The gutters are useful to direct rainwater away from the building, in order to prevent the foundation from being flooded and moisture seeping through the walls. Its installation is not difficult, as long as the proper techniques, tools, and materials are used and the corresponding precautions are taken.

Currently, the gutters can be made of galvanized steel, aluminum, plastic, or PVC, the latter being the easiest to place and the ones that require less maintenance work. In any case, the installation techniques are similar for all three systems.

Before proceeding with the purchase of materials, it must be taken into account that the diameter of the gutter must be proportional to the covered surface of the building in which it is to be installed. Once you have the appropriate gutters, you must determine the location of the funnels or downspouts, preferably in the corners of the house, trying to match the sinks. At this point it should be considered a slope to the slopes of 2mm trough meters, and it should be tensioned thread between the ends of the roof imitating the course of the slope. Once the line is drawn following this inclination, the supports for the gutter are fixed using screws at a maximum distance of 60 to 90 centimeters, depending on the model to be installed and the manufacturer’s instructions.

After all the fasteners have been fixed, it is necessary to try to place the gutter and the different accessories (downspouts, corners, covers, etc.), in order to identify possible errors and to verify the insertion marks of the accessories, pointing them out. With a pencil and then cut them.

First, the part corresponding to the descent (funnel) is placed and then the gutter is inserted in the supports and on the rubber seal of the descent, assembling the pieces according to the fit lines. The rest of the gutter is then inserted into the supports, installing the joint according to the existing marks inside.

Once the entire duct system is mounted on the supports, the downspout and gutter covers are placed, securing the joints with silicone to prevent leaks.

The next step is the assembly of the tubes that will guide the water to the ground, first placing a 60 degree elbow pointing towards the house, connecting it to another that will guide the downspout next to the wall. This conduit must be fixed to the wall with the help of a clamp, and the final touch will be to place an elbow at the lower end of the downspout, to guide the water away from the facade or towards the nearest roof gutter drain
