Welcome to our profile. Integrated Electrical Solutions is a full service electrical house. We do great work, at a fair price. Our pricing is very simple: we charge a $175 service fee, and $150 per hour for Lead Electricians, $115 per hour for Second Electricians, and $85 to $95 per hour for Helpers. , plus parts for electrical, drain work and appliances. We service all brands of portable and stand by generators. Work before 6 am as well as night after 6pm, weekends and holidays is subject to additional charges. We normally charge $125 to clean dryer vents and that's it. We provide outstanding, well equipped mechanics, who know their jobs. YOU GET WHAT YOU PAY FOR- TOP SHELF FIVE START SERVICE. Integrated Electrical Solutions is a fully licensed and fully insured electrical company. We do emergency work 24/7, 365. When you want the best and you want it done right the first time, call us. thank you!

"The experience was not quite what I expected. I had clearly explained the scope—replacing 10-12 standard switches with smart switches giving model number/spec—and was hoping for a lump sum proposal, but they only offered hourly rates, which is understandable. They estimated it would take about 2 hours, but the job ended up taking over 4. While they mentioned having done similar installations before, they spent quite a bit of time reviewing instructions on site, which added to the time and cost. The final bill was over $800 for a couple switches, including a service fee and $10 for wire connector? (The switches come with connector) Just a heads-up to others: be sure to ask detailed questions about hourly charges and how time will be managed, especially for smart device installations."

Plumbing, HVAC, and electrical systems make your house livable. One minor issue with any of these systems can put your home at a standstill. In case you find yourself in this unfortunate situation, know that you can count on Gold Medal Service. For over 24 years, our company has been taking care of the homes of New Jersey residents through our top quality plumbing, HVAC, and electrical services. We are available 24 hours a day, 7 days a week to address even the most mind-boggling issues of your in-home equipment. From repairs, installations, and upgrades, our technicians are known for getting the job done right every time. We also provide upfront pricing with a full description of the service before commencing work to avoid any surprises down the line.

"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

"Contacted National Home Improvements regarding leaking patio roof and no follow up response to issue since last year of April 2023. Still awaiting to hear back. Seems like the rain gutter is sagging in the middle of the patio where the two joints meet and water is pooling there and possibly leaking through the seams as illustrated in the photo. Poor design concept. Really disappointed with customer service and quality of product especially for what we have paid for. They clearly don't care about taking care of their customers. I would never hire National Home Improvements again!!!"

Subcontractors questions, answered by experts

General contractors typically manage home renovation or build projects that last more than a week and involve various skilled tradespeople. Some examples include building a new home or barn, adding an extension or garage, or carrying out major room remodels involving extensive plumbing, electrical, and structural changes.

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.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.

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.

While some people are confident in their ability to replace concrete by drilling out the broken pieces and replacing them with bagged concrete, it’s possible to run into snags that make hiring a professional worth it. Trying to level concrete slabs can require special equipment, which can be pricey to rent and tough to operate. It's also crucial to contact your town's municipal office to ensure you are allowed to take on the project without a permit.
