Sema Core Innovations did an amazing job cleaning up our front & back yards and planting new shrubbery. Highly recommend their services! They were able to finish the work within a week of contacting them and are very friendly and professional. We will definitely be using them again!

They were terrible. They were very late, did NOT level the soil as requested, the sod provided was bad quality, they did not use topsoil only sand, and the work was sloppy. They left dirt all over the sidewalk in front of house. It was a total waste of money. I will never use Sema Core or Angi ever again.

They do very fine work! The dig a deep trench down the side of my lawn, under the sidewalk, and on to the street to install a large pvc pipe. They re-installed the grass over the trench, and left NO trace that anything had even happened! Their pricing was very reasonable.

Tree Service
Yes, I recommend this pro
We had four very tall Japanese Blueberry trees that had been severely damaged by last winter’s freeze. The trees were about 35 foot tall and had to be cut back to about 6 feet to get back to the live growth. They were very close to our house, pool and fence. Santiago and his crew were courteous, very respectful of our property, and extremely professional in the way they handled the job. They made artfully use of ropes so that none of the big limbs really fell - they were gently lowered to the ground, avoiding damage to house, fence or pool. They also trimmed some big limbs from a neighbor’s tree that, over the years, had begun to hang very close to our roof. When finished, they cleaned up the yard, blew off the pool deck, and skimmed the pool to get rid of the little bit of debris that had fallen there. Their price was very reasonable, they arrived on schedule and were in and out in three hours.

I have used this tree service company for many years. They have always provided excellent and prompt service. My trees always look beautiful when they finish trimming them. I have also had them remove some trees for me in the past.
