incorrectly used. They are a polymer based product to protect and fill joints between two
substrates that constitute a major function in a buildings life cycle.

Sealant Restoration

Like all construction materials, sealants have a lifespan and when they’ve reached that inevitable point it can no longer withstand stresses of the elements. We either mechanically remove existing and replace it
with new material or cover the existing with a pre-formed extrusion to keep the joint watertight.

Our last caulking service not only left gaps in some of the caulking strips, but also created uneven and unsightly globs of caulk around our windows. ProSeal was able to remove the bad product and put in new caulking in no time. Awesome experience and would definitely recommend!

Frequently asked questions – Caulking Services

What is Caulking?

Caulking is using a waterproof filler and sealant, used in building work and repairs.

Do I need to use different caulk products for different jobs?

In short yes, all caulks are different in formula and their intended purpose. Adhesion, flexibility, elasticity, and durability vary a lot from product to product so it is important to select the right product for each job you have.

Do I need to remove old caulk before caulking?

Before applying new caulk you usually do need to remove the old caulk. New caulk doesn’t stick to old caulk so normally if the old one is not removed it won’t seal properly.

How long does a sealant take to dry?

Usually a sealant can take only 24 hours to dry. However, if the sealant is required to be a bit more thick then it could take several days to dry.
