How it works
Assess the drainage path
We look at the grade around the downspout to determine where water needs to go and how long the extension should be.
Fit & connect
We connect the extension to the downspout with the right elbow angle and secure it so it won't shift during heavy rain.
Test & adjust
We pour water down the system to confirm flow and adjust the angle or length if needed.

Good to know
Downspout Extension Install in Charleston — FAQ
How far should an extension direct water away from the house?
A minimum of four to six feet from the foundation is the general guideline, and farther is better if the grade slopes back toward the house.
What materials are extensions made from?
The most common options are matching aluminum to blend with existing gutters, or flexible corrugated plastic that can snake around landscaping features.
Can I get an extension that folds up when not in use?
Yes — hinged flip-up extensions are available that lie flat when dry and extend when rain pushes water through. They're convenient for areas where you mow close to the house.
Do I need an extension on every downspout?
Primarily the ones closest to basement windows, doors, and foundation walls. We can assess each one and prioritize based on where drainage is actually causing problems.
Local context
Downspout Extension Install across Charleston
Charleston's humid subtropical climate, salt air and active storm season are tough on homes — swollen doors, rusting hardware, mildew-prone caulk and storm-loosened trim are all common. Downtown's historic houses add original plaster walls and tight, detailed millwork, while West Ashley and the islands bring newer builds with their own quirks. Our pros are comfortable with both.
