Caulking Services in Leesburg, VA
Professional Caulking & Sealing for Leesburg Homes
Alzamora Services Inc. is a family-owned, licensed and insured home improvement company based in Leesburg, Virginia. For more than 10 years, we’ve helped Loudoun County homeowners seal out water, drafts, and pests with careful caulking around windows, doors, tubs, showers, sinks, and exterior trim.
Cracked or missing caulk may look like a small problem, but it lets moisture behind walls, invites mold in bathrooms, and lets heated or cooled air escape. We remove old, failing caulk, clean and prep each joint, and apply the right sealant for the job, leaving smooth, neat lines that protect your home and look great.

Local Expertise
Why Caulk Fails Faster in Northern Virginia
Loudoun County’s weather puts constant stress on caulk joints. Knowing what causes failure helps us choose the right sealant and seal it to last.
- Freeze-thaw cycles expand and shrink joints until caulk cracks and pulls away
- Humid summers encourage mold and mildew in bathroom caulk
- Strong summer sun dries out and hardens exterior caulk over time
- Winter drafts through unsealed gaps make homes harder to heat

FAQ
Caulking Service FAQs
How often should caulk be replaced?
It depends on where it is. Bathroom and kitchen caulk should be replaced when it cracks, peels, or shows mold. Exterior caulk usually lasts several years but should be checked regularly, especially after harsh winters.
Do you remove the old caulk first?
Yes. Applying new caulk over old caulk leads to poor adhesion and early failure. We remove the old caulk completely and clean the joint before sealing.
How long before I can use my shower after recaulking?
Cure time depends on the sealant. Many bathroom sealants need about a day before they can get wet. We’ll tell you the exact cure time for the product we use.
Can caulking help lower my energy bills?
Sealing gaps around windows, doors, and other openings reduces drafts, which can help your heating and cooling system work more efficiently.
Are you licensed and insured?
Yes. Alzamora Services Inc. is a licensed and insured contractor in the Commonwealth of Virginia. Call (703) 955-9929 to schedule your free estimate.
