Edit 10/13/20 due to overwhelming demand I am not taking on new work at this time. The best way to reach me directly is to call or text 603.401.4496 or email [email protected]. I am a lifelong Salem, New Hampshire resident, and have been working in the field of home renovations for 20 years. My background in furniture design and fine arts led me into General Contracting, kitchen and bathroom design, handyman services and home remodeling. From "Honey-Do Lists" to full kitchen, bathroom and basement remodels, my reputation for efficient, detail-oriented, and quality workmanship is something I am extremely proud of and strive to maintain. Your home is your biggest asset, and I consider it a privilege when my customers invite me into their homes to repair and renovate them.

"Mark is thorough, precise and extremely neat. Many contractors leave their mess behind but Mark is meticulous! I highly recommend him."

Home Security Systems questions, answered by experts

Costs depend on system type, labor rates, and additional features like smart integration or professional monitoring.

The biggest downside to a wireless security camera is that it's 100% reliant on Wi-Fi to capture footage at your home. Even when Wi-Fi is reliable, the range for wireless cameras may only be 200 feet or less. Drywall, brick, and other materials in your home can be enough to make your signal lag.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.

Yes, most pros encourage you to change your locks when you move into a new home. While the previous owner may hand you their keys, you have no way of knowing whether other copies exist elsewhere. Changing your locks as soon as you move in is a great way to ensure that you can enjoy new, fully functioning locks that will work with your unique key or code.

Faulty sensors, weak signals, false alarms, and control panel malfunctions are common problems requiring repair.
