"My husband and I reached out to the company to repair some rotten boards we discovered on the exterior of the house. We spoke to David who was extremely responsive and quick to set up our services. The crew came a couple days later right at the time they said, the repairs are great quality, and everyone we interacted with was polite and kind. I wouldnâ t hesitate to hire them for a bigger job in the future!"

"Very thorough in doing what they said they would do. Oscar was the only contractor I spoke with that understood what I wanted - not a traditional green lawn, but a lawn I could transition to a semi wild scape type of garden.neat with cleanup. Iâ m hoping it comes up as indicated"

Excavating questions, answered by experts

Because decomposed granite is a durable material, a crushed rock or gravel base is optional as long as the DG is properly installed and compacted. However, installing a base is a good idea because it will ensure proper drainage and stability and act as a weed suppressant (although you may still occasionally have to pull weeds). Installing an adequate base can also increase the durability of driveways and walkways. If you forego the paver base or gravel underneath, line the area with landscaping fabric to avoid weeds.

It can take several weeks for the ground to settle after removing a tree, and the soil under larger, more mature trees can take months. The deeper the tree has been ground under the soil, the longer it will take to settle. However, this extra depth can help you plant new landscaping sooner because you’ll have more space for fresh soil.

It’s possible to transplant trees as tall as 50 feet when an experienced tree planting service uses the right equipment. However, a tree with a trunk larger than two or three inches in diameter needs to be handled by a professional in order to yield successful transplanting results. Consulting a tree planting professional is the best way to tell if your large tree can be safely transplanted.

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Yes, you can install a trench drain if you already have concrete in your yard or garden. While it can complicate some aspects of the job and slightly run up the cost, it is doable. Residential trench drains can be easily retrofitted to outdoor areas with concrete without having to remove excessive amounts of your patio, pool area, or decorative walkways.
