Spring Water Problems

It’s time to start getting your home ready for spring.

Part 1:  Wet basements are the biggest problem. 

Most basement water problems are caused by exterior landscaping and hardscaping.  As a MN home inspector for the past 27 years, I have found this condition is seldom repaired until it becomes a problem.  What I mean is until a homeowner sees water they assume nothing is wrong.  This is not true.  Actually, small amounts of basement moisture can be more destructive than large water events, such as flooding.  Why, because as water sits on the walls it deteriorates the concrete, fungal growth begins to take hold, and a force, hydrostatic pressure, begins to push the foundation in.  The longer these conditions exist the more apt they are to develop into something substantial.

When I inspect a home for a client, I always ask them, at the beginning of the inspection, what type of concerns they may have in purchasing this home.  Almost always in the top 3 is that they do not want moisture in the basement.  After inspecting over 19,000 homes, I would estimate over 85% have some sign of moisture in the basement.  That is such a high percentage, that prior to inspecting the basement, I can almost answer their initial concern.  Yes, this home has basement dampness.

9 out of 10 times the cause of a wet basement is poor slope around the foundation.  Typically, this is corrected by raising the grade and hard surfaces so they slope away from the basement.  It’s so simple.

This spring it may be a good time for you to check the slope around your house…before it’s a problem.

9 Steps for Solving Unseasonably Wet Basements

What can a homeowner or real estate agent do NOW to better protect their homes against moisture intrusion?

This question is coming up all of the time this year. 2013 is a little unique and if the home that you have owned for years, or have just purchased, has moisture in the basement; you may just be experiencing the strange end to the past winter. We have had lots of rain and freeze thaw conditions that have overcome basement protection in many MN homes. You are likely discovering that basement protection that has worked for many years has simply been overwhelmed by seasonal conditions.

Homeowners, follow these 9 Steps to prevent a repeat of this year’s conditions causing moisture problems in the lower level of your home.

  1. Clean out and cover, window wells
  2. Fill all low spots along the side of your foundation
  3. Grade the soil away from the exterior wall, to an angle of 6 inches fall, in the first 10 feet from the foundation. If you don’t have 10 feet from the foundation to an obstruction or the boundary line; create a swale. Swales will be described in the very next blog.
  4. Clean out and replace or repair any damage to gutters
  5. Make sure gutter downspouts extend at least 6 feet away from the foundation
  6. Verify the neighbors’ gutter extensions are not directed towards your house
  7. Test the sump pump
  8. Make sure the sump pump exterior discharge pipe extends at least 10 feet away from the foundation (not into the laundry tub or floor drain)
  9. Have a battery backup sump pump installed

 

MN real estate agents, when contracting a home inspector in the future; be certain that you have employed someone who is on top of their game and very knowledgeable about grading, drainage, and sumps. Fail to employ a knowledgeable and diligent inspector and you may pay the price in a year like 2013.

When buying or selling a home, it is important to use the services of the best MN home inspector that you can find. Do your due diligence, and be certain that you are employing somebody who doesn’t miss the details. Ask yourself…

Can this inspector find the elusive signs of occasional water problems as well as all the other issues found in today’s homes?

Moisture Problems – Is Your Drain Tile Dependable (Part 12)

Too many homebuyers have hired MN home inspectors that found the sellers disclosure regarding basement moisture to be incorrect and sometimes blatantly false. Unfortunately, too often, unsuspecting real estate agents are pulled into this scheme. The biggest culprits of this ruse are sump pumps and drain tiles. You would be surprised how many innocent agents are told the basement of the house they listed is drain tiled…and never look to verify that it is true. This is way too risky and this home inspector intends for that never to happen to you. Honestly and understandably, many agents and homeowners have never been trained to be able to distinguish between the different types of water control systems.

Did You Remember?
Some systems work and many do not.

Recently, one of my home inspection students told a horror story in class about a lawsuit his daughter won against the real estate agents involved in her home purchase. The MLS listing stated that the house was drain tiled and the buyer’s agent when seeing the sump basket verbally confirmed that to be true. The daughter moved into the house and the basement flooded shortly thereafter. She was eventually awarded a $30,000 claim against both agents.

Did You Know?
Water always goes to the easiest exit point.

Drain tiled basements have a pipe that is continuous around the entire perimeter of the foundation. This 4” pipe has holes that will freely gather ground water before it gets onto the floor. These pipes extend and dump water into the basket which is then pumped outside.

So take the cover off the sump basket and look inside. If you see two 4” pipes coming thru the side of the basket, the basement is drain tiled and dependable. If there are no pipes, the basement is not drain tiled and undependable.

Very often what looks like a drain tiled basement turns out to be nothing but a pit in the floor. This would be a mega real estate agent or homebuyer nightmare.

Oh the sweet sound of the house speaking so softly.

Moisture Problems – Gutters (Part 6)

Large volumes of water discharge off a home’s roof and can compound a basement or crawl space moisture problem. Depending on the roof design, the amount of water can often be too much for even a yard that is properly graded away from the house. Sometimes we need to add gutters and downspouts to the roof eaves. However, all roofs do not need gutters, in fact, most do not.

DID YOU KNOW?
Building code does not require a house to have gutters

Controlling roof drainage is important, but it is never a substitute for proper grading. Too often frustrated homeowners look for the quickest and easiest fix to a basement moisture problem. When landscaping and hardscaping is too difficult or too expensive they look for a short cut. The easy answer is to install gutters, but roof drainage is always secondary to correct earth grading. So, if the landscaping and hardscaping are positively sloped away from the house and the foundation is still damp or wet then adding gutters to the roof is essential. Gutters will manage the surface water coming off the roof and, if properly installed, harmlessly drain it away from the foundation.

So how would a homeowner or real estate agent know when a home should have gutters?

The design of the house is the most common indicator. Homes that most often need to control roof drainage to stay dry have any one or all of the following characteristics:

• Steep roof pitch
• Roofs with valleys
• No overhangs or small roof overhangs

These house styles dump huge amounts of water directly on the foundation which, depending on the type of soil, will saturate the earth adjacent to the walls. These wet soils will hold moisture on or adjacent to the foundation which will eventually migrate towards and run down alongside the basement or crawl space walls. Gutters with the proper extensions will direct this water away from the house.

Understanding that all homes do not need gutters to stay dry…then what could be worse than a roof that needs gutters and doesn’t have any? How about a roof that has gutters with no or short downspout extensions…why?

Moisture Problems – Hardscaping (Part 5)

Although landscaping is so very important to a dry basement, sometimes other things outside the home can cause water to work its way inside. Because of difficulty and cost, people are often hesitant to consider the negative impact hardscaping can have on moisture intrusion. What I’m talking about here are:

  • Walks
  • Steps
  • Patios
  • Decks
  • Driveways

Just like the earth, over time these wood, asphalt, and concrete surfaces can settle. Often the settlement will either puddle water alongside or actually drive water towards the foundation. As I said these hard surfaces can be expensive to remove and replace. For this reason, most of the time, homeowners will leave the settled hardscaping and try anything and everything else to try to correct the problem…and it never works! There is a core principal here and that is, if water is being driven towards the foundation, at some time, it is bound to come into the basement. It might not be in normal rain or snow thaw, but during in-climate conditions it will.

That’s why if you ask a homeowner selling their house if they have moisture in the basement, their immediate reaction will be no. Then when they think about it for a moment, they will say something like well maybe a little bit on real heavy rainfalls or only when the downspouts are disconnected or only when it rains really hard from the north. What they are saying is the landscape and hardscape are not sloped adequately to handle large volumes of water. Homeowners, home buyers, and real estate professionals don’t expect basements or crawl spaces to be dry some of the time or even most of the time. Today, these people demand that these below grade spaces be dry ALL of the time.

So the grounds surrounding the home are very important to protect against moisture intrusion…but that’s just the beginning!
