John's Waterproofing Q&A

The power is out and my sump pump alarm won't shut off. What do I do?

If the alarm is going off that can mean one of two things. If you have a battery backup pump it is letting you know the battery backup is working. It will continue until the power comes back on. However, if you have a water watch alarm there is a button on the alarm that you can press for 3-5 seconds to silence the alarm for 24 hours.

How long will the battery backup last if the power goes out?

There is not a set amount of hours for the battery backup. The battery backup will pump 12,000 gallons of water on a single charge. How long the battery will last depends on how much water you have in your space.

Can I use my Crawl Space for storage?

It depends, if you have a vented crawlspace, then it is not advisable. A vented crawl space is open to the elements and has a high risk for mold, pests, and high humidity all of which can damage your stored items.

However, with our crawlspace encapsulation, you can have a controlled environment that can make the space usable for storage. Our full encapsulation will include a layer of TerraBlock, providing a layer of insulation over the dirt floor, also making it more comfortable to move around on. A CleanSpace vapor barrier is then secured over it, this is a 20 Mil woven barrier backed with a twenty-five-year warranty against tears and rips while keeping the water out. The foundation walls are insulated and air sealed, and every vent is sealed up. As a final piece, a SaniDry dehumidifier is installed to keep the humidity levels under control. All of these work together to make a crawlspace ready to be used for storage if wanted!

How to fix mold damage?

Mold is always a tricky one. The fix for mold depends on not only the type of mold but the source and the location. Surface mold can be cleaned with a variety of things including; bleach water, vinegar, hydrogen & peroxide, or baking soda. This, however, will only eliminate the surface mold you can see. In order to eliminate mold, you must reduce the relative humidity in the space. This can easily be done with a dehumidifier in the space.

How to get rid of black mold inside your home in Oregon?

The best way to get rid of black mold is to take away the things that make it grow. Mold needs a relative humidity of over 55% and organic substances to grow. Eliminating these items will eliminate it from growing. If the Mold is already present, we would recommend getting it professionally cleaned out by a mold remediation company.

How to get rid of mold in crawl space?

Mold needs two things to grow, organic material and moisture. By taking those things away, the mold will have no way to grow. Your indoor relative humidity levels should be between 30-50% to prevent mold growth. This is where our crawlspace encapsulation system comes in handy. With our product, Cleanspace, being made with a treated, non organic material it takes away the organic material factor that the mold needs to feed of off to live. To keep humidity levels down, we have our Sanidry dehumidifiers that will take moisture out of the air while filtering it, causing clean dry air to be pushed back into the crawlspace and eliminating the moisture factor that the mold needs to grow. For a further explanation call and set up an appointment for one of our inspectors to come out and they can give you a detailed presentation on how we accomplish this!

My power came back on but the pump is still not working, what do I do?

Often this can be due to a tripped GFI (think about the small button on your home plug-ins that sometimes flip if something too powerful is plugged in). This is a safety precaution to make sure you don't start a fire or blow the fuse. The sump pump may also have one of these GFI's depending on the type and model. This could be located on the sump pump or on the cord or outlet it is connected to. If resetting this GFI does not restore function to your system, please call our office so we can have one of our techs come and look at it.

If you already have one, your service technician will service it during the annual maintenance if you don't, your technician can install one for you.

What is the best Attic Insulation?

We highly recommend Cellulose Insulation. It is treated with a non-toxic borate solution that gives this material a Class-1 fire safety rating, the highest rating available. It also means that this will be both mold and pest resistant. Cellulose also offers a superior R-value compared to traditional fiberglass insulation. Cellulose is more durable, and won't compress, ensuring its effectiveness over time. Cellulose is also considered a "green" product. It is primarily made from recycled newspaper. The eco-friendly nature of the material combined with its energy efficiency makes it a great choice for homeowners who are concerned about the environment.

We highly recommend a 20 Mil thick vapor barrier; CleanSpace. This is made of a woven material and is backed by our twenty-five year warranty against rips and tears.

Where is the water in my crawlspace coming from?

This is probably the most frequently asked question we get from our customers. The truth is it can come into the crawlspace in various ways but it always starts from above... the rain. From there:

1: In heavy or long consistent rain, lawns can become saturated and so many customers believe the answer is doing exterior french drains. While french drains are good for slowing down water that is coming downhill, heavy rain spreads out beyond and under french drains. With the footing of a foundation anywhere from 3ft below the surface of the exterior dirt line and a french drain sitting typically 1-2' below ground level, this does little to stop the water.

2: Bad Rain Drains. A roof takes on an average of 623 gallons of water per sq ft during rainfall. You can imagine how much falls during a heavy downpour. So, if your downspouts are not sufficiently moving the rain well away from your property, that water will saturate the area around your foundation and flood your crawlspace. While a proper drainage system and sump pump can help, the best way to handle downspouts is to extend the downspouts under ground to a safe distance away from the foundation.

3: Water Tables. If you live in an area with high water tables, as they rise, so will the water in your crawlspace. If you have a stream or pond nearby you probably have high water tables but even without an obvious water source, some areas can suffer from an underground springs that will cause the same issue.

Where Should a Sump Pump be Installed?

Ideally a sump pump should be installed in the lowest point of your crawlspace or basement. This will allow the water to naturally grade down to this point so it will not pool. When a large amount of water is present or the area is generally level, we do then recommend a drainage system is installed to assist directing the water to the sump pump. From here the sump pump will divert and push all of the water safely out and away from the homes foundation.

Which is better, crawl space or slab?

There are pros and cons to each foundation type. Slab foundations are generally recommended for more wet climates and help reduce mold growth in the home and are less expensive for the most part. In addition, they tend to be more energy efficient as they don't have to be heated. On the flip side, they are more prone to cracking with shifting soil and can be damaged by tree roots. Crawlspaces work well for several applications. Sloped lots and areas prone to earthquake and ground shifting, they are better for drier climates as they are prone to moisture and mold growth. Wiring and ductwork are more accessible and can be used as a storage area if finished. They also have their own drawbacks. They are more expensive to construct than a slab, they take longer and are less energy efficient than a slab.

Who does foundation sealant Portland OR?

Depends on the type of sealant you are needing, different companies do different types of sealant. It is always best to do your research on your issue and the contractors, get multiple bids, search that they are certified contractors for that field and check out reviews online.

Why does my vapor barrier have mud on top of it?

If your crawlspace has a 6 Mil vapor barrier installed, then it should be changed out every few years. If your home experiences a large amount of water intrusion, then this will cause the 6 Mil barrier to be moved out of place. Once it is askew, water can begin to leak onto the vapor barrier, carrying mud and debris. Once water is stuck on top; mold and mildew can easily occur which can cause long-term damage to your home. If you find dirt or mud on top of your 6 Mil vapor barrier, give us a call, we can help.
