Winter moisture wrecks absolute havoc on showers and tubs, especially in older homes and coastal areas. Leaky caulking, moldy grout, and inefficient seals significanlty increase heating costs and lead to long-term water damage.
In our new blog in the series, we’ll cover 5 winter-ready shower and caulking upgrades for all homeowners, renters, and businesses to prevent water damage, save energy, and improve comfort. And of course, when you need help, we The Handy Geeks (highest rated handyman in all of Cali) will be there with fully insured, professional and timely help.
1. Re-Caulk Around Your Shower & Tub ($15–$40)
Winter humidity and condensation can cause old caulking to crack and peel, leading to water leaks and mold buildup.
What It Does
• Prevents water damage to drywall and flooring
• Stops mold from forming behind tiles
• Keeps moisture contained within your shower or tub area
• Restores the clean look of your bathroom
Average Cost (California)
$15–$40 for high-quality silicone caulk.
Time to Complete
45–60 minutes for a small shower.
Our Tip:
If your caulking is cracking or peeling repeatedly, the surface may need to be cleaned and prepped better. We can remove old caulking for you and reapply a fresh seal to ensure a long-lasting, leak-free barrier.

Average Cost (California)
$15–$30 for grout sealer.
Time to Complete

5. Install a Bathroom Exhaust Fan ($50–$100)
A powerful exhaust fan is essential in keeping bathroom air dry during the wet months.
What It Does
• Removes excess moisture and humidity

Average Cost (California)
$50–$100 for an energy-efficient fan.
