Installing downspouts is a crucial task for maintaining the structural integrity of your home. They effectively channel rainwater away from the foundation, preventing water damage and other costly problems. If you’re looking for a cost-effective way to improve your home’s drainage system, installing downspouts is a great option. Here’s a comprehensive guide to help you get started on this do-it-yourself project and protect your home from water damage this season.
Before embarking on the downspout installation process, it’s essential to gather the necessary tools and materials. You’ll require a ladder, tape measure, level, saw, drill, gutter sealant, screws or nails, and downspout elbows and extensions. Ensure you have all the materials on hand to avoid any delays or interruptions during the project. Once you’ve collected the necessary tools and materials, it’s time to prepare the downspout location. Carefully inspect the eaves of your home and determine the ideal placement for the downspouts. Ensure they’re positioned directly above the gutters and extend far enough from the foundation to prevent water damage.
With the downspout location determined, it’s time to cut the downspouts to the appropriate lengths. Measure the distance from the gutters to the ground, factoring in any necessary elbows and extensions. Use a saw to cut the downspouts to the desired lengths. Once the downspouts are cut, assemble the downspout system by connecting the elbows and extensions. Make sure the joints are secure and apply gutter sealant to prevent water leakage. Finally, attach the downspouts to the gutters using screws or nails. Ensure the downspouts are positioned straight and securely fastened to prevent any sagging or detachment. With the downspouts installed, you can now enjoy the peace of mind knowing that your home is protected from water damage.
Measuring and Cutting Downspouts
Once you have determined the location and length of the downspout, you can measure and cut it to fit. Here are the steps:
Measure the length of the downspout
Use a measuring tape to measure the distance from the top of the gutter to the ground. Add 1 foot to this measurement to allow for cutting errors and to ensure that the downspout extends at least 6 inches below the ground level.
Cut the downspout
Mark the length of the downspout on the downspout material using a marking pen. Use a hacksaw to cut the downspout at the marked length. Be sure to wear gloves and safety glasses when cutting metal.
Creating a Clean Cut
To ensure a clean cut on the downspout, follow these tips:
| Step | Action |
|---|---|
| 1 | Use a sharp hacksaw blade. A dull blade will tear the metal and produce a rough cut. |
| 2 | Apply steady pressure when cutting. Don’t force the saw through the metal, as this can also cause tearing. |
| 3 | Support the downspout securely. Hold the downspout in a vise or use a saw horse to prevent it from moving while cutting. |
Installing Downspout Brackets
1. Determine the Placement of the Brackets
Identify the optimal locations for the brackets along the downspout pipe. They should be spaced evenly, typically every 2 to 3 feet, to provide adequate support and prevent sagging.
2. Mark the Bracket Positions
Use a level to ensure that the downspout is vertical and straight. Mark the positions of the brackets onto the wall or fascia board using a pencil or chalk.
3. Drill Pilot Holes
At each marked position, drill small pilot holes using a drill bit slightly smaller than the bracket mounting screws. This will help prevent splitting the wood when installing the screws.
4. Install the Brackets
Position the brackets over the pilot holes and drive the mounting screws through the holes and into the wood. Use a screwdriver or drill with a screw bit to tighten the screws securely. Ensure that the brackets are firmly attached and that the downspout is properly supported.
a) Types of Brackets
There are various types of downspout brackets available, such as:
| Type | Description |
|---|---|
| Slip-on | Slides over the downspout and is secured with screws |
| Strap | Wraps around the downspout and is fastened with screws or nails |
| Concealed | Hidden behind the downspout and is attached with screws through slots in the pipe |
b) Material Considerations
Choose brackets made of corrosion-resistant materials such as galvanized steel, aluminum, or vinyl to ensure durability and withstand outdoor elements.
c) Sizing the Brackets
Select brackets that are appropriately sized for the diameter of the downspout pipe. The brackets should fit snugly around the pipe to provide optimal support.
Connecting Downspout Sections
To connect downspout sections, follow these steps:
- Clean the ends of the downspout sections to remove any dirt or debris.
- Apply a bead of silicone sealant to the inside of the upper downspout section.
- Insert the lower downspout section into the upper section, aligning the crimped ends.
- Use a pair of slip-joint pliers to tighten the crimped ends together.
- Apply a generous amount of sealant around the exterior joint of the downspout sections. Use a putty knife or your finger to smooth out the sealant and create a watertight seal.
To ensure a secure and watertight connection, consider adding a downspout coupler. Downspout couplers are metal or plastic fittings that fit over the joint and provide additional support and stability.
| Downspout Size | Coupler Length |
|---|---|
| 2″ x 3″ | 4″ |
| 3″ x 4″ | 6″ |
| 4″ x 5″ | 8″ |
To install a downspout coupler, simply slide it over the joint and tighten the screws or bolts. Downspout couplers are especially useful for connecting different sizes of downspouts or for repairing damaged sections.
Attaching Downspout to Gutter
Once the gutter is in place, you need to connect the downspout to collect the rainwater and divert it away from your home’s foundation. Here’s a detailed guide on how to attach a downspout to a gutter:
1. Measure and Cut Downspout Length
Measure the distance from the bottom of the gutter to the ground or splash block. Add a few inches for cutting and fitting. Cut the downspout to the measured length.
2. Attach Downspout Hanger to Fascia
Hang downspout hangers from the fascia, which is the vertical board at the bottom of the roof. Space the hangers every 2-3 feet for proper support.
3. Slide Downspout into Hangers
Insert the top of the downspout into the hanger closest to the gutter. Slide the downspout down, engaging it with the remaining hangers.
4. Mark and Cut Gutter Outlet Hole
Align the top of the downspout with the gutter outlet location. Mark the gutter where the downspout will connect. Use a hole saw to cut a hole slightly larger than the downspout diameter.
5. Remove Excess Gutter Material
Trim away any excess gutter material around the hole using aviation snips or metal shears.
6. Attach Downspout to Gutter
There are several methods to attach the downspout to the gutter:
| Method | Materials | Steps |
|---|---|---|
| Downspout Elbow | Downspout elbow | Attach the elbow to the gutter outlet hole. Slide the downspout into the elbow. |
| Gutter Connector | Gutter connector | Place the connector over the gutter outlet hole. Insert the downspout into the connector. |
| Screw or Rivet | Screws or rivets | Align the downspout with the gutter outlet hole. Use self-drilling screws or rivets to secure the downspout to the gutter. |
7. Secure Downspout to Wall
Use downspout brackets to secure the downspout to the exterior wall every 4-5 feet. Drive screws through the brackets into the wall studs.
Redirecting Downspout Water
1. Choose a Discharge Location
Select an area where water can be safely drained, such as a garden, lawn, or storm drain. Consider the slope and elevation of the area to ensure proper water flow.
2. Determine the Drainage Path
Create a drainage path from the downspout to the discharge location using bury pipe or surface channels. Ensure a gradual slope for adequate water flow and prevent pooling.
3. Install Drainpipe
Dig a trench along the drainage path and install a drainpipe. Use a perforated pipe to allow water to escape and connect it to the downspout using a downspout adapter.
4. Secure Drainpipe
Cover the drainpipe with gravel or landscape fabric to prevent clogging. Secure the pipe with stakes or straps to ensure stability.
5. Direct Water to Discharge Area
Extend the drainpipe to the discharge location and use an elbow or T-joint to direct water appropriately. Reinforce the connection points with sealant.
6. Install a Splash Block
Place a splash block at the end of the drainpipe to prevent erosion and direct water away from the building foundation.
7. Consider a Rain Barrel
Capture rainwater for reuse by installing a rain barrel. Connect a downspout diverter to the downspout and direct water into the barrel. Use a hose or spigot to access the stored water for gardening or other purposes.
| Rain Barrel Capacity | Approximate Collection Area |
|---|---|
| 50 gallons | 500 square feet |
| 100 gallons | 1000 square feet |
| 200 gallons | 2000 square feet |
Sealing Downspout Joints
To ensure a watertight seal between downspout sections, follow these steps:
- Clean the joint surfaces with a wire brush to remove any dirt or debris.
- Apply a bead of exterior-grade silicone sealant to one edge of the joint.
- Press the two sections together, ensuring that the silicone sealant is evenly distributed.
- Hold the sections together for a few minutes until the silicone sealant begins to cure.
- Wipe away any excess sealant with a damp cloth.
Using a Downspout Connector
For a more secure seal, consider using a downspout connector, which provides additional support and prevents the joints from separating:
| Pros | Cons | |
|---|---|---|
| Threaded |
|
|
| Snap-on |
|
