At B&B Masonry (replace with company name if different), we specialize in mouse removal and entry point sealing in Columbia MD, focusing on stopping the infestation at the source. Rodents squeeze through openings as small as a dime. Unless those gaps are sealed properly, they’ll keep coming back.

Why Rodent Exclusion Is Critical in Columbia Homes

Homes in Columbia and throughout Howard County often have:


  • Soffit gaps
  • Unsealed utility penetrations
  • Garage door light leaks
  • Crawl space vent vulnerabilities


That’s how mice, roof rats, and other rodents enter.


Simply placing traps doesn’t solve the problem long-term.
