Who Replaces Caulking, Sealants and Window Gaskets on Nashville High-Rises?

Squeegee Squad Nashville is locally owned and operated, and replaces caulking, sealants and window gaskets on commercial buildings across Nashville, Brentwood and Franklin, including towers of 30+ stories. We do it by rope access, so the work can often get done without a lift or scaffolding. If the sealant around your windows is cracked, pulling away or missing, it’s worth fixing before winter rain finds the gaps.

We’re also the crew that cleans the glass, so property managers can have caulking checked while the windows are being cleaned. Here’s what to look for, how the work is done and how to pick a contractor.

Who replaces caulking and sealants on commercial buildings in Nashville?

Squeegee Squad Nashville replaces caulking and perimeter sealant around windows, storefronts and facade joints, replaces worn window gaskets, and handles window leak repair at heights. On a mid-rise or a tower, that takes a crew that can work the facade from the top down. Our own crews do the work. We’re fully insured, NetVendor credentialed, and RealPage and OPS Merchant compliant.

What are the signs that commercial caulking needs to be replaced?

Sealant rarely fails all at once. It’s more of a slow quit. On your next walk-through, look for:

• Cracks or splits running along the joint
• Caulk pulling away from the glass, frame or masonry on one side
• Gaps where sections of sealant are missing
• Sealant that has turned hard, chalky or brittle
• Window gaskets that have shrunk, cracked or slipped out of the frame
• Water stains on interior sills, ceilings or walls near windows
• Drafts around closed windows, or leak complaints from tenants after storms

Why does sealant wear out on Nashville buildings?

Middle Tennessee is hard on caulk. Summer sun breaks down the surface, hot afternoons and cold nights make joints expand and shrink, and heavy spring and fall rains test every weak spot. Over time the sealant loses its stretch. Once it can’t move with the building, it cracks or lets go.

That’s why it pays to have perimeter sealant looked at regularly instead of waiting for a leak. The easy way: have it checked while your windows are being cleaned, since the crew is already on the building.

What does caulking and gasket replacement at heights involve?

On low buildings, joints can be reached from the ground or a lift. On taller buildings, our crews work on ropes, moving down the facade one section at a time. That’s often the less disruptive option: no lift in the parking lot and no scaffolding over the sidewalk. The general process looks like this:

1. Walk the building, note the joints and windows that need work, and put it in a written scope and schedule for the property.
2. Remove the old, failed sealant and prep the joint.
3. Install new sealant matched to the materials on each side of the joint.
4. Replace gaskets that have shrunk or cracked.
5. Send you photos and video of the work when the job’s done.

If water is already getting in, window leak repair at heights can be part of the same project. You can read more about our caulking, sealant replacement and window leak repair services, or about our high-rise window cleaning in Nashville.

What do you use to clean around sealants and gaskets?

We clean a lot of glass with water-fed poles that run on purified water, so most windows don’t need soap. We use cleaning products only when a stain, mineral deposit or construction debris calls for them. And since the crew is right there at the joint, it’s a good time to spot sealant that’s starting to fail. For more on scoping exterior cleaning, see our post on what a commercial pressure washing scope should cover.

What affects the cost of commercial caulking replacement in Nashville?

Every building is different, so the number depends on the job. The main things that move it:

• How many windows and joints need work
• Building height and how the joints are reached (ground, lift or rope access)
• The condition of the old sealant and how much has to come out
• Whether window gaskets need replacing too
• Scheduling around tenants, entrances and busy hours
• Whether the work is planned alongside window cleaning

How do I choose a contractor for caulking and sealant replacement?
