"This service was for a rental property I own in NYC. It took some time and several phone calls to coordinate the estimate. The part (ceiling light fixture) needed to be ordered then arranging the service with my tenant took more time. Eventually, the light fixture was repaired satisfactorily. The serviceman was pleasant and courteous. Getting a small job completed in NYC is a daunting task."

"Dave figured out the best solution.  He and his worker dug the trenches and covered the pipes with the patches of grass after they installed the pipes, pump, & pop-up drain.  It was a very professional job and works great so far.  I have not seen the yard flooded since he did this work.  He kept in touch with me by phone and email since I was not there the whole time as it is my summer home. 
This is the third time I had Dave back to do work.  I had major damage from Hurricane Sandy and on 4/13/13 he also did work for me.  He worked in my crawl space.  He replaced insulation, cleaned joists with an antimicrobial agent and then painted them with antimold resistant paint, replaced a vapor barrier, installed a sump pump, repaired foundation vents, and filled cracks in my foundation.  All for a resonable price!  Dave is honest, fair and very professional.  He always returns my calls in a timely manner.  I will call on him again for future work.

Dock Building and Repair FAQs, answered by experts

It is possible to build your own dock, especially for simpler projects like a small floating dock, provided you are an experienced DIYer. However, dock building is a complicated process, and hiring a professional is recommended for larger, more complex projects that involve installing pilings or engineering a suspension structure.

A professional dock builder will have the necessary tools and skills to set post foundations, ensure proper anchoring, and build a safe, durable structure that can withstand marine conditions for decades. They are also knowledgeable about local regulations and permitting requirements. In some areas, it is illegal for anyone without a marine construction license to build a dock. Hiring a professional helps avoid these potential legal headaches and ensures the project is completed safely and correctly.

Common choices include pressure-treated wood, composite decking, and aluminum for durability and low maintenance.

The cost to build a new dock can range widely, typically from $5,000 to $65,000, with an average cost around $15,500. The final price depends on several key factors, including the dock's size, the materials used, the complexity of the installation, the depth of the water, the type of dock being built, and whether it is in fresh or salt water.

When deciding how big of a dock you can build, you should check with your city and state for any restrictions. Some cities won’t allow docks larger than one-fourth of the width of a body of water, while others have no restrictions at all. Gather this information when you apply for your permits so you can plan the build accordingly.

Most dock builds take 1-4 weeks, depending on design, permitting, and weather conditions.
