The Lanhams arrived within an hour of my initial call for a busted pipe. The plumber quickly diagnosed the source of the leak and fixed the problem. Everything was cleaned up well no trash left behind. The guys were very friendly throughout. Highly recommend for prompt, professional service.Posted on Autumn JohnsonTrustindex verifies that the original source of the review is Google. Absolutely an amazing service experience. Professional and quick to respond to the service request - within 24 hrs called me. They were booked for the week, but had a cancellation and were able to come out the same day. Even though my service request was an insurance claim, and we weren’t sure if the repairs would be covered, the owner of Lanham’s got right to work and quickly resolved the issues with my shower and toilets. He not only showed amazing customer service, but treated me with kindness and told me he would take great care whether the insurance covered the services or not. He went above and beyond and was in and out in less than 40 minutes. Everything works great now. Highly recommended Lanham’s for all of the Galveston county area. 🌟🌟🌟🌟🌟Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

We identify the issue, repair or replace the faulty parts, and retest the system until it meets the required standards.
Yes. All tests are completed by certified backflow technicians who provide official documentation for city records.
A typical test takes 20–45 minutes, depending on system size and accessibility.
