"Project started and finished on time. Installers were very professional with no noticeable damage to lawn. This crew of three was well organized and supervised and watching them work gave me great confidence that the job would be done right. Please consider getting the amazing wireless controllers. Very satisfied with this job and Pacific. I honestly don’t think you will find a better company to install sprinklers. Price was competitive."

"Tom and his crew took on the reseeding of my lawn front and back and both sides of my home. With ease that only cones with knowledge and experience Tom and his crew completely reseeded the lawn. In 2 visits both the top soil and reseeding was laid down. My lawn is not perfect when it comes to being even. C. C. Took great care in laying the top soil to help even out the lawn. Tom offered his sound advice about the watering process. With patience and diligent watering the grass seedlings sprouted evenly. Tom made sure to stop by to observe and offer suggestions to ensure continued growth and a thick lawn. Since then Tom and his crew have bern scheduled to cut and clean my lawn. Correct Construction also performed other projects which i will gladly offer my review. Robert H John H"

"Every person Iâ ve come into contact with at Sebonac has been friendly and professional. For me personally, one of the most important things, and what Iâ ve had problems with in other companies, is communication. These guys pick up the phone when I call, and if they canâ t they immediately call back. Iâ ve worked with a lot of different companies through the years and their prices are fair and just overall I really like their attitude when it comes to problem solving or working through any issues I have. There good people and do good work."

Lawns FAQs, answered by experts

Trimming or removing trees promotes safety, prevents interference with structures or utilities, and enhances the aesthetic and health of the property landscape.

If your dog always does their business in the yard, daily poop pick-up makes sense. The nitrogen in the poop can start making its way into the grass and surrounding soil quickly, a rain shower can send the waste into waterways, and less poop lying around means less chance of stepping on it accidentally. 

No, you shouldn’t vacuum artificial grass, particularly if you lay your synthetic grass with infill. Vacuuming could suction it up and loosen the connection between the grass and the ground.

Always do a poop sweep before mowing your lawn. Running your mower over dog waste can be messy, unsanitary, and smelly, and it can spread the poop to other parts of your lawn. Plus, you won’t be able to get it out of the grass (or the mower blades) easily.

A pre-emergent herbicide is the most effective way to avoid stickers growing in your yard. However, if some manage to make it through, a post-emergent herbicide is the most effective way to kill them. However, environmental concerns exist when using chemicals on a lawn. Try vinegar or baking soda applications to kill sticker plants for a more natural yet still effective method.
