French Drains in Denver Metro

Keep Your Property Safe – Channel Water Away from Your Foundation

Drainage Options to Protect Your Home

While Colorado's front range typically has a dry climate, we do have a lot of snow melt and heavy spring and summer rainfall. French drains are an ideal solution to keep all this moisture away from your home, out of your basement, and safely direct it away from your property.

You’re probably on this page because you’re experiencing one or more of the following:
  • Water leaking into your basement or crawl space
  • Water is pooling up against your house after rainfall or snow melt
  • Your yard slopes inward and directs water towards your house
  • You have a sinkhole in the middle of your yard which creates a swampy, wet area
  • Downspouts are funneling water right next to your house – where it can find its way into your basement

Even if you didn’t have these problems when you moved in to your home, these problems can appear over time as soil settles and erosion occurs in your yard.

Drainage Systems to Protect Your Home

The four possible solutions for common drainage problems are explained below.

1. French Drain System

The french drain system is the most complex of the drainage solutions and does a great job to address the most serious drainage issues. It is the most reliable way to keep water out of your basement. This is the most common solution that we install for our Denver metro customers.
What is a French Drain?

A french drain involves installing a hidden drainage pipe at the low point between two slopes: the already existing slope of the yard towards your home, and the slope (that we build for you) from your house towards your yard. The french drain pipe slopes slightly in one direction towards an exit point so that water is safely channeled away from your home.

Steps involved in creating a French Drain
1) Create a Trench for the Drainage System a Good Distance Away from the Home
We dig a 15 inch deep trench in your yard. Typically this trench is located 3-4 feet away from your house. The trench will slope slightly down towards an exit point. The slope coming towards your house will terminate at this french drain. All water carried by the slope will be whisked away by the french drain to a safe exit point where it won’t damage property.
2) Install the French Drain Pipe

Pea gravel is laid down and a 4 inch diameter flex pipe perforated with holes is inserted into the trench. This pipe has a fabric “sock” around it. The holes allow water to come in, and the fabric “sock” prevents dirt and other materials from seeping into the french drain pipe and causing clogging issues. Since the pipe follows the gentle gradient of the trench, it will slope gradually downward towards the exit point. When water is in the pipe, gravity will drive that water  from the house towards a safe exit point where the water can’t do any damage.

3) Surround the Pipe and Bury it
The pipe is surrounded with pea gravel – with dirt on top of the pea gravel where it meets the surface of the yard. This allows you to grow grass on top of the french drain so that it blends in perfectly with your yard.
4) Build a Slope Next to Your Home
With the excess dirt from the trench, we build a slope against the house. This ensures that any water that collects near the home will work its way down to the french drain – which does a great job depositing the water safely away from your home and out of your basement.

2. Downspout Extension Solution

Downspouts collect a tremendous amount of water from your roof. The entire square footage of your roof is emptied into a few very small downspouts. The result is vast amounts of water being dumped into in a very small area.
If this water isn’t properly channeled away from your home, water can be directed towards your house causing foundation problems and basement flooding issues.
The Downspout Extension Solution

To properly deal with this issue, we will use a solid 3″ flex pipe. The flex pipe will be attached to your downspout buried under your yard. The exit to the pipe will be on your property where there is a positive slope away from your house. This will safely keep all the roof runoff away from your home.

3. Grading Only Solution

Grading as a Drainage Solution
Grading to Prevent Water Damage in a Back Yard (hover over "+" icons to learn more)
With grading, we move the soil into a slope so that the soil nearest your house is higher than the soil away from your house. This is a common technique we use for our Denver metro customers.
This ensures that water drains away from your house, rather than towards your house and onto your basement floor.

A grading solution is preferable when possible as this is the least expensive option. It works best for minor drainage issues.

4. Catch Drain Solution

If you’ve noticed a sinkhole / swampy area developing in your yard over time, this can be solved with a catch basin solution.
With this solution, a catch drain is put into your yard and water is drained away from your property. This solution allows your yard to properly drain and dry out so that you have the proper level of moisture. Your yard will transform from a swamp into an area that you can once again use and enjoy.

Which Drainage Systems Will Work Best for Me?

In many cases, a french drain would be the best method to divert water from your home and and prevent structural and property damage.

Other times, it isn’t necessary. A less expensive fix such as grading the land away from your home may be all that is required.

My promise to you is that I will actively work to find you the best solution to your drainage issue in keeping in mind cost and effectiveness. I have overruled french drain recommendations made by contractors when I thought a installing one would be overkill. I will find the best solution for you.

FAQ

Will my existing landscaping need to be removed / relocated to accommodate a french drain?

In some cases, yes, your existing landscaping may need to be removed or relocated. We have to make sure that the french drain is located a good distance away from the house, and that sometimes necessitates moving existing landscaping.

We can easily move rocks or wood chips, and it is possible to replant some items like shrubs. However, while we are french drain specialists, we are also a full service landscaping company. We will ensure that your french drain is functional and your yard looks great when we’re through.

Do I need more than 1 french drain?

Usually 1 french drain is required for each side of your yard that drains significantly inward towards your house. In extreme cases, you may need two or more drains in parallel. It is rare to need drainage systems in parallel, but it does become necessary in severe cases on long, steep slopes that collect a lot of rainfall.

Does a French Drain Require a Pump or Electricity?

No. The french drain uses gravity to gently steer water away from your house into an area where it won’t cause any problems.

Do I still need a sump pump with a French Drain?

 A sump pump isn’t required if you have a french drain. We still recommend a sump pump for most homes in Denver metro. The pump provides an additional level of protection to move water off your property.

Can I Do a DIY Drain System Install?
Probably not. At least not one that works as it is supposed to.
What About Pipeless French Drains?

Pipeless drains aren’t nearly as effective as a drainage system that uses an actual pipe as a conduit to move the water away from the house.  Without the pipe, gravity will have a much more difficult time moving water from your house.

Don’t Wait to Get a French Drain

(Updated 4/28/2020)
Colorado's Northern Front Range has a strong chance for a wetter than average stretch from May - July of 2020

The latest National Weather Service Outlook shows a good chance that it will be wetter than normal for May, June and July across Denver and Colorado’s northern front range.

Precipitation – especially towards late spring in Denver can come in the form of heavy snow, substantial fast snow melt, and heavy rain from thunderstorms.

If you were already experiencing drainage at times during 2019, you’d be wise to look at getting your property evaluated for a drainage solution before the wet weather poses a threat.
