured or not, it is important for property owners to document damage with photographs or video, and immediately, to begin loss mitigation procedures themselves; or hire a qualified contractor to do this on their behalf. It is totally inappropriate to put off mitigation while waiting for an insurance claims representative to arrive on the scene to evaluate the loss. By that time, in all probability sufficient time will have passed to grow and amplify microorganisms, which may not be covered by insurance. Loss mitigation is defined by insurance policies as “reasonable and prudent measures designed to preserve, protect and secure property from further damage,” including microbial growth and amplification.
According to The Clean Trust Standard and Reference Guide for Professional Water Damage Restoration (IICRC S500), there are three categories of water that cause damage in buildings. They are summarized as follows:
Category 1 Water – That which is clean at the releasing source and does not pose a hazard if consumed by humans. Category 1 water may become progressively contaminated as it mixes with soils on or within floor coverings or building assemblies (walls, decking, subflooring). Time and temperature, which promote the growth and amplification of microorganisms in water can cause Category 1 water to degrade. Examples: burst water pipes, failed supply lines on appliances, vertically falling rainwater.
Category 2 Water – That which begins with some degree of contamination and could cause sickness or discomfort if consumed by humans. As with Category 1 water, time and temperature can cause Category 2 water to become progressively more contaminated.
Category 3 Water – That which is highly contaminated and could cause death or serious illness if consumed by humans. Examples: sewage, rising flood water from rivers and streams, ground surface water flowing horizontally into homes. There are two ways in which water enters a building as a result of wind storm damage.
The first involves falling or windblown rainwater that enters as a result of damage to roof components or wall assemblies. The second involves horizontally traveling ground surface water (Category 3) containing silt and soil contaminants that infiltrate into structures, generally through doors or around foundation walls. This ground surface water (storm surge) may accumulate to a depth of several inches or several feet. When structures are partially submerged or remain substantially flooded for weeks, far more elaborate procedures usually are required.
Most household microorganisms (fungi, bacteria) typically require five conditions for germination, growth, amplification and dissemination. Generally, they include:
- organic food source, especially cellulose (e.g., paper, wood), which are found in abundance in construction materials
- moisture, even high humidity (67% RH plus)
- moderate temperature – 68-86°F/20-30°C
- stagnant air
- time – several hours to several days
Anything that can be done to control or minimize these optimum conditions will prolong the time required for microbial growth.
With the above background information in mind, loss mitigation procedures may include but are not necessarily limited to:
A. Foremost, consider safety:
- Structural Integrity – Before entering a storm or flood-damaged structure, consider structural integrity, which may be impacted by the force of the wind on, or the force of the water entering the structure. When in doubt, obtain an evaluation by a licensed and qualified builder or structural engineer before entering.
- Ventilation – Fresh moving air discourages the growth and amplification of microorganisms. Open windows and doors and air the structure out thoroughly. It is highly recommended that ventilation be maintained during and following the restoration effort, or until damp areas can be contained and subjected to mechanical dehumidification (HVAC or specialized equipment). This reduces, but does not eliminate, inhalation of microorganisms.
- Shock Hazards – Ensure that electrical shock hazards have been eliminated by turning off the supply of electricity (circuit breakers) to damaged areas. Anticipate that electricity may be restored suddenly without notice.
- Personal Protective Equipment – Wear protective clothing, boots with steel or fiberglass shanks, and a hard hat. Protect yourself from injury or exposure to microorganisms. Wear protective gloves before handling contaminated materials. Splash goggles are highly recommended to protect and prevent microorganism entry through the eyes. An organic vapor respirator (paint respirator) is highly recommended to prevent inhalation of most microorganisms or spores.
B. Remove quantities of debris (silt, vegetation, floating objects brought in by storm surge), if present, with shovels, rakes, etc. Carefully clean all tools with appropriate detergents after use.
C. Identify the source of water and extent of wetting:
- When wind-blown rain water enters a building, it is important to identify the route of entry and to trace its path, as possible, to identify all wet components (ceilings, walls, insulation, framing). Professional water restoration contractors, when available, have specialized water-detection equipment and may be available to assist in this determination.
- In rising water situations, typically there will be a visible water line on drywall or paneling. However, water may migrate or wick upward within the wall material itself or within insulation behind the wall.
D. Remove unsalvageable or wet materials:
- When wetting is caused by storm damage and comes from overhead or around openings in the building envelope, and especially when power has been interrupted in hot climates, it is important to remove wet components, as possible, to expose pockets of saturation to air circulation before microbial growth can occur.
- Begin at the point of water entry and trace the path of wetting, removing ceiling and wall components and insulation as you go.
- Although it may be possible for professionals with specialized equipment to dry carpet, pad and sub-flooring materials, when damage is wholesale in an area, seldom will qualified contractors be available to respond for this work. Therefore, it is normally prudent to remove saturated carpet and pad.
- It is highly recommended that solid or laminated wood flooring, or sheet vinyl be removed to expose pockets of saturation.
- In rising water situations (storm surge with contaminated ground water):
- Remove and dispose of drywall, paneling or other wall materials up to a point 15-24″ inches above the water line visible on the wall. If possible, stay within four feet of the floor to salvage as much wall material as possible, since drywall is usually installed horizontally in 4’x8’ or 4’x12’ panels.
- Remove and dispose of wet insulation materials exposed during wall removal. Look for evidence of moisture wicking up insulation materials. Leave only wall framing components that are durable and minimally porous, and which can be cleaned and decontaminated with relative ease.
- Remove and dispose of floor coverings; carpet, cushion, pad, felt and sheet vinyl, laminate, or tile flooring materials. Porous materials may absorb considerable quantities of water and contaminant, and non-porous materials may trap moisture to prolong drying. The inevitable result will be rapid microorganism growth, along with associated odor and health hazards. Hardwood flooring should be removed since contaminants and moisture will collect underneath in the flutes or hollow areas between the hardwood and the subfloor.
E. With Category 1 (clean source) water (e.g., rainwater), drying is the next course of action required to prevent on-going damage due to microbial development.
The following procedures may require the assistance of a professional water damage restoration company like Bixler, which has trained technicians, specialized cleaners, biocides, extraction, drying and dehumidifying equipment, and moisture measuring and monitoring instruments.
F. With ground surface water (Category 3), steps for cleaning soil residues brought in by heavy rainfall or storm surge may include, but are not limited to the following:
- Since many biocides are inactivated by quantities of organic contaminants, cleaning always should precede biocide application.
- When fresh water is restored within the structure, mix an appropriate general-purpose household cleaner according to label directions and liberally spray it onto salvable components.
- Brush agitation may be required to evenly distribute cleaning solutions, followed by at least ten minutes of “dwell time” for soil suspension.
- Where appropriate, flush contaminants from salvageable surfaces with a water hose or pressure washer. Work from top-to-bottom and from walls-to-flooring.
- Wet vacuum or mop up excess rinse water from flooring materials immediately. Be sure to thoroughly flush all contamination from wall frame (sill plate) areas. Pressure washing, if available, is specifically recommended to flush contaminants from hard-to-access areas, followed by removal of contaminated water with industrial wet vacuuming equipment.
- Repeat steps 6-9 as necessary, until all surfaces are clean and contamination is physically removed.
- Applying disinfectants or biocides usually is unnecessary with Category 1 (clean source) water, since this may only serve to introduce additional moisture into the building, which may prolong drying.
- With Category 2 or 3 water contamination, while maintaining ventilation and skin and respiratory protection, liberally spray cleaned salvageable materials (studs, decking, joists, etc.) with an appropriate biocide. A 6% solution of household chlorine bleach (e.g., Clorox®) mixed 1 part bleach to 11 parts water (1⁄2%) may be used on durable, colorfast surfaces. Never mix chlorine bleach with ammonia or strong acids! An appropriate alternative to chlorine bleach may be a 3% solution of hydrogen peroxide.
- In rising water situations, following application of properly diluted biocides, brush agitate all areas to encourage biocide distribution and penetration into cracks and crevices.
H. Dry structural components with plenty of air circulation, while maintaining constant ventilation (weather conditions permitting). If possible, take advantage of low outside humidity (check local weather reports). Use oscillating or box fans, repositioning them within the structure every few hours. Avoid temperature extremes that might slow drying, or promote microorganism growth (around 72-75oF/22-24oC is ideal). Rent high-volume professional drying equipment (airmovers and dehumidifiers) if available, especially in areas where ventilation is not possible (sealed buildings, security problems). It is highly recommended that electrical components that were wet be checked for operational safety by a qualified contractor.
I. Leave cleaned structural surfaces exposed to fresh air movement for several days or even weeks, or until you are sure that they have returned to within four percentage points of normal moisture content (MC) levels (generally the normal MC of structural wood is around 10%). Otherwise, subsequent structural damage and/or health effects may result after wall and flooring materials have been replaced or painted. Professional water restoration contractors with specialized, high-capacity drying equipment can shorten drying times considerably.
J. Reconstruct or replace components as required.
Consider hiring a professional restorer to evaluate moisture levels in structural materials before reconstruction. [Source]
