The service
What caulking & weatherproofing is, what a visit covers and where the line is.
The short answer
Caulking and weatherproofing means walking the outside of a house, cutting out cracked and failed sealant, and applying new caulk or sealant at windows, doors, trim joints, siding seams and pipe and wire penetrations. Caulking & Weatherproofing in Santa Clara is booked through pros who cover its 7 ZIP codes, in neighborhoods such as Old Quad, Forest Park, and Killarney Farms. In Santa Clara, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain. The independent pro you choose sets the price and the warranty for this work.

What shapes a caulking & weatherproofing job
These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.
What is not part of caulking & weatherproofing
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- A weatherproofing job that reaches $1,000 in labor and materials goes to a licensed contractor, and NorTech flags this before you book.
- Replacing windows, doors, flashing or siding that has failed is a separate service, not part of a caulking visit.
- Roof leaks, chimney repairs and gutter problems are separate services on NorTech.
- Insulation, air-sealing in the attic or crawl space, and whole-house air leakage testing are separate services.
- Removing paint or caulk containing lead or asbestos in older homes without telling your pro first. The pro needs to know the age of the home before starting.

Before you book caulking & weatherproofing
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Walk the house and mark problem joints
Check every window, door, corner board, vent and pipe. Mark cracked, gapped or missing caulk with painters tape.
Do the business-card test
Slide a business card into the gap between a frame and the wall. If it goes in, air and water can too.
Check for stains inside
Look at window sills, corners and the ceiling below for stains, soft paint or musty smells. They show water is coming through, and the pro should start with those windows.
Decide if you will repaint
If paint is planned, say so in your notes. The pro will use paintable products and schedule the caulk before the paint.
Know your window and siding types
Note whether windows are wood, vinyl or aluminum and what the house is clad in. Different surfaces take different sealants, and the pro can bring the right ones.
Check the weather and reach
Choose a dry spell, and make sure ladders can reach the upper windows. Tell the pro about tall walls, locked gates and pets so nothing delays the visit.
Say where in Santa Clara you are
Add your neighborhood, for example Old Quad, Forest Park, and Killarney Farms, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.

Best time to book caulking & weatherproofing
Sealants cure best between about 40 and 80 degrees on dry surfaces. Doing the work in early fall seals the house before wet weather and cold, and in spring it repairs the damage of winter. Avoid rainy days and frozen surfaces. In Santa Clara, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain.
