Sealing the joint between a window and brick calls for a caulk that can bond to the materials around the gap and handle outdoor exposure. The right choice depends on the frame material, whether you need a paintable finish, and how much sealant the job requires. These five options include silicone, siliconized acrylic, and a rubber-based sealant; check the product label for compatibility with your exact surfaces before you apply one.

Our Picks: Best Caulk For Windows And Brick reviews
Red Devil Silicon Acrylic Caulk for Everyday Window and Door Sealing
Red Devil’s silicon acrylic caulk is made for interior and exterior window and door projects. The 10.1-ounce tube is a practical format for sealing a longer run than a small touch-up tube can cover, and the listed water cleanup can make application cleanup simpler.
The product description also lists a 35-year limited warranty and says it is made in the USA. Those details may appeal to homeowners looking for a conventional caulk for routine sealing work. However, the supplied product information does not specifically name brick or masonry as compatible surfaces. If your bead will contact brick, check the package instructions before choosing it.
Compared with the GE silicone options below, this is the alternative to consider when water cleanup matters more than a specifically stated silicone formula. The cedar color may also be a better visual fit for some trim, but it may not blend with a white or clear window joint.
Pros:
- Listed for interior and exterior use
- Water cleanup is specified
- 10.1-ounce tube suits longer sealing runs
- Includes a listed 35-year limited warranty
Cons:
- Brick and masonry compatibility is not stated in the supplied description
- Cedar color may not match every frame or wall
Verdict: Choose Red Devil for a general window or door job where its color and water-cleanup formula fit, but confirm that it is suitable for the brick if the joint touches masonry.
GE Clear Silicone in a Compact Tube for Small Masonry Joints
This clear, 2.8-ounce GE tube is a 100% silicone sealant for window and door work. Its product description specifically lists brick, stone, stucco, masonry, cement board, glass, and several other materials as compatible. That makes it the most directly documented choice here for a small joint where the sealant must meet brick as well as a window or door surface.
The description says the cured sealant is permanently flexible, resistant to shrinking and cracking from temperature changes, and rain-ready in as little as 30 minutes. It also states 10-year product protection and resistance to stain-causing mold and mildew growth. These are manufacturer-listed claims; follow the package directions for application and curing conditions.
The small tube is handy for a limited repair, but it is less practical for a long perimeter or several windows. Clear can work when you do not want a colored bead, though it will not hide an uneven joint. As with other silicone products, confirm whether the cured finish suits any plans to paint the surrounding area.
Pros:
- Product description explicitly lists brick and masonry compatibility
- Clear finish for a less visible bead on suitable surfaces
- Described as permanently flexible and weatherproof
- Rain-ready in as little as 30 minutes, according to the description
Cons:
- Small tube is better suited to repairs than long runs
- Clear sealant may show dirt or an uneven application line
Verdict: This is a strong fit for a small window-to-brick repair when you want clear silicone and the compact tube provides enough material.
GE White Silicone for Longer Window and Door Seams
This 10.1-ounce GE tube offers the same general window-and-door silicone approach as the clear option, but in white and in a larger format. It may be a more convenient choice for a longer bead or several joints where white better matches the frame. The product description identifies it as 100% waterproof and weatherproof silicone.
GE says the formula stays flexible, resists shrinking and cracking as temperatures change, and becomes water-resistant in 30 minutes. It also describes the product as low odor with a neutral-cure formula and lists 10-year product protection. The supplied description does not provide the same detailed list of compatible materials as the clear tube, so check the label for brick or masonry compatibility before using it across a mixed-material joint.
Compared with the compact clear GE tube, this one offers more sealant and a visible white finish. That is helpful when white is the intended look, but less suitable when you need a transparent bead or plan to paint over the sealant.
Pros:
- 10.1-ounce size is suited to larger jobs than a small repair tube
- White finish can match some window and door frames
- Described as permanently flexible and resistant to shrinking and cracking
- Water-resistant in 30 minutes, according to the product description
Cons:
- White may stand out against brick or darker frames
- Confirm brick compatibility on the label before sealing a masonry joint
Verdict: Pick this GE tube for a larger white silicone job, and verify the surface instructions if the bead will bond directly to brick.
Liquid Rubber Sealant for Paintable Joints and Small Voids
Liquid Rubber describes this product as both a waterproof adhesive and a caulk for filling small voids or bridging joints, seams, vents, gaps, and protrusions. The two-pack gives you more material for multiple areas, and the product description states that each tube covers about 24 linear feet at a quarter-inch bead.
The sealant is white, non-slumping for overhead use, and paintable after 24 hours. The listing also says it can cure on damp surfaces and is UV resistant if left unpainted. Those features may be useful when the job calls for a paintable finish, but the supplied description does not specifically confirm window-to-brick compatibility. Check the product label for both surfaces and the intended application before using it on that joint.
Unlike the GE and Gorilla choices, this is not presented as a 100% silicone window sealant. Its broader adhesive and waterproofing role may suit varied repair work, but the stated cure and paint time means it is not the pick for someone who needs the shortest wait before painting.
Pros:
- Two tubes provide material for more than one repair
- Paintable after 24 hours, according to the description
- Described as non-slumping and suitable for overhead use
- Listing states it can cure on damp surfaces
Cons:
- Window-to-brick compatibility is not specifically stated in the supplied description
- Requires a 24-hour wait before painting
Verdict: Consider Liquid Rubber when paintability and a multipurpose sealant matter, but confirm it is approved for the exact window-frame and brick surfaces in your project.
Gorilla Clear Silicone for Quick Window and Door Touch-Ups
Gorilla’s clear 2.8-ounce tube is designed for window and door sealing, including touch-ups around frames, siding, trim, vents, and exterior gaps. The product description calls it a 100% waterproof silicone sealant that stays flexible and is made to handle changing temperatures without shrinking or cracking.
The listing says the sealant can be exposed to water in as little as 30 minutes when applied as a 3/16-inch bead at 70°F and 50% humidity. That timing depends on the stated conditions, so check the package directions for your project. The description does not specifically name brick or masonry among its compatible surfaces, making that label check especially important for a window-to-brick seam.
Its small size makes sense for a few touch-ups, not necessarily for a whole window perimeter. The clear finish keeps the bead from adding a white or cedar-colored line, although clear caulk will not conceal gaps or rough application. Compared with the small GE tube, Gorilla’s description focuses on touch-up use, while GE explicitly lists brick and masonry compatibility.
Pros:
- Compact size suits small repairs and touch-ups
- Clear, 100% silicone formula is described as waterproof
- Designed to remain flexible through temperature changes
- Water-ready in 30 minutes under the stated application conditions
Cons:
- Small tube may not cover a long seam
- Brick compatibility is not stated in the supplied description
Verdict: Choose Gorilla for a small clear window or door touch-up, but use a product with confirmed brick compatibility when the joint meets masonry.
How to Choose Caulk for Windows and Brick
Confirm compatibility with both sides of the joint
A window-to-brick gap is a mixed-material joint. The sealant needs to adhere to the window frame and the masonry, so check the product label for both materials rather than relying only on “window and door” wording. Of these options, the clear GE silicone product description explicitly lists brick and masonry among compatible materials. For the others, confirm compatibility on the package before applying them to brick.
Choose a formula for the job, not just the label color
Silicone products in this list are described as waterproof and flexible, while Red Devil is a silicon acrylic formula and Liquid Rubber is described as a waterproof adhesive caulk. These formulas have different application and finish considerations. If you expect to paint the bead, look for clear paintability instructions: Liquid Rubber is listed as paintable after 24 hours, while the supplied descriptions do not identify the silicone products as paintable.
Match the tube size to the repair
A small tube can be convenient for a short gap or one touch-up, while a 10-ounce tube is more practical for a longer run. The GE clear and Gorilla tubes are 2.8 ounces; the Red Devil and white GE options are about 10 ounces. Liquid Rubber comes as a two-pack. Consider the length and width of the joint, and follow the label for bead size and coverage.
Think about color and the finished appearance
Clear caulk can keep a new line from adding a strong color contrast, but it will not hide a rough bead. White can blend with a light frame, while the Red Devil product is cedar-colored. Choose a shade that suits both the frame and the surrounding brick, and remember that a visible bead may look different across two materials.
Check water exposure and cure instructions
Outdoor joints need a sealant rated for the conditions they will face. Several products here are described as waterproof or weatherproof, and the GE and Gorilla listings state a 30-minute water-ready time under their specified conditions. Do not treat that as a substitute for full curing instructions. Temperature, humidity, bead size, and the product label all matter.
Prepare the joint before caulking
Remove loose or failed sealant and clear away dirt so the new bead can make contact with the surfaces. Follow the product’s instructions on whether the joint should be dry or may be damp; the Liquid Rubber description specifically says it can cure on damp surfaces, but that does not mean every product can be applied that way. Apply only where intended, and avoid blocking window drainage or weep openings.
Frequently Asked Questions
What is the best caulk for a window-to-brick joint?
Start with a product whose label confirms compatibility with both the window-frame material and masonry. The clear GE Advanced Silicone description specifically lists brick and masonry. For other choices, verify the package instructions before use.
Can I use regular window and door caulk on brick?
Not automatically. A product described for windows and doors may not list brick as a compatible surface. Check the label for the materials in your joint, especially when the bead must adhere to both a frame and masonry.
Is silicone caulk paintable?
Do not assume it is. The silicone products in this selection are not described as paintable in the supplied product information. If painting the finished joint is important, choose a sealant whose label clearly says it can be painted. Liquid Rubber is listed as paintable after 24 hours.
How long should I wait before exposing caulk to rain?
Follow the specific product instructions. The GE products and Gorilla listing describe water readiness in as little as 30 minutes, with timing or conditions that may vary. Do not apply that time to a different product or ignore its cure directions.
Should I use clear or white caulk around a window?
Choose based on the look you want and the surfaces involved. Clear avoids adding a white line, while white may blend with a light frame. Neither color hides a poorly shaped bead, so careful application and cleanup still matter.
Can I caulk over old sealant?
For a durable repair, remove loose or failed material and prepare the joint as the product label directs. New sealant may not bond well to a dirty or unstable surface. Avoid damaging the frame or masonry while removing old caulk.
Final Recommendation
For a small window-to-brick repair, the clear GE Advanced Silicone is the most straightforward pick in this group because its product description specifically lists brick and masonry compatibility. For longer white window seams, the larger GE tube offers more material, but confirm masonry compatibility on its label. If you need a paintable option, consider Liquid Rubber only after checking that its instructions cover both surfaces in your joint. No matter which caulk you choose, careful surface preparation and following the package directions are key to a sound seal.
