"THANK YOU to the two men who replaced my fence six posts and a section of pickets yesterday. They worked well together. They listened to me before and after their work. They worked steadfastly through the morning. Much appreciated here. If I were their employer, I would keep these men."

"Noe and his crew did a great job. He worked with us in selecting the plants and took the time to explain what he thought would work. They paid attention to details and it turned out even better then we expected. We have received several compliments from our neighbors, and I will contact them again when we redo our backyard."

"I called Keith to fill in a big hole in my back yard that was left over from an above-ground pool I had just removed. He gave me a very reasonable price estimate and we scheduled a date for the job to be done. He had to reschedule twice due to conflicts with other jobs he was working on. I wasn't in a big hurry to get the job done and my schedule was flexible, so it didn't really matter to me. When he did finally come, Keith and his crew did great work - well above my expectations. I was charged exactly what the price estimate was. I would definitely hire these guys again to work on my yard."

Animal Fencing FAQs, answered by experts

No, skunks are not considered aggressive and are typically very gentle, mild-mannered creatures. However, when they’re provoked, they do emit their potent spray as a defense mechanism. Skunks are also useful creatures to have near your property since they eat insects and will likely leave you and your pets alone unless they’re startled.

How long skunks stick around depends on the time of year and whether they have youngsters. Skunks only spend a few days in a den during warm months. However, they’ll put down roots during the other seasons, particularly females with kits. Female skunks may stay in the same place throughout early spring and summer, and all skunks usually stick around during the winter months. No matter the season, skunks prefer safe areas with plenty of access to food. 

Iguanas cause a variety of damage to properties and pose other dangers. Their tunnels can collapse seawalls and foundations. They destroy native plants, trees, gardens, and agriculture. They compete with native animals for food. Their droppings, left almost anywhere, can transmit salmonella which is especially dangerous to vulnerable groups like children and the elderly.

Some animals, such as bats or birds, will be able to get out of chimneys on their own since they can fly. Other animals, however, may have a harder time and will require the help of a professional to escape. Squirrels and raccoons in particular may become stuck inside a chimney, especially if you have a buildup of soot or creosote inside. This can prevent them from being able to climb out, in which case you’ll need to call an animal control expert to help remove them.

The nine-banded armadillo is common in Texas, Louisiana, Florida, and Mississippi. Their range has expanded over the years, and they now live as far north as Missouri, Kansas, and even southern parts of Nebraska.
