Ready to cut the cord, and rabbit ears aren?t cutting it? Cables hanging all over your house, and you want them to disappear? WiFi just doesn?t reach upstairs? You?ve come to the right place! My services include: TV and FM antenna installation and repair, including in attics; old school cable fishing and concealment; installation and repair of coaxial, Ethernet, telephone, speaker, and other low voltage wiring, including repurposing existing cabling; TV wall mounting and cable concealment, especially difficult or unusual locations; limited satellite dish installation, repair, and removal, including Free-To-Air (FTA) dishes. (Sorry, no large C-band dishes, no warranty work on subscription service equipment.) I'm not an equipment dealer, so I won't be trying to sell you anything. I can provide a few items, as a convenience (e.g., antennas, bulk cable), but I?m ready to work with, or advise you on the purchase of your own equipment (e.g., routers, security cameras).

"Ken is a terrific worker and knowledgeable problem solver who took on my old house and my cramped crawl space without even a hint of hesitation or complaint. He worked efficiently and without a pause for more than 10 hours to get a job done in record time----it was much more involved than we thought, and he persisted and got it done, and done right. Thank you Ken! He's a real rarity amongst workmen, absolutely thorough, trustworthy and good natured in the face of all difficulties! A real gem, I'm so glad I hired him!"

"Jay was able to come early which worked for us. He assessed the problem with the leaking valve, offered 2 solutions with clear pricing and clear reasoning as to why he recommended the slightly more expensive one (much less likely to fail in the future!). He accomplished the work quickly, showed me the completed work, and showed me why the other valve had failed, AND the area was clean and dry when he was done. Throughout the visit he was pleasant, polite and respectful. Will be happy to use this company again!!!"

Generator Install questions, answered by experts

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

No, you shouldn’t use an extension cord to plug a generator directly into your home without using a transfer switch. That’s because systems like pumps and HVAC fans need a steady power source that might not be available directly from your generator alone. If you bypass the circuit breaker box, you risk damaging your electrical system, creating a risk of electrical fire or electrical shock to you or any workers repairing lines on your local electrical grid.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
