Protecting Your Home: Understanding Placement of Downspouts

Schedule Now

Downspouts form a connection between the roof and the basement of your house. That connection is rainwater shed by the roof that infiltrates basement walls, causing a chronically wet basement. Water seepage into basements is a major problem that deteriorates basement structure and can make the interior basement space unusable for many purposes, as well as a source of mold contamination and other moisture-related issues. This is why placement of downspouts is so important.

One inch of rainfall on a 1,000 square foot roof equals over 600 gallons draining through gutters and into downspouts. Homeowners may expend large amounts of money and time on attempts to seal basement walls against water seepage. Often, proper placement of downspouts is a more cost-effective method that achieves better results simply by reducing the volume of roof runoff soaking into the ground.

Here are some guidelines for placement of downspouts:

  • As a general rule at least one downspout should be placed per every 40 linear feet of gutter. This ensures adequate drainage to prevent overflowing gutters during heavy rain. An overflowing gutter cascades onto the ground below, forcing water into the ground immediately adjacent to the foundation wall and exacerbating seepage into the basement.
  • Downspouts should not discharge where water may pool close to the house and foundation. Paving stones or walkways that aren’t properly pitched away from the exterior wall can act like dams that cause water to back up next to the structure and greatly increase the amount of ground seepage and infiltration into the basement.
  • If downspouts cannot be relocated to a position where water drains properly away from the house, downspout extensions should be installed. These should be long enough to move the discharge point of water a minimum of four feet away from the house.
  • Where neither of the above options is doable, a downspout should be placed where it can be connected to an underground pipe that routes water far from the house into the yard or into the municipal storm sewer (if local laws permit.)

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
