Our Residential Caulking Process

How we Help Homeowners

We will arrange a visit to see your home. In some cases, no one is required to be home for the quote.

1. Assess the Existing Caulking

We inspect the condition of the seals, substrates, joints and surrounding areas to identify visible failure and potential entry points.

2. Remove Failed Caulking

Existing deteriorated sealant is carefully removed so the new system can bond to properly prepared surfaces.

3. Prepare and Back the Joint

Surfaces are cleaned and prepared. Closed-cell backer rod or spray foam is installed where appropriate to support joint depth and performance.

4. Apply the Selected Sealant System

Our technicians install the appropriate commercial-grade or premium long-life sealant based on the service selected and the needs of the home.

5. Tool, Inspect and Clean the Area

Every joint is neatly tooled, visually inspected and finished before debris is removed from the work area.

6. Complete the Protection Walk-Around

Where included, we identify and seal additional openings that may allow insects or other unwanted pests to enter.

Professional exterior caulking helps protect your home from water infiltration, drafts and weather exposure while sealing vulnerable transitions between different building materials. This includes windows and doors, vents and penetrations, siding and trim, masonry joints, solariums, and landscape and hardscape transitions around walkways, foundations and pool areas.

Residential Caulking FAQs

How do I know when my caulking needs to be replaced?
Look for cracks, peeling, gaps or caulking that’s pulling away from the surface. You may also notice drafts, moisture or insects around your windows and doors. If you’re unsure, we can inspect it and let you know whether it needs replacing.
Do you remove existing caulking first?
Yes. We remove the old, failed caulking before installing the new sealant. New caulking won’t bond properly over damaged material, so this step helps create a cleaner and longer-lasting seal.
Can re-caulking help with drafts without replacing my windows?
Yes, if the drafts are coming through gaps around the window frame. Failed exterior caulking can let air and moisture into your home even when the windows are still in good condition. We’ll assess the area and help you determine whether re-caulking may solve the problem.
What’s the difference between Classic Seal and ForeverSeal?
Classic Seal is our industry-standard residential service. It includes commercial-grade caulking, proper joint backing and a 10-year no-crack, no-peel warranty.* ForeverSeal is our premium option. It uses an upgraded long-life sealant, follows our defined ForeverSeal installation process and is installed by ForeverSeal Certified Technicians. Eligible installations include a limited lifetime no-crack, no-peel warranty.*
Can residential caulking be completed year-round?
Yes, in many cases. We use professional sealants suited to different temperatures and weather conditions. The surfaces still need to be clean and dry, so rain, snow and excess moisture may affect scheduling.
