Gutter systems are important in preserving the foundation of your home. Downspouts and gutters divert water away from the house when it rains, which prevents moisture from corroding the foundation. Luckily, removing and installing gutters is a fairly easy process, and doing it yourself can save you a lot of money. Here is a quick guide on how to install new gutters on your home.

Step 1 - Take Measurements

Before removing the old gutters, measure the lengths of the gutters and downspouts for future reference. This will tell you how much length you need for the new pieces and how many downspouts you need to purchase. Then mark where the gutters are hanging on all corners of the house and note where the downspouts are located.

Step 2 - Remove Old Gutters

Start by removing the screws holding the downspouts in place. Once the downspouts are free, repeat the process with the gutter pieces. Keep safety in mind when removing the old gutters and use a helper when needed. If possible, do not allow the gutter to fall to the ground because this can create an unsafe work environment.

Step 3 - Mark New Gutters

When the old gutters are removed, you need to mark the slope for the new gutters. Using a ladder, snap a chalk line between the corners where you marked the old gutter locations. You only need a slight slope to drain water. Repeat this process around the perimeter of the roof until all the gutter locations are adequately marked.

Step 4 - Measure and Cut

Cut the new gutter pieces using the measurements you took in step one. You can cut the pieces with a hacksaw or tin snips. Once all of the pieces have been cut, measure a hole for each outlet plug. The outlet connects the downspout with the gutter and should be attached via screws or rivets, depending on the manufacturer. Waterproof each joint and screw holes with caulk or silicone glue. Lastly, install end caps wherever needed and caulk to seal the gutters.

Step 5 - Install Gutter Hangers

The gutter hangers should be spaced about every 2 feet or less for proper support. The key to installing the hangers correctly is to screw them into the rafter boards, not just the front fascia. If you do not screw the hangers into the rafters, you run the risk of the gutter falling when it is filled with water. Once the hangers are in place, you can install the gutters and attach them to the hangers via screws.

Step 6 - Attach Downspouts

With the gutters in place, the last step is to attach all of the downspouts. The downspout connects to the gutter via the outlet joint. Once the pieces are securely screwed together, seal all of the joints with caulk or silicone glue. Repeat this process for all of the downspouts, making sure they are draining away from the house.

By following these steps, you can install gutters in no time. Once they are installed, make sure to clean them regularly.
