I provide residential structural engineering services to both homeowners and home improvement contractors. These services include plan preparation, design of structural members, structural evaluations of existing buildings, review of plans prepared by others, design of sanitary systems and on site drainage systems if necessary. All work is done by me, a registered professional engineer in New York, and I also conduct inspections and evaluations.

"Was Awful. Measurment's were off. Plans were incomplete. After he measured the rooms, we had to remeasure the rooms ourselves and send them to him. I then had to go to his house to pick up the plans. I submitted the plans at which time I was told that I needed to get then done again by a professional. Held up the construction by several weeks. Save your money. Do not use Lou."

Treehouse Builders questions, answered by experts

The amount of time it takes for a tree trunk to rot depends on several factors, including the tree’s size, species, and environmental conditions. It can take anywhere from a few years to several decades for a tree’s trunk to rot. A tree stump, on the other hand, can take up to 10 years to disappear after it’s decayed naturally.

Aside from removing dead or diseased branches, you should prune your trees somewhere between every one and three years. Some people—particularly commercial farmers—prune their apple trees yearly to produce higher yields. This is the best way to promote tree health. That said, the average homeowner can get away with hard-pruning their mature apple tree every other year or every three years. 

You should not trim an oak tree in the summer. Oak trees are especially susceptible to disease, and open tree wounds are an invitation for beetles that carry tree-killing fungus. If there’s no risk that the oak tree will do damage to your property or hurt someone, it’s best to save the trimming for fall or winter. If you can, seal the wound with latex to prevent fungus from getting inside.

Trimming your palm trees once or twice per year keeps them healthy and robust. Caring for palm trees includes cutting off brown leaves to prevent wildfires and pathway obstruction. However, you don’t want to over-trim the palm tree. Cutting too many branches off will weaken the tree and prevent future growth. And it’s essential to have a strong, healthy palm tree during hurricane season to prevent safety risks or property damage.

The cost of professional tree trimming is $460 on average. The price could range from $75 to $1,800, depending on the size and type of the tree and the time of year. Tree trimming services are typically more costly in the spring, so waiting until the off-season might save you some money on this project.

The type of tree vastly impacts the overall cost, mainly due to the size of the branches. For example, trimming Crepe Myrtle trees cost an average of $80 to $400, whereas giant pine trees can range from $200 to $1,800.
