Getting a Trellis to Hold on Brick Without Any Drilling
Yes, you can absolutely build a sturdy trellis brick wall mount that holds up securely without ever drilling into a single brick or damaging any mortar joints in the process. Mortar joint clips grip the tight seam between bricks using spring tension, leaving the brick face itself completely untouched and fully intact throughout.
Key Takeaways
- Mortar joint clips grip the seam between bricks, not the brick face
- Standard mortar joints run about 3/8 inch thick, matching most clip hardware
- A basic trellis clip kit runs under $30 for a standard-sized panel
- Most installations take under an hour with basic hand tools
- Removing the clips leaves no mark on the brick or mortar
This guide covers the full no-drill method for a trellis brick wall mount, plus how to keep it secure as climbing plants add real weight over the growing season. Keep reading for the full five practical steps that work well on most standard brick walls and common mortar joint widths.
Why Mortar Joints Work Better Than Brick Faces for No-Drill Mounts
Brick faces are dense and fired hard, which makes them difficult to grip without a mechanical fastener. According to the Brick Industry Association, standard mortar joints measure about 3/8 inch thick, with 1/2 inch joints also common depending on the brick size used. The table below details the official joint-sizing guidance established by the Brick Industry Association.

That standard width is exactly why mortar joint clips work so reliably across different homes and brick styles. A clip sized for a 3/8 inch joint fits the vast majority of residential brick walls without any custom modification.
What You’ll Need Before You Start
Mortar joint trellis clips, a wire brush and a level handle most standard installations without any specialty tools. A tape measure helps space the clips evenly before you start attaching anything permanently.
For heavier trellis panels, look for clips rated specifically for the panel’s weight rather than assuming a lighter-duty clip will hold. A small putty knife is worth having too, for clearing any loose mortar debris from the joint before the clip goes in.
Installing a Trellis Brick Wall Mount: Step by Step
The full installation takes under an hour for a standard-sized panel, most of it spent on careful spacing rather than the attachment itself. Work through the steps in order for the most even, secure result.
Measure and Mark Mortar Joint Locations
Measure your trellis panel and mark where each clip needs to sit along the mortar joints, spacing them evenly across the width and height of the panel. Aim for a clip roughly every twelve to eighteen inches for standard lightweight trellis material.
Clean the Mortar Joints
Brush out each marked joint with a wire brush to remove loose debris, dust or old paint that could weaken the clip’s grip. A clean joint gives the clip’s spring tension something solid to bite into.
Attach the Mortar Joint Clips
Slide each clip into its marked joint and tighten according to the manufacturer’s instructions, checking that it sits flush and does not wobble. Work through all the marked points before moving on to the trellis itself.
Secure the Trellis to the Clips
Hold the trellis panel against the wall and hook or fasten it into each installed clip, starting from one corner and working across. A level check partway through catches any drift before the whole panel is attached.
Check Load Distribution and Adjust
Gently push on different sections of the mounted trellis to confirm every clip is carrying its share of the weight evenly. Add an extra clip to any section that flexes more than the rest.
Keeping Your Trellis Secure as Plants Grow
Climbing plants add real weight over a season, so a quick clip check each spring catches any that have loosened before a heavy vine puts real strain on them. Trimming plant growth back from directly overloading any single clip also helps distribute weight more evenly across the whole panel.

How Much Does It Cost to Mount a Trellis on Brick (Under $30)
A basic no-drill trellis brick wall mount typically costs under $30, covering a set of mortar joint clips and a standard trellis panel if not already owned. Larger or heavier-duty panels can push the total closer to $50 to $70.
Professional installation services generally charge $100 to $200 depending on wall size and panel weight. For a project this manageable, the DIY route saves real money without sacrificing a secure hold.
How Many Mortar Joint Clips Does a Trellis Need (6 Clips)
A standard-sized trellis panel typically needs around six mortar joint clips, spaced roughly every twelve to eighteen inches across the frame. Larger panels or heavier climbing plants benefit from additional clips concentrated along the bottom edge, where weight accumulates most.
Using fewer clips than recommended concentrates too much load on each remaining point, increasing the risk of one pulling loose as the plant matures.
How Long Does a No-Drill Trellis Mount Last (4 to 5 Years)
A properly installed mortar joint clip system typically lasts four to five years before the clips need replacing due to metal fatigue or corrosion. Clips in coastal or high-humidity climates may need replacement closer to the two to three-year mark.
Choosing stainless steel or powder-coated clips over basic zinc-plated hardware extends the usable lifespan meaningfully in most climates.
Conclusion
A trellis brick wall mount without drilling is often the sturdier long-term choice, since mortar joint clips distribute grip across several points instead of concentrating stress in a few drilled holes. The five steps above cover the spacing and attachment process that works on most standard brick walls.
Check your clips each spring as plants add weight and the mount holds securely season after season without a mark left on the brick. Try this method on your own wall this weekend, then tell us how it held up or share this guide with a friend whose brick patio could use the same upgrade.
Frequently Asked Questions (FAQs)
How do you install a trellis brick wall mount without drilling?
You install a trellis brick wall mount without drilling by attaching mortar joint clips into the seams between bricks, spacing them every twelve to eighteen inches, then securing the trellis panel into each clip and checking that the load distributes evenly across all points.
Do mortar joint clips damage brick?
Mortar joint clips do not damage brick when installed correctly, since they grip the mortar seam using spring tension rather than penetrating the brick face or mortar itself, leaving both completely intact after removal.
Can a heavy trellis be mounted without drilling?
Heavier trellis panels can be mounted without drilling by using more mortar joint clips spaced closer together and choosing clips specifically rated for higher weight capacities, though extremely heavy structures may still require a professional assessment.
Will mortar joint clips work on old or crumbling mortar?
Mortar joint clips need reasonably solid mortar to grip properly, so joints that are visibly crumbling or deteriorated should be repointed before installing clips, since the clip’s holding strength depends entirely on the mortar’s condition.
Is a brick wall trellis mount strong enough for climbing vines?
A properly spaced trellis brick wall mount handles most climbing vines without issue, though particularly heavy or woody vines like wisteria benefit from additional clips and a periodic check to confirm the mount is keeping pace with the plant’s growth.
