Exterior Wall Waterproofing

Which side of the building is affected?

Water after wind-driven rain

Tell us which room and side of the building are affected. Include whether the problem appears only when rain comes from a particular direction.

Cracked or worn finishes

Photos of accessible areas help show the existing surface. Mention loose finishes or previous patching without climbing to inspect them.

Recurring water near openings

Water near windows or wall connections needs attention to the surrounding details. Coating the broad wall surface alone may not address every entry point.

Repairs and finishes need to work together.

A proposed wall treatment should consider the existing masonry or stucco, the condition of previous finishes, and how the wall meets adjacent surfaces. Ask which repairs and preparation are included and where the protective treatment will be applied.

A confirmed Corona example

At one Corona home, water was entering through the left side of the house. Unico completed stucco work on that side, followed by Thorocoat. The appropriate treatment for another property depends on its condition.

Choose for the existing surface

An existing coating, bare masonry, and damaged stucco are different starting points. Product suitability and surface preparation should be discussed before a finish is selected.

What affects the cost?

An estimate should reflect the actual area and work proposed for your property. Useful points to discuss include:

Access to the work
Height, nearby structures, and any finishes or obstructions around the affected area.
Preparation and repairs
What must be cleaned, removed, or repaired before a treatment can be applied.
Scope and materials
The area being treated, specified materials, and any work needed to restore disturbed surfaces.

Exterior Wall Waterproofing questions

What is the best waterproofing method for exterior walls?

It depends on the wall material, existing finish, condition, and water-entry details. A suitable proposal explains preparation and repairs as well as the chosen protective treatment.

How much does exterior wall waterproofing cost?

Wall area, height, access, repairs, preparation, and the specified treatment affect cost. A small accessible wall and a tall building elevation can involve very different work.

What are common problems with wall waterproofing?

Treating over loose or unsuitable finishes and overlooking cracks or connections can leave the cause of water entry unresolved. Ask what the scope includes beyond applying the finish.

Will waterproof paint stop a wall leak?

A surface product should not be assumed to fix every leak. The source may involve a crack, opening, or connection that needs separate attention. Discuss the wall condition and entry points first.
