"I couldn't have asked for a better experience. They were hired to replace the main electrical panel/breakers at my elderly mother's home. Roni, the electrician, was a wonderful communicator, and was very knowledgeable and thorough in completing the job and in putting her at ease. The price was very reasonable. I will be using Nasr Electric in my own home, as well as recommending them to all my friends and family in the DMV area."

"Excellent customer service. Excellent finished product. West Shore Home came to install a shower in one bathroom and bathtub/shower in another bathroom. Their customer service is top tier! They took extra caution to ensure they didn’t damage or disrupt my home or other furniture as they carried their equipment in and out of the house. They encouraged me to see the progress as they worked. (Nothing to hide is always a good thing.)

"Patrick was professional from the time I reached out up until his arrival at my home. I explained that the control valve from my sump pump seemed to be malfunctioning over the phone, and within a couple of minutes of being on site and verifying the issue, he got to work. About an hour later, he had the part replaced and my sump pump functioning normally and much more quieter than it had been prior. He even cleaned out the basin the pump was sitting in and disposed of the yard debris that crept in. The homeowner and plumbing wisdom that he bestowed on our household was elite as well. Patrick is "our guy"! Thanks Patrick!"

Subcontractors questions, answered by experts

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.

In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The up-front cost could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.

On average, the cost to transform your garage into a workshop is about $2,000. The overall project cost depends on the type of workshop you want to build and its size. Regardless of the type of workshop, you’ll still need basic workshop spaces and equipment such as a workbench, cabinets, and space for storage and for working.

Many providers assist with obtaining necessary permits. Confirm with your contractor.
