"We replaced the original roof on our house. I expressed my concerns about re-installation of the lightening rods to my roofer. We have had at least three direct hits since they were originally installed in 2013. My roofer called William who was very helpful. William offered to come out an make sure everything was 100% after re-installation. He came the day after I called and I'm glad he did. While the reinstall was the best he had seen (his words) there were issues after 5 year and 3 strikes that needed addressed. He fixed those and now I have a new roof and I am certain the lightening rods will work as intended. Highly recommend this company."

"Rough Diamond Construction Company did an excellent job remodeling my family room/basement. Nate's attention to detail and his expertise was well worth every dollar paid. He was always in contact with me as well as advocating for me when I had a water problem in my basement with the company who initially made the repair. Because of the water problem I experienced in the summer, I decided to have the entire room renovated - new floors, walls, ceiling, doors, etc. Nate and his crew were professional and efficient. The end result is that the room is absolutely beautiful. I would recommend Nate and his team to anyone - you won't be sorry."

"Simply amazing from start to finish! I can't say enough nice things about this company or the people that I dealt with. They were all professional, friendly and they did great work. They called me just minutes after I clicked their name on Angi's List and had someone out to give me an estimate and had my appointment date set in record time from most companies that I have dealt with for home improvement. I hate having people in my house working but I felt totally comfortable with them. The work they did was exceptional. We got a new power box (breaker box - whatever it's call) and a new meter and a couple of new outlets put in. We also got new smoke detectors throughout the house. They had to work around some issues and relocate a bit of pipe from out water filter system that was in their way. And they just took care of it without any complaints. I didn't have to do anything. They took care of it all and had the inspector come out and get it approved. I feel safe in my home now.

FAQs for smoke detector installation projects in Greencastle, PA

The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:

  • Video surveillance monitoring: $40–$65 per month

  • Smart home locks: $150

  • Smart home lighting: $15–$90

  • Smart smoke, fire, and carbon monoxide alarms: $35–$100

  • Smart thermostat: $130–$500

Yes, you should get a quote or an estimate from an electrician. Most electricians offer free estimates or quotes. When getting quotes, do your research and verify each electrician’s license. Get quotes from three different electricians to compare. If the prices or items listed appear different on the quotes, ask the electrician to clarify. Learning as much as you can about the electrical work you want done will help you get the most accurate estimate. 

Qualified, licensed electricians will charge from $50 to $100 per hour. The cost to hire an electrician for emergency visits may range from $100 to $200 per hour because this urgent service usually takes place during off hours and may require an electrician to leave or reschedule jobs they’re currently working on. Scheduling work on holidays or during periods of high customer demand, like after a major storm, will also lead to higher rates or extra fees.

An accredited, licensed smart home specialist should install your home automation system. For example, a qualified smart home specialist will belong to an organization like the Custom Electronic Design & Installation Association. Licenses for qualified technicians require the technician to demonstrate experience and pass state testing. If you’re ready to install a home automation system, consult multiple technicians in your area to compare services and prices and find the best fit for your job.

The average cost of a home automation system is around $950, but typically ranges from $200 to $1,700, depending on the brand, system features, system size, home size, and location. The highest-end home automation systems can cost anywhere from $10,000 to $150,000, including smart appliances like refrigerators, dishwashers, and ovens that require installing extensive wiring. Any subscriptions for maintenance services will also impact the cost of a home automation system.
