Exterior Chimney Makeover: Upgrade a Plain Chimney Without a Full Remodel
Hi, I’m Brian, and I worked with this homeowner on a project to upgrade their exterior chimney.
The chimney was structurally sound, but it stood out for the wrong reasons. The plain siding made it feel unfinished and out of place compared to the rest of the home.
They wanted a way to turn it into a feature instead of an eyesore—without a complicated renovation.
From Flat Siding to a High-Impact Stone Feature
Instead of rebuilding the chimney, we installed stone veneer directly over the existing surface. This gave the chimney a completely new look, adding depth, texture, and architectural presence.
✅ Installed over existing exterior
✅ No structural changes required
✅ Adds height and visual interest
✅ Completed in days, not weeks
A Complete Chimney Transformation Without a Full Remodel
Before
The Goal
- Plain siding chimney lacked detail
- Drew attention in a negative way
- Didn’t match the home’s style
- Looked unfinished and outdated
After
The Solution
- Add stone veneer to the chimney exterior
- Create a vertical focal point
- Introduce texture and contrast
- Upgrade curb appeal instantly
What Does a Chimney Makeover Like This Cost?
Projects like this typically range between $3,000–$10,000, depending on height and access. Much more affordable than rebuilding—and far less invasive.
Project Details
- Products Used: Panels, Corners
- Color: Northern Slate
- Install: Over Existing Siding
Yes, GenStone can be installed over any flat surface as long as the substrate is structural. To install over concrete, brick or stucco we recommend using Tapcon screws and construction adhesive. For all other substrates, deck screws are the recommended fastener.
Yes, GenStone is engineered for exterior use and will endure the elements like any other siding product.
GenStone can be installed over any flat, sturdy surface.
GenStone is as simple as measure, cut and attach. A chimney like the one featured in this article would take two people about a day and a half and one person no longer than two or three days to complete.
Northern Slate was chosen to give the chimney a clean, modern stone appearance that contrasts the siding and adds depth to the exterior.
