HEPA air scrubbers remove contaminants from the air. This is an especially important piece of fire damage restoration equipment, as lingering soot particles can lead to health problems in a structure’s inhabitants after a fire. Commercial air scrubbers are also important in mold remediation when filtering mold spores from the contaminated environment. HEPA filtration ensures that even the smallest soot or mold particles are removed from the air.
The U.S. Navy has a similar approach when working on jet engines. Engines requiring repairs are not simply yanked from the air frame and disassembled without first creating, then discussing, the maintenance plan or objectives with the shop boss. This keeps things flowing smoothly in a hanger where there would always be several jets in various stages of repair. It was much the same as a mold shop where a group of repair technicians work on multiple molds during the day or week, sharing equipment, tools, and space.
A critical part of any mold maintenance plan is to provide the technicians a historical summary of past issues and corrective actions so they may be aware of longstanding or unresolved issues during repairs. Unfortunately, some technicians skip this first stage until after they get a mold disassembled—and then they stop to research a problem whenever they see or feel something they don’t like.

Position the drywall section in the opening, and use a helper to hold the new drywall in place. Install fasteners through the drywall into the wall or ceiling framing. You can use drywall nails or drywall screws. Screws are better because they cause much less damage to the internal structure of the drywall sheet during installation. Install fasteners every 9 inches on the perimeter, and every 12 inches in the field. If necessary, use a piece of plywood or one-by lumber for a backing and fastening surface behind any drywall edges that don't fall over framing.


All water damage restoration jobs are unique and the amount of work required for each depends on a variety of factors such as the amount of area in the home that’s been damaged and how long the water has been present. Once a professional water damage cleanup vendor arrives and has a chance to inspect the home, they’ll be able to put together a detailed project timeline specific to your job. In the meantime, we’ve listed the eight common phases that occur during the water damage restoration process and what happens in each, so you’ll know what to expect.
You can easily spot the most visible type of mold, called mildew, which begins as tiny, usually black spots but often grows into larger colonies. It’s the black stuff you see in the grout lines in your shower, on damp walls, and outdoors on the surfaces of deck boards and painted siding, especially in damp and shady areas. A mildewed surface is often difficult to distinguish from a dirty one. To test for mildew, simply dab a few drops of household bleach on the blackened area. If it lightens after one to two minutes, you have mildew. If the area remains dark, you probably have dirt.
Water damage occurs when excess water begins to pool in areas where it shouldn’t. Many different factors can create this excess water and thereby contribute to water damage. When you are aware of the potential causes, you can take precautionary measures to help insure against a leak or flood. You will also be able to spot a problem as soon as it arises and nip it in the bud before it has a chance to cause any additional damage. The more quickly you notice the problem, the less work the water extraction and >water damage restoration company will have to fix.
If temperatures tend to freeze in your area, be sure to protect your pipes. Insulate both hot and cold water pipes using heat tape or pipe sleeves available in your home improvement store. If you have water supply lines in your garage, keep the garage door closed as often as possible. Open kitchen and bathroom cabinet doors to allow warmer air to circulate. If you plan to spend some time away from your home, leave the heat on and set your thermostat to at least 55 degrees. You can’t control the weather, but you can put up a good fight to save your pipes.
For instance, if you remove 16 ejector pins from a mold and notice that a couple of them feel tight, will you remember which ones were tight later on, when you peruse past records to discover that galling pins have been a problem for the past five production runs? Knowing this information before you split or disassemble a mold removes some of the guesswork involved when looking for the root cause.
Homeowners insurance may help cover damage caused by leaking plumbing if the leak is sudden and accidental, such as if a washing machine supply hose suddenly breaks or a pipe bursts. However, homeowners insurance does not cover damage resulting from poor maintenance. So, if damage results after you fail to repair a leaky toilet, for example, homeowners insurance likely will not pay for repairs.

Today’s precision welding shops specializing in plastic injection mold, dies and tooling repair have a wide range of new technologies available to enhance their ability to provide the highest level of quality, craftsmanship, and service to their clients. One of the fastest growing technologies is the use of manual laser welding systems as an alternative to traditional microscope GTA welding.
Even a competent DIYer should have a qualified professional assess the damage first — making sure no part of the cleanup is missed. Before doing anything, check with your insurance company — they may require a licensed assessment. Don't wait. As soon as you detect any damage, call a professional. With time, each class and category quickly degrades into something worse.
“Last December we discovered a leak underneath our kitchen that caused extensive damage. We called WaterBear and they came out that day. The people who came to our house were always respectful, kind and efficient. They did exactly what they quoted us and did it in a timely manner. All of our questions and concerns were answered in a timely manner, also.   They helped us through this very difficult situation. I hope we never have another problem like this, but if we did, I would call WaterBear.” – Anne M.
During the walkthrough, compile a list of flooded equipment to help you estimate man-power requirements and create a preliminary schedule of repair work. As mobilization of crews begins, start developing job strategies, such as finding office space, living accommodations, and transportation for crews. You must also think about arranging food/catering services and developing work schedules. Once your crews have been mobilized and job-site safety requirements are met (see SIDEBAR: Developing a Safety Plan Following a Natural Disaster), it's time to go to work.
A flood-damaged car that has been totaled should have a “salvage” title, but some sellers use lax registration procedures in certain states to “launder” titles and eliminate the salvage branding. Buyers should also know that flood-damaged vehicles can be shipped anywhere for resale, and continue to appear in the marketplace for many months following major floods.
Throughout the drying process, crews will stop by periodically to monitor how the drying is progressing. Specifically, they monitor the dehumidifiers’ intake and output temperatures and humidity levels to make sure the dehumidifiers aren’t putting wet air out into the room. They’ll also go back and take readings of the same surfaces they did during the inspection phase. As rooms are declared dry, crews will often move equipment around to other areas of the home that are still wet.

Wanna keep things really cheap? Do it yourself! In some cases, minor mold problems (less than about 10 square feet of mold) in places like a bathroom corner can easily be handled by a handy homeowner with a free weekend afternoon and a few basic supplies from the hardware store. For more information, see our previous post on the subject: Do I need a Mold Remediation Professional?


Gradual damage is when something happens slowly over time and causes damage to your property. Gradual damage due to water damage is a common problem when it comes to insurance claims. An example of gradual damage is when something happens slowly, like paint chipping off a wall it starts with a small chip, then eventually half the wall is uncovered.
