"Lenny and Lisa are great. During the demolition phase, Lenny took great care to cover our hardwood floors and cleaned thoroughly while removing the countertops and backsplash which really helped to keep the dust level down. Lisa recommended vendors for our granite, tile backsplash and sink - they were all so helpful. We have never done a kitchen renovation before and were a little anxious about the process and making choices. Lenny allayed our fears and was spot on with suggestions. Lisa was always available for communication and answering questions. The sub-contractors were all excellent, personable and professional. The whole job was finished ahead of schedule which allowed for our 18 month old granddaughter to come for an earlier visit! Overall we are thrilled with the outcome and will definitely use Apple Wood for future projects!"

Electrical for home addition or remodel installations FAQs

Because installing coax outlets involves working around existing electrical wiring and confirming proper grounding, many homeowners prefer to hire a licensed electrician. A professional completes the work safely, secures the line behind the wall, and ensures the installation meets local code, which reduces the risk of damage or future repairs.

You still need a coaxial outlet for most cable-based internet services. The modem draws its signal from a cable line that terminates at a dedicated wall jack. Once the modem is online, your Wi-Fi router can broadcast the signal throughout the home, so the outlet’s location doesn’t affect wireless performance. If an existing jack is damaged or in an inconvenient spot, an electrician can move it or install a new one to maintain a strong, reliable connection.

Coaxial cable loses signal strength the farther it runs. A 50-foot length introduces noticeable loss, and a 100-foot stretch can drop the signal by roughly 30%. A weaker signal can result in a fuzzy picture or slower internet speeds. To maintain high performance, limit cable length whenever possible, select the correct cable grade, and route it efficiently. If your layout demands an exceptionally long run, an electrician can install an inline amplifier to boost the signal and maintain picture or data quality.
