Looking for someone to seal up our attic against rats

Over the years, I've used local independent business Pest Fighter (pestfighter.com) a handful of times and have always been happy with their service.

I highly recommend Attic Projects. I'm not sure they're the cheapest around, but they are thorough and have very high customer service. We had them redo the entire crawl space in our new house (it was really really gross). They guarantee their rodent proofing for 5 years. If you're not happy about how the team did something, they'll send someone out to make it right.

I was referred to @cleancrawls by a realtor colleague for my clients. They did a great job and client was happy.

Thank you all. I appreciate your help. I think we'll go with Attic Projects as long as we can pick and choose their services to just rodent proofing and not the full-meal deal of replacing all the attic insulation.

Dominon Pest Control got rid of the rats in our attic and they don't seem to have come back.

Rory from madronahomeservices.com did a fantastic job in our crawl space and roof, both sealing and insulating.
