Failing Caulk Won’t Wait. Neither Do We.

Every gap in a worn caulk line is an open door for water — and water damage costs far more to fix than the seal that would have stopped it. Get a licensed Twin Cities caulking contractor on it fast.

What Is Caulking, and Why Does It Matter for Your Building?

Caulking is a flexible sealing compound that fills gaps and joints to block water, air, dirt, insects, and fine debris from entering a structure, penetrating masonry, or rotting wood framing. A sound caulk line creates an airtight, watertight barrier that keeps your building dry, stops drafts, and lowers heating and cooling costs season after season.

The right caulk is never one-size-fits-all. The correct product depends on the surface, the joint, and the exposure. Silicone seals beautifully on nonporous surfaces but resists paint and adheres poorly to wood.

BEI Exterior Maintenance assesses every type of exterior building material and joint to match it with the ideal caulk and sealant.

Our Commercial Caulking & Sealing Services

Window & Door Caulking and Sealant Replacement

Buildings lose the most air around exterior doors and windows. Even sealant that was applied correctly at install will age, harden, and lose its elasticity over time. When a caulk line stops performing, it needs full removal and replacement — not a patch. Our window caulking service removes old, failing sealant and applies a fresh, weather-resistant seal that keeps interiors warmer in winter and comfortable in summer. We also handle window caulking replacement across entire multi-family and commercial buildings.

Concrete Caulking & Joint Sealing

Open gaps and cracks in concrete are a safety hazard for tenants, staff, and guests, and they let moisture work below the surface. As your concrete caulking contractor, BEI seals control joints, expansion joints, and cracks with the correct application to protect the slab and extend its service life. Our concrete joint sealing protects walkways, plazas, and driveways from further deterioration.

Masonry, Building Envelope & Waterproofing

Water that gets behind brick and block does its damage out of sight. BEI provides masonry sealing, joint sealing, and caulking and waterproofing services that protect the building envelope at the points most likely to fail — control joints, through-wall penetrations, and the transitions between dissimilar materials.

Exterior Siding & Trim Caulking

Properly sealed siding, trim, and penetrations keep wind-driven moisture out of the wall assembly. BEI matches the right exterior caulk to your siding type so the seal holds, flexes, and stays put through Minnesota’s freeze-and-thaw cycles.

Whether you manage a single property or a portfolio, BEI scales to the job. We are an experienced commercial caulking contractor for office buildings, retail, and industrial properties, the contractor of choice for multi-family and association living, and a trusted provider of residential caulking for homeowners across the metro.

Why Property Managers Choose BEI as Their Caulking Contractor

We are a licensed commercial caulking company (License #BC241131) with a long track record across the Twin Cities. Our professional caulking services pair the highest-quality sealant products with skilled installers who understand how Minnesota’s freeze-thaw cycles attack a poorly sealed joint. We show up on time, work cleanly, and stand behind the result — straightforward, honest work from a team that treats your property like its own.

Trusted Across Twin Cities Property Management

BEI is an active member of the organizations that shape multi-family and association management in the metro — MHA, CIC Midwest, BAM, MCCAI, and BATC. Property managers choose us because we work within association requirements, communicate clearly, and act like a long-term partner. That’s what makes us the contractor of choice for multi-family living.

How Much Does Commercial Caulking Cost?

Honest answer: it depends on the job. Commercial caulking is most often priced per linear foot, and the rate is driven by the type of sealant, the height and access of the joints, the amount of old caulk that must be removed, and the total footage. Rather than quote a number that may not fit your building, we’ll walk the property, scope the work, and give you a clear, itemized estimate before anything starts. Request a free consultation and we’ll put real pricing in front of you.

When you hire BEI, you get a licensed Twin Cities caulking contractor that arrives on time, works cleanly, and does the job right the first time.

Frequently Asked Questions: Caulking

Caulking is a flexible sealing compound used to fill gaps and joints in a building. It blocks water, air, dirt, and insects from getting in, keeps masonry and wood framing dry, and helps maintain an airtight, energy-efficient structure

The terms are often used interchangeably. In practice, “caulk” tends to describe lower-movement, paintable products (such as acrylic-latex), while “sealant” usually refers to high-performance, high-movement products like silicone and polyurethane used on commercial joints. BEI selects the product class that fits the joint and the material.

Siding should be caulked at the right locations — around windows, doors, trim, and penetrations — but not everywhere, since some joints are designed to breathe. The best caulk for exterior siding is a high-quality, paintable, flexible exterior product matched to your specific siding material. Our team identifies which joints to seal and which to leave open.

Caulking brick and masonry starts with removing failed or deteriorated material and cleaning the joint so the new sealant can bond. We then apply a backer rod where needed and tool in a flexible, masonry-rated sealant that allows the wall to move without cracking the seal. Using the wrong product on masonry traps moisture, so material selection matters

Caulk has a service life. Polyurethane sealants typically last five to ten years before they need replacement, while silicone sealants can perform up to twenty years. Exposure, sun, movement, and the original installation quality all affect how long a joint holds.

For exterior joints on office and commercial buildings, high-performance silicone and polyurethane sealants are the leading choices. Silicone resists UV, temperature swings, and chemical exposure and holds its elasticity over a wide range, while polyurethane offers strong adhesion, movement capability, and paintability. BEI specifies the product based on the joint design, substrate, and exposure rather than a single default.

Some products, such as acrylic-latex sealants, can be painted. Silicone generally cannot, because its chemistry resists paint adhesion. If a joint needs to be painted, we choose a paintable sealant from the start.

If your caulk is peeling, cracking, shrinking, or missing in spots, it needs immediate attention. Discoloration, or a line that feels soft and spongy, also signals it’s time for a new sealant. Don’t wait on obvious signs of caulk failure — small gaps turn into water damage fast.

One Contractor for Your Whole Building, Not Just the Caulk

Most caulking outfits only caulk. BEI is built differently. Because the same company also handles your roofing, siding, gutters, masonry, concrete, and windows, the crew sealing your joints already understands how the entire building works together. You get one accountable vendor for every exterior repair — your one call for property repairs and replacements — instead of chasing five.
